In the era of national transformation and regional autonomy, there have been many breakthroughs in the management of land fixed assets, but many financial problems and land assets have not been implemented optimally, effectively and efficiently in their management. This study was used to analyze the effect of asset management on the optimization of fixed land assets in Malang Regency Government. The independent variables used in this study were asset inventory, asset use, asset security, and maintenance, while the dependent variable used asset utilization and asset optimization with a sample of 62 respondents. This type of research is quantitative using multiple regression analysis and path analysis method. The results showed that there was an indirect effect of asset inventory, asset use, and asset security and maintenance on asset optimization through asset utilization where security and asset maintenance had a significant and positive effect, while asset inventory and asset use had no effect on asset optimization. The direct effect of asset inventory, asset use, asset security, and maintenance on asset optimization shows that asset inventory and asset security have a significant and positive effect on asset optimization, while asset use has no effect on asset optimization. In addition, asset utilization has a significant and positive effect on asset optimization.

Full textAbstract:
Roads and water pipe assets undergo various deterioration processes due to the high demand for their services. Maintenance of these assets is often planned as individual assets, and the interdependency among different assets is neglected. An integrated framework for cross-asset maintenance is required for optimum utilization of the available funds for asset maintenance. To date, there are very few studies focusing on the use of the analytical hierarchy process (AHP) for cross-asset maintenance of roads and water pipe assets. Therefore, this research aims to develop an integrated fund allocation model for the maintenance of road and water pipe assets. A model was developed using AHP analysis based on expert opinions captured through a questionnaire in order to obtain optimum maintenance fund allocation for the cross-assets, roads, and water pipes. Then, a case study corridor segment with the considered cross-assets was selected, and a trade-off analysis was conducted for the intervention alternatives considering different levels of service (LOS) of the asset elements. The results of the trade-off analysis can be used to identify the optimum intervention alternative that satisfies the budget requirement and results in the maximum benefit. Overall, asset managers can use the approach presented in the present study to develop a cross-asset fund allocation model when multiple assets are involved in maintenance.

Asset management is a method that transferred the assets into cost to management. The main object is that to calculate the value of assets and assess the benefit of investment. When utilized the asset management method on freeway pavement management, it must been founded on assets inventory and historic maintenance. To calculate all the cost of assets could list the value of all the assets. The most important work of asset management was assessing the assets. All the assets were analyzed the survival life of all the assets and find out period of the depreciation in the study. It is 8.9 years that the period between newly construction and first maintenance. It is 4.5 years that the period between maintenances. The assess model was set by the two periods. The results cross by the assess model was that the assets service level was great.

Abstract In the case of a high-valuable asset, the Operation and Maintenance (O&M) phase requires heavy charges and more efforts than the installation (construction) phase, because it has long usage life and any accident of an asset during this period causes catastrophic damage to an industry. Recently, with the advent of emerging Information Communication Technologies (ICTs), we can get the visibility of asset status information during its usage period. It gives us new challenging issues for improving the efficiency of asset operations. One issue is to implement the Condition-Based Maintenance (CBM) approach that makes a diagnosis of the asset status based on wire or wireless monitored data, predicts the assets abnormality, and executes suitable maintenance actions such as repair and replacement before serious problems happen. In this study, we have addressed several aspects of CBM approach: definition, related international standards, procedure, and techniques with the introduction of some relevant case studies that we have carried out.

An organization or company certainly has assets to support its operational activities, so it is very important to maintain the assets themselves. Not maintaining assets and asset data can be an important problem for the organization or company. This asset maintenance system aims to facilitate the maintenance of asset data, especially at the Jambi Class III Port Health Office. The Jambi Class III Health Office is a Technical Implementation Unit within the Ministry of Health which is under and responsible to the Directorate General of Disease Prevention and Control. Asset maintenance in the office still uses the manual method, namely the person in charge of the room comes directly to make a request for repairs, making it difficult for officers to maintain these assets. To overcome this problem, we need a form of asset maintenance system that can assist in the repair request process. Making this application is done by collecting data, system planning, system analysis, system design and database. The database used is MySQL. The input requirements for the Information Technology Equipment Asset Maintenance System are asset data, room data, and work area data. The process requirements needed are: Login process, request process, and input, update, and delete processes. The output data produced is in the form of information that will be attached, including: the request report is approved, and the request data report is rejected. The purpose of making this thesis is the creation of a Web-Based Information Technology Device Asset Maintenance System. With the existence of a new system that has been designed and created by researchers, it can help facilitate the parties involved in maintaining information technology equipment assets.

Asset management involves the coordinated activities of an organisation to derive value from assets, which may include physical assets. It encompasses activities related to design, construction, installation, operation, maintenance, renewal, and asset disposal. Asset management ensures the coordination of all activities, resources, and data related to physical assets. Recording and monitoring all maintenance activities is a key part of asset management, often done using work orders (WOs). Technicians typically create WOs using “free text”, which can result in missing or ungrammatical words, making it difficult to identify trends and analyse information. To standardise the terminology used for the same asset maintenance operation, this paper proposes a method that suggests words to technicians as they complete WOs. The word suggestion algorithm is based on past maintenance records, and a Bayesian network-based recommender system adapts to present needs verified by technicians using implicit user feedback. Implementing this system aims to normalise the terms used by technicians when filling in a WO. The corpus for this work comes from asset management records collected in a health facility in Portugal operated by a private company.

