Abstract
Purpose
The purpose of this paper is to define a process for maintenance management and to classify maintenance engineering techniques within that process.
Design/methodology/approach
The paper presents a generic model proposed for maintenance management which integrates other models found in the literature for built and in‐use assets, and consists of eight sequential management building blocks. The different maintenance engineering techniques are playing a crucial role within each one of those eight management building blocks. Following this path it characterizes the “maintenance management framework”, i.e. the supporting structure of the management process.
Findings
The paper offers a practical vision of the set of activities composing each management block, and the result of the paper is a classification of the different maintenance engineering tools. The discussion of the different tools can also classify them as qualitative or quantitative. At the same time, some tools will be very analytical tools while others will be highly empirical. The paper also discusses the proper use of each tool or technique according to the volume of data/information available.
Practical implications
As a consequence, of the implementation of advanced manufacturing technologies and just‐in‐time production systems, the nature of the production environment has changed during the last two decades. This has allowed companies to massively produce products in a customized way. But the increase in automation and the reduction in buffers of inventory in the plants clearly put more pressure on the maintenance system. The present maintenance management framework has been proposed in order to diminish this pressure. Whatever the model an organization adopts, it has to be evolving to continue being useful against the fast changes that occur in business, communications and industry. A key to achieve this could be the incorporation of the techniques proposed in this paper besides the integration of platforms known as “next generation manufacturing practices” This implies the use of e‐maintenance as a sub‐concept of e‐manufacturing and e‐business.
Originality/value
This paper presents not only a process but also the framework and techniques to manage and improve maintenance effectiveness and efficiency. This paper will be useful to researchers, maintenance professionals and others concerned with maintenance management.

Abstract
Purpose
The purpose of this paper is to select the best maintenance policy for different types of equipment of a manufacturer integrating the fuzzy analytic hierarchy process (FAHP) and the technique for order of preference by similarity to ideal solution (TOPSIS) models.
Design/methodology/approach
The decision hierarchy of this research includes three levels. The first level aims to choose the best maintenance policy for different types of equipment of an acid manufacturer. These equipment pieces include molten sulfur ponds, boiler, absorption tower, cooling towers, converter, heat exchanger and sulfur fuel furnace. The second level includes decision criteria of added-value, risk level and the cost. Lastly, the third level comprises time-based maintenance (TBM), corrective maintenance (CM), shutdown maintenance and condition-based maintenance (CBM) as four maintenance policies.
Findings
The best maintenance policy for different types of equipment of a manufacturer is the main finding of this research. Based on the obtained results, CBM policy is suggested for absorption tower, boiler, cooling tower and molten sulfur ponds, TBM policy is suggested for converters and heat exchanger and CM policy is suggested for a sulfur fuel furnace.
Originality/value
This research develops a novel model by integrating FAHP and an interval TOPSIS with concurrent consideration of added-value, risk level and cost to select the best maintenance policy. According to the highlights of the previous studies conducted on maintenance policy selection and related tools and techniques, an operative integrated approach to combine risk, added-value and cost with integrated fuzzy models is not developed yet. The majority of the previous studies have considered classic fuzzy approaches such as FAHP, FANP, Fuzzy TOPSIS, etc., which are not completely capable to reflect the decision makers’ viewpoints.

Abstract
Purpose
In this paper, the authors are concerned with a maintenance workshop (MW) centralizing all corrective maintenance activities. The purpose of this paper is to propose a methodology for designing a central maintenance workshop, enabling the evaluation of performance in terms of cost and sojourn time, for a given budget.
Design/methodology/approach
The authors propose a modeling framework based on queuing networks. The aim is to maximize operational availability of the production workshop, by reducing the sojourn time of failed equipment in the MW.
Findings
The proposed methodology leads to a maintenance decision support tool enabling to give the structure of the MW, performing at a higher level, but at a reasonable configuration cost. Simulation results illustrate the influence of different parameters, such as the number of stations and the level of spare parts in the MW, on the sojourn time of the equipment.
Research limitations/implications
Only corrective maintenance is taken into account and only equipment that can be taken out of the production workshop are considered. The preventive replacement of some equipment items can be taken into account by the repair process by considering them as failed.
Originality/value
The work falls within a more general framework for optimizing maintenance costs, in the context of integration of multi-site services in a distributed context. The paper is concerned with centralized maintenance, and proposes to integrate the so-called repair by replacement technique in a MW, used for a multi-site production workshop.

