Résumé :

The research investigates if there is a relationship between a focus on improved safety and productivity. This relationship can help companies improve the approach in dealing with two variables that line managers battle with daily. Data was collected from 115 respondents and interview conducted with 6 senior managers in the petroleum industry. The research confirms that there is a relationship and that when a company focus on improving safety they could at the same time improve productivity. An investment on productivity could also improve productivity if they focus on it during design. These two variables support goal number eight of the United Nations sustainable development goals. The research also found that employees believe that the company is not doing enough to invest in safety and there is not enough belief in safety. The research also found that investing in productivity can also improve safety and employees and management with the right safety culture. Safety is a licence to operate and productivity is necessary for the sustainability of the business.

Howse, D. S. « Improved productivity in fusion welding : executive summary ». Thesis, University of Warwick, 2002. http://wrap.warwick.ac.uk/2149/.

Résumé :

This document is an Executive Summary of individual submissions of work that the author has submitted towards the degree of Engineering Doctorate. The work comprises three main themes, which can be demonstrated in a broader sense as contributing towards improved productivity in fusion welding: i) The use of active fluxes for Tungsten Inert Gas (TIG) welding. ii) An investigation into the reduction of porosity when Metal Active Gas (MAG) welding galvanneal coated steel sheet used in the automotive industry. iii) The use of high power Nd:YAG laser welding for the production of large diameter, long distance land pipelines. Active fluxes give improved productivity by increasing the penetration depth of the TIG welding process by the simple addition of a flux applied to the surface. Although the productivity benefits of the process had been proven through a joint TWIIindustry project, the mechanism by which the fluxes produced this improvement was not fully understood. The first theme investigated the mechanisms at work in providing increased penetration and concluded that the primary mechanism responsible for the action of the fluxes was not due to a change in the flow of the molten pool but, as others had suggested, due to arc constriction. This work contributed to a greater understanding of the welding process and, furthermore, a greater understanding of the potential opportunities and limitations of the process when designing new fluxes for other alloy systems. MAG welds in coated steel sheet used in the automotive industry are prone to porosity leading to high reject rates. The second phase of work reported here determined welding procedures capable of delivering low porosity welds developed through statistical experimental design. These procedures demonstrated how low porosity welds could be made using conventional MAG welding techniques on steels that had been galvanneal coated to provide corrosion resistance. The procedures developed could be easily implemented at high production rates in an industrial manufacturing environment to reduce defect levels, and thus costly repairs or high scrap rates. The third theme of the work demonstrated how Nd:YAG laser welding could potentially be used to replace conventional arc welding techniques for land lay of gas transmission pipelines. The application of a single laser fill pass, made at high production rates, could replace the use of multiple MAG welding stations greatly reducing the costs associated with pipeline fabrication. BP has claimed that half pipeline cost savings of up to $300 million dollars are achievable through the implementation of such a technique. The justification for the use of lasers in pipelines is discussed in terms of both technical and economic suitability. Preliminary experimental work showed that high power Nd:YAG laser welds could achieve productivity targets, although in order to reduce defects and achieve the necessary structural performance it would be necessary to combine laser welding with a MAG welding process.

Résumé :

Thesis (Mtech(Business Administration)--Cape Technikon, Cape Town, 2001
The researcher identified an absenteeism problem at the Cape Technikon Library and sees the effect of it on a daily basis. It is a costly and disruptive problem and places unnecessary pressure on staff that are at work. From the outset, companies might not realise the cost of absenteeism until they actually measure it. Absenteeism of other staff members create various problems such as low morale, increased stress, break in team work, etc. between the staff that are at work. To reduce the absenteeism rate, certain measures and control systems should be put in place. Absenteeism can either be addressed by putting a reward system in place or making use of punishment contingencies, or using a combination of both. If staff members see that other staff members get away with excessive absenteeism, they will soon follow. Within the context of the Cape Technikon Library, a culture of absenteeism has been created and it is not easy to break that culture. This study considered possible reasons for the absenteeism as well as possible solutions. To improve productivity and cost-effectiveness, the Gross Absence Rate (GAR) should be less than 3% (Van der Merwe: 1988:25). According to Van der Merwe (1988:25) an absence rate of 10% is extremely serious and any absence rate of more than 5% should be regarded as an indicator of a situation needing further investigation. An absence rate of less than 3% can be regarded as satisfactory, although capable of furtherimprovement. On some days the absenteeism rate at the Cape Technikon Library is approximately 12%.

Résumé :

Industry 4.0 is a collective name for several technological innovations that, when combined, among other things, provide an exponential potential for increased operational excellence in manufacturing. This thesis digs down into which technologies that are relevant in the context of predictive maintenance and how these can be integrated into existing theory in order to create value through increased e↵ectiveness. The primary findings can be condensed down into one general principal - uniformity. In order to leverage industry 4.0, and through it achieve a higher level of automatization, all data flow must be as canonical as possible. This is what allows both for bi-directional communication at scale, and higher-level decisionmaking algorithms to be deployed over a wide range of hardware.
Industri 4.0 är ett samlingsnamn för ett flertal tekniska innovationer vilka, tillsammans, möjliggör en potentiell förbättring av operational excellence som ökar exponentiellt mot antalet aopterade teknologier. Detta arbete dyker ned i vilka teknologier som skapar mest värde i kontexten predictive maintenance. Arbetet studerar även existerande orginatorisk teor och hur dessa kan slås samman. Det primära resultatet kan summeras som att fokus bör ligga på en canonical model för den data som genereras, och skickas ned till maskiner på fabriksgolvet. Uniform data spelar även en nyckelroll i att facilitera för beslutsfattande algoritmer då dessa annars enbat skulle gå att applicera på specifika maskiner.

Résumé :

The Thailand construction industry is the database for this research, which consists of three main sections. As there has been a lack of research in the construction industry in Thailand, firstly, structured questionnaires were distributed to project manager, foremen and craftsmen, to observe general construction productivity and to find out if a work-sampling study could be tailored to detect these problems. The results indicated that lack of materials, incomplete drawing and lack of tools and equipment have the greatest effect on construction productivity in Thailand, and so a work-sampling study can be tailored to detect these problems. Having confirmed that it is possible to undertake work-sampling to increase construction productivity, this thesis, secondly, has improved and clearly specified all the individual steps required to carry out a work-sampling study. In addition, this research has also reported the application steps of FDS. The work-sampling technique was applied to four construction cases and FDS was also carried out on two of the four sites. The results confirmed that a work-sampling study can highlight the productivity problems, and indicate how to overcome or alleviate them, and inferred that late start/early finish and crew imbalance are likely to be universal construction productivity problems in Thailand. In addition, these two techniques contribute to each other and should be implemented together. The final part of this study applied the Markov process to predict the results of worksampling at any particular periods of time in the future. This concept is not only able to predict the results, but also supports the principle of work-sampling which, if it is to be successful requires full support from management.

