Abstract
The control of conveyor to support the operations of machine loading and unloading has become rebellious and crucial to the management. However, through the mathematical model proposed in this paper, this issue becomes realistically and concretely solvable. This study not only meditates the conception of balancing the number of parallel machines and adjusting conveyor speed into the objective, but also develops a heuristic method to optimize the combinatorial problem for maximizing profit. In addition, the versatility of this study is exemplified through a numerical study. This paper definitely contributes an applicable scheme for production scheduling in manufacturing and provides a valuable tool to conclusively optimize the profit of a given production lot size for operations research engineers in today’s manufacturing with profound insight.
