The systematization of the maintenance management – although it is quite a recent approach as a subject of science that demands putting the strategic and operational levels closer – is considered essential in the search for certain competitive advantages like cost reduction, production pipeline reliability, and service providing. Since roads are viewed as assets worth preserving and managing, such managing has to be carried out in a systemic way. The roads here are the unpaved roads located into forestry exploration entrepreneurship for cellulose extraction. This research presents a conceptual proposal to model an unpaved road maintenance management system located into forestry exploration entrepreneurship for cellulose extraction. This research deals with road maintenance management systems, management and maintenance applied to roads as well as presents a particular point of view related to the evolution of the road maintenance management, and it also deals with the two approaches related to maintenance management, the network-level and the project-level approaches. This work also deals with unpaved roads, characterization and importance of such roads, an approach on the concept of serviceability applied to unpaved roads, mechanisms of deterioration, models to forecast performance, and alternatives of interventions addressed to maintain those roads. It also pinpoints benefits associated with the maintenance, ways to priorize interventions or roads, and some economic and financial analysis. It also works with the forestry exploration entrepreneurship for cellulose extraction, shows a broad vision of that entrepreneurship, approaches the forestry harvesting system, brings a brief discussion about the road maintenance under private entrepreneurships and discusses economic advantages of managing the maintenance of unpaved road network. All concepts previously discussed are the foundation of the proposed unpaved road maintenance management system. Among such concepts is the use of Relational Unified Process tool, a proposal addressed to carry on the unpaved road network management process, suggestions for maintenance polices and alternatives of maintenance interventions, and ways of collecting data related to the vehicle fleet and the condition of the road network. At the end, it presents some decision trees addressed to the selection of maintenance interventions, such trees take into account the length and the severity of the defects identified.

M.Phil. / In modern society, professional engineers, technologists and technical managers are responsible for the planning, design, manufacture, maintenance and operation of the processes and systems ranging from simple processes to complex systems. The failure of these can often cause effects that range from inconvenience and irritation to severe impact on the society and its environment. Users, customers and society in general expect that products be reliable and safe at all times (Allan & Ballinton 1992). The biggest investment in any plant is, arguably, on individual plant equipment. It is therefore reasonable to give the greatest attention possible to the health and integrity of equipment that form part of the chemical process plant.Most of plant failures occur without warning and this result in equipment breakdowns, huge production losses and expensive maintenance. The reaction to plant failures has, in most cases, been a reactive maintenance which means that the plant equipment must fail before the cause of fault is investigated and the equipment is repaired. Reactive maintenance has shortcomings in that it is successful in solving problems temporarily but does not guarantee prevention of fault recurrence. Equipment and process failures waste money on unreliability problems. The question that arises is. ‘How reliable and safe is the plant during its operating life?’ This question can be answered, in part, by the use of quantitative reliability evaluation. The growing need to achieve high availability for large integrated chemical process systems demands higher levels of reliability at the operational stage. Reliability is the probability of equipment or processes to function without failure when operated correctly for a given interval of time under stated conditions. This research dissertation is aimed at developing equipment optimisation program for the chemical process plant by introducing a logical approach to managing the maintenance of plant equipment. Some relevant reliability theory is discussed and applied to the Short – Path Distillation (SPD) plant of SASOL WAX. An analysis of the failure modes and criticality helps to identify plant equipment that needs special focus during inspection.

