“…Brito and Almeida (2009), Alencar and de Almeida (2010) and Lins and de Almeida (2012) contextualize the multidimensional risk view in the context of natural and hydrogen gas pipelines. The multidimensional risk analysis results are presented by the risk difference between pipeline sections.…”

Abstract:Man's level of dependence on equipment is increasing. This degree of dependence requires high levels of availability, which has been changing the impact that disruption of these systems causes. For many systems, an interruption has consequences that go beyond the dimension of financial loss, thus justifying a multidimensional consequence approach by using multicriteria (MCDM/A) models. Thus, understanding the relationships between and among risk, reliability and maintenance (RRM) is essential in order to offer more comprehensive solutions to the various problems often treated in isolation from each other, and which are the most important problems of the competitive market. This chapter discusses fundamental topics about RRM, including tools for risk analysis and hazard identification, concepts of reliability, maintenance techniques such as RCM and TPM and eliciting expert's knowledge. These topics are presented in order to provide a basis for structuring different MCDM/A problems that are addressed in several chapters. Some fundamental aspects could be used as input to decision models in different forms such as attributes, objectives, criteria, and problem context. Basic Concepts on Risk AnalysisThere are many concepts on risk found in the literature and also different perceptions to it. However, if a decision is being made and risk is involved, then, the risk concept should combine consequences and probabilities, incorporating the DM's preferences over that, as seen in Chap. 2.Actually, a 'decision process' with no DM's preference has no decision being made, as discussed at the end of Chap. 1. Instead of that, that process either: a) has some preference structure incorporated within the model, at random; b) is just arbitrary following a previous decision of someone else.Even so, in most of real cases, the consequences are multidimensional, and therefore, require an MCDM/A approach for building a decision model. The following topics are mainly based on the basic RRM literature and do not incorporate the idea of decision support, as given in Chap. 2. That is, DM's preferences are not necessarily considered in the model.

“…The use of multicriteria methods is often in maintenance area in special when complex problems are highlighted in maintenance management systems [26,27]. Some examples these problems in maintenance area include risk evaluation [28,29], outsourcing and logistics [30], project management [31,32] and many others.…”

Abstract. This article presents a Decision Support System which focuses on an important organizational context: maintenance decisions. Usually, a specific management system is required to deal with data on failure, reliability, maintainability and availability regarding equipment. The maintenance context is surrounded by uncertainty and does not provide a clear profit from its activities, and thus requires a tool which fits in with organizational needs. The tool presented in this paper considers the requirements and approaches of an industrial production system, using concepts and methodologies from Reliability Centered Maintenance (RCM) to establish maintenance strategies, such as inspection and preventive maintenance planning, and also takes into consideration sophisticated MCDA and FMECA models for strategic decision making.

“…According to Alencar and Almeida [15], dividing the pipeline into sections is brought about by determining what the homogeneous features are that characterize a particular stretch of the pipeline. Age of piping, soil type, pressure, pipeline diameter and cathodic protection are some of the homogeneous features that should be considered.…”

“…Alencar & Almeida [15], Brito & Almeida [16], and Brito et al [30] expand this analysis to a threedimensional problem, which deals with human, environmental and financial dimensions. In this paper, the previous multicriteria approach found in the literature is further expanded, as per the hierarchical structure shown in Fig.…”

“…The model is based on MAUT (Multi-attribute utility theory) [14] and considers five dimensions of risk. The model proposed in this article is an evolution of previous studies on this matter [15,16], because it introduces new features, such as the disaggregation of the human and environmental dimensions into two new dimensions each, which makes the decision maker more aware of the problem. This allows more precision in the elicitation process, since each sub-dimension can be addressed directly and not as items aggregated implicitly.…”
