The Life Cycle Management System (LMS) aims at supporting decision-makers and engineers in their efforts to achieve a more optimised proactive life cycle design and maintenance management strategy. LMS is an open and integrative system, which has to be adapted and developed in order to meet the needs and requirements of users. This process should be geared to and governed by the clients. The Architecture, Engineering, Construction and Facility Management (AEC/FM) sector includes all varieties of clients and stakeholders, all of them having different qualifications, possibilities and requirements for implementing, or increasing the feature of predictive maintenance management and optimised proactive strategies. The possibilities of adopting predictive maintenance management are dependent on the availability of performance-over-time and service life forecasting models and methods. The relevance of these models and methods depends on the required level of detailing. Furthermore, the use of the models and methods depends on the availability of reliable input data, such as material data and environmental exposure/in-use condition data. The thesis aims at analysing the possibilities of implementing predictivity in different fields of applications and at evaluating relevant tools facilitating management of information associated with predictive maintenance management systems. The thesis includes studies of three different clients and fields of application; Swedish Road Administration – management of bridges, Locum AB – management of hospital buildings, and Gävle Energi AB – management of district heating distribution systems. While the Swedish Road Administration is responsible to ensure an economically efficient, sustainable transport system for the society throughout the country, Locum AB and Gävle Energi AB compete on an "open" market. The Swedish Road Administration have gathered information about their bridges since 1944, for what reason their bridge management system includes a large amount of valuable data for performance-over- time analyses and service life forecasting. Locum AB has recently begun to systematically gather condition data, why the amount of data is limited. However, since the performance of buildings generally is well known, it is assumed that possibilities of implementing predictive maintenance management tools are rather good. Since district heating pipes are buried into the ground, it is difficult to assess the condition. Therefore, data for service life estimation rely mainly on damage reports. Environmental exposure data on macro or meso level can be obtained from meteorological and environmental institutes, thus making it possible to apply available dose-response and damage functions. Environmental exposure data on a micro level are lacking. Guidelines, methods and tools for environmental measuring and modelling on a micro level are therefore strongly needed. Efficient management of information plays an important role in predictive life cycle management systems. The ongoing development and implementation of open Building Information Model (BIM) tools in the AEC/FM sector is a promising progress of making the information management more cost effective and valuable, especially when open BIM solutions being fully integrated into the AEC/FM business. Geographical Information Systems (GIS) are tools for efficient handling of spatial positioned information. GIS provide possibilities of processing and presenting, e.g., environmental exposure data and environmental risk factors. / QC 20100716

The road network is extremely valuable. Road Administrationsare expected to invest maintenance funding in a way thatreturns maximum benefit to road users. Cost-benefit analysis isone method to ensure that an adequate return in terms ofbenefits results from committing expenditure. Today,cost-benefit calculations are frequently used as a base fordecision making of investments. The surges for such methods inthe maintenance management sector are increasing. Up to the present, one reason for not analysing costs andbenefits for various maintenance management measures has beenthe lack of knowledge about comfort benefits for road users inquantitative monetary terms. The aim with this thesis is toinvestigate motorists’apprehension of pavementmaintenance management and winter maintenance operations. Thefinal goal is to find out their willingness to pay fordifferent levels of road maintenance management. Those valuescan later be used in cost-benefit calculations and also ineffect models of road maintenance management. Due to the pioneer status of this study, focus groups andin-depth interviews as well as a number of pilot studies havebeen carried out before a main survey with stated choiceexperiments could be designed. These exploratory studies showedthat the interviewees were familiar with the types of roadsurface damage that exist and in many cases mastered the sameterminology as the Road Administration and others. Showingpictures of well-known types of road damage lead to highermonetary valuations of getting better road standard incomparison with just text descriptions. One reason for thatcould be the requisite severness of the damage in order toillustrate a certain road maintenance shortage. The respondentswith the text descriptions could have stated their preferencesfor an, in their own minds, average shortcoming while the groupwith access to photograph of road damage all saw the samesevere damage. Illustrations of different road maintenancestandards make it possible to control the respondentsinterpretation of the maintenance management standard valuatedbut could lead to high monetary estimations. Driving comfort was very important to the interviewees inthe exploratory studies. That was manifested in the pilotstated choice surveys, which resulted in high willingness topay for better pavement management. The main study consisted of two surveys; the first one wasabout pavement maintenance management and was carried out inOctober to November 2000 and the second one took place inFebruary to March 2001 and was about winter maintenanceoperations. Both the pavement and the winter survey includedattitude questions and two stated choice experiments. Theresult showed that the maintenance management status of theroad network was important to car users. For example, the worstpavement damage was roughness; the motorists were willing topay 1.7 SEK (Swedish Crowns) per kilometre to avoid roadsdamaged in their full length. The least harmful damage of thosestudied was cracks; the willingness to pay to avoid that was0.5 SEK per kilometre. For more rapid snow clearance, the carusers were willing to pay 60 to 80 SEK per year for getting theroads cleared from snow one hour earlier than the currentstandard implies. The willingness to pay for driving on bareroads in comparison with snow roads was 0.4 SEK per kilometre.Statistical tests on the models showed that the parametervalueswere well estimated. In the pavement as well as in the winter survey, a clustergroup analysis was performed in order to test the heterogeneityof attitudes and behaviour to road maintenance management. Theanalysis resulted in two separate groups in each survey. Onegroup consisted of drivers who reported to be very influencedby the level of maintenance management regarding chosen speed,joy of driving and so on. The other group reported to be lessinfluenced and had lower acceptance of higher road tax for thepurpose to increase the maintenance management standard.Separate stated choice models revealed that the differences inattitudes could also reflect the respondents’willingnessto pay for higher road maintenance standard. However, thedifferences were only small and the different groups’monetary valuations were not found to be significantlydifferent from each other. The result of this study, better knowledge aboutmotorists’apprehension of maintenance management, theirattitudes to driving comfort and road standard and theirmonetary valuations of different levels of pavement maintenanceand winter maintenance operations, opens up the possibility tomake cost-benefit analysis of various maintenance managementprojects. The impact of the monetary values found in this studyhas been studied in a limited cost-benefit analysis. <b>Keywords:</b>stated choice, stated preference, valuationsof maintenance management, driving comfort, road standardevaluation

