Optimal Cyclic Control Of A Buffer Between Two Consecutive Non-Synchronized Manufacturing Processes, Wenhuan Hsieh
Optimal Cyclic Control Of A Buffer Between Two Consecutive Non-Synchronized Manufacturing Processes, Wenhuan Hsieh
Theses and Dissertations
This thesis presents methods for efficiently controlling a buffer that is located between two non-synchronized manufacturing processes. Several machines with different cycle times and/or batch sizes perform each manufacturing process. The overall operation cycles every T time units. The first objective of the problem is to minimize the average buffer inventory level during one cycle. The second objective is to minimize the maximum inventory level observed at any point during the cycle. This new optimization problem has not been previously considered in the literature. An integer program is developed to model this problem. In addition, two heuristic methods—a simulated annealing …
