“…Cluster analysis is based on the assumption that homogenous information is available in raw data. The literature on cluster analysis can be found in studies such as Al-Omary and Jamil 2006, Ang (2000), Bowers et al (1995), Cheng et al 1995, Han and Ham (1986), King (1980), Rajagopalan and Batra (1975) and Vannelli and Kumar (1986). The technique clusters analogous objects based on information that is available from the existing production system (Bowers et al, 1995;Chow and Hawaleshka, 1992;Kusiak, 1990; Kusiak and Chow, 1987;Miltenburg and Zhang, 1991).…”

Group technology has been studied extensively from an 'industrial engineering' perspective (layout, scheduling, workflow, etc.), but less often from an organisational design viewpoint. To study this implication of group technology, the approach of applied systems theory for the design of organisational structures as framework for analysis was used in three empirical cases. To increase the reliability of findings from the analysis of these three empirical cases, five more cases were drawn from archival search. Cluster analysis and product flow analysis were the methods used for forming groups of machines and employees in manufacturing cells, whereas the coding of parts was not employed to this end. Furthermore, the results indicate that the implementation of group technology generally meets shifts in performance requirements caused by competitive pressures, particularly flexibility and responsiveness, albeit the companies considered group technology only when under pressure of 'poor' business performance. However, group technology is not always a solution to challenges that companies experience; one empirical case shows that defunctionalisation and scheduling with virtual groups was more beneficial. Nevertheless, when the introduction of group technology is feasible, it also allows firms to consider delegating responsibility for production planning and scheduling to lower levels in the hierarchy and semi-autonomous groups as an alternative to 'complex' software applications (a socio-technical approach). Whereas the current study sheds some light on the relationship between group technology and design of organisational structures, further research is necessary into the design of these structures and their relationship to group technology.

It is common knowledge that during the last decade markets have become extremely competitive with product variety increasing continuously and product life cycles shortening. Many manufacturing companies, which hitherto satisfied their customers while operating specific production systems, were recently obliged to reconsider because of the potential superiority of other “manufacturing philosophies”. In the literature, we meet a great variety of production systems and manufacturing philosophies, while, on the other side, in industry we usually find different combinations of “primary” productions systems. In this paper, we present the existing “state‐of‐the‐art” theoretical and experiential knowledge about productions systems, as well as describe their basic characteristics in a useful, exact and comprehensive way for practitioners and software houses who want to have a knowledge base for further research and practical implementation in the wider field of production management, planning and scheduling.

In Cellular manufacturing industries are producing similar products using cells, or groups of team members, workstations, or equipment, to make easy operations by eliminating setup and unnecessary costs between operations, Cells might be designed for a specific process, part, or a complete product. There is a strong propensity towards the effectiveness of manufacturing system, proper scheduling (determining the sequence of operations is to be performed) of jobs is essential for the flourishing operation of a shop. Group technology has become a more and more popular concept in manufacturing, which is designed to take advantage of mass production layout and techniques in smaller batch production system. Since the conventional scheduling methods need more computation time. In this paper, an effort has been made in two parts from the first part of this work is to optimize scheduling in different types of products in the job-shop environment are identified and grouping of cells is performed using Rank Order Clustering Method. In the second part, optimization procedure has been developed for the scheduling problem for processing in the machine cells. Particle Swarm Optimization and Genetic Algorithm are used in this paper for explore the optimum schedule by minimizing the total penalty cost due to the delay in meeting the due date. Better scheduling is obtained by comparing the two methods.