La investigación se realizó en una empresa ubicada en la región Lambayeque, dedicada a producción y comercialización de papel higiénico institucional, cuya problemática es la baja productividad de su proceso productivo, debido a los paros repetitivos y repentinos de las maquinarias, generados por una inadecuada gestión de mantenimiento. Es por ello, que el objetivo general del estudio fue mejorar la gestión de mantenimiento para aumentar la productividad del proceso de elaboración de papel higiénico institucional. Se realizó un diagnóstico del proceso productivo, que consistió en la toma de tiempos de cada actividad, utilizando como herramientas de apoyo un cronómetro y la metodología Mundel; además, se aplicó una lista de verificación de la metodología 5S, un análisis de causa raíz, análisis de criticidad y se calculó los indicadores de producción y productividad. A continuación, se realizó una evaluación de alternativas y se seleccionó como propuesta un plan de mtto preventivo basado en RCM para la gestión, estimando un incremento de 5,22 a 5,55 und/op-h en la productividad de mano de obra, y un aumento de 56,98% a 60,53% en la productividad basado en la utilización y eficiencia. Asimismo, con una disponibilidad de 94,7%, se estima un incremento producción anual de 2443 unidades. Finalmente, se realizó el análisis económico y financiero de las propuestas, estimando una inversión de S/. 16 900, con un VAN de 7 460, un TIR de 44% y una relación costo-beneficio de S/. 6 435 al tercer año de su implementación, por lo que se concluye que la propuesta es viable. / The research was carried out in a company located in the Lambayeque region, dedicated to the production and commercialization of institutional toilet paper, whose problem is the low productivity of its production process, due to repetitive and sudden stoppages of machinery, generated by inadequate management of maintenance. That is why the general objective of the study was to improve maintenance management to increase the productivity of the institutional toilet paper manufacturing process. A diagnosis of the production process was carried out, which consisted of taking the times of each activity, using a stopwatch and the Mundel methodology as support tools; In addition, a checklist of the 5S methodology was applied and the production and productivity indicators were calculated. Next, an evaluation of alternatives was carried out and a preventive maintenance plan based on RCM was selected as a proposal for management, estimating an increase from 5.22 to 5.55 und / op-h in labor productivity, and a 56.98% to 60.53% increase in productivity based on utilization and efficiency. Likewise, with an availability of 94.7%, an annual production increase of 2443 units is estimated. Finally, the economic and financial analysis of the proposals was carried out, estimating an investment of S /. 16,900, with a NPV of 7,460, an IRR of 44% and a cost-benefit ratio of S /. 6,435 in the third year of its implementation, so it is concluded that the proposal is viable.

As for the methodology, it is of a qualitative approach, the technique used is indirect, since the tools of observation and review of reports will be used (as support for an interview).

El sector textil y confecciones es uno de los sectores con mayores expectativas de crecimiento sostenible de la industria y uno de los que mayor competencia acumula con otros países del sector internacional. Este sector abarca diferentes tipos de procesos, que van desde tratamiento de fibras, hilatura, tejido y confección. El presente análisis recae sobre la baja disponibilidad que presenta los equipos en el proceso de teñido. Este proceso se mide a partir de los reprocesos que existen debido a que se ejecuta mantenimientos correctivos, el cual afecta la producción en el teñido de telas. Asimismo, se logra evaluar el tiempo promedio entre fallas (MTBF) y el tiempo promedio de reparación (MTTR), lo que indica la variabilidad por debajo del objetivo esperado por la organización. Por otro lado, en el tercer capítulo se desarrolla le propuesta de mejora a partir del desarrollo del estado del arte del primer capítulo. Para ello se propone la metodología da seguir de acuerdo con una combinación de RCM y TPM. Bajo esta metodología se desarrolla diferentes actividades y estrategias que permitirán detectar equipos críticos e implementar planes de mantenimiento preventivo mecánico y eléctrico. Además, se incluye como parte de este sistema la implementación de un mantenimiento basado en condición (predictivo) y autónomo. Finalmente, el tercer capítulo finaliza con el soporte de la metodología 5 ‘’S’’ y la evaluación económica a partir de la estructura de costos que tiene prevista el proyecto. Finalmente, en el capítulo cuatro se presenta la validación de la propuesta de mejora a partir de la validación de los resultados en el software Arena. Ello permite concluir que los indicadores MTTR y MTBF ha logrado alcanzar los objetivos presentados en la propuesta. / The textile and garment sector is one of the sectors with the highest expectations of sustainable growth in the industry and one of the sectors with the highest competition with other countries in the international sector. This sector covers different types of processes, ranging from fiber treatment, spinning, weaving and confection. The present analysis falls on the low availability that presents the equipment in the process of dyeing. This process is measured from the reprocesses that exist due to the execution of corrective maintenance, which affects the production of fabric dyeing. Likewise, it is possible to evaluate the average time between failures (MTBF) and the average repair time (MTTR), which indicates the variability below the target expected by the organization. On the other hand, in the third chapter the improvement proposal is developed from the development of the state of art of the first chapter. For this, the methodology to be followed is proposed according to a combination of RCM and TPM. Under this methodology, different activities and strategies are developed to detect critical equipment and implement mechanical and electrical preventive maintenance plans. In addition, the implementation of a maintenance based on (predictive) and autonomous condition is included as part of this system. Finally, the third chapter ends with the support of the 5 '' S '' methodology and the economic evaluation based on the cost structure planned by the project. Finally, chapter four presents the validation of the improvement proposal based on the validation of the results in the Arena software. This allows concluding that the MTTR and MTBF indicators have achieved the objectives presented in the proposal. / Tesis