Galuh University is a private university that has 7 faculties, 1 Postgraduate Program, Institute for Research and Community Service (LPPM), Internal Quality Assurance Agency (BPMI), Libraries and Cooperation Offices. Of the many places in Galuh University, it becomes a problem that must be faced in asset management. The management of these assets still relies on the role of humans who cannot collect a lot of asset data. If the person forgets it will be a problem especially regarding the type of asset that makes the payment and if it is late, it will be subject to sanctions or fines. This research is to make it easier to calculate the number of assets and record the maintenance of these assets. This asset management application will be web-based using the PHP programming language and MySQL as the database. The results of this study are in the form of a database design which will later be implemented on a website that can be accessed by asset managers who will record asset maintenance and also as a reminder of asset maintenance at Galuh University

Enterprise asset management (EAM) systems are used by asset owners and/or operators to manage the maintenance of their physical assets. These assets, including equipment, facilities, vehicles, and infrastructure, need maintenance to sustain their operations. An EAM system provides the means to have less unplanned downtime and extended asset longevity, which offers clear business benefits that improve the profit and loss statement and balance sheet. Particularly for capital-intensive industries, like drilling and exploration, the failure of on-time delivery of critical equipment or processes is disruptive and costs nonproductive time and customer satisfaction. Organizations understand these issues and employ an appropriate asset management system to engineer their asset maintenance and management. An EAM system is needed to manage the people, assets/equipment, and processes. EAMs are used to plan, optimize, execute, and track the needed maintenance activities with associated priorities, skills, materials, tools, and information. Similarly, nondestructive testing (NDT) is used as a tool for integrity assessment of assets in drilling and exploration. The main advantage of using NDT is that the item’s intended use or serviceability is not affected. The selection of a specific technique should be based on knowledge and skills that include design, material processing, and material evaluation. Validating the purpose of this paper, we emphasize the importance of optimizing the asset utilization and serviceability to enhance overall efficiency by integrating EAM software that manages assets, the operation management system (OMS) controlling the processes, and asset inspection management systems (AIMSs).

ENGLISH ABSTRACT: A critical success factor for investment in high capital intensive business is to ensure that there is an integrated physical asset management plan in place that is integrated with the business strategy. The three fundamental aspects in modern physical asset management are to have a balanced performance measurement framework, self assessment system and benchmark review process in place to integrate, control and continuously improve the return on asset investment. There is a general lack of "hands-on" structured integration and performance management in the physical asset management environment. The result is ineffective assets with high life cycle costs that will have a negative effect on the business return on investment. A literature study was done on the most resent physical asset management models and business performance measurement systems to identify if the necessary methods and business systems exist to effectively manage the physical asset management function. A self assessment review and benchmark was done on Ticor South Africa and Kumba Resources centres to identify the gap in performance and what the main criteria is for improvement. The process was also used to identify the barriers that exist to effectively implement and integrate physical asset management with a link into business strategy. Achieving success in any strategy implementation requires a team effort among all stakeholders. A shared understanding and collaboration of all the role players is required. Very often physical asset management is not seen as core business, but as a cost centre that cannot be done without. This leads to sub optimisation and increased asset life cycle cost. It also promotes the tendency to make short-term financial decisions that do not have any longterm sustainability. A further downside to it is that if the function is seen as a service department it will only be reactive to business strategy and does not form part of the business strategy. This leads to a very reactive situation where the actions are driven by fixing what is wrong just to stay in business. A uniform performance measurement framework must be implemented across all business functions to align the entire organisation with the business goals. All functions have an effect on overall business performance, but they seldom have conflicting goals. Physical asset managers are sometimes not properly prepared and skilled to ensure that an effective and efficient physical asset management function is being maintained. Training and learning should be a major focus to ensure optimum use of employee potential in meeting the functional goals. Ignored leadership is a recipe for poor performance and frustration. The degree to which a company's business functions and processes are aligned with customers' needs makes a significant impact on the bottom line. The key objectives for the physical asset management strategy should be drafted with customer "needs and wants" in mind. The objective must be to maximise long-term profitability of plant and equipment through utilisation of the allocated resources. The opportunities and improvement methods that are possible in the physical asset management environment are endless and the potential that exists can be missed by the likelihood of failure to implement it effectively. The lack of managerial support is in many cases the only cause of failure to link physical asset management with business strategy. Secondly, the weakness of some of the solutions offered and the lack of embedding the solutions that are generated also contribute to the failure of linking physical asset management with business strategy.

