Preface

Maintenance is a critical variable in industry to achieve competitiveness. Therefore, correct management of corrective, predictive, and preventive politics in any industry is required. *Maintenance Management* considers the main concepts, state of the art, advances, and case studies in this topic. This book complements other subdisciplines such as economics, finance, marketing, decision and risk analysis, engineering, etc.

The book analyzes real case studies in multiple disciplines. It considers the topics of failure detection and diagnosis, fault trees, and subdisciplines (e.g. FMECA, FMEA, etc.). It is essential to link these topics with finance, scheduling, resources, downtime, etc. to increase productivity, profitability, maintainability, reliability, safety, and availability, and reduce costs and downtime.

This book presents important advances in mathematics, models, computational techniques, dynamic analysis, etc., which are all employed in maintenance management.

Computational techniques, dynamic analysis, probabilistic methods, and mathematical optimization techniques are expertly blended to support the analysis of multicriteria decision-making problems with defined constraints and requirements.

The book is ideal for graduate students and professionals in industrial engineering, business administration, industrial organization, operations management, applied microeconomics, and the decisions sciences, either studying maintenance or who are required to solve large, specific, and complex maintenance management problems as part of their jobs. The book will also be of interest to researchers from academia.

The editors are very grateful to all the authors who have contributed to this book.

The industry requires maintenance to ensure the correct operations of the engines, components, structures, etc. [1] Any failure, that is, termination of the ability of an item to perform a required function, generates downtimes, costs, risks for the human labors, etc. The high competitiveness in the current industry does not

The advances in information and communication systems, together with the technologies, lead to the industry to incorporate new sensors, condition monitoring systems, etc. [3] They also require advance analytics in order to format, save, and analyze these signals and information, from qualitatively and quantitative point of

In order to reduce the failures occurrence probability, a correct maintenance task is required. British Standard, BS EN-13306:2017 [5] defines maintenance as "managerial actions during the life cycle of an item intended to retain it in, or restore it to, a state in which it can perform the required function. Technical maintenance actions include observation and analyses of the item state (e.g., inspection, monitoring, testing, diagnosis, prognosis, etc.) and active maintenance actions (e.g., repair, refurbishment)." The correct maintenance support to a maintenance organization to carry out the correct tasks is called maintenance

There are a large number of maintenance types, where the principal could be:

• **Corrective maintenance**, is the most common type, is done when the failure appears. In case, if it is delayed, it is defined as deferred corrective maintenance; in other case, it is called as immediate corrective maintenance.

• **Preventive maintenance**, done in certain times or according to criteria to reduce the failure probability [6]. Predetermined maintenance is set according to intervals of times or use of the item. Scheduled maintenance is done as predetermined maintenance or in a time schedule established previously. Condition-based maintenance is carried out regarding to the item status that is

• **Predictive maintenance**, the maintenance tasks are done according to the item