Entretanto, com o crescimento da automação e da mecanização, aspectos como a confiabilidade e a disponibilidade tornaram-se pontos–chave em termos de competitividade. Isso se dá pelo fato da eventual paralisação das operações ter um impacto nos custos, na qualidade e na confiabilidade dos produtos e serviços. Além de que, o advento da cobrança cada vez maior por qualidade na execução dos serviços, em geral, e do transporte público, em particular. Da mesma forma, essa busca por competitividade precede uma busca incessante por melhores índices de eficiência, seja na empresa pública ou na privada. Este estudo, em particular, tem como objetivo propor um modelo de identificação dos Fatores Críticos de Sucesso (FCS) do sistema de gestão da manutenção da empresa de Trens Urbanos de Porto Alegre S.A. (Trensurb), a fim de reduzir o impacto da atuação da atividade de manutenção no desempenho do negócio da empresa. Ainda na esfera dos objetivos, essa pesquisa construí a estrutura Sistêmica que reflete o modelo do sistema de Gestão da Manutenção da Trensurb, possibilitando a compreensão de que forma as variáveis envolvidas nesse contexto se interelacionam a partir do Pensamento Sistêmico. Ainda construir arquétipos que reflitam a realidade do modus operandi do sistema de gestão da manutenção da Trensurb. E por fim, analisa a estrutura construída de modo a identificar os FCS - Fatores Críticos de Sucesso (FCS) do sistema de gestão da manutenção por meio do Pensamento Sistêmico. Identificamos como por meio do Pensamento Sistêmico (PS) que esse modelo serve como uma alternativa aos modelos usuais de análise da gestão da manutenção. Com a utilização de métodos qualitativos, levanta-se uma série de relações entre as inúmeras variáveis existentes na atuação do sistema de gestão da manutenção. Como resultados foi possível identificar que a área de atuação da equipe de manutenção terceirizada, o modelo de mix de contratação da manutenção própria x terceirizada, a disponibilidade Operacional, e o MKBF - Mean Kilometer Between Failures, correspondem aos Fatores Críticos de Sucesso do sistema de gestão da manutenção da Trensurb. Além disso, foi possível a contrução da tríade da sustentabilidade da manutenção. Sendo conduzido seguindo os preceitos de um Estudo de Caso, a pesquisa evolui no campo de estudo dos fatores críticos de sucesso, não se limitando a apresentar somente uma abordagem pontual, mas evolui através proposição de uma metodologia de levantamento dos Fatores Críticos De Sucesso com o uso do Pensamento Sistêmico. / The maintenance activity is equipment and facilities, is a routine function in most large companies. However, with the growth of automation and mechanization, aspects such as reliability and availability have become key points in terms of competitiveness. This is partly because of the possible shutdown of operations have an impact on costs, the quality and reliability of products and services. Apart from that, the advent of increasingly charging for quality in the execution of services in general and public transport in particular. Similarly, this search for competitiveness precedes a constant search for better levels of efficiency, whether in public or private company. This study, in particular, aims to propose an identification model of the Critical Success Factors (CSF) of the company's maintenance management system Urban Train of Porto Alegre SA (Trensurb) in order to reduce the impact of the performance of maintenance activity on the company's business performance. Even in the sphere of goals, this research built the systemic structure that reflects the model management system Maintenance of Trensurb, allowing us to understand how the variables involved in this context interrelate from Systems Thinking. Still build archetypes that reflect the reality of the modus operandi of the maintenance management of Trensurb system. Finally, it analyzes the structure constructed to identify the FCS - Critical Success Factors (CSF) maintenance management system through Systems Thinking. As identified through the Systems Thinking (PS) that this model serves as an alternative to the usual models of analysis of maintenance management. With the use of qualitative methods, raises a series of relationships between the numerous variables in the performance of maintenance management system. As a result it was possible to identify the area of operation of outsourced maintenance staff, the hiring mix model's own x outsourced maintenance, operational availability, and MKBF - Mean Kilometer Between Failures, correspond to system Success Factors Critical maintenance management of Trensurb. Furthermore, the construction of sustainable maintenance Triad was possible. Being conducted following the precepts of a case study, the research progresses on the critical success factors field of study, not limited to display only a specific approach, but evolves through proposal of a survey methodology for Critical Success Factors with use of Systems Thinking