Résumé :

Meat and milk from sub Saharan African cattle systems tend to have high greenhouse gas emissions intensities; this is largely due to low levels of productivity. There is a need to increase production to meet an increasing demand for livestock commodities; driven by growing populations, and growing diet variation, as incomes and urbanisation increase. Without measures to reduce the emissions intensity of production, there will be significant increases in total greenhouse gas emissions. Therefore, cost-effective ways of reducing emissions intensity, whilst increasing productivity should be identified. This thesis looks to support this by providing an assessment of low-input to semi-intensified cattle production systems in Senegal, West Africa; where cattle populations are growing and efforts are being made to increase domestic milk production. The emissions intensity of protein from current production systems is calculated using a version of the Food and Agriculture Organization’s Global Livestock Environmental Assessment Model (GLEAM). Variation in emissions intensity is observed between current systems, which can be largely linked to feed ration quality and levels of protein productivity. Productivity improving interventions suitable for the study systems are identified, and their application to current systems modelled by altering input parameters within GLEAM. It is suggested that production systems could reduce emissions intensities by applying nutritional and health related intervention packages; through which the varying production systems could abate between 10% and 20% of their total greenhouse gas emissions whilst also making financial savings. A comparison between the current systems of production also suggests that changing the lower productivity systems to match higher producing systems would also offer substantial cost-saving emissions abatement. The thesis considers the key limitation to the use of GLEAM for modelling the application of nutritional mitigation measures, in that when nutritional improvements are made animal performance does not currently increase. Predicting how animals will respond to improved nutrition is challenging. However, a methodology is discussed, and is shown to have an important effect on the emissions abatement results. Subsequently, the thesis advocates further research to experimentally substantiate animal performance responses when nutritionally limited cattle are given improved feed regimes. Despite the study livestock keepers showing aspiration to improve the productivity of their herds, with subsequent potential to reduce greenhouse gas emissions, the thesis recognises that the abatement potentials suggested by modelling would be restricted by the reality of production system context and constraints. Key barriers to a realisation of the productivity improvements include: a lack of financial means, limitations to resource access and affordability, and requirement for information and training concerning productivity improving options. For realisation of productivity improvements the current barriers would require further investigation, the thesis helps identify what form interventions should take.

Résumé :

Dissertation submitted in fulfilment of the requirements for the degree Master of Technology: Quality in the Faculty of Engineering at the Cape Peninsula University of Technology
This research will focus on employee satisfaction in the workplace. The research will be conducted as a result of the high number of factory staff resigning due to unhappiness in their work environment. This transposes into not only productivity being lost, but also that the efficiency of the organisation is being compromised. The purpose of this research is to establish if employee satisfaction could serve as a catalyst for improved efficiency, productivity and customer satisfaction.The research will be conducted at Anchor Lining Systems (ALS). The company is based in Cape Town South-Africa and manufactures a concrete protection liner referred to as Anchor Knob Sheet (AKS). The product represents a „state of the art‟ robust concrete protection liner system. It is designed to protect concrete structures in chemically aggressive environments.The research question which will be researched to mitigate the research problem reads as follows: “What approach could be deployed to minimise employee dissatisfaction in a manufacturing organisation to improve its overall efficiency, profitability and customer satisfaction?”Applied research will be conducted in this thesis, as the research will be designed to apply its findings to solve a specific, existing problem. The research will furthermore fall in the social world as social science has to do with how things are, and why. The research, due to the fact that it would require intensive textual investigation will be theoretical in nature, which can be define as, “contemplative of the mind, on intellectual faculties”. Furthermore, theoretical research is commonly associated with the phenomenological paradigm, which is used to answer questions about the complex nature of a phenomena, often with the purpose of describing and understanding the phenomena from the participant‟s view. These concepts are also commonly referred to as the „qualitative paradigm‟.The proposed research in this dissertation would be of specific benefit to the manufacturing industry in South-Africa, due to the high levels of staff turnover being experienced in the industry due to employee dissatisfaction. Such high levels of turnover de-stabilises the industry in that key resources are lost to organisations. If turnover can be minimised by elevating the levels of employee satisfaction then efficiency, productivity and customer satisfaction can be exponentially improved.

Résumé :

Planning is the act of determining the steps necessary for an organization to obtain goals in the future. Planning takes on even more importance as competition increases and additional efficiency is needed. In todayâ s competitive business environment, any method that can be utilized to maintain an advantage over an organizationâ s competitors must be investigated. Organizations allocate time and resources dedicated to planning differently. Differences are directly related to the goal that is being planned for and the amount of time before the goal is to be met. This study was undertaken to determine what levels of planning and communication were present in the wood supply industry and to determine how information that was being exchanged was being used in these processes. During 2001, Virginia Tech Forestry Operations researchers completed a study to assess the current state of planning and communication in the industrial wood supply process and to identify opportunities for improvement. Researchers performed interviews with 169 individuals representing all segments of the wood supply system. Interviews were performed during the summer of 2001 in the southeast and northeast regions of the United States. The overall findings of this study showed that current planning in the wood supply system is primarily â reactiveâ rather than proactive, resulting in extremely short planning horizons for all segments of the wood supply chain. This is due in some part to the high degree of uncertainty facing the forest and logging industries in todayâ s business climate, but is also a result of a continuation of traditional business practices that promote inefficiencies in the wood supply chain. Frequent, short term changes in mill requirements, including delivery schedules, inventories, and specifications, drive many of the constraints to planning in the wood supply system. Thirty-five percent of the wood procurement organizations interviewed reported that the consumption mix at their mill often changed on a weekly basis, and 65% reported they typically receive only one or two weekâ s notice in advance of significant changes in mill wood requirements. Advances in communication technology, such as cell phones, are facilitating frequent verbal communications between all segments of the wood supply chain. These communication improvements are also a factor in reducing the planning horizons for suppliers. As consumers adopt and use these communications technologies they are being used to actively manage daily (rather than weekly, monthly) wood flows as â just-in-timeâ inventory management goals. While 60% of the loggers interviewed reported they communicated at least twice a week or more with their wood dealer or procurement forester, 70% reported that these communications were only â somewhatâ or â not helpfulâ in planning their production goals. More than 75% of the contract loggers interviewed know the location and characteristics of the next tract they will harvest less than one week before they move their equipment and begin harvesting operations. This common and wide-spread industry practice of delaying critical information to loggers with regard to tract allocation creates a barrier to effective operational harvest planning, and provides one of the greatest opportunities for substantial cost savings through improved planning and communications. Compensation rates for logging contractors are primarily determined (70%) through the application of consumerâ s logging cost models or dealerâ s â marketâ rates which facilitate little if any true negotiation for harvesting system cost items. These models are generally based on projected â averageâ production rates that do not reflect consumer-imposed constraints such as quota reductions, additional mandated moves, or tract allocation â mismatchesâ . Efficient and predictable wood flow is critical to a stable and profitable forest and logging industry. Mill management and wood procurement personnel should plan their wood requirements, inventory and delivery schedules on an annual basis and effectively communicate these plans to the appropriate suppliers to facilitate their (suppliersâ ) ability to conduct meaningful long-term strategic and tactical planning. Without adequate planning all participants of a system lose control and generate inefficiency. Proper planning reduces the likelihood that obstacles will dramatically affect the efficiency and corresponding productivity of these participants. The results are improved productivity and increased return on capital employed.

