We consider a flexible manufacturing facility that can be operated in any of m different modes. While running in mode k certain intermediate products are consumed and other intermediate or finished products are created. There may be variability in the manufacturing process, as well as random arrivals of raw materials and orders for finished products. We establish conditions that ensure demands ...

One of the major problems confronting the search for efficiency in flexible manufacturing systems is the problem of loading and scheduling. This abstract presents a new method to solve such problems. The methodology, which is based on the use of genetic algorithms, allows simple codification of problems and thus facilitates its use. Two kinds of solution are proposed – that is, loading and sche...

this article is arranged based on a research plan which its goals is evaluation of the possibility of applying flexible human resource structure in industrial organizations. in this research, applying conditions of just in time (j.i.t) and flexible manufacturing systems (f.m.s) have brought up as a pioneer flexible movements in industrial units and based on based two phenomenon, the nescessity ...

A computer simulation system, which is based-siphon Petri net for control of concurrent processes of the reusable resources, that is mainly aimed to provide guidelines for control and management engineering of flexible manufacturing systems (FMSs) is presented in this work. We present an important technique for the analysis of siphon Petri net (PN) based on structural analysis, control, and sim...

This paper presents a framework for the determination of an efficient level of simulation model fidelity for flexible manufacturing systems, which will achieve acceptable output accuracy with minimum resources and thereby reduce model building effort and computation time. To this end, we first formally define different levels of model fidelity using building blocks available in object–oriented ...
