Collaborative Production Planning in Multi-Plant Feed Mill Industry

Abstract:

In animal feed production, there are several feed products to be processed through mixer and pelleting machines. To avoid the contamination between two feed products, machines are required to be cleaned (i.e., machine setup) when switching production between different feed products. The cleaning process lessens the machine capacity. In this paper, the production planning based on the collaboration between two feed plants is studied in order to reduce unnecessary machine setup time. The problem is to optimally allocate products to be processed in each plant with suitable production lot size. The trade-off between inter-plant transferring cost and the setup cost is considered. The mathematical model is developed and solved with small size problems. The results indicate that the collaborative plan provides the better plan with the cost 16.05% less than the non-collaborative production plan.