Texte intégral

Résumé :

The thesis treats roll pass design in wire rod rolling of stainless steel for sequences and series built up by two-symmetrical grooves. It is focused on predicting rolling flexibility, also called working range, as well as product quality. For analysing the flexibility a computer program has been developed. The minimum and maximum roll gap and corresponding bar areas for series of grooves including "oval", "round", "false round", "square" and "diamond" shapes are calculated. Six pass designs used in Swedish mills are analysed. Full-scale rolling is compared with laboratory experiments for the square-oval and false round (round)-oval series. The false round-oval series offers the largest working range and that the flexibility is smaller for pass sequences designed for high reductions. The false round-oval series are also acknowledged as a series for high quality steels and are usually better than the square-oval series having a tendency for defect formation. The thesis also includes high-speed rolling of wire rod in blocks. Here interstand tensions are utilised in order to keep the process stable. For obtaining the required dimensional tolerances of the product they are kept as low as possible. However interstand tensions could be used in order to increase the working range and move the product range towards smaller wire cross sections. For analysing this possibility, a narrow spread technology is utilised. At present time a practical problem is referred to the fixed gearings in the common blocks, which require a certain and given level of interstand tensions and corresponding reductions. This problem can however be solved by means of new block design and modern process control technology. Roll stands can be separately driven and controlled at very high speeds. Thus the eight stand blocks can be subdivided into four plus four passes blocks with a cooling line between enabling also higher productivity without violating the product quality because defect formations caused by a too high rolling temperature. The true working range of a series for a specific steel grade is however not only dependent on the possible spectrum of wire dimensions that can be obtained but might also depend on its ability to decrease or eliminate defects such as surface cracks. Thus, the behaviour of artificial V-shaped cracks in the longitudinal direction has been investigated and compared for the square-oval and false round (round)-oval series mentioned above. In agreement with other research works it was established that efficient rolling conditions for reducing the cracks are obtained when the cracks open up at the same time as their depth is reduced. If the V-shaped crack is closed by contact between its oxidized side surfaces the rolling schedule is not optimal for getting a high quality product. A deeper understanding of the experimental results was obtained by means of an FE-analysis

Résumé :

Thesis (MBA (Business Management))--Stellenbosch University, 2008.
ENGLISH ABSTRACT: The South African Government has set a target to halve poverty and unemployment by 2014. In an attempt to achieve this target a number of projects were initiated, one of which is the National Tooling Initiative (NTI). Local structures were established to encourage co-operation and competitiveness among the Small Micro and Medium Enterprises (SMMEs) by using the cluster concept. Consequently the Western Cape Tooling Initiative (WCTI) was formed to focus on and address the needs of the toolmakers in the Western Cape. It was highlighted during the interview with the Chief Executive Officer (CEO) of the WCTI that some of the toolmakers are limited in terms of the size of orders they could handle due to lack of capacity. Discussions and research showed that in addition to the cluster initiative, a model such as the Order Fulfilment Process (OFP) could be used to encourage toolmakers to play a role in the activities within the OFP which they are strong in and collectively tender for contracts which they cannot fulfil on their own. Coupled to the OFP, it was decided that activity based costing would be used to assist with the cost allocation of the activities along the OFP. Furthermore, some of the activities within the OFP would be centralised i.e. order taking and invoicing, while others would be decentralised i.e. manufacturing and distribution. The research study showed that although the office of the WCTI is fully established, there is a need to better understand and analyse the actual state of the toolmakers, their profile and capability. Once this information is available, the WCTI would be in a better position to make meaningful decisions about the appropriate plan of action. Concurrently, the WCTI need to also learn about the business opportunities that are available to the toolmakers and begin to exploit them. The aim of the study was to help improve the performance of the toolmakers through co-operation by using the order fulfilment process model complemented by activity based costing. The objective of the research project was to develop a framework that should be used by the WCTI to encourage co-operation among the toolmakers to improve their competitiveness.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse regering het aan hulself die doelwit gestel om teen 2014 armoede en werkloosheid te halveer. In ‘n poging om hierdie doelwitte te bereik, is ‘n aantal projekte van stapel gestuur, waarvan die “National Tooling Initiative” (NTI) een is. Plaaslike strukture is gevestig om samewerking en mededinging aan te moedig tussen die klein-, mikro- en medium- sake-ondernemings (SMMEs) deur die gebruik van ‘n groeperingskonsep. Gevolglik is die “Western Cape Tooling Initiative” (WCTI) tot stand gebring om te fokus op die behoeftes van die gereedskapmakers in die Wes-Kaap en hul behoeftes aan te spreek. In ‘n onderhoud met die Hoof Uitvoerende Beampte van die WCTI is aandag daarop gevestig dat sommige van die gereedskapmakers beperk word in terme van die grootte van bestellings wat hulle kan hanteer as gevolg van hul gebrek aan kapasiteit. Gesprekke en navorsing het getoon dat ‘n model soos die bestellingvoltooingsproses (Order Fulfilment Process (OFP)) gebruik kan word om gereedskapmakers aan te moedig om ‘n rol te speel in die aktiwiteite binne die OFP waarin hulle sterk is en gesamentlik tenders in te dien vir kontrakte wat hulle nie op hulle eie kan hanteer nie. Tesame met die OFP, is daar besluit dat aktiwiteitsgebaseerde kosteberekening gebruik sou word om te help met die bepaling van koste-allokasie van die aktiwiteite binne die OFP. Verder sal sommige van die aktiwiteite van die proses gesentraliseer word, naamlik die neem van bestellings en fakturering, terwyl ander gedesentraliseer sou word, naamlik vervaardiging en verspreiding. Die navorsingstudie het getoon dat, alhoewel die kantoor van die WCTI ten volle gevestig is, daar steeds ‘n behoefte bestaan om die werklike toestand van die gereedskapmakers, hulle profiel en kapasiteit te begryp en te ontleed. Wanneer hierdie inligting beskikbaar is, sal die WCTI in ‘n beter posisie wees om betekenisvolle besluite te neem rakende die gepaste plan van aksie. Verder moet die WCTI ook hulself vergewis van die sakemoontlikhede wat vir die gereedskapmakers beskikbaar is en dit begin benut. Die oogmerk van die studie was om die werkverrigting van die gereedskapmakers deur samewerking te verbeter deur middel van die OFP wat ondersteun word deur aktiwiteitsgebaseerde kosteberekening. Die doel van die navorsingsprojek was om ‘n raamwerk te ontwikkel wat deur die WCTI gebruik kan word om samewerking onder die gereedskapmakers aan te moedig en hul mededingendheid te verbeter.

Résumé :

Agriculture is central to the economy of Kenya, but as the population dependent on the same land grows, farmers have been compelled to develop more intensive practices to produce similar yields as in the past. Investments in agricultural research and technology facilitate this intensification and have historically resulted in substantial gains. However, efforts to promote effective transfer of new technologies and methodologies have been stifled by financial challenges to traditional agricultural extension delivery approaches. Extension services involve significant face-to-face contact in farmer fields, through farmer field schools, or at regional events. However with rising costs, the demand for more mobile and adaptable mediums is apparent. This study examines the potential for new methods of knowledge and technology transfer and diffusion of innovation within Kenya, most notably the use of mobile phone services. In order to frame the potential of such services, a national level macro-econometric analysis was undertaken to assess the effects of investments in agricultural research on agricultural gross domestic product. These results were then overlaid on an analysis of 14 case studies examining the effects and challenges of agricultural extension in East Africa. Three potential services, Awaaz De, FarmFox, and Community Knowledge Workers (CKW), were then assessed on a capabilities standard in the context of the rise of the mobile communication markets in Kenya for potential application to extension services. The results indicate that agricultural research is strongly correlated with growth in agricultural GDP and that effective extension services have strongly facilitated that in the past. However, limited flexibility, lack of farmer input, and high costs limit that potential contribution to growth. Mobile communication services may be part of the solution; capabilities of Awaaz De, FarmFox, and CKW are promising, but further research is needed to accurately recommend a service for Kenya’s extension services.