AFRIKAANSE OPSOMMING: 'n Kritiese faktor vir die suksesvolle belegging in kapitaal intensiewe besighede is om te verseker dat 'n geïntegreerde fisiese batebestuurplan in plek is wat met die besigheidstrategie integreer. Die drie fundamentele aspekte in moderne fisiese batebestuur is om 'n gebalanseerde prestasieraamwerk vir bestuur, self-evalueringstelsel en doelwit-bestuursproses in plek te hê, om dit te integreer, te beheer en deurlopend opbrengste op bate-belegging te verbeter. Daar is 'n algemene gebrek aan vaardighede om die gestruktureerde integrasie en prestasiebestuur in die fisiese batebestuursomgewing te verseker. Die resultaat is oneffektiewe bates met baie hoë lewensikluskoste wat die besigheid se opbrengs op kapitaal negatief sal beinvloed. 'n Literatuurstudie is gedoen om die nuutste fisiese batebestuurmodelle en prestasiebestuurstelsels te identifiseer en te analiseer. Die doel was om vas te stel of die nodige metodes en besigheidraamwerke bestaan waarmee die fisiese batebestuur funksie bestuur kan word. 'n Self-evaluering analise en doelwitmeting is gedoen op Ticor South Africa en Kumba Resources-sentra met die doel om die gapings in prestasie te identifiseer en kriteria vir verbetering te bepaal. In die proses is die hindernisse wat in die pad van effektiewe implementering en integrering van fisiese batebestuur met besigheidstrategie staan, geïdentifiseer. Spanwerk word benodig vir die suksesvolle implementering van besigheidstrategie. 'n Gedeelde verstandhouding en samewerking deur alle belanghebbendes word benodig. Fisiese batebestuur word gereeld uitgesonder as een van die nie-kern besigheidsfunksies en dat dit slegs 'n kostesentrum is waarmee nie weggedoen kan word nie. Dit lei tot die suboptimisering van die bate se lewensiklus-koste. Dit skep ook die tendens om slegs korttermyn finansiële besluite te neem, wat geen langtermyn volhoubaarheid het nie. 'n Verdere gevolg is dat die funksie slegs beskou kan word as 'n dienste-funksie en dat dit baie reaktief raak teenoor strategie verandering. Die funksie word ook nie deel van die besigheidstrategie nie. Dit lei tot 'n baie reaktiewe situasie waarin aksies en inisiatiewe slegs gedryf word deur die noodsaaklikste bates te herstel net om in besigheid te bly. 'n Uniforme prestasie-bestuursraamwerk moet geïmplementeer word regoor al die besigheidsfunksies om die totale organisasie se besigheidsdoelwitte in ooreenstemming te bring. Al die besigheidfunksies het 'n effek op oorhoofse besigheidprestasie, maar daar is baie selde doelwitte wat totaal in konflik met mekaar is. Fisiese batebestuurders is soms nie ten volle voorbereid of bevoeg om te verseker dat 'n effektiewe fisiese batebestuursfunksie onderhou word nie. Opleiding en mentorskap moet 'n fokuspunt wees om te verseker dat werknemerpotensiaal benut word in die bereiking van funksionele doelwitte. Leierskap wat agterweë bly is 'n resep vir lae prestasie en frustrasie. Die graad waartoe 'n besigheidfunksie en proses ooreenstem met sy kliente se behoeftes sal 'n beduidende impak op die netto prestasie van die besigheid hê. Die kern doelwitte van die fisiese batebestuurstrategie moet opgestel word deur die behoeftes van die kliente in ag te neem. Langtermyn winsgewendheid van aanlegtoerusting moet die doelwit wees tydens die allokasie van hulpbronne. Die geleenthede en verbeteringsmetodes beskikbaar in die fisiese batebestuuromgewing het oneindige potensiaal wat verlore kan gaan as nagelaat word om die funksie effektief te implementeer. Gebrek aan ondersteuning deur bestuur is in baie gevalle die rede hoekom die fisiese batebestuurfunksie nie geïntegreer is met die besigheidstrategie nie. Die swakpunte van sommige van die oplossings wat aangebied word en die onvermoë om oplossings te implementeer, dra by tot die mislukking om fisiese batebestuur met besigheidstrategie te verbind.

