Über dieses Buch

The management of technical plants for productivity and safety is generally a complex activity, particularly when many plants in one territory are affected, quality guarantees and cost results are required, and the technology involved is heterogeneous and innovative. To enable readers to manage technical plants efficiently, despite the above complications, Methodologies and Techniques for Advanced Maintenance presents theories, methodologies and practical tools for the realization of an intelligent maintenance management system for distant monitoring. It also covers the development and running of a remote control center. The so-called granted availability management system (GrAMS) was conceived to enable organizations involved in technical-industrial plant management to move towards “well known availability” and “zero failures” management. In particular, Methodologies and Techniques for Advanced Maintenance deals with the diagnostic aspects and safety levels of technical plants (such as elevators, thermo-technical plants, etc.). The author also discusses the usage of ad hoc designed software analysis tools based on neural networks and reliability indicators. Methodologies and Techniques for Advanced Maintenance is a useful text for practitioners and researchers in maintenance and facilities. Its application spans industrial, plant, technological, infrastructure and civil fields.

BASIC MAINTENANCE

Chapter 1. Introduction
Abstract
What does maintenance mean and what is the etymology of the word? Has the original meaning changed, or has it evolved throughout man’s history and, in particular, in recent years? How can maintenance be placed, historically, with respect to other technical and scientific disciplines? What has made maintenance a subject of growing interest in recent years?
Lorenzo Fedele
Chapter 2. Planning and Managing Maintenance
Abstract
The analysis of post-industrial society brings out the spread of attention towards social phenomena that imply increasingly greater spaces for the dimension of maintenance. We refer in this connection to:
  • the transversal nature of many aspects and components of development;
  • a strong characterisation of economic and social transformation, in terms of continuous technological innovation;
  • the pervasive nature of innovation, in both social and technological terms;
  • the expansion of tertiary productive activities, which have reached the level of the services economy itself.

Chapter 3. The Life Cycle of Products and Systems and Logistical Engineering
Abstract
During the phase of planning of a system, situations often occur in which the complexity of models of dependability and the number of parameters in play create a very complex framework, in which it would be almost impossible to make any decision relative to system choices, technologies, initial component quality and engineering, etc. in the absence of in-depth analysis conducted with appropriate methods of research.
Lorenzo Fedele
Chapter 4. Maintenance Policies and Strategies
Abstract
In this chapter we will analyse the various strategies that we have referred to above, on the basis of an important premise: it is quite easy to have a certain degree of confusion in identifying the various approaches to maintenance, because the diversities that authors attempt to bring to light are often fuzzy and difficult to render in a complete manner and, at times, through translations. In any case, the declared intention of this treatise is not to clarify possible shortfalls relative to terminology, but to provide an overview of the various possible approaches to maintenance, highlighting as much as possible the interrelations and stages that have marked its development.

ADVANCED MAINTENANCE

Chapter 5. From Basic Maintenance to Advanced Maintenance
Abstract
Condition monitoring is the activity of evaluating the current condition of a plant or apparatus, obtained through techniques that range from the use of complex computerised instruments to the exploitation of human sensitiveness, for the purpose of preventing breakdowns and implementing maintenance only in the presence of a potential breakdown and when it is most convenient on the basis of the production schedule (Williams et al. 1994).
Lorenzo Fedele
Chapter 6. Testability and Prognostics
Abstract
With a view to maintenance, the concept of system testability is understood as the ‘intrinsic characteristic of a system or apparatus to permit means of internal self-diagnosis, or appropriate external instrumentation, to verify the functional efficiency and diagnose breakdowns'. This logistical parameter has been a matter of concern for some time now, and many figures of merit (FOM) have been defined for it in order to evaluate the quality of a system of self-diagnosis or to estimate how testable an apparatus is from outside.

CASE STUDIES

Chapter 7. Intelligent Telematic Maintenance Systems for the Management of Technical Plants (by Lorenzo Fedele and Giampiero Mercuri)
Abstract
The management of technical production and safety plants is generally a complex activity, especially when the management of a great many plants distributed throughout the territory is required (for example, the increasingly frequent case of entrusting the maintenance of plants to specialised outsourcers), when a guarantee of the quality and results is required (such as in the case of several innovative contractual solutions) and when the technology of the plants is heterogeneous and innovative (for example, in electro-mechanical plants, etc.).

Chapter 8. Model for the Overall Evaluation of Management and Maintenance Contracts (by Lorenzo Fedele and Massimo Concetti)
Abstract
The investigation conducted on the state of the art was performed through analysis of the most important instruments available in the literature and practice for the measurement of quality in services, especially focused on the extension of these approaches to the management of quality in the field of maintenance services. This also referred in particular to cases where these services are entrusted to third parties through global service contracts.

Chapter 9. The System of Unified Diagnostics and Standard Maintenance of Bridges and Infrastructures
Abstract
In the sector of structural concrete constructions, these themes have been the subject of systematisation by the European Beton Committee, stimulated by the widespread state of deterioration of structures in Europe after the Second World War, especially bridges and parking lots. Testimony to the condition of deterioration of these structures can be found in the acts of international congresses: in 1975, the “Colloquium Inter Association IABSE–FIP–CEB–RILEM–IASS Behaviour in Service of Concrete Structures” held in Liegi; in 1980, one of the themes of the “1st International Congress of the Association for Bridge and Structural Engineering (IABSE)” held in Vienna was “Lessons from the Behaviour of Structures”; in 1988, one of the themes of the 13th IABSE Congress, held in Helsinki, examined “Inspection, Assessment and Maintenance”; in 1992, one of the themes of the 14th IABSE Congress, held in New Delhi, concerned “Bridge Management Systems”. One of the contributions to this theme, “A Decision System for Bridge Management”, by J. De Brito and F. A. Branco, of the Technical University of Lisbon, confirms the high percentage of deterioration observed in reinforced concrete and pre-compressed reinforced concrete bridges, in recent decades, proposing a decision-making system based on the data collected from three levels of inspection: current inspection, based almost exclusively on visual observation, detailed inspection, integrated by non-destructive on-site tests, and ascertainment of the structural conditions of the works. These analyses proved to be the elements in determining an index of evaluation, used to decide upon any corrective intervention within the ambit of maintenance procedures and, if necessary, to make repairs or provide for reinforcement.