Résumé :

The safety record of most petrochemical industries in the world and Nigeria in particle, has not been able to come down to the maximum allowable range of 0 - 0.1 percent of tolerance on recordable injuries, due to increasing failure rates of equipment within the plant. Investigations on the maintenance audit carried out on the Nigerian Gas Company (NGC) revealed that 85 percent of such failures are directly linked to improper adaptability of an effective maintenance management strategy and plan within the petrochemical industries in Nigeria. Equally, the growth and continuous operation of any plant depends to a large extent on the maintenance of the equipment that refines the Crude Oil and natural Gas. As such, various maintenance management systems have been used over the years for the actualisation of the above purpose but with minimal success. This is evident in the fact that the level of maintenance performance of most Nigerian Petroleum Companies is always on the corrective maintenance model, which indirectly implies that the plant normally breaks down before maintenance management is applied. A critical look at the deficiency of improper adaptability of these maintenance management plans have conspicuously manifested in five major categories of maintenance failures which includes the following; * Failure of safety critical equipment due to lack of maintenance * Human error during maintenance * Static or spark discharge during maintenance in an intrinsically unsafe zone * Incompetence of maintenance staff, and * Poor communication between maintenance and production staff. These gaps as identified in this research must be corrected in the Nigerian Gas Industry if meaningful progress is to be made. Gas – To – Liquid technology is a very complex technology and with natural gas as the basic raw material, the technology not only looks intimidating but also is full of potential hazards. People are naturally afraid of the complex nature of gas in a confined environment (because of its highly combustible nature), its gaseous state makes it more complex for it to be kept under control and at the same time be moved from one form to another at different temperatures and pressures. The maintenance audit carried out on the Nigerian Gas Company (NGC) revealed some major loopholes in the maintenance management strategies adopted in the country. The audit reveals that the degree of adherence to conditions attached towards the maintenance management strategy of this equipment (in this case Gas field equipment) was too poor. Based on the above, this research is meant to improve the existing maintenance management strategy, by developing a Maintenance Management Strategy (MMS) that will be suitable for gas field equipment in the Escravos Gas–To– Liquid (EGTL) plant, planned to be commissioned in Nigeria early 2011. The need to research the above mentioned Maintenance Strategy became imperative due to the fact that the rate at which most of the petrochemical plants in the world are being gutted by fire, mainly due to poor maintenance management systems is alarming. This research work proffered solutions that will reduce or completely eliminate the highlighted problems above. This was based on investigations and analysis carried out in the chosen research area. Models were developed for the actualization of this Improved Maintenance Management Strategy (IMMS), so that the desired safe operability of the gas field equipment in the Escravos Gas–To– Liquid (EGTL) plant will be achieved without maintenance failure of any kind.

Résumé :

The U.S. Bureau of Labor Statistics reports that millennials will soon represent 46% of the workforce. The anticipated changes in the workforce are of great concern to business leaders who may manage individuals from different generations. The purpose of this multiple case study was to explore the strategies that administrative leaders in an advisory group of community-based organizations and educational institutions used to improve the productivity of a multigenerational workforce. The conceptual frameworks that grounded this study were the social constructivist perspective and generational theory. Data were collected from semistructured interviews to elicit narratives from 6 administrative leaders from 6 different nonprofit organizations selected via purposive sampling throughout the northeast region of the United States with experience improving the productivity of a multigenerational workforce. Data also came from a review of company documents and a reflexive journal. Data analysis entailed coding, identifying relevant themes, using Yin's 5 step analytic strategy approach, and member checking to strengthen the validity of the interpretations of participants' responses. Two principal themes emerged from the data: effective leadership strategies and essential retention strategies to improve productivity. The overall analysis of the 2 principal themes revealed the importance of communication, teamwork, training, work-life programs, recognition, knowledge sharing, and feedback in improving the productivity of a multigenerational workforce. Findings from this study may contribute to social change because chief executive officers (CEO) may use the strategies to implement corrective measures to positively influence the productivity of a multigenerational workforce.

Résumé :

An increase in the global competitiveness has forced manufacturing organisations to re-look their facility from a labour productivity standpoint. Leveraging a manufacturing operation into a competitive avantage must at all times support the organisation’s objective. It is therefore critical that the operation reviews its strategy so that it fulfils the ever changing needs in the market. Purpose – The main objective of this research is to identify the critical success factors to improve direct labour efficiency within Johnson Controls Automotive South Africa (Pty) Ltd (JCI). Design/methodology/approach – A combination of a comprehensive literature review and visits to the Uitenhage plant and head office were employed in the study. JCI practices were observed to highlight the level of direct labour productivity. This was followed by interviewing relevant and key personel who had an involvement in achieving direct labour productivity in the plant. A questionnaire-based research approach was adopted for this purpose and a total of 83 valid survey responses were received from staff in the Uitenhage plant, together with head office staff who directly supported the plant. The questionnaire was designed to identify and test perceptions of employees, regarding the factors of production, identified as sub variables. The research aim was to determine the most practical and effective strategies to improve direct labour productivity. Results were analysed and interpreted after which recommendations were formulated. Findings – Several critical success factors identified as sub variables were tested to understand their impact on direct labour productivity. Empirical results showed that organisational culture, leadership culture, employee engagement, communication and skills, development and training, had a significant effect on direct labour productivity. Respective ratings of these elements were discussed with the focus of improving this going forward. Research limitations/implications – Continued scepticim within JCI about the benefits of direct labour productivity to their business is one of the fundamental limitations this research faces. Originality/value – The novelty of the research project stems from the realization of key factors contributing to the improvement of direct labour productivity within the JCI enviroment. The results would provide JCI with indicators and guidelines for a successful implementation of direct labour productivity initiatives in the Uitenhage plant.

Résumé :

Thesis (MTech (Construction Management))--Cape Peninsula University of Technology, 2016.
This research was carried out to assess the extent to which supervisory motivational strategies can transform construction workers to perform higher levels of productivity. While worker motivation has been proven to improve productivity globally, motivation was rarely implemented in South African conditions. This study gauges the construction workers’ viewpoint on how supervisory motivational strategies can improve worker productivity. A pilot study was conducted in the initial stage of the study to gain more insight into the study. A qualitative research approach was employed using a semi-structured questionnaire to interview construction workers including bricklayers, plumbers, concrete workers, electricians and earthworks workers. The interviews were done in Bellville in the Western Cape at two conveniently selected construction companies. The data was analysed using content data analysis. Most prevalent in the findings of this study is the fact that the workers agreed that a lack of supervisory motivational techniques negatively impact their productivity. This information was helpful in setting up the questionnaires for the main study.

Résumé :

FPGA implementation tool turnaround time has unfortunately not kept pace with FPGA density advances. It is difficult to parallelize place-and-route algorithms without sacrificing determinism or quality of results. We approach the problem in a different way for development environments in which some circuit speed and area optimization may be sacrificed for improved implementation and debug turnaround. The PATIS floorplanner enables dynamic modular design, which accelerates non-local changes to the physical layout arising from design exploration and the addition of debug circuitry. We focus in this work on incremental and speculative floorplanning in PATIS, to accommodate minor design changes and to proactively generate possible floorplan variants. Current floorplan topology is preserved to minimize ripple effects and maintain reasonable module aspect ratios. The design modules are run-time reconfigurable to enable concurrent module implementation by independent invocations of the standard FPGA tools running on separate cores or hosts.