Thesis (MEng)-- Stellenbosch University, 2013.ENGLISH ABSTRACT: Asset Management initiatives suffer many barriers in implementation which hinder their influence and sustainability. One of these barriers is the lack of buy-in from all levels in the organisation, due to a lack of understanding of the perceived benefits of Asset Management. The relationship between throughput and the maturity of Asset Management implementation is usually felt throughout the organisation, but is difficult to prove or quantify. Furthermore, it is di cult to isolate the effects of maintenance using traditional methods. Organisational alignment in an Asset Management project is achieved by aligning employees' views on what the deficient areas in the organisation are, and managing their expectations in what the perceived benefit of a good application of Asset Management would bring forth. However, the lack of a transparent method to convey the significance of critical areas in the system, and a clear way to communicate these problems creates a barrier in implementation. Without empirical evidence people rely on argumentative opinions to uncover problems, which tends to create friction as opinions from various factions may differ. Typically, these initiatives are constrained by available resources, and the allocation of resources to the correct areas is thus vital. In order for Asset Management initiatives to be successful there first needs to be alignment in execution through a clear understanding of which assets are critical, so that resources can be allocated effectively. In this study, this problem is thoroughly examined and solutions are sought in literature. A method is sought which seeks to isolate the effects of the maintenance function in an operation and uncover critical areas. A study is performed on methods which are typically used to create such understanding, which are shown to have shortcomings that limit their applicability. Thus a new methodology utilising simulation is created in order to overcome these problems. The methodology is validated through a case study, where it is shown that the simulation, in the context of the methodology, is highly beneficial to uncovering critical areas and achieving organisational alignment through communication of results.
AFRIKAANSE OPSOMMING: Fisiese bate bestuursinitiatiewe het verskeie tekortkominge in hulle implementering wat hulle invloed en volhoubaarheid verhinder. Een van hierdie hindernisse is die tekort aan ondersteuning van alle vlakke in die organisasie, wat as gevolg van 'n gebrek aan begrip van die voordele van bate bestuur voorkom. Die verhouding tussen die volwassenheid van batebestuur en produksie deurset word gewoonlik reg deur die organisasie gevoel, maar hierdie verhouding is moeilik om te bewys of te kwantifiseer. Verder is dit moeilik om met huidige methodes die gevolge van instandhouding te isoleer, en dus deeglik te begryp. Organisatoriese aanpassing by `n bate bestuursprojek word bereik deur werknemers se siening te belyn oor wat die gebrekkige areas is, en om hulle verwagtinge te bestuur oor die voordele wat `n goeie bate bestuursprojek kan voortbring. Daar is `n gebrek aan metodes om in `n deursigtige wyse die kritieke areas aan te dui en te komunikeer aan werknemers. Dit skep `n hindernis in die uitvoer van projekte en, in die afwesigheid van empiriese bewyse van probleme, is werknemers afhanklik van argumentatiewe menings om probleme te ontbloot, en die menings van verskeie rolspelers kan verskil. Enige inisiatiewe is tipies beperk deur die beskikbaarheid van hulpbronne daarvoor, en `n effektiewe toedeling van beskikbare hulpbronne is dus noodsaaklik. Om `n suksesvolle batebestuursprojek uit te voer, moet daar eers `n duidelike begrip en ooreenstemming wees oor wat die verskeie kritieke areas is wat die meeste aandag verlang, sodat hulpbronne doeltreffend toegeken kan word. In die studie word hierdie probleem deeglik ondersoek deur oplossings na te vors in die literatuur. `n Metode is gesoek wat daarop gemik is om die gevolge van instandhouding te isoleer in `n produksiestelsel en kritiese areas te ontbloot. `n Studie is uitgevoer op metodes wat gewoonlik gebruik word om sodanige analises uit te voer, en dit word gewys dat huidige metodes terkortkominge het wat hulle toepaslikheid beperk. Dus is `n nuwe metode geskep wat gebruik maak van simulasie om hierdie probleme te oorkom. Die metode is gevalideer deur om `n gevallestudie uit te voer, waar dit bevestig is dat die metode voordelig is om op `n deursigtige wyse kritiese areas te ontbloot en om organisatoriese belyning te bewerkstellig deur effektiewe kommunikasie van die resultate.

Asset management is getting increasingly important in nearly all fields, especially inthe electric power engineering. It is mainly due to the following two reasons. First isthe high investment cost include the design cost, construction cost, equipment costand the high maintenance cost. Another reason is that there is always a high penaltyfee for the system operator if an interruption happened in the system. Besides, due tothe deregulation of electricity market in these years, the electricity utilities are payingmore attentions to the investment and maintenance cost. And one of their main goalsis to maximize the maintenance performance. So the challenge for the systems is toprovide high-reliability power to the customs and meanwhile be cost-effective for thesuppliers. Reliability Centered Asset Management (RCAM) is one of the bestmethods to solve this problem.The basic RCAM method is introduced first in this thesis. The model includes themaintenance strategy definition, the maintenance cost calculation and an optimizationmodel. Based on the basic model some improvements are added and a new model isproposed. The improvements include the new improvement maintenance strategy,increasing failure rate and a new objective function. The new model is also able toprovide a time-based maintenance plan.The simulation is done to a Swedish distribution system-Birka system by GAMS. Theresults and a sensitivity analysis is presented. A maintenance strategy for 58components and in 120 months is finally found. The impact on the changing failurerate is also shown for the whole peroid.Kapitalförvaltning 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.

