Full textIn this thesis have an implementation of a maintenance program called Computerized Maintenance Management System that has been developed together with the personal from SKF. The work has been conducted for 10 weeks at Sapa Thermal Heat Transfer (Shanghai) Ltd on the maintenance department. Sapa manufacture, sell and deliver to the automobile market. The goal has been to understand and learn how to use the new computer system CMMS. It shall help Sapa to save on doing unnecessary maintenance and make it easier to order spare part, scheduled maintenance and to see the problems and the solution the problems in the CMMS database. My report is limited to parts of the CMMS. The edge guides critical points that are the position transducer and the vertical roller bearing. I describe the failures that can occur and recommend some solutions to the problems. With the creation of different concepts, explanations are given to guide you to the right solution. I give a short introduction to the current maintenance in Sapa and how to update the database through the creating of a user manual directed to Sapa. Interviews have been conducted at Sapa maintenance department with SKF and API Pro personal. The biggest helping tool has been from the CMMS there I have been able to read about current problems with the edge guide. Fact has also been taken from the Internet and material provided by Sapa The report shows a few recommendations and helping tools for how to continue the update in the CMMS for the new hot mill. Optimize the maintenance to the smallest component with the goal of saving money and production time. The reason is that CMMS shall contribute to manage the maintenance so much that the machine should have availability above 90 percent.

Full textSound maintenance strategies and planning are of crucial importance for wind power systems, and especially for offshore locations. In the last decades, an increased awareness of the impact of human living on the environment has emerged in the world. The importance of developing renewable energy is today highly recognized and energy policies have been adopted towards this development. Wind energy has been the strongest growing renewable source of energy this last decade. Wind power is now developing offshore where sites are available and benefits from strong and steady wind. However, the initial investments are larger than onshore, and operation and maintenance costs may be substantially higher due to transportation costs for maintenance and accessibility constrained by the weather.
Operational costs can be significantly reduced by optimizing decisions for maintenance strategies and maintenance planning. This is especially important for offshore wind power systems to reduce the high economic risks related to the uncertainties on the accessibility and reliability of wind turbines.
This thesis proposes decision models for cost efficient maintenance planning and maintenance strategies for wind power systems. One model is proposed on the maintenance planning of service maintenance activities. Two models investigate the benefits of condition based maintenance strategies for the drive train and for the blades of wind turbines, respectively. Moreover, a model is proposed to optimize the inspection interval for the blade. Maintenance strategies for small components are also presented with simple models for component redundancy and age replacement.
The models are tested in case studies and sensitivity analyses are performed for parameters of interests. The results show that maintenance costs can be significantly reduced through optimizing the maintenance strategies and the maintenance planning.

Full textThe wind power industry has experienced a large growth the past years. The growth mainly focus on a growing market, better economical conditions for wind power because of political decisions and the development of large wind turbines and offshore farms. A goal is to increase reliability for turbines. The topic is even more important for offshore farms where service is difficult and expensive.
The answer for the wind power industry, for better maintenance management and increased reliability, could be Condition Monitoring Systems (CMS). Such systems are commonly used in other industries. They continuously monitor the performance of the wind turbine parts e.g. generator, gearbox and transformer, and help determine the best time for a specific maintenance work. How these systems could support the wind power user is investigated in this report.
The further step could be to implement CMS as a part of Reliability Centered Maintenance (RCM).RCM is a structured approach that focus on reliability aspects when determining maintenance plans, that is to find a balance between preventive- and corrective maintenance. Preventive maintenance is maintenance carried out before failures occur and corrective maintenance is maintenance carried out after failures occur.
Condition Monitoring can consist of e.g. vibration analysis and oil analysis. In these two different analyses there are several methods that can be used. The components that are of interest of condition monitoring are the gearbox, generator and the main shaft. The component of most interest, and that it has been shown is a critical component due to its impact on system availability, is the gearbox.
Life Cycle Cost (LCC) analyses have been made to calculate if it is profitable to implement CMS. The total cost, LCC including additional costs for implementing CMS, is compared for different alternative maintenance strategies. For a single turbine onshore versus an average turbine offshore in three strategies, and for a farm offshore where maintenance is planned using CMS in three strategies. The LCC without costs for CMS is called the basic case.
The first three strategies studied for the separate turbine onshore gave the following results when a CMS cost is added to the basic case; to compensate for the additional cost the preventive maintenance has to be decreased by 23 %. To compensate for the additional cost the preventive and corrective maintenance together have to be decreased by 3,5 %. The same results for the farm offshore, where an average turbine was observed, were 4,5 % and 2,5 % respectively. Decreased corrective maintenance is needed to motivate CMS, at least for the turbine onshore.
The following three strategies studied for the farm offshore gave the following results: a change from corrective maintenance to preventive maintenance with 47 % would be enough to make CMS profitable. The availability would not have to be increased with more than 0,43 % to get a reduction in cost for production loss that would cover the cost for CMS.