Résumé :

Recent research suggests that democratising the workplace is an effective way of improving productivity and wellbeing. But few studies have focussed on how to democratise the workplace. This study aims to explore how organisations can democratise the workplace via employee reward strategy, and how this impacts productivity and wellbeing. I hypothesised that a ‘high road strategy’ to employee reward – maximising value rather than minimising cost – would be the most effective way of improving workplace productivity and wellbeing. I also hypothesised that reward strategies in the Nordic countries, which tend to resemble a high road strategy, would be more effective than reward strategies in the UK. I used quantitative analyses on the European Company Survey 2019 data set, exploring different components of a high road reward strategy as predictors of productivity and wellbeing. My results suggested that a high road strategy to employee reward does improve workplace productivity and wellbeing. The strategy consists of maximising employee representative influence (via frequent meetings with management) and reward system comprehensiveness (via emphasis on pay based on company performance); it does not require broad collective bargaining coverage. Nordic reward strategies were more effective than UK strategies: perhaps due to Nordic two-tier bargaining systems facilitating employee representative influence and an emphasis on pay based on company performance. Future research should explore other ways of maximising employee representative influence, as well as other components of a high road reward strategy.

Résumé :

The worldwide software project failure rate, based on a survey of information technology software manager's view of user satisfaction, product quality, and staff productivity, is estimated to be between 24% and 36% and software project success has not kept pace with the advances in hardware. The problem addressed by this study was the limited information about software managers' experiences with data-driven decision making (DDD) in agile software organizations as a tool to improve software development productivity. The purpose of this phenomenological study was to explore how agile software managers view DDD as a tool to improve software development productivity and to understand how agile software development organizations may use DDD now and in the future to improve software development productivity. Research questions asked about software managers', project managers', and agile coaches' lived experiences with DDD via a set of interview questions. The conceptual framework for the research was based on the 3 critical dimensions of software organization productivity improvement: people, process, and tools, which were defined by the Software Engineering Institute's Capability Maturity Model Integrated published in 2010. Organizations focus on processes to align the people, procedures and methods, and tools and equipment to improve productivity. Positive social change could result from a better understanding of DDD in an agile software development environment; this increased understanding of DDD could enable organizations to create more products, offer more jobs, and better compete in a global economy.

Résumé :

Two computer simulation models were developed to address harvest system - stand assignment and wood flow variability problems in the southeast United States. The Harvest System Assignment (HSA) model is used to evaluate the impact of a particular stand assignment on harvest system effectiveness and is designed to assist with harvest system assignment decisions. Four general harvesting systems: manual, mechanized, shovel and cut-to-length can be modeled to harvest timber, from standing trees to processed logs loaded on to trucks. Model testing showed that as terrain, tract and system characteristics changed, the effectiveness of each of the four systems varied. The most effective system can be determined for any combination of terrain, tract and system characteristics. The model output shows production potential as well as cost per unit, and identifies the causes and magnitude of inefficiency. The Machine Allocation (MA) model is used to evaluate the potential of a given machine combination and is designed as a research tool to investigate the cause and impact of machine interactions. This model has a defined system structure and can incorporate up to five machines for each of three phases in the harvesting operation: felling, skidding and processing. Particular system configurations can be evaluated and possible improvements to machine combination determined. The HSA model is a widely applicable tool that will be available for industry in the southeastern United States. It has utility for training of personnel and for operational use. The MA model is a detailed tool that will be used in a research capacity to advance harvesting system management.

Résumé :

Research questions included: how much do company training programs appear to change quality, productivity, or employee involvement; and what changes might increase the effectiveness of quality/productivity training programs? An extensive survey instrument yielded fifteen useable replies from selected companies with participative programs in fourteen industries.Fourteen locations reported improved quality or productivity.Participative programs were often integral parts of quality/productivity programs. Sane locations operated two to five programs simultaneously.Training programs were judged as important contributors to major improvements in quality, productivity, or employee involvement. most locations did not attempt to estimate rate of return on training costs. Reported total training time ranged from 17 to 264 hours per employee. Five locations recommended same amount of training effort for all employees. Testing was seen as essential for skill training.Study recommended: management commitment; "awareness training" needs skill-building; customized programs; corporate resources or consultants to expedite application of new skills; only well-qualified, well-prepared trainer/facilitators; determination of training effectiveness; training program participation rewards.

Cataloged from PDF version of thesis.
Includes bibliographical references (pages 66-67).
The retail landscape is rapidly changing as evolving consumer habits are resulting in smaller batch quantities and shorter lead times, requiring Li & Fung to have a more digitally connected, nimble vendor base. Li & Fung uses a supplier network of thousands of garment factories around the world, the majority of whom are still capturing quality and production data manually, resulting in incomplete and inaccurate records. Factories see the value in making their operations digital, but most are low margin businesses that do not have the capital to make significant investments. This project is focused on the development of a cost-effective, digital tool to capture quality and production data at the end of a production line. This new tool will: -- Allow managers to quickly access real-time data analytics on their factory, -- Enable factories to make immediate root cause corrections in the sewing line, -- Serve as a gateway for Li & Fung to more proactively manage its vendor base,--
Give Li & Fung visibility to eliminate unnecessary inspection activities and reduce costs. The project began with an initial hardware prototype created in 2017 that evolved into the Phase One version of a mobile application which was delivered in early 2018. User testing was performed in three factories in India and Malaysia, where feedback was incorporated into a comprehensive redesign in Phase Two. The thesis will detail the needs and challenges from both the factory and Li & Fung viewpoints, and how this digital tool seeks to address them. For garment factories, the tool is cost-effective and simple, enabling factories to become digital in a very accessible way. The tool introduces garment factories to technology and Internet of Things without over-complicating their operations.
For Li & Fung, the tool provides much-needed insights into the actual performance of the vendor base, allowing Li & Fung to achieve many of its strategic initiatives related to inspection cost reduction, vendor selection, and production tracking.

Résumé :

A series of field, rainshelter, growth cabinet and modelling studies were conducted to investigate hot pepper response to different irrigation regimes and row spacings; to generate crop-specific model parameters; and to calibrate and validate the Soil Water Balance (SWB) model. Soil, climate and management data of five hot pepper growing regions of Ethiopia were identified to develop irrigation calendars and estimate water requirements of hot pepper under different growing conditions. High irrigation regimes increased fresh and dry fruit yield, fruit number, harvest index and top dry matter production. Yield loss could be prevented by irrigating at 20-25% depletion of plant available water, confirming the sensitivity of the crop to mild soil water stress. High plant density markedly increased fresh and dry fruit yield, water-use efficiency and dry matter production. Average fruit mass, succulence and specific leaf area were neither affected by row spacing nor by irrigation regimes. There were marked differences among the cultivars in fruit yields despite comparable top dry mass production. Average dry fruit mass, fruit number per plant and succulence were significantly affected by cultivar differences. The absence of interaction effects among cultivar and irrigation regimes, cultivars and row spacing, and irrigation regimes and row spacing for most parameters suggest that appropriate irrigation regimes and row spacing that maximize productivity of hot pepper can be devised across cultivars. To facilitate irrigation scheduling, a simple canopy cover based procedure was used to determine FAO-type crop factors and growth periods for different growth stages of five hot pepper cultivars. Growth analysis was done to calculate crop-specific model parameters for the SWB model and the model was successfully calibrated and validated for five hot pepper cultivars under different irrigation regimes or row spacings. FAO basal crop coefficients (Kcb) and crop-specific model parameters for new hot pepper cultivars can now be estimated from the database, using canopy characteristics, day degrees to maturity and dry matter production. Growth cabinet studies were used to determine cardinal temperatures, namely the base, optimum and cut-off temperatures for various developmental stages. Hot pepper cultivars were observed to require different cardinal temperatures for various developmental stages. Data on thermal time requirement for flowering and maturity between plants in growth cabinet and open field experiments matched closely. Simulated water requirements for hot pepper cultivar Mareko Fana production ranged between 517 mm at Melkassa and 775 mm at Alemaya. The simulated irrigation interval ranged between 9 days at Alemaya and 6 days at Bako, and the average irrigation amount per irrigation ranged between 27.9 mm at Bako and 35.0 mm at Zeway.