Les travaux présentés dans ce manuscrit visent à développer des modèles de coût/performances pour améliorer les décisions de maintenance sur les infrastructures ferroviaires exploitées dans un environnement de plus en plus contraint: trafic accru, détérioration accélérée, temps de maintenance réduits. Les modèles de maintenance proposés sont construits à base de réseaux de Petri colorés ; ils sont animés par simulation de Monte Carlo pour estimer les performances (en termes de coût et de disponibilité) des politiques de maintenance considérées. Ils sont développés aux niveaux "composant" et "réseau", et plusieurs problèmes de maintenance différents sont étudiés. Au niveau "composant" (rail), des politiques de maintenance mettant en jeu différents niveaux d'information de surveillance sont comparées pour montrer l'intérêt de surveiller la détérioration graduelle du composant. L'effet de l'existence d'un délai de maintenance est également étudié pour les politiques conditionnelle et périodique. Au niveau système (ligne), une maintenance mettant en jeu différents types d'inspections complémentaires (automatique ou visuelle) est d'abord étudiée. On s'intéresse ensuite au cas de figure où l'évolution de la détérioration dépend du mode d'utilisation et de la charge de la voie : le problème de maintenance étudié vise alors à définir un réglage optimal des paramètres d'exploitation de la voie (vitesse limite) et de maintenance (délai d'intervention)The aim of this thesis research work is to propose maintenance models for railways infrastructures that can help to make better maintenance decisions in the more constrained environment that the railway industry has to face, e.g. increased traffic loads, faster deterioration, longer maintenance planning procedures, shorter maintenance times. The proposed maintenance models are built using Coloured Petri nets; they are animated through Monte Carlo simulations to estimate the performance of the considered maintenance policies in terms of cost and availability. The maintenance models are developed both at the component and network levels, and several different maintenance problems are considered. At the rail component level, maintenance policies with different level of monitoring information (level of gradual deterioration vs binary working state) are compared to show the benefits of gathering monitoring information on the deterioration level. The effect of preventive maintenance delays is also investigated for both condition-based inspection policies and periodic inspection policies on a gradually deteriorating component. At the line level, a maintenance policy based on a two-level inspection procedure is first investigated. Then, considering the case when the deterioration process depends on the operation modes (normal vs limited speed), a maintenance optimization problem is solved to determine an optimal tuning of the repair delay and speed restriction

Full textAbstract:
Over the last century, there has been growing interest in changing the approach to maintenance management. The current practice for selecting critical equipment and making a decision on the most appropriate maintenance strategy is perceived to have serious limitations, principally because it lacks decision analysis. Due to the complex nature of decision-making in maintenance management, different models have been developed for selecting critical equipment. However, many of these models considered maintenance management as operational concern and ignored the strategic concerns of maintenance management. This thesis builds upon earlier works on decision-making for selecting critical equipment and maintenance strategy. It sets out to construct three hypotheses by introducing evidence from a comprehensive literature review, case study analysis and in-depth interviews. The thesis focuses on artificial intelligence and multi-criteria decision-making techniques (i.e. Fuzzy Logic and Analytical Hierarchy Process) to bridge this gap. It proposes a strategic decision-making model in maintenance and asset management for selecting critical equipment and deciding on a maintenance strategy. The novelty of model is to propose an approach in which maintenance strategy can be applied based on the equipment criticality while not making a trade-off between safety and cost but rather to combine the concern of safety with financial, operational and technical perspectives. The model provides an opportunity to consider safety as the first priority. The research output suggests that existing criticality assessment methods for optimising maintenance delivery have limited value and are suffering from a lack of strategic decision analysis. Multi-criteria decision-making tools could be used to improve decision-making of criticality assessment methods and hence maintenance strategy implementation. The validity of the proposed strategic decision-making model was tested through case study analysis and in-depth interviews. The results suggest that a strategic decision-making model could have a significant impact on improving safety, reliability and operational availability. The strategic decision-making model would enable asset managers to track the consequences of their decisions whilst dealing with maintenance. It is also an effective tool in the hands of a maintenance department to convince their asset managers to make a maintenance investment.