The United States Coast Guard (USCG) has entered a unique period in its history marked by the aging of its legacy cutter fleet, the construction and integration of replacement cutters, tight fiscal constraints and the recent modernization of its logistics support organization. The achievement of maritime missions is dependent on the proper allocation of agency resources across the operation, maintenance and repair of Coast Guard cutters. Interdependencies caused by the shared resources of time, funding and inventory parts create complex interactions between the components that make up the Coast Guard's cutter operations and maintenance system. This thesis uses System Dynamics modeling and simulation techniques to analyze the Coast Guard's cutter operations and maintenance system to identify system constraints, evaluate policy and resource alternatives, and recommend policy changes to improve the operational availability of the fleet. The application of System Dynamics modeling and simulation tools identify several high leverage variables in the operations and maintenance system structure. Small changes to these variables capitalize on the reinforcing feedback mechanisms already present in the system structure to produce significant improvements in the operational availability of the fleet. Maintenance and repair part inventory levels and operational policies governing cutter standby status are identified as key drivers of system performance, and specific recommendations are provided to increase operational patrol hours by up to 15% and decrease cutter casualty hours by up to 25%. Other recommendations include the revision of command performance metrics to drive behaviors that influence these high leverage variables, application of System Dynamics principles to new cutter sustainment strategies, and expansion of the use of real-time operations and engineering data in engineering and scheduling policy decisions.

Full textKapitalförvaltning har inom alla områdem blivit allt viktigare, speciellt inomelkraftsteknik. Det beror i huvudsak av två orsaker. Den första är storinvesteringskostnad, vilket inkluderar design, konstruktion, utrustning och underhåll.Den andra är den höga straffavgiften för system operatören vid elavbrott. Dessutom,på grund av den nyligen avreglerade elmarknaden, så fäster elföretagen meruppmärksamhet på investerings och underhållskostnader. En av deras huvudmål är attmaximera underhållsprestandan. Så utmaningen för operatörerna är att levereratillförlitlig elkraft till kunder, samtidigt vara kostnadseffektiva mot leveratörer.Reliability Centered Asset Management (RCAM) är bland de bästa metoderna för attlösa detta problem. En enklare RCAM metod är introducerad först i denna rapport.Modellen inkluderar en underhållsstrategi-definition, underhållskostnad-kalkyl och enIIoptimiserings modell. Grundad på denna enklare modell, andra förbättringar ärtillagda och en ny modell är föreslagen. Förbättringarna inrymmer en nyunderhållsstrategi, ökad felfrekvens och en ny målfunktion. Den nya modellentillhandahåller också en tidsbaserad underhållsplan.

Full textFor complex technical systems in the electricity and pulp and paper industries, maintenance management addresses how to exploit physical assets in the most profitably way. This is a difficult task that requires taking into consideration parameters of totally different natures – e.g. reliability data, operating costs, condition of technical systems, the environment and rules and regulation.
An incorrect estimate of a residual lifetime can result in a premature renewal with accompanying high capital costs. If, however, renewal is delayed, a breakdown may occur which can cause major damage to technical equipment and a loss of income due to outages. Because of the complexity of many technical systems, it can be hard to select adequate data to use when making decisions about renewal strategies. To cope with this, one approach is to use less detailed models that are operated by skilled analysts.
This work demonstrates the advantage of such an approach by proposing two methods applied in a joint methodology that has its origins in RCM. The methodology consists of Dynamic Lifetime Model (DLA) and the Condition Based Index (CBI). The DLA method copes with the financial risk associated with the point in time for when a renewal is carried out and the CBI method uses critical parameters to estimate the condition of a technical system. The two methods together create a quantitative connection between reliability, maintenance and financial risk. A case study based validation of the methodology was carried out at SCA Ortvikens paper mill on a refiner system and Forsmark nuclear power plant. Lessons learned from the case study showed that the methodology could be used to identify which components could cause costly breakdown. By using the methodology a manager gets a decision support tool for estimating short-term and long-term consequences of decisions regarding maintenance management in order to maximize utility of the system concerned