Résumé :

Three experiments were conducted to explore the effects of gasified biochar on contrasting temperate soil types in East Anglia, an agricultural area in eastern England, with a focus on the influence of soil properties. In a laboratory experiment comparing eight dissimilar soil types, adding up to 2.5% biochar improved field capacity by up to 42% (15% on average) and available water capacity by up to 48% (22% on average), but silty soils were less responsive. BD was reduced by up to 19% (10% on average). In a three-season outdoor pot trial with spring wheat (Triticum aestivum), four soil types were treated with biochar (at 0%, 0.1%, 0.5% & 2.5%). Biochar affected crop yield and soil properties, mainly positively, especially pH, CEC, base cations, field capacity, saturated hydraulic conductivity and some micronutrients. Positive yield responses appeared to be predominantly due to the influence of biochar on soil hydrology, increasing water-holding capacity on sandy soils in dry weather, while improving infiltration during excessively wet weather on a silty clay loam. In a trial on three contrasting soils in one field, cropped with winter barley (Hordeum vulgare), biochar (at 0, 50 t ha–1 & 100 t ha–1) had a range of predominantly positive effects. There were no significant increases in crop yield in this well managed agroecosystem, but variables which responded significantly included pH, some nutrients in the soil and in the crop, and grain moisture content. There was also evidence that biochar improved grain quality by reducing grain protein content on sandy soils, and increasing it on loam, keeping it within the tolerable limits of the malting barley industry in both cases. Potentially toxic elements (PTEs) within the barley grain (Zn, Cu, As, Ni, Cd and Cr) were not raised to levels critical to food safety. The overarching conclusion is that soil type, as defined by its physical, chemical and biological characteristics, is highly influential with respect to a range of effects that BC has on soil properties and crop responses, and that such characteristics need not only to be factored into future BC research, but should be the focus of studies aimed at identifying critical threshold values.

Résumé :

Employee engagement is the main topic of discussion among researchers and managers for over 24 years. Managing employee engagement is critical to the success of an organization, but 85% of manager's struggle with engaging employees. The purpose of this single case study was to explore employee engagement strategies that credit union managers use to increase productivity and organizational effectiveness. Expectancy theory was used to explore employee engagement, performance, and motivation of people in the workplace. Data were collected using semistructured interviews and observations with 6 credit union managers and company documents using thematic coding. Analysis of the data revealed that, among these credit union managers, effective communication, training and coaching, and rewards and recognition are management strategies required to improve employee engagement, productivity and organizational effectiveness. These findings may provide credit union managers with guidelines to measure and evaluate the effectiveness of engagement strategies to fit the culture of the credit union. The results of this study may provide credit union managers with guidelines on the causes of disengagement and how employee engagement could be improved within the organization. Researchers may consider conducting a multiple case study that include other credit unions within Louisiana to understand the similarities and differences between strategies used to engage employees. The results of this study may impact positive social change by improving the competitive environment of the credit union industry through engagement within community and society.

Résumé :

Lean philosophy is based on the continuous quest to improve the organisation‟s processes by creating a culture and operating principles which eliminate all non value adding activities within organisation„s processes. Manufacturing firms consider the adoption of the Lean tools as basic requirements for achieving World Class operational excellence or Best Practice. For some time, lean has been used by the manufacturing organizations. Most organizations understand that lean will help them survive global competition and stay in business. The objective of this study is to investigate how lean manufacturing tools can be used to improve efficiency and enhance the embedding of a continuous improvement culture in the South African Revenue Service Enforcement Audit Port Elizabeth. The activities that took place in Enforcement Audit Port Elizabeth from September 2010 until 31 October 2011 were observed. During the study, an introductory presentation by the researcher was made to Regional Enforcement Management and staff in general, the presentation was to introduce the study highlighting different Lean tools. Thereafter the Port Elizabeth audit staff members were engaged formally, using surveys to assess their underlying mindset and behaviour as well as informally, using unstructured interviews to solicit more information on activities taking place and the reasoning behind certain actions. The results of the survey and observations are analysed and interpreted.

Résumé :

This research was conducted within the context of smallholder livestock production and government attempts to improve this through a transfer of technology approach. Participatory action research (PAR) was used to enable action for change to emerge, while the research provided understanding and a basis for this action. Tombolo village in South Sulawesi, Indonesia was the location for this research, which first identified the problems and needs of the farmers, and then participatively developed strategies to meet these needs. Fodder security throughout the year was found to be the major constraint to cattle production. Forage technology was introduced, including fodder tree legumes and grasses, resulting in improved livestock production and many associated livelihood benefits. The introduction of these new technologies was adapted by stakeholders to local issues and needs. The extension services had previously aimed to improve livestock production through breeding and veterinary health measures, and had assumed that sufficient fodder was available for livestock. The formation of a learning group of farmers, who used group discussion to set their own agenda, was employed to identify this shortcoming, and how to sustainably overcome it. Participants were able to apply their experience and enhance their cognitive skills to find new meanings and knowledge to plan and take actions to improve their practice and situation. This thesis documents the process of change required to move from a “Transfer of Technology” approach to a “learning approach”. The research has shown that there is considerable potential for the application of PAR to rural community development in Indonesia. More specifically in Tombolo village PAR enabled farmers and extension staff to be empowered by becoming active participants in the research process and take action to improve their own practice. It helped them to analyse the situation to make the technology more appropriate, while also learning how to change the extension methods used towards one in which all stakeholders became partners in developing their situation

Résumé :

