Scheduling in reconfigurable manufacturing system for uncertainty in decision variables

What is it about?

In the present work, an integrated approach of Shannon entropy and multi-attribute range evaluation (MARE) has been used for scheduling of the products. Weights of criteria have been calculated using Shannon entropy and ranking is obtained using MARE. MARE calculates the uncertainty of decision variables into the uncertainty of ranking. For scheduling of products, three criteria have been considered; reconfiguration effort, profit over cost and due date.

Why is it important?

Scheduling is the one of the most important steps in production control. Scheduling is concerned with when work shall be performed on a product or part. Scheduling in manufacturing system can be done on the basis of some rules. It can be done for one criterion as mentioned above or more than one criterion. For scheduling of products, three criteria have been considered; reconfiguration effort, profit over cost and due date. An integrated approach of Shannon entropy and multi-attribute range evaluation (MARE) has been used for scheduling of the products. Weights of criteria have been calculated using Shannon entropy and ranking is obtained using MARE. MARE calculates the uncertainty of decision variables into the uncertainty of ranking.
