This paper presents a mixed integer nonlinear programming (MINLP) model for the change planning of spin pack in polyester filament plants. The model minimizes the total cost based on the cost of cleaning and the cost of operating and takes into account changes in production rates and even changes in the properties. This is important for the case of polyester filament production in the chemical fiber...
This paper addresses the problem of optimizing cyclic schedules in polyamide staple fiber plants. The problem concerns the scheduling of a production consist of two sequence of stages each involving one production line that are interconnected by intermediate warehouse. A mixed integer programming (MILP) model for cyclic schedules in polyamide staple fiber plants is formulated according to traveling...