Infrastructure includes systems including buildings, roads, water/wastewater, trash, and various other networks that facilitate citizens everyday lives. These infrastructure systems will always require maintenance in order to keep it running effectively and efficiently. Using smart and sustainable practices in this process can help better meet user needs, while saving more money. Using more technology such as 311-call centers can allow cities to detect and more quickly respond to real-time infrastructure disruptions and maintenance issues. 311 call centers receive calls about anything from street condition problems such as potholes to problems with their drinking water. Of the 200 or more cities that use 311, New York City’s system is the largest, receiving more than 20 million citizen requests since 2010. The first manuscript looks into what certain types of people call about. Using zip codes, areas of the city were grouped together based on four socio-economic variables; median house value, percent of the population with a bachelor’s degree, unemployment rate, and percent non-white. People from low socio-economic areas, meaning those with low median house values, low population with a bachelor’s degree, high unemployment, and high percent non-white call more about infrastructure maintenance requests. When controlling for physical aspects of these areas such as miles of road, total amount of calls, and the number of people per zip code, people from low socio-economic areas are more likely to call about issues related to street conditions, sanitation, and their water system. The second manuscript looks into how long it takes government agencies to respond and resolve these calls. The location of the call based on location in the city and the socio-economic characteristics of the zip codes have an effect on agency response time. People reporting issues in Queens can expect to wait much longer, about 3 days more, to receive a response for a similar issue called from another borough of New York City. The Department of Transportation, Department of Sanitation, and the New York Police Department respond significantly faster to service requests in areas with high and middle socio-economic status groups compared to zip codes with low socio-economic groups of people. By knowing that location and socio-economic status matter when citizens call 311, city engineers can begin to use this data to help prioritize maintenance issues based on specific areas and needs of individual people in the future. These differences in location and socio-economic characteristics could possibly suggest unequal treatment of maintenance issues. However, since the differences seen in this research are with only certain variables accounted for, further research will be needed to help show possible causation for these differences.

