Machine Cell Formation with Sequence Data for Cellular and Automated Manufacturing Systems

摘要

Production sequence and product volumes, if incorporated properly in determining the machine cells in the cellular and automated manufacturing systems, can enhance the quality of solutions and reduce the number of intercellular moves and material handling cost. Thus, the number of trips between a pair of machines from a part type should be incorporated in the determination of similarity for respective pairs of machines. Measures for cell formation based on operations sequence utilizing ordinal data are few and have many limitations. Also they count the number of the trips for each individual part instead of counting the weights of the batches. A new similarity measure based on the sequence of operations parameter and the batch size of the parts are introduced. The new similarity measure showed more sensitivity to the intercellular moves and better machine grouping.