Maintenance is one area of business that recently has been considered as an activity contributing efficiently to the companies' strategic goals. Understanding the way maintenance could utilise modern technology such as computerised tools or digital data processing is one way to make maintenance profitable. Current research lack appropriate methods for determining data and IT requirements, as well as understanding the way IT could be utilised for enhancing maintenance profitability. This thesis studies and develops tools, methods and theories of how information technology can be utilised for maintenance management in order to reach profitable maintenance. The main research problem is therefore: What are the demands on information technology systems to achieve profitable maintenance? The main problem has been divided into three research questions: RQ1) What are the demands on data and information technology systems for strategic management of maintenance?, RQ2) How can we identify relevant data and information technology systems required to achieve cost-effective maintenance decisions? and RQ3) How can we describe the utilisation of information technology within maintenance? This thesis is based on a systems theory approach, where maintenance is not seen as an isolated activity, but something that interacts, affects and is affected by several other activities, such as production, logistic and quality. Several methods have been used for answering the research questions, but the theory-testing case study method dominates. Main results achieved in the thesis are models and theory for 1) creating a relevant set of data for cost-effective mainte-nance decisions, 2) monitoring the performance of maintenance, suggest invest-ment possibilities and show maintenance contribution on company strategic level, 3) identifying IT systems requirements demanded to achieve profitable maintenance and 4) assessing the IT maturity of a maintenance organisation for the effective utilisation of IT systems. As an illustrative example of computerised maintenance management demands a conceptual decision support model has been developed, which aims at filling the gaps of poor IT coverage for strategic maintenance decision-making. This thesis concludes that the demands of data and IT applications must be connected to the overall maintenance demands, which are reflected in the maintenance goals, purposes and strategy, in order to achieve profitable maintenance. Furthermore, structured methods that ensure the connection between maintenance business goals and data or IT demands are of importance. The ability to make use if IT within maintenance is reflected in the relative IT maturity of the maintenance organisation. Being able to define the IT maturity allows for choosing the most appropriate IT tool to invest in, so that current and future needs of IT support are also covered for with maximum benefit and minimum cost.

Maintenance has evolved over centuries and has played significant role for growth of organizations. Maintenance history is differentiated by three generations, the development of maintenance considered from being “necessary evil” to “profit contributor”. Many literatures have discussed maintenance for optimization and increasing profitability but little on the factors which influence on the future of maintenance. Maintenance should be considered as a “competitive factor” in the future. Many trends have evolved in production and every trend had a major contribution towards production development. The successful implementation of the trends is considered to be a major challenge. Little literatures have talked on the emerging trends and challenges in production. The thesis reviews the historical development of maintenance over generations and presents the key factors which play a major role during the fourth generation, and also identifies the emerging trends and challenges to be faced by production. The literature review, interviews and surveys were used in this thesis. Academic researchers and industrial experts from both maintenance and production department answered the interview and survey questions for this research. The key factors for the proposal of fourth generation of maintenance and the emerging trends and challenges to be faced by production are presented. The result from the research questions and the empirical findings are summarized in a framework that will enable readers to know the historical development of maintenance, the key factors to be considered for the fourth generation of maintenance and the emerging trends and challenges to be faced by production in future. In addition, the thesis also discusses the impact of information technology on the future of maintenance and the effect of sustainability in the future of production.