El desenvolupament d'aquesta tesi doctoral s'emmarca dins d'un acord de cotutela entre la Università degli Studi di Palermo (UNIPA) i la Universitat Politècnica de València (UPV), dins dels seus respectius programes de doctorat en 'Enginyeria d'Innovació Tecnològica' i ' Matemàtiques '. Aquests programes estan estretament vinculats a través del tòpic MCDM, ja que proporciona eines crucials per gestionar el manteniment de sistemes complexos reals utilitzant anàlisis matemàtics profunds. El propòsit d'aquesta sinergia és tenir en compte de forma sòlida la incertesa en atribuir avaluacions subjectius, recopilar i sintetitzar judicis atribuïts per diversos responsables de la presa de decisions, i tractar amb conjunts grans d'aquests elements en els problemes plantejats. El tema principal del present treball de doctorat es la gestió de les activitats de manteniment per augmentar els nivells d'innovació tecnològica i el rendiment dels sistemes complexos. Qualsevol sistema pot ser considerat objecte d'estudi, inclosos els sistemes de producció i els de prestació de serveis, entre d'altres, mitjançant l'avaluació dels seus contextos reals. Aquesta tesi doctoral proposa afrontar la gestió del manteniment mitjançant el desenvolupament de tres línies principals d'investigació estretament vinculades. ¿ La primera és el nucli, i il·lustra la majoria dels aspectes metodològics de la tesi. Es refereix a l'ús de mètodes MCDM per donar suport a decisions estratègiques de manteniment, i per fer front a la incertesa que afecta les dades/avaluacions, fins i tot quan estan involucrats diversos responsables (experts en manteniment) en la presa de decisions. ¿ La segona línia desenvolupa anàlisis de fiabilitat per a sistemes complexos reals (també en termes de fiabilitat humana) sobre la qual base s'ha d'implementar qualsevol activitat de manteniment. Aquestes anàlisis consideren la configuració de fiabilitat dels components del sistema en estudi i les característiques específiques de l'entorn operatiu. ¿ La tercera línia d'investigació aborda aspectes metodològics importants de la gestió de manteniment i emfatitza la necessitat de monitoritzar el funcionament de les activitats de manteniment i d'avaluar la seva efectivitat utilitzant indicadors adequats. S'ha elaborat una àmplia gamma de casos d'estudi del món real per avaluar l'eficàcia dels mètodes MCDM en el manteniment i així provar la utilitat de l'enfocament proposat.
[EN] This doctoral thesis proposes using multi-criteria decision making (MCDM) methods as a strategic tool to support maintenance management of complex systems. The development of this doctoral thesis is framed within a cotutelle (co-tutoring) agreement between the Università degli Studi di Palermo (UNIPA) and the Universitat Politècnica de València (UPV), within their respective programmes of doctorates in 'Technological Innovation Engineering' and 'Mathematics'. Regarding this thesis, these programmes are closely linked through the topic of MCDM, providing crucial tools to manage maintenance of real complex systems by applying in-depth mathematical analyses. The purpose of this connection is to robustly take into account uncertainty in attributing subjective evaluations, collecting and synthetizing judgments attributed by various decision makers, and dealing with large sets of elements characterising the faced issue. The main topic of the present doctoral work is the management of maintenance activities to increase the levels of technological innovation and performance of the analysed complex systems. All kinds of systems can be considered as objects of study, including production systems and service delivery systems, among others, by evaluating their real contexts. Thus, this doctoral thesis proposes facing maintenance management through the development of three tightly linked main research lines. ¿ The first is the core and illustrates most of the methodological aspects of the thesis. It refers to the use of MCDM methods for supporting strategic maintenance decisions, and dealing with uncertainty affecting data/evaluations even when several decision makers are involved (experts in maintenance). ¿ The second line develops reliability analyses for real complex systems (also in terms of human reliability analysis) on the basis of which any maintenance activity must be implemented. These analyses are approached by considering the reliability configuration of both the components belonging to the system under study and the specific features of the operational environment. ¿ The third research line focuses on important methodological aspects to support maintenance management, and emphasises the need to monitor the performance of maintenance activities and evaluate their effectiveness using suitable indicators. A wide range of real real-world case studies has been faced to evaluate the effectiveness of MCDM methods in maintenance and then prove the usefulness of the proposed approach.

Full textTraditional corrective maintenance is both costly and ineffective. In some situations it is more cost effective to replace a device than to maintain it; however it is far more likely that the cost of the device far outweighs the cost of performing routine maintenance. These device related costs coupled with the profit loss due to reduced production levels, makes this reactive maintenance approach unacceptably inefficient in many situations. Blind predictive maintenance without considering the actual physical state of the hardware is an improvement, but is still far from ideal. Simply maintaining devices on a schedule without taking into account the operational hours and workload can be a costly mistake. The inefficiencies associated with these approaches have contributed to the development of proactive maintenance strategies. These approaches take the device health state into account. For this reason, proactive maintenance strategies are inherently more efficient compared to the aforementioned traditional approaches. Predicting the health degradation of devices allows for easier anticipation of the required maintenance resources and costs. Maintenance can also be scheduled to accommodate production needs. This work represents the design and simulation of an intelligent maintenance management system that incorporates device health prognosis with maintenance schedule generation. The simulation scenario provided prognostic data to be used to schedule devices for maintenance. A production rule engine was provided with a feasible starting schedule. This schedule was then improved and the process was determined by adhering to a set of criteria. Benchmarks were conducted to show the benefit of optimising the starting schedule and the results were presented as proof. Improving on existing maintenance approaches will result in several benefits for an organisation. Eliminating the need to address unexpected failures or perform maintenance prematurely will ensure that the relevant resources are available when they are required. This will in turn reduce the expenditure related to wasted maintenance resources without compromising the health of devices or systems in the organisation.