Thesis (MScEng)--Stellenbosch University, 2012.ENGLISH ABSTRACT: The aim of this thesis is to compare the aviation derived reliability metric known as the Maintenance Free Operating Period (MFOP), with the traditionally used, and commonly found, reliability metric Mean Time Between Failure (MTBF), which has over the years shown some innate disadvantages in the field of maintenance. It will be shown that this is mainly due to MTBF’s inherent acceptance of failure and the unscheduled maintenance therewith directly connected. Moreover, MFOP is successfully applied to a mining specific case study, as to date, no other application of the MFOP concept to the mining sector is known. An extensive literature study is presented, which covers concepts relevant to the overall study and which helps to contextualise the problem, revealing the major shortcomings of the commonly accepted MTBF metric. A methodology to analyse systems MFOP performance, making use of failure statistics to analyse both repairable and non-repairable systems, is presented. Validation makes use of a case study which applies the MFOP methodology to a system, specifically in the mining sector. It was shown that MFOP could be applied to the data obtained from the mining sector, producing estimates which were accurate representations of reality. These findings provide an exciting basis on which to begin to facilitate a paradigm shift in the mind set of maintenance personnel, setting reliability targets and dealing with unscheduled maintenance stops. KEYWORDS: Maintenance Free Operating Period, Mean Time Between Failure, Maintenance, Mining
AFRIKAANSE OPSOMMING: Die doel van hierdie tesis is om die Onderhoudvrye Bedryf Tydperk (OBT), ’n betroubaarheidsmaatstaf afkomstig van die lugvaart industrie, te vergelyk met die Gemiddelde Tyd Tussen Falings (GTTF) maatstaf wat tradisioneel in algemene gebruik is, maar wat oor die jare inherente nadele met betrekking tot instandhouding geopenbaar het. Dit sal bewys word dat hierdie nadele hoofsaaklik ontstaan as gevolg van die GTTF se inherente aanvaarding van failure en die ongeskeduleerde instandhouding wat daarmee gepaard gaan. OBT word ook suksesvol aangewend in ’n mynwese-spesifieke gevallestudie, wat aaangegaan is aangesien geen ander sooortgelyke aanwending in die mynwese sektor tot datum bekend is nie. ’n Breedvoerige literatuurstudie word voorgelê wat relevante konsepte dek en die probleem binne konteks plaas, en daardeur die hoof tekortkominge van die algemeen aanvaarde GTTF metriek ontbloot. ’n Metodologie waardeur analise van die stelsel werkverrigting van die OBT uitgevoer kan word met gebruik van onderbrekings statistiek om herstelbaar sowel as onherstelbare stelsels te analiseer, word voorgestel. Geldigheid word getoets deur ’n gevallestudie wat die OBT metodologie aangewend word spesifiek vir ’n stelsel in die mynwese Dit is bewys dat OBT toegepas kan word op data afkomstig van die mynwese sector, en skattings lewer wat akkurate voorstellings is van die werklikheid. Hierdie bevindinge is opwindend, en dit dien as die basis vir ’n die aanwending van ’n paradigmaskuif in die benadering van instandhoudingspersoneel tot die daarstelling van teikens vir betroubaarheid en ook in hul hantering van ongeskeduleerde instandhoudingsophoud.

Full textAbstract:
Across a large part of the UK highways network the carriageway and pavement foundations are drained by Highway Filter Drains (HFDs). A HFD is a linear trench constructed either at the pavement edge or central reserve, fitted with a porous carrier pipe at the base and backfilled with an initially highly porous aggregate material. This arrangement enables the swift removal of surface runoff and subsurface water from the pavement system minimising road user hazards and eliminating risk of structural damage to the pavement sub-base. The highly porous backfill filters throughout its operational life fines washed from the pavement wearing course or adjacent land. HFDs have been found to be prone to collecting near the basal sections (pipe) or surface layers contaminants or detritus that causes the filter media to gradually block. The process has been defined as HFD clogging and it has been found to lead to reduced drainage capacity and potentially severe drop of serviceability. O&M contractual agreements for DBFO projects usually propose in-service and handback requirements for all assets included in the concession portfolio. Different performance thresholds are thus prescribed for pavements, structures, ancillary assets or street lighting. Similar definitions can be retrieved for drainage assets in such agreements, and these include HFDs. Performance metrics are defined though in a generic language and residual life (a key indicator for major assets that usually drives long-term maintenance planning) is prescribed without indicative means to evaluate such a parameter. Most of pavement maintenance is carried out nowadays using proactive management thinking and engineered assessment of benefits and costs of alternative strategies (what-if scenarios). Such a proactive regime is founded upon data driven processes and asset specific ageing / renewal understanding. Within the spectrum of road management, maintenance Life Cycle Costs are usually generated and updated on an annual basis using inventory and condition data linked to a Decision Support Tool (DST). This enables the assessment and optimisation of investment requirements and projection of deterioration and of treatment impacts aligned to continuous monitoring of asset performance. Following this paradigm shift in infrastructure management, a similar structured methodology to optimise HFD maintenance planning is desired and is introduced in this thesis. The work presented enables the identification of proactive maintenance drivers and potential routes in applying a systemised HFD appraisal and monitoring system. An evaluation of Asset Management prerequisites is thus discussed linked to an overview of strategic requirements to establish such a proactive approach. The thesis identifies condition assessment protocols and focuses on developing the means to evaluate deteriorated characteristics of in service drains using destructive and non-destructive techniques. A probabilistic HFD ageing / renewal model is also proposed using Markov chains. This builds upon existing deterioration understanding and links back to current treatment options and impacts. A filter drain decision support toolkit is lastly developed to support maintenance planning and strategy generation.