The paper proposes a maturity assessment method to measure the state of maintenance practices in a company.
Abstract
Purpose
The paper proposes a maturity assessment method to measure the state of maintenance practices in a company.
Design/methodology/approach
The method assumes that a maintenance department is evaluated in terms of its managerial, organizational and technological capabilities. By its adoption it is possible to analyse the maturity level reached by a company, in order to classify the criticalities in its maintenance processes; a company can also make a benchmark with the best companies of a reference sample.
Findings
The paper presents the method as a support to identify the levers to improve the maintenance management system. The method is demonstrated on a company whose maturity is assessed before making a benchmark against a sample of other manufacturing companies located in the Northern Italy.
Originality/value
The paper presents a scoring method for maturity assessment and a procedure to use it in order to identify the criticalities in maintenance processes and to subsequently drive the improvement of the maintenance management system. The paper should be useful both to researchers and maintenance professionals interested in using new methods for long‐term planning in maintenance.

Abstract
Purpose
This paper aims to propose a methodology to assist manufacturing companies in the implementation of condition-based maintenance (CBM) to their equipment. The developed methodology intends to consider the use of sensors already installed on the equipment and, when required, to support the selection of sensors available on the market. Since CBM using sensors is not always feasible, the information gathered for the feasibility study of CBM implementation is also used to assign other maintenance strategies.
Design/methodology/approach
Based on the literature review, requirements and specifications were established for endowing the methodology with relevant and distinctive characteristics. The structure of the methodology and the associated steps were defined based on this information. Then, the methodology was validated and refined using a case study.
Findings
In the case study company, following the methodology and the respective steps, appropriate maintenance strategies were assigned to a selected manufacturing machine, considering information related to the failure modes with the most significant impact, and CBM was applied to a selected component for which the benefit outweighs the costs involved, using data acquired by sensors subsequently installed on the analyzed machine.
Practical implications
Due to its comprehensiveness, this methodology can contribute to make CBM implementation accessible to a high number of companies and encourage the application of a wide variety of monitoring techniques.
Originality/value
This new methodology can be easily integrated into a computerized maintenance management system and has the advantage of facilitating the collection, organization and standardization of technical knowledge required to support CBM implementation and define the most appropriate maintenance strategy systematically and automatically. It guides the prioritization of equipment and failure modes, and the decision-making regarding the selection of sensors and the allocation of maintenance strategies with the aim of reducing costs.

Abstract
This chapter reflects upon the trajectory of research in the geography of tourism in Spain. It begins with a review, including the evolution of the main topics present in the subdiscipline, with a special focus on developments since the 1990s. This is followed by an analysis of the current role and potential impact of academic tourism geography and a discussion on the recent growth in the publication of research results in international journals. Of importance are the institutional factors that explain the increasing recognition of research on the geography of tourism in Spain. Finally, the chapter discusses the hegemony of positivist approaches pivoting on land use, local and regional development, impact analysis, and landscape transformation, as well as the emerging links between Spanish tourism geography and the international mainstream schools of thought.

Abstract
Despite the boom corporate social responsibility (CSR) and sustainability are enjoying nowadays in the agendas of both small and big companies, we still have difficulties in providing a clear definition of the concept of sustainability. There is no consensus on the criteria to be used to define and enhance responsible management that creates sustainable development.
After a systematic revision of the literature, authors have been mapping the limits of the research already done at different levels, dimensions, and horizons, so we do have a 360° map of the research on sustainability. Future developments are also explored to enrich and align the diverse approaches demanded to define this wide, complex, and by now, equivocal concept and the conclusions reveal the many gaps not yet covered in the research field, signposting key issues for further work.
