The Threshold Value Of A Quality Index For Formation Of Cellular Manufacturing Systems, Hamid Seifoddini, Manocher Djassemi
The Threshold Value Of A Quality Index For Formation Of Cellular Manufacturing Systems, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
The superiority of cellular manufacturing to job shop manufacturing has been questioned by a number of simulation studies. The initial structure of the machine-part matrix seems to play an important role in the failure of cellular manufacturing systems in these studies. In this paper a grouping measure called 'quality index - QI' will be used to evaluate the relationship between the quality of a machine-part matrix and the performance of the corresponding cellular manufacturing system. A simulation study will be conducted to demonstrate how the procedure can be used to determine the threshold value for QI beyond which the cellular …

Sensitivity Analysis In Cellular Manufacturing System In The Case Of Product Mix Variation, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
In this paper, performance measures such as mean flow time and work-in-process inventories will be used to determine the changes in the performance of a cellular manufacturing system due to product mix variations.
Improving The Performance Of Cellular Manufacturing By A Dynamic Part Assignment Approach, Hamid Seifoddini, Manocher Djassemi
Improving The Performance Of Cellular Manufacturing By A Dynamic Part Assignment Approach, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
In this paper, a simple dynamic part assignment (DPA) procedure is introduced and its effects on the performance of cellular manufacturing systems is evaluated. In this procedure rerouting of parts among machine cells is allowed for better machine utilization. Three data sets are used to compare the performance of manufacturing systems under job shop and cellular manufacturing when DPA is employed. The results of simulation runs indicate that the proposed DPA method improves the performance of cellular manufacturing significantly by reducing the congestion in machine cells with long waiting lines.
A New Grouping Measure For Evaluation Of Machine-Component Matrices, Hamid Seifoddini, Manocher Djassemi
A New Grouping Measure For Evaluation Of Machine-Component Matrices, Hamid Seifoddini, Manocher Djassemi
Industrial Technology and Packaging
The machine-component matrix is the main input to most machine-component grouping models used in cellular manufacturing. A number of measures have been developed for performance evaluation of machine-component grouping algorithms. In this paper, the relationship between these measures and the performance of the corresponding cellular manufacturing system is evaluated and a new grouping measure is developed which is more consistent in predicting the suitability of a manufacturing system for cellular manufacturing.
