The Product Oriented Manufacturing (POM) concept here presented addresses competition in today’s changing global market of manufacturing companies. It is a challenge to the Function Oriented Manufacturing (FOM) concept supposedly adequate for dealing with demand changes and large product variety without needing reconfiguration. The POM concept evolves from the traditional cellular manufacturing...

Group technology (GT) is a useful way to increase productivity with high quality in flexible manufacturing systems. Cell formation (CF) is a key step in GT. It is used to design a good cellular manufacturing system that uses the similarity measure between parts and machines so that it can identify part families and machine groups. Recently, fuzzy clustering has been applied in GT because the fu...

There are essentially two ways to implement a Cellular Manufacturing System (CMS): physical and logical. In the first case, the machines are laid out in the floor space in dedicated manufacturing cells to exploit flow shop efficiency in processing part families, whereas in the second case machines are dedicated to process part families in a process layout. Logical oriented CMS are known as Virt...

This paper deals with the transient analysis of manufacturing systems in the presence of failures and repairs. The exact model is decomposed into 1) a structure state process, modeling the failure and repair events which occur at a slower time scale, and 2) a performance model, modeling the part processing and material movement events occurring at a faster time scale. The solutions of these two...

We compare two approaches for a Markovian model in flexible manufacturing systems (FMSs) using Monte Carlo simulation. The model which is a development of Fazlollahtabar and Saidi-Mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (AGV) namely, the reliability of machines and the reliability of AGVs in a multiple AGV jobsho...

Cellular manufacturing is a promising approach for grouping eeciency in manufacturing systems. Although this problem has been extensively studied in the literature, very few authors have proposed exact methods. The basic cellular manufacturing problem consists in deening cells which lead to the minimum number of bottleneck elements. In this paper, we consider a new formulation of the cellular m...

  This paper deals with the cellular manufacturing system (CMS) that is based on group technology concepts. CMS is defined as identifying the similar parts that are processed on the same machines and then grouping them as a cell. The most proposed models for solving CMS are focused on cell formation problem while machine layout is considered in few papers. This paper addresses a mathematical mo...

Nowadays, in highly competitive global markets and constant pressure to reduce total costs, enterprises consider group technology and Supply Chain Management (SCM) accordingly and usually separately as the key elements for intra and inter facilities improvement. Simultaneous consideration of the elements of these two disciplines in an integrated design can result in higher efficiency and ...

this article addresses a single row facility layout problem where the objective is to optimize the arrangement of some rectangular facilities with different dimensions on a line. regarding the np-hard nature of the considered problem, a hybrid meta-heuristic algorithm based on simulated annealing has been proposed to obtain a near optimal solution. a number of test problems are randomly generat...
