Despite many manufacturers possessing multi-million pound spare parts inventories, little research or analysis has considered how these spares may be better managed and controlled in a practical approach. This is largely because spare parts inventories are notoriously difficult to manage, due to variable and unpredictable demand, erratic lead-times for replenishment and difficulties in determining stockout costs (Sandvig and Allaire, 1998). In this paper, we briefly discuss the maintenance problem. We then examine the role of CMMSs as an aid to address the different challenges facing maintenance especially in terms of management, current deficiencies and spare parts inventories. We focus our investigation on problems with maintenance inventory in terms of conflicting objectives and its unique characteristics. We extend our review to inventory policies and how they relate to maintenance inventory control.

It presents definitions of MS concepts from a set of selective references and works, which have influenced on and led to development of the present RMS paradigm. To understand the evolution of MSs aimed at reconfigurability and the position of RMS among conventional MSs, the chapter commences by reviewing industrial revolutions and various types of production systems. Flexible manufacturing systems (FMSs), cellular manufacturing systems (CMSs), agile manufacturing systems (AMSs) and virtual cellular manufacturing systems (VCMS) are described with focusing on the concept, design and modelling aspects. In addition, the need to develop new methodologies aimed at greater flexibility through reconfigurability of MSs is presented.

Because of risk and uncertainty in an RMS environment, this major task must be performed precisely before investment in its detailed design. The feasibility study is not only intended to evaluate the possibility of implementation of an RMS design but also to produce a reference base for its evaluation through the design loop over planning horizons. The RMS key feature of reconfigurability is described as its operational feasibility to deal with capacity changes and functionality, which are considered as the major attributes for feasibility evaluation. An integrated structure of the Analytical Hierarchy Process (AHP) and fuzzy set theory is presented. The fuzzy Analytical Hierarchy Process (FAHP) model is examined in an industrial case study.

In this book the problems of theory and practice of development in Reconfigurable Manufacturing Systems and Transformable Factories for various machine-building branches and above all automotive industry are discussed. Problems are studied concerning the development of a new class of production systems which in comparison to the Flexible Manufacturing systems are composed of a far less quantity of machine-tools. In comparison to the conventional automated lines they make it possible to rapidly transform the equipment for new products manufacturing. In 37 chapters more then 50 authors from all over the world discuss the main aspects of the mentioned above problem using their latest scientific and practical achievements.

The intention is to carry out further research in this field. The objectives of the extended research are: i) to investigate the effectiveness of using fuzzy logic in a complex decision-making capacity, in particular, for the prioritisation of kidney transplant recipients and to compare and contrast the performance of a scheme based on fuzzy logic with the actual Kidney Allocation Scheme, ii) to contrast it with another representation and reasoning mechanism applied in the USA based on Multiple Criteria Decision Making (MCDM) techniques, and iii) to develop a self-adaptive feedback model for adjustment of the decision makers' consistency of judgements when setting priorities. Despite the medical research carried out, this paper does not pretend to be an authority on medical decisions. The models can al...

Failure analysis is the basic work in reliability analysis. So far, there is little in-depth and meticulous study about failure of the tool magazine and ATC, but there are many problems in the use of tool magazine and ATC. Based on the failure data received from field tracing tests, the failure modes, effects, and criticality analysis of the studied circular tool magazine and ATC are evaluated. The failure positions, causes, and criticalities in circular tool magazine and ATC, which have the highest criticality parameters are explored, offering the basis for the improvement in the design of the new products.

The work presented to students requires the integration of the motion of an industrial robot (ASEA IRB 6) with a camera vision system (Baxall CD9752); they are asked to develop software that will support: the motion of the robot arm, including forward and reverse kinematics; the detection of an object on a test table; the picking up of the object; and its move to a target position on another test table. To assess the experiment, students select seven random points in the active camera area to determine the difference between the actual location of the end-effector and the location calculated using two methods: the trigonometric solutions and the DH parameters. Students discover that the trigonometric technique gives better position accuracy than DH. The project forms an excellent practical exercise to enhance student learning.