Full textAbstract:
Reducing the greenhouse gas (GHG) emissions and shrinking the environmental footprint are priority themes of the Federal Sustainable Development Strategy of Canada. Public buildings account for the major portion of the corporate GHG footprint of public sector institutions. Improving the energy efficiency in buildings is vital in achieving the climate action targets pertaining to the public sector. According to Canadian Infrastructure Report Card, the physical condition of public buildings is expected to deteriorate in the future. In order to make the best use of the limited financial resources, hybrid building management plans which combine energy efficiency with physical condition improvement need to be developed. Building maintenance and retrofit plans are formulated for medium and long terms in the capital asset planning process. There is significant uncertainty associated with asset management decision making due to macro-economic variations such as technological advancements and new policies. At present, there are no pragmatic decision making methods that assist building asset management while incorporating future macro-economic changes. This research aims to bridge the aforementioned gap in literature by developing a multi-period asset management framework.
The overall objective of the proposed research is aimed at developing a decision support framework for small and medium scale municipalities in Canada to attain climate action targets of municipal buildings, while prolonging the service life of the building components. This research will help to identify, evaluate, and prioritize maintenance or repair or replacement strategies, and to develop a comprehensive multi-period life cycle asset management plan based on allocated funding, targeted sustainability performance and future macro-economic changes. The findings of this research will extend the current body of knowledge by incorporating potential future technological advancement and climate action targets into the asset management decision making. The proposed asset management decision support framework consists of a retrofit investment planning method, a level of service (LOS) index, life cycle costing (LCC) technique, and a risk based maintenance planning approach. This research is expected to assist at all decision making levels in public sector institutions related to building asset management, and thereby in achieving corporate climate action targets.Applied Science, Faculty of

Full textAbstract:
In the growing power demands, turbine users want to feel confident that their equipment is reliable, efficient, and delivering peak performance every day. Proper care and maintenance of turbine oils is critical to avoiding disruptive and potentially costly downtime, and can help extend oil and component life. The ISO 55001 Asset Management and EN 17485 Maintenance within Physical Asset Management: “Framework for improving the value of the physical assets through their whole life cycle” provides an opportunity for companies to review and improve asset owner and service provider relationships, improve performance and utilisation of assets, reduce operational risk arising from the various stages of asset management and reduce the cost of insurance and ensure regulatory compliance. With such an approach and the use of the best available technology, turbine oil is becoming an asset. This article focuses on turbine oils quality, their degradation, additives and, varnish removal.

Full textAbstract:
Abstract Capital intensive industrial assets require highly specialized maintenance activities. Traditional preventive time-based approach, based on OEM maintenance policies, has been gradually evolving towards more sophisticated condition-based maintenance techniques. Further ISO 55000 states that assets exist to provide value to the organization and its stakeholders (BS ISO 55002, 2014). To develop a successful and modern maintenance program, it suggests having a value-based approach when dealing with maintenance decisions, both financial and non-financial constrains needs to be evaluated when decision taken regarding maintenance actions. Higher values can be reaped from an asset when the maintenance intervals are optimized. By optimization it is envisaged that the right number and type of maintenance tasks, at the right intervals, in the right way is performed on the asset to maximize the risk reduction within available budgetary constraints. The paper presents an overview of an analytics framework for predictive maintenance service boosted by Machine Learning and asset knowledge, applied to turbomachinery assets. Optimization of the maintenance scenario is performed through a risk model that assesses online health status and probability of failure, by detecting functional anomalies or aging phenomena and evaluating their impact on asset serviceability.

Full textAbstract:
The present study was initiated by the Illinois Department of Transportation (IDOT) to better understand characteristics of roadway segments categorized as unmarked in IDOT’s Transportation Asset Management Plan and to suggest recommendations to manage, vacate, abandon, retain, or transfer individual routes. The researchers developed a methodology, labeled JARM, to identify potential candidates for jurisdictional transfer, abandonment (or vacation), reconfiguration, or maintenance. The JARM methodology is an easy-to-use and stand-alone spreadsheet tool for IDOT districts. It includes all unmarked routes as well as their key database variables and visual attributes. The study identified that over 90% of unmarked route centerline mileage is recommended for jurisdictional transfer to move off IDOT’s inventory and to be better served by local agencies, while reducing maintenance costs and future funding needs. To identify maintenance strategies for unmarked routes and low-volume roads, the researchers reviewed best practices of various state agencies and developed treatment catalogues for rural and urban routes. Additionally, they conducted two surveys: (1) a survey of other state DOTs to understand management of similar routes and (2) a survey of local public agencies within Illinois to understand their familiarity and willingness to accept unmarked routes. Twenty-five DOTs responded to the survey to provide insight into how they manage similar routes. The results demonstrated that 70% of local public agency respondents were amenable to a discussion of jurisdictional transfer. The next logical step is to build off this network-level research and to identify execution strategies at the project level in the most cost-effective manner.

Baah, Prince. Implementing Epoxy Injection in Concrete Overlaid Bridge Decks. Purdue University, 2023. http://dx.doi.org/10.5703/1288284317588.
Full textAbstract:
Concrete overlays have proven to be an effective maintenance treatment as they slow de-icing chemical and water penetration into the original deck surface. Typically, due to vibration, structural flexibility, and weak bond between the concrete overlay and deck concrete potentially due to poor construction, de-bonding develops at the boundary between the original deck and overlay. This de-bonding creates voids, providing reservoir for chloride laden water to fill after it penetrates cracks in the surface. Displacing this liquid solution and filling these cracks with epoxy helps reduce freeze/thaw cycling and reduces spalling. The epoxy material protects the bridge deck from moisture and helps support the overlay and prevent it from failing under traffic loads. This leads to an extension of the asset life span and life cycle cost benefit increase. Overall, the bridge infrastructure performance improves significantly with greater mobility and less traffic interruptions due to repairs to bridges on our roadway infrastructures. Epoxy injection helps extends the service life of bridge decks and reduces the need for emergency bridge deck patching and as a result improves safety of road users. Epoxy injection has been added to INDOT’s Maintenance Work Performance Standards during the course of this study.

