A model predictive control framework for advanced planning and scheduling in process industries

This paper presents a model predictive control (MPC) formulation for the planning and scheduling problem in process industries. The main idea is to use a moving horizon technique as well as a feedback control concept to continuously update production schedules and plans. In existing planning and scheduling formulations, a mixed integer (non)linear programming is very often solved over a chosen ...

Multitask and Multistage Production Planning and Scheduling for Process Industries

We consider the planning and scheduling of production in a multitask/multistage batch manufacturing process typical of industries such as chemical manufacturing, food processing, and oil refining. We allow instances in which multiple sequences of tasks may be used to produce end products. We formulate the problem as a mixed-integer linear program and show that the linear programming relaxation ...