Effective and efficient operations management is the cornerstone of any company's success. Presently, because of cost-cutting pressures, all investors look out for companies' operations before making any investment commitment. The South African Government (through the Department of Public Enterprises), as an owner and investor in Eskom, is looking at optimising operational excellence within state-owned enterprises like Eskom. Eskom is presently experiencing problems with increased electricity consumption which it cannot meet due to the limited plant capacity it presently has. These challenges are forcing Eskom to be more efficient and effective in management of the present plant assets (like Matimba Power Station) it presently operates. Matimba Power Station has consistently shown improvement in the areas of plant, financial and operations performance over the last three years. It is presently the standard bearer for the whole Eskom in terms of plant and operational performance. Asset management (through maintenance and management thereof), especially preventative management with in a power utility like Eskom, is a critical factor because supply (generation of electricity) has to meet demand (consumption of electricity) instantaneously as electricity cannot be saved. The planning, scheduling and execution of maintenance (through a work management process) to ensure success of business operations are very critical. An Eskom document titled Routine Work Management Manual emphasised the criticality of preventative management and included a six-step process of work management within the power generation business. The Japanese success in ensuring that operations costs are limited by implementing total productive maintenance (which includes work management) is suggested in the study as a way to go for operational success at Matimba Power Station. Many of the research studies done at Eskom in regard to maintenance were based on and confined to a sampling population of senior staff members like managers, engineers and supervisors. Experience has shown that progress of implementing change (whether in systems or structures) is slow if there was no proactive involvement of all participants and stakeholders, especially employees at lower levels involved in operations. A work management process, which is one of the pillars of total productive maintenance, was recently implemented at Matimba and is currently experiencing teething problems which are being attended to. Employee involvement in making sure of the success of work management is critical. The study investigates the implementation of work management from the employees' perspective in order to address problems for possible full implementation of total productive maintenance. / Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2010.

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.

Cette thèse propose un outil d’aide à la décision pour la gestion de processus de maintenance basée surune affectation optimale des ressources humaines afin d’améliorer la performance de la maintenance.En effet, une bonne performance de la fonction maintenance est indispensable pour maintenir laproductivité des installations industrielles, et donc de la compétitivité des entreprises manufacturières.L’approche que nous développons dans ce manuscrit procure un cadre de référence des leviersd’actions envisageables pour mesurer, évaluer, améliorer et optimiser la performance de lamaintenance. Nous prenons en considération un problème d’affectation des ressources humaines, quiprend en compte non seulement leurs disponibilités et compétences, mais aussi la gestion des urgencesd’intervention sur terrain.La méthode que nous proposons est basée sur un modèle de simulation à événements discrets,reproduisant au mieux un service de maintenance. Ceci nous a permis d’évaluer la situation via desindicateurs de performance présélectionnés. Pour optimiser le système, nous proposons un couplagedu modèle de simulation avec un module d’optimisation indépendant qui se réfère à une métaheuristiquebasée sur une approche Pareto. Notre proposition a été testée dans une entrepriseindustrielle réelle.L’approche que nous proposons donne un ensemble de solutions d’affectation des ressourceshumaines, aidant le décideur à mieux gérer l’indisponibilité de ses outils. Nous obtenons de bonsrésultats en un temps raisonnable. / In this thesis, a decision-making tool for maintenance management process based on assignment ofhuman resources is proposed in order to improve maintenance performance. An optimal maintenanceperformance is indispensable to guarantee the productivity and competitiveness of manufacturingcompanies.The proposed approach provides a framework of different possible levers to measure, evaluate,improve and optimize the maintenance performance. The assignment of human resources problem isconsidered. It takes into account different constraints like human resources availability, competences,urgency degree management of interventions requests etc.The proposed method is based on a discrete event simulation model, providing a better presentation ofthe maintenance service and better comprehensive thanks to the performance indicators. To improveuntil optimize the model, a simulation-based Pareto optimization method is introduced. Optimizationmodule was coded on independent programs in order to provide an opportunity of control thesimulation based optimization process.The proposed simulation based optimization method find good solutions in a reasonable amount oftime. Applying this technique on an industrial case-study, we show that it is more effective indetecting real faults than existing alternatives. The approach can be extended to cover other domainsand other types of simulation models.