Epiroc manufactures and develops equipment for the mining and infrastructure industry. This thesis has been performed at Epiroc Underground Rock Excavation (URE) in Örebro, the company’s largest production unit for underground machines. In this project MH machines (material handling) have been investigated, i.e loaders and trucks. These machines are currently being built at the factory area in central Örebro and subsequently quality controlled in the Kvarntorp mine before they are finally delivered to the customer. The project aims to evaluate how current test methods in the mine could be minimized and, in the future, removed for certain machine types. Today the machines passes six steps between final assembly and delivery, which results in an extended lead time. The machines are started up at the pressurizing station before they are ready for the quality control, i.e testing. The machines are then transported to Kvarntorp, about 20 kilometers from the factory, before the test operators from Epiroc conducts the testing. Each machine type has machine-specific checklists which means that the test operator performs both visual inspection as well as test drive in order to verify the machine’s overall quality and performance. The current test procedure causes machine damages and the mining environment makes it necessary to perform both re-painting and washing. Summarized, the current test procedure leads to increased costs, increased amount of rework and extended lead times. In addition, the machine handling between the factory area and Kvarntorp involves logistical challenges. The work began with a literature study where the focus was on change management, flow efficiency and total quality management. Subsequently, a current state analysis was carried out in order to map the current structure and it’s problem areas. Identified problems included extended lead time, machine damages (paint, tires, bucket, snow) and work environment. All together, these areas lead to increased costs for the afterflow. These problems were categorized into three main problems; test procedure, environment and economy. To seek for improvements, three study visits were carried out; Volvo CE Arvika, Komatsu Forest Umeå and Epiroc SED Örebro. The inspiration was used to create an optimized test facility at the factory area. The work resulted in a solution where all areas are improved, i.e lead time, machine damages and work environment. A new test procedure based on an improved visual inspection, new bucket test and a succeeding test drive on a chassis dynamometer has eliminated the need for the Kvarntorp mine. With the new test facility the machine damages have been eliminated and the working environment for the affected people has improved considerably. Furthermore, the lead time is also heavily reduced. All together, the improvements results in large annual savings, which in turn gives relatively short pay back time. Epiroc is recommended to invest in both short and long term solutions where the short term can be implemented before the new test facility is finalized. In a short term perspective it is important to create a good dialogue between test operators and assemblers, switch to digital checklists and to remove the currently mandatory drag test. In longer term, Epiroc should implement a quality team, invest to increase data access and finally invest in the test facility.
Epiroc tillverkar utrustning för borraggregat samt bergbrytnings- och anläggningsindustrin för både ovan- och underjordsapplikationer. Detta examensarbete har utförts vid Epiroc Underground Rock Excavation (URE) i Örebro, företagets största produktionsenhet för underjordsmaskiner. För detta projekt har så kallade MH-maskiner (material handling) undersökts, det vill säga lastare och truckar. Dessa maskiner byggs idag på fabriksområdet i centrala Örebro och kvalitetskontrolleras därefter i gruvmiljö i Kvarntorp innan de slutligen levereras till kund. Projektet syftar till att utvärdera hur nuvarande testmetoder i gruva skulle kunna minimeras och framåt även tas bort för vissa maskintyper. Dagens upplägg innebär att maskinerna passerar sex steg mellan slutmontering och leverans, något som medför en förlängd ledtid. Maskinerna startas upp vid tryckställning och blir därigenom klara för kvalitetskontroll, så kallad provning. Maskinerna transporteras då till Kvarntorp, cirka 20 kilometer från fabriken, innan provare från Epiroc genomför provningen av dem. Varje maskintyp har maskinspecifika cheklistor som innebär att provaren genomför både visuell inspektion och provkörning för att verifiera maskinens övergripande kvalitet och prestanda. Nuvarande provningsprocedur orsakar skador på maskinerna och gruvmiljön gör att både lackering och tvätt blir nödvändigt för att uppnå önskvärd nivå innan leverans. Sammantaget leder nuvarande provningsprocedur till förhöjda kostnader, ökat omarbete och förlängd ledtid. Dessutom innebär maskinhanteringen mellan fabriksområdet och Kvarntorp logistiska utmaningar. Arbetet inleddes med en litteraturstudie där fokus låg på förändringsledning, flödeseffektivitet och offensiv kvalitetsutveckling. Därefter genomfördes en grundlig nulägesanalys för att kartlägga nuvarande upplägg och problemområde. Identifierade problem inkluderade förlängd ledtid, maskinskador (lack, däck, skopa, snö) och arbetsmiljö. Sammantaget leder dessa områden till kraftigt förhöjda kostnader för efterflödet av dessa maskiner. Dessa problem kategoriserades till tre huvudproblem; testprocedur, miljö och ekonomi. För att söka förbättringsalternativ genomfördes tre studiebesök; Volvo CE Arvika, Komatsu Forest Umeå och Epiroc SED Örebro. Inspirationen användes till att utfroma en, för URE, optimerad testanläggning i anslutning till fabriksområdet. Arbetet resulterade i en lösning som innebär förbättringar på alla områden, det vill säga ledtid, maskinskador och arbetsmiljö. Genom ett nytt flöde, med förbättrad visuell inspektion, nytt skoptest och provkörning på chassydynamometer, har behovet av Kvarntorp eliminerats. Med den nya anläggningen är maskinskadorna eliminerade och arbetsmiljön för berörda har förbättrats avsevärt, dessutom med kraftigt sänkt ledtid. Sammantaget resulterar förbättringarna i stora årliga besparingar. Epiroc rekommenderas att satsa på både kort- och långsiktiga lösningar där de kortsiktiga kan implementeras innan den nya testanläggningen tagits i drift. Viktigt på kort sikt är att skapa en bra dialog mellan provare och montörer, övergå till digitala checklistor samt att frångå det idag obligatoriska dragtestet. På längre sikt bör Epiroc implementera ett kvalitetsteam, satsa på att öka datatillgången samt att investera i testanläggningen.

Résumé :

This research investigated a queuing theory known as Erlang-C and its applicability in its use in central sterile supply. Erlang-C was used to calculate human resource needs in real time to encourage effectiveness in preparing trays for surgery. No consistent way of organizing tray preparation for surgery in a hospital currently exists. Efficiency in preparing trays is the goal of this study. Once surgical instruments are used, they need to be organized in sterilizable trays by a sterile processing technician before being sterilized. This study examines the actual versus the predicted output. The current situation can be described in three parts. First, there is no existing system to mathematically define the process of quality when preparing a surgical tray. There is no currently existing system to describe what theoretical productivity (benchmark) in tray preparation consists of. There is no currently existing system to describe how many technicians are needed to complete the surgical trays necessary for one day of surgery. There are several different types of sterilizable trays and the number and complexity of instruments in each of these types of containers (small, medium or large) varies. The current process is facilitated by a program called ABACUS with VIA Embedded software™ which provides information to the technician about which instrument to inspect and in what order. The proposed process could easily be integrated into the ABACUS system. This dissertation should improve both quality and productivity to address the three following points: 1) To improve quality, for which new parameters are added called instrument inspection specifications or instrument characteristics (lumen, traction surface, box lock, recess and handling time) introduced to describe what should be inspected during tray preparation (these instrument inspection specifications were assigned an ancillary number of seconds of inspection time for each specific feature of the instrument), 2) A new definition for trays is proposed based on the number of instruments and characteristics per tray (small trays are defined as having between 0 and 18 box locks, medium trays 18 to 75 box locks per tray and large trays 75 to 161 box locks) 3) To optimize manpower, Erlang-C queuing system was used as a simulation tool to describe the needs measured in number of technicians per type of tray per half hour. Further improvement to the Erlang program would be required to generate data for a full day of surgery.

Micro and small businesses in the metalworking sector present a high percentage of informality, and the majority of their production processes are not documented nor standardized. The production approach of Toyota, the enterprise-resource-planning system, and the lean manufacturing system were created for large organizations with sufficient financial resources to successfully implement these models. However, the human factor is a critical component in implementing these models. Therefore, a production management model has been proposed, which is based on lean manufacturing and focuses on the human factor, to increase productivity in the production area of a metalworking company, a small business. The result was that the company’s mentality changed, reaching a productivity of 70% through the use of lean manufacturing tools in the production area.

In the Peruvian market there is a great demand for the improvement of the service and quality of the products, that is why many SMEs look for low-cost alternatives that allow them to optimize their activities and thus be able to assure the quality of the service. The problem is that there are many difficulties when implementing tools or techniques due to high costs or lack of knowledge, therefore a productivity model is proposed focused on six sigma and lean manufacturing methodologies in order to adapt the needs of SMEs with 4 phases can analyze, design, implement and monitor requirements in order to reduce mismanagement of service quality, cost savings and decrease product returns.

