The changes in manufacturing systems and industrial structure brought about by the development of new, computer-based flexible technologies has been a subject of growing debate during the last decade. There is a lack of solid empirical support for almost all hypotheses developed in this debate since data on the relative use of various manufacturing systems are not available for an econometric a...

In recent times flexible manufacturing systems emerged as a powerful technology to meet the continuous changing customer demands. Increase in the performance of flexible manufacturing systems is expected as a result of integration of the shop floor activities such as machine and vehicle scheduling. The authors made an attempt to integrate machine and vehicle scheduling with an objective to mini...

Facing new challenges and more uncertainty, manufacturers see the need for flexible solutions and the need to strive to achieve flexibility. However, flexibility is still not well understood and no unambiguous understanding of flexibility exists. The paper first summarizes the state of the field of flexibility, exploring different definitions and understandings of the flexibility concept from t...

The task of scheduling in flexible manufacturing systems (FMS) is more complex and problematic than a traditional manufacturing systems. To accomplish great performance for FMS, a good scheduling system should make an accurate decision at an accurate time according to system situations. Fuzzy logic methodologies easily deal with indeterminate and incomplete information. Human expert‟s knowledge...

Paradigms in modern production are shifting and pose new demands for optimization techniques. The emergence of new, versatile, reconfigurable and networked machines enables flexible manufacturing scenarios which require, in particular, planning and scheduling methods for cyber-physical production systems to be flexible, reasonably fast, and anytime. This paper presents an approach to flexible j...

Flexible Automation as a topic of research has been around for at least a half century. In the late 70’s, flexible manufacturing cell/systems (MFC/MFS) started playing pivotal roles in modern industry, in particular automobile industry. However, the journey of going from a theory or vision to an art or reality did not end there and then. In the last two decades, flexible automation has taken on...

Scheduling of production in Flexible Manufacturing Systems (FMSs) has been extensively investigated over the past years and it continues to attract the interest of both academic researchers and practitioners. The generation of new and modified production schedules is becoming a necessity in today’s complex manufacturing environment. Genetic algorithms are used in this paper to obtain an initial...

A number of manufacturing systems are categorized into Cell-Based Manufacturing Systems (CBMSs), which have similar physical configurations typically composed of manufacturing cells, transporters and their controllers. However, since the control modules are not separable from the model in conventional simulation frameworks, it is difficult to develop a generic high-fidelity simulator for CBMSs ...

It is shown that a large class of flexible manufacturing cells can be modeled using timed Petri nets. Net models of simple schedules (i.e., schedules in which exactly one part enter and one leaves the cell during each cycle) are conflict–free nets. Invariant analysis of such models provides analytic (or symbolic) solutions for the cycle time or throughput of a cell. Several directions for furth...