Outsourcing maintenance to third-party contractors has become an increasingly popular option for manufacturers to achieve tactical and/or strategic objectives. Though simple in concept, maintenance outsourcing is difficult in execution, especially in a cost-sensitive environment. This project examines the Full Service business under ABB Ltd to understand the key factors that drive the success of an outsourced maintenance operation. We present a qualitative causal loop diagram developed based on the case study of Kinleith Pulp and Paper Mill in New Zealand. The diagram describes the interconnections among various technical, economic, relationship, and humanistic factors and shows how cost-cutting initiatives can frequently undermine labor relationship and tip the plant into the vicious cycle of reactive, expensive work practices. The model also explains how Kinleith achieved a remarkable turnaround under ABB, yielding high performance and significant improvements in labor relations. A case study of Tasman Pulp and Paper Mill provides a contrasting case where success has been more difficult. Results point to the importance of creating sufficient resources ("slack") to implement improvement activities and pace implementation based on pre-existing dynamics on site.

This thesis addresses the allocation of gas turbine aircraft engines to maintenance facilities. Scheduling a global engine maintenance network can be very complex and challenging. This project pertains particularly to the V2500 IAE engine maintenance network managed by Pratt & Whitney. Using a mathematical program to automate engine allocation was believed to reduce the workload on the organization and the cost of maintaining the 3100 engine fleet. An introduction to the engine maintenance network will be covered along with an explanation of Fleet Hour Agreements (FHA). A literature review of mathematical programming is included to provide background of pertinent information. The current state of the business is analyzed. An integer linear program is developed to closely represent the current state of the business. Historical data was used to feed the model, and the outputs from the model were compared to actuals. A sensitivity analysis is performed to better understand the constraints of the current business and the feasibility of the model. An optimization model should not be used to plan engine maintenance given the current state of business. The business is too dynamic and the network is highly constrained by capacity. The results also show a much smaller savings than were originally expected. This is mostly due to better understanding the cost of maintaining the engines at the different shops. The variation was much lower than originally expected. The current state is operating close to optimal with great flexibility and should continue on as is.

Drug Discovery is a race to be the first to patent a drug that meets a significant medical need in the world. Many pharmaceutical companies are now using automation extensively to improve consistency and aid personnel in testing the millions of potential drug candidates within their labs. Because these machines play an important role in drug discovery, there is significant interest in managing their maintenance. The concern is that downtime is hampering the efforts of drug discovery. This project has sought to reduce that downtime and manage maintenance costs by working with the Technical Operations Group, Novartis' in-house maintenance team. The main objectives have been to devise a better way for evaluating maintenance contracts, improve the availability of the equipment, and instill a culture of continuous improvement in the group. This study shows that maximizing equipment utilization should be a higher priority than reducing downtime. The data show that the high throughput systems are only used an average of three days a week. Reducing downtime, which is most often measured on the scale of minutes, is unlikely to bring about the gains that would be realized by improving capacity utilization. Current metrics and data collection procedures are ineffective for determining automation needs and performance as well as engineer performance. A new system for data collection was implemented along with improvement projects as an introduction to lean principles, with the primary objective being a self-sustaining system of finding process improvements.
(cont.) Contracts were evaluated along four criteria: the indispensability of the equipment under contract, the adjusted replacement cost, the level of customization, and the age of equipment. The end results of the internships include a metric gathering system that more closely monitors engineer activity as opposed to equipment activity, completed improvement projects such as the complete overhaul of the tool room including inventory management as well as an automated error log system, and a way of evaluating contracts that will reduce costs without sacrificing performance.

Full textThis thesis outlines guidelines for the implementation of a preventive maintenance policy. Preventive maintenance treatments currently being used within Virginia include chip seal, slurry seal, microsurfacing, and thin hot mix asphalt overlays. Historical pavement condition data was obtained from the VDOT PMS for these treatments and treatment performance models were developed. A district level treatment selection tool was developed to assist the district level decision making process. A prioritized list of pavement sections was generated, maximizing the cost-effectiveness of the selected treatments subject to budgetary constraints set by the central office.
The treatment selection tool was then run for each pavement classification in each district. The results of this analysis were presented. Although the recommended budget for each district was very close to the targets set by the central office, the recommended lane miles for each district were about half the targets set by the central office. It is believed that the unit costs used in this analysis were higher than those used in the VDOT PMS analysis. This selection tool has the potential to be a very powerful decision support tool if the unit costs are representative of what the expected treatment costs are for each district.