Full textAbstract:
Within the state of Indiana, there are approximately 9,000 structures with unsupported span lengths that range from 4 ft to 20 ft that the Indiana Department of Transportation (INDOT) is responsible for maintaining. These structures are referred to as large culverts by INDOT. The agency recognized the need to improve culvert inspection procedures so that inspection data that is collected can provide essential information to asset engineers who make decisions regarding culvert management. The purpose of the project described in this report was to identify the best practices for inspection and management of these structures to develop guidelines to optimize the resources allocated for the maintenance and inspection of large culvert structures. The study found that standardizing the inspection process and evaluation criteria for inspection will positively impact the overall performance of the inventory of these structures. A proposed large culvert inspection manual accompanies this report and provides a detailed guide for large culvert inspection.

Full textAbstract:
Construction and concrete production are time-sensitive and fast-paced; as such, it is crucial to monitor the in-place strength development of concrete structures in real-time. Existing concrete strength testing methods, such as the traditional hydraulic compression method specified by ASTM C 39 and the maturity method specified by ASTM C 1074, are labor-intensive, time consuming, and difficult to implement in the field. INDOT’s previous research (SPR-4210) on the electromechanical impedance (EMI) technique has established its feasibility for monitoring in-situ concrete strength to determine the optimal traffic opening time. However, limitations of the data acquisition and communication systems have significantly hindered the technology’s adoption for practical applications. Furthermore, the packaging of piezoelectric sensor needs to be improved to enable robust performance and better signal quality. In this project, a wireless concrete sensor with a data transmission system was developed. It was comprised of an innovated EMI sensor and miniaturized datalogger with both wireless transmission and USB module. A cloud-based platform for data storage and computation was established, which provides the real time data visualization access to general users and data access to machine learning and data mining developers. Furthermore, field implementations were performed to prove the functionality of the innovated EMI sensor and wireless sensing system for real-time and in-place concrete strength monitoring. This project will benefit the DOTs in areas like construction, operation, and maintenance scheduling and asset management by delivering applicable concrete strength monitoring solutions.

Full textAbstract:
Although raised pavement markers (RPMs) have been widely applied by the Indiana Department of Transportation (INDOT), there have been multiple cases where snowplowing activities have damaged pavements as well as the raised pavement markers on INDOT’s roadway assets. Dislodged raised pavement markers could reduce the design life of pavements because they leave openings for water and debris to infiltrate through pavement section. Interviews with INDOT personnel indicated that the proper installation of the markers and careful attention to the tooling of the center line of the concrete pavements could alleviate this problem. To explore issues related to the proper installation of RPMs, this study (INDOT/JTRP SPR 4318) was launched by the Indiana Department of Transportation (INDOT)/Joint Transportation Program (JTRP) to develop a synthesis of current practices on installation and maintenance of raised pavement markers at State Transportation Agencies (STAs) in the U.S. The study was conducted using a qualitative exploratory approach focusing on the review of current practices in installation and maintenance of raised pavement markers among STAs. Survey analysis and focused interviews with personnel from STAs, along with reviews of documents provided by STAs were the avenues used for data collection in this project.

Public Willingness to Raise Transportation Revenues, Priorities for Transportation Spending, and Preferences for Types of Transportation Revenues: Evidence from Montana’s Billings and Missoula Small Urban Areas. Montana State University, July 2023. http://dx.doi.org/10.15788/1700173900.
Full textAbstract:
This project analyzed public willingness to raise transportation revenues, public priorities for transportation spending, and public preferences for transportation revenue types using recent household travel surveys for the small urban areas of Billings and Missoula. The share of the public willing to pay more taxes or fees for transportation improvements was 44% in Billings and 36% in Missoula (including neutral or undecided responses). This level of public support for increased transportation revenues is perhaps higher than generally perceived by leaders reluctant to publicly support a gas tax increase. Our results regarding transportation spending priorities are consistent with the prioritization of preserving existing transportation assets. Maintenance and repair of existing infrastructure received the most support of transportation spending options in both the Billings and Missoula survey samples. Our results regarding the preferred type of transportation revenue mechanism (available only for Missoula) suggested that a plurality of the sample (35% including neutral or undecided responses) preferred a $0.02 per gallon increase in fuel taxes to other options (such as an increase in sales or property taxes). Together, our results suggest a public willingness to more adequately fund transportation investments, a preference for spending on existing transportation assets, and a preference for more direct road user charges over less direct alternatives.