Este trabalho apresenta um estudo de confiabilidade e manutenção em sistemas de expedição de produtos de mineração. O estudo envolveu o desenvolvimento e aplicação de um simulador que permite prever (e utilizar) janelas de oportunidade para manutenção. O simulador foi desenvolvido considerando o caso da mina de Carajás no Pará, uma das maiores do país. Para tal, foi elaborado um modelo heurístico para prever as janelas de oportunidade, de forma a capturá-las para atividades de manutenção. Esse modelo foi baseado em conhecimentos prévios do pesquisador sobre o problema e estudo da lógica de operação do sistema, dando origem a um aplicativo que foi nomeado Mosaico de Simulação da Expedição. Apoiado no modelo desenvolvido e nos resultados de um grupo focado com lideranças e especialistas com experiência técnica no assunto, foram estabelecidas novas diretrizes e procedimentos de manutenção, buscando otimizar o aproveitamento das oportunidades e, consequentemente, melhorar o desempenho do sistema em estudo. O trabalho foi dividido em três etapas principais, sendo: (i) Proposição de um modelo para previsão de janelas de oportunidade para sistemas de expedição para produtos de mineração, adequado ao caso da mina de Carajás; (ii) Estabelecimento de uma proposta de estrutura e rotina da manutenção necessária para aproveitar a previsão mais precisa das janelas de oportunidade de intervenção. e (iii) Aplicação do modelo em estudo junto ao sistema real de expedição na mina de Carajás, visando avaliação e aprimoramento do mesmo. Os resultados iniciais obtidos com a aplicação da sistemática desenvolvida indicaram um aumento de 15,9% no MTBF em comparação com a média dos valores apurados do trimestre anterior à aplicação do estudo. Estima-se que este incremento proporcionou um aumento de 422 toneladas/dia no Volume de Minério Expedido na mina de Carajás no Pará, usando a mesma base de comparação. A partir desta estimativa, e considerando que todas as condições, recursos, estrutura operacional, preços e demanda por minério de ferro à qual o estudo foi aplicado sejam mantidas, pode-se aferir um ganho de faturamento mensal de US$ 1,04 milhões, totalizando US$ 10,7 milhões em um ano. Ganhos maiores podem ser esperados à medida em que a equipe de manutenção obtenha maior experiência no uso da sistemática proposta. / This work presents a reliability study of maintenance in expedition systems for mining products. The study involved the development and implementation of a simulator that can predict (and use) windows of opportunity for maintenance activities. The simulator was developed considering the case of the Carajas mine in Pará, one of the largest in the country. For such system, a heuristic model for predicting the windows of opportunity in order to capture them for maintenance activities was design through the application of a simulator. This model was based on the researcher's prior knowledge about the problem and operation logic of the system, resulting in an applet called Expedition Mosaic Simulator. New guidelines and maintenance procedures have been established, supported in the simulator and a focus group development that included leaders and specialists with expertise in the subject. The main objetctive was optimize the opportunities and consequently improve the performance of the system under study. The work was divided into three main stages, namely: (i) Proposal of a model to predict the windows of opportunity for maintenance activities in the expedition systems for mining products, appropriate to the case of Carajás mine; (ii) Establishment of a proposal for maintenance structure and routine required to capture the most accurate forecast of windows of opportunity, and (iii) Application of the model at the actual expedition system in the Carajás mine, aiming to evaluate and improve it. Initial results obtained by applying the developed systematic indicated an increase of 15.9% in the MTBF value compared to the average values from the previous quarter to the implementation of the study. It is estimated that this results had also increased the Volume Loaded in Carajas mine in Pará in 422 tonnes / day of iron ore, using the same basis of comparison. Based on this estimative, and considering that all the conditions, resources, operational structure, prices and demand for iron ore at which the study has been applied are kept, a gain of US$ 1.04 million in monthly sales might be infered, thus totaling US$ 10.7 million in one year. Further gains can be expected as the maintenance team get experienced in the use of systematic proposed.

Based on this estimative, and considering that all the conditions, resources, operational structure, prices and demand for iron ore at which the study has been applied are kept, a gain of US$ 1.04 million in monthly sales might be infered, thus totaling US$ 10.7 million in one year. Further gains can be expected as the maintenance team get experienced in the use of systematic proposed.