Résumé :

The ability to improve employee engagement in small businesses is critical, not only to workers but also to midlevel managers who want to retain productive employees in the workplace. Supervisors who lack efficient managerial practices also risk decreases in productivity, profitability, and sustainability. The conceptual framework for this qualitative, exploratory single-case study was Kahn's theory of personal engagement and disengagement. The population consisted of 2 midlevel managers from a single, small, franchise company in metropolitan Alabama, both of whom used engagement practices, and managed at least 5 subordinates in the company. Data collected, analyzed, and triangulated were from semistructured interviews, direct observations, and a review of company documents. Coded interview responses aligned with the research question, conceptual framework, and emergent themes resulted in identifying successful engagement strategies that midlevel leaders to use. Two critical themes that emerged were management and communication. Supportive management behaviors and leader-member exchange yielded positive employee engagement and increased job performance and productivity. These results could be used to help midlevel managers develop strategies that improve employee enagagement and job performance. Social change implications included leaders developing new strategies that encourage positive relationships among top-level and midlevel leaders, lower level employees, and customers.

Résumé :

The project reported here took place in Messara plain, Crete, Greece, a semi-arid Mediterranean region. It involved a literature review (Chapter 1), a field survey (Chapter 2), two field experiments (Chapters 3 and Chapter 4) and associated laboratory analyses. The survey took place in three crop years using pairs of neighbouring organic and conventional commercial olive orchards of the cultivar Koroneiki at the valley and the surrounding hills. Both field experiments took place in a 2.4 ha table olive orchard consisted of trees of Kalamon and Manzanila olive cultivars for three crop years. Results from the field survey (Chapter 2) indicate that organic olive oil production systems developed in the Messara plain can produce the same or higher yields of oil than conventional production in the same area. Although olive oil produced from both systems is of similar quality, slightly but significantly higher levels of acidity were detected in organic olive oil. Pesticide contamination was identified as a problem in both organic and conventional production with endosulphan sulphate being the main pesticide residue. This will have to be resolved to preserve the reputation of the region for high quality oil production. Improvement in cover cropping was the main target in the 1st field experiment (Chapter 3). There were few significant effects of cover crops/cover crop mixtures on nutrient availability, invertebrate activity, and yield parameters. Rhizobium inoculation had a negative effect on Vicia sativa establishment but did not affect any of the nodulation parameters assessed. The highest levels of Hymenoptera activity were found in the cover crop mixture consisting of vetch, peas and barley. Also, the non-inoculated vetch and the cover crop mixture reduced the concentrations of olive leaf boron. The development of improved olive fruit fly management strategies was the main target in the 2nd field experiment (Chapter 4). Wind direction, humidity, rainfall and temperature were identified as important potential environmental drivers for olive fly pest pressure in the Messara region. Also, results indicate that soil survival is probably not an important over-wintering mechanism for the olive fly in the Messara plain and other semiarid Mediterranean regions. The two mass trapping systems compared differ significantly with respect to number of non-target invertebrates killed, but caught similar numbers of olive fruit flies. Results also indicated that the dates for placing mass-traps into orchard may need to be revised and related to the drivers of olive fly pressure.

The contribution of the metalworking sector to the gross domestic product is decreased by 8.6% in the 2017–2018 period because of problems such as high rejection rates, lead times, and raw material losses. Consequently, the sector’s production was reduced by PEN 1,200,000 while demand remained flat. Thus, this article proposes a production control model using 5S, Single-Minute Exchange of Dies, and tools such as Kanban and Constant Work-in-Progress (CONWIP) to increase the productivity of a sand casting line in a Peruvian metalworking enterprise that manufactures parts for mining on request. The improvement proposal involves the implementation of lean manufacturing tools and analyzes low productivity effects. The problems identified are typical of the Peruvian metalworking sector; thus, this study may contribute to finding possible solutions for issues faced by other enterprises.

Résumé :

Enterprise resource planning (ERP) systems are complex software packages that support an integrated real-time setting among the various business functions in an entire organization. ERP systems improve productivity, but only to the extent that employees accept and use the systems extensively to perform their duties. The leaders of many organizations have not been able to realize the expected benefits because of a lack of user acceptance. The purpose of this quantitative cross-sectional survey study was to examine the factors that influence user acceptance of ERP systems in the United States. Davis's technology acceptance model was the theoretical foundation used to relate the independent variables (perceived usefulness and perceived ease of use) to the dependent variable (user acceptance of ERP systems). The focus of the research questions was on the strength of the relationships between each of the independent variables and user acceptance of ERP systems in the United States. Data were from 97 purposively selected ERP system end users in the United States using the survey instrument based on the technology acceptance model. Regression and correlation analyses revealed a positive relationship between perceived usefulness and user acceptance, but no relationship was found between perceived ease of use and user acceptance. The findings indicated difficulties in using ERP systems for end users in the United States, which stakeholders could rectify to improve productivity in organizations. Positive social change implications include improving the standard of living, increasing the literacy rate, and reducing negative externalities to improve human and social conditions in society.

Résumé :

S tím, jak se neustále vyvíjejí nové technologie pro energeticky náročná průmyslová odvětví, stávající zařízení postupně zaostávají v efektivitě a produktivitě. Tvrdá konkurence na trhu a legislativa v oblasti životního prostředí nutí tato tradiční zařízení k ukončení provozu a k odstavení. Zlepšování procesu a projekty modernizace jsou zásadní v udržování provozních výkonů těchto zařízení. Současné přístupy pro zlepšování procesů jsou hlavně: integrace procesů, optimalizace procesů a intenzifikace procesů. Obecně se v těchto oblastech využívá matematické optimalizace, zkušeností řešitele a provozní heuristiky. Tyto přístupy slouží jako základ pro zlepšování procesů. Avšak, jejich výkon lze dále zlepšit pomocí moderní výpočtové inteligence. Účelem této práce je tudíž aplikace pokročilých technik umělé inteligence a strojového učení za účelem zlepšování procesů v energeticky náročných průmyslových procesech. V této práci je využit přístup, který řeší tento problém simulací průmyslových systémů a přispívá následujícím: (i)Aplikace techniky strojového učení, která zahrnuje jednorázové učení a neuro-evoluci pro modelování a optimalizaci jednotlivých jednotek na základě dat. (ii) Aplikace redukce dimenze (např. Analýza hlavních komponent, autoendkodér) pro vícekriteriální optimalizaci procesu s více jednotkami. (iii) Návrh nového nástroje pro analýzu problematických částí systému za účelem jejich odstranění (bottleneck tree analysis – BOTA). Bylo také navrženo rozšíření nástroje, které umožňuje řešit vícerozměrné problémy pomocí přístupu založeného na datech. (iv) Prokázání účinnosti simulací Monte-Carlo, neuronové sítě a rozhodovacích stromů pro rozhodování při integraci nové technologie procesu do stávajících procesů. (v) Porovnání techniky HTM (Hierarchical Temporal Memory) a duální optimalizace s několika prediktivními nástroji pro podporu managementu provozu v reálném čase. (vi) Implementace umělé neuronové sítě v rámci rozhraní pro konvenční procesní graf (P-graf). (vii) Zdůraznění budoucnosti umělé inteligence a procesního inženýrství v biosystémech prostřednictvím komerčně založeného paradigmatu multi-omics.