Quest Diagnostics has committed to reducing operating expenses by $1.3B between 2012 and 2017. A portion of the cost-saving initiative focuses on reagents - expensive liquids that are combined with patient samples to detect compounds of interest. This project aims to reduce reagent waste for high-volume diagnostic tests run on an instrument platform that generates a relatively high amount of reagent waste. Waste, in this context, means any reagent that does not generate unique patient results. Therefore critical components of the quality system, such as quality control and calibration tests, are designated waste even though they are a necessary expenditure. Quality control (QC) samples and mechanical errors accounted for 5.2% and 4.4%, respectively, of all reagent usage prior to the start of the project. Mechanical errors occur when the diagnostic testing platform encounters something unexpected, such as debris or a reading that indicates insufficient sample volume, which interrupts sample processing. The instrument jettisons this test and attempts to repeat the assay. Initial discussions with laboratory representatives revealed differing interpretations of quality control requirements. All sites using the platform of interest were then surveyed to gauge the extent of variation. All sites met quality control requirements but several exceeded them. The most pertinent variations are listed below. 1. Frequency: Several sites ran control samples more often than established in Standard Operating Procedure (SOP) requirements, increasing total QC usage by over 70%. 2. Container size: The choice of container determines the amount of "dead volume", material that the instrument cannot access and must be discarded. Some sites used containers with 12.8 times the dead volume required in the smallest option. 3. Reuse policy: Some labs reuse containers of quality control materials across multiple batches. Reusing QC material further reduces the amount of dead volume discarded, but using new QC materials eliminates the possibility of evaporation between batches. An interdisciplinary team of experts tasked with maintaining the SOPs has reviewed these results and will clarify the appropriate SOP interpretation to unify practices across laboratories. In order to understand mechanical errors, I observed routine maintenance at four sites and found that business units did not consistently share best practices. Collaborating with vendor representatives and operators, I launched an Autonomous Maintenance (AM) pilot program in order to develop training materials capturing institutional knowledge and to test additional maintenance procedures. The AM activities generated 29 training documents, which were added to a national database of competency training materials. All operators certified to operate the testing platform will be required to review and pass comprehension quizzes on the training materials. As the Marlborough site continues to develop improvements to the maintenance procedures, these changes will be shared with the vendor and incorporated into training documents.

Full textDigitalisering har påverkat och transformerat företag över hela världen genom att erbjuda nya värdeproducerande möjligheter. För att bibehålla konkurrenskraft i en föränderlig omvärld måste järnvägsoperatörer transformera sina företag och förvärva nya digitala lösningar och verktyg kopplade till järnvägsteknologier. Genom att digitalisera informationsintensiva processer med hjälp av informationssystem, blir det möjligt för järnvägsföretag att minska förlust av drifttid samt minska den totala underhållskostnaden. Samtidigt har den begränsade forskningen gällande användning av informationssystem i underhållsorganisationer försvårat digitaliseringsförsöken. Litteratur och tidigare studier har behandlat de två ämnena separat, dock har överlappande forskning varit otillräcklig. Denna studie syftar till att bidra med kunskap för att överbrygga gapet i litteraturen genom att undersöka de vinningar en underhållsorganisation kan erhålla med hjälp av ett informationssystem och de framgångsfaktorer som krävs för att uppnå dem. Genom att utföra denna studie i samarbete med det svenska underhållsbolaget MTR Tech AB har de potentiella användningsområdena av ett informationssystem identifierats. De tre huvudsakliga affärsmöjligheterna som kan erhållas från ett informationssystem är: stödjande av felsökningsprocessen, bättre planering av avhjälpande underhåll, samt möjliggörandet av tillståndsbaserat underhåll. Samtidigt har det visat sig att lönsamheten av ett informationssystem är direkt kopplat till dess utnyttjandegrad. Vi har således dragit slutsatsen att den affärsmöjlighet som bör eftersträvas är den som med största sannolikhet kommer att genomföras framgångsrikt under rådande omständigheter. Slutligen visar våra resultat att de framgångsfaktorer som krävs för att uppnå affärsmöjligheterna är en dedikerad projektgrupp, tydlig kommunikation och informationsdelning, samt lämplig personal.
