Most companies focus their thinking on the production system's assets, those that generate profits, and rarely look to the periphery, to the enabling systems, those that carry out the effort in order that the production department can continue to do its job, those that provide the “support” to the system. What is “supportability”? It is not a widespread term; it is in fact associated to “maintenance logistics,” and this is only the simplest of its meanings, when in reality it crosses horizontally the whole organization, it is transversal to the MGM model, and it is present in all of the phases of assets and systems' life cycle. Throughout the chapter, different concepts will be developed to show how support is integrated into the proposed maintenance management model (MMM) at each stage of the asset life cycle and how it impacts their costs.

Responsibility and reliability are very important for electricity subscribers. Due to their extent, these networks face a variety of challenges, and most of them are recurring but can be prevented if the root causes are identified. One of the methods to identify the root of network problems is to use the RCA method in the analysis of blackouts. RCA is an approach that systematically investigates adverse events and, by gathering evidence and documentation, finds its root causes and offers solutions to address them. Finally, it monitors the implementation of solutions and evaluates their effectiveness. In this chapter, while introducing some of the challenges of medium voltage power supply networks, the root of the problems are extracted, and corrective solutions are presented in three sample problematic feeders. After extracting the solutions, they are divided into two categories: the first category is the solutions specific to the sample feeder, and the second category is the solutions that can be generalized to other parts of the power supply network.

IoT solutions represent one of the most powerful approaches towards asset and maintenance management supporting a multi-user environment that can be adopted to monitor machine and guide decision-making at different levels. Several studies discussed the benefits that may be achieved, but few studies discussed how to implement such a complex process that should consider a systematic approach in the development of the infrastructure, platform content, analytics, and internal processes reengineering. To this purpose, the presented chapter describes an IoT platform implementation in a manufacturing company. Specifically, the case study illustrates the steps that have been followed to develop and implement the IoT solution, namely (1) definition of the platform desired functionalities; (2) reengineering of the business processes affected by the platform; (3) development of the proof of concept of the platform dashboards, also considering the data to be sent to the platform; and (4) the implementation of the IoT platform with the connection of customer machines.

The chapter explains in detail the maintenance management model (MMM) taken as a reference for the development of the book. The chapter is based on the eight phases of the MMM. The first three blocks determine the effectiveness of the management; the following blocks assure the same efficiency and continuous improvement in the following way: Blocks 4 and 5 include actions for the planning and scheduling of maintenance, including, of course, the capacity of planning of department of maintenance. Blocks 6 and 7 are dedicated to the evaluation and control of the maintenance and the cost of assets throughout their life cycle. This chapter of introduction briefly summarizes the process and the reference frame necessary for the implementation of the MMM. This chapter also presents the relationship between the eight phases of the maintenance management model proposed and the general requirements of the asset management standard ISO 55000 to show how the gradual implementation of the MMM largely covers the requirements of the standard ISO 55000.

Experience shows that the implementation of the MMM model in developing countries requires the consideration of specific feature of these countries. In this chapter, first, the frameworks and models of maintenance excellence are reviewed. Of course, the purpose of this chapter is not to compare these models. Then, the characteristics of maintenance in developing countries is explained. Then, the “iREAM3 framework” based on the “MMM model” and concepts of asset management in industries and organization of developing countries is presented, which is compatible with the characteristics of these countries and has been implemented, developed, and updated in some organization in these countries. Then, how it covers the ISO 55000 standard clauses is explained. In the following, the method and principles of evaluating the organization and the requirements of preparing a suitable roadmap for excellence are introduced. Finally, the audit results of implementation iREAM3 framework in these countries are presented in some companies, organizations, and industries from different fields.

Human reliability and human error are factors that are present in all areas: industrial, economic, social, etc. All these areas require to a greater or lesser extent a physical and mental effort to satisfy their own needs, those of others, or established requirements that, depending on the circumstances and the nature of the person, can lead to errors. Certainly, it is not possible to find a single human reliability method that can meet all the expectations and technical demands related to the analysis of human errors. However, it is important to note that the orientation of all human reliability methods is focused on the study and analysis of the risk factor (frequency by consequences). In other words, as can be observed throughout this chapter, all human reliability methodologies seek to help us reduce the uncertainty in the process of evaluating the frequencies of unforeseen events (human errors) and the consequences that such human errors can bring to safety, the environment, and the operations within the framework of an industrial production process.

Physical asset management (PAM) is an area with a growing role in the asset intensive industry. The purpose of this chapter is to emphasize the role of maintenance within PAM. For this purpose, a case study was conducted in a Slovenian organization. The results show that maintenance is recognized as part of PAM activities in the observed paper mill company. Furthermore, the results of the study show that the strongest involvement of maintenance in PAM-related tasks was found in the creation and maintenance of the maintenance management system and the least in the definition of key success factors for the asset system and the design of the asset system. In addition, the case study uncovered two main factors that have the greatest impact on the involvement of maintenance and its activities within PAM, namely leadership and knowledge management. This study is one of the few studies that aims to explore the role of maintenance within PAM, considering all life cycle phases of the asset system.

The number of studies that assess the level of maintenance in a country is still very small, despite the contribution of this area to national competitiveness. The literature analyses asset management based on key performance indicators, but not via a multicriteria model. This chapter describes a multicriteria model, constructed by means of the fuzzy analytic hierarchy process (FAHP). The weightings are converted into utility functions, allowing the final utility of an alternative to be calculated via a multi-attribute utility function. Data on the state of asset management in Spain, in 2005 and 2010, are used to produce discrete probability distributions. Finally, a Monte Carlo simulation is applied to estimate the uncertainty of a complex function. In this way, the level of excellence of asset management in small businesses in Spain, before and after the recession, could be determined. The results show that the economic crisis experienced in Spain since 2008 has had a negative effect on the level of asset management in most sectors.

This chapter uses a semi-Markov process and the z transform to find the optimal preventive maintenance interval when dealing with maintenance decision making for a finite time planning horizon. The result is a method that can be easily implemented to assets for which a Weibull reliability analysis exists. The suggested preventive interval formulation is simple and practical. The requirements to apply this simple formula are related to the existence of asset´s reliability data as well as cost/rewards that the assets have when remaining or transitioning to a given state. The application of this method can be very straightforward, and the tool can become a good decision support tool allowing “what if” analysis for different time horizon and maintenance policies.
