Advanced production scheduling for batch plants in process

Chemical Production Scheduling – Maravelias Group – …

In chemical production scheduling, we seek to allocate limited resources to competing tasks over time. The key decisions include the selection and sizing of tasks (batches), the assignment of tasks to equipment units, and the timing of tasks. Production planning and scheduling problems arise in many areas, from basic chemicals and consumer

New MILP Models for Scheduling of Multiproduct Batch

Oct 08, 1996 · This paper presents a new mixed-integer linear programming (MILP) model in which makespan is minimized for the multiproduct batch plants. In particular, the zero-wait (ZW) scheduling with transfer and setup times is analyzed. Not only idle times between the successive products but also heads and tails are used to select a possible production sequence with the minimum makespan. To …

Batching and Scheduling Jobs on Batch and Discrete

Dec 27, 2017 · Each batch processor can process a batch (limited number) of jobs simultaneously. Once the process begins, no job can be released from the batch processor until the entire batch is processed. In this paper, we analyze a class of two-machine batching and scheduling problems in which the batch processor plays an important role.

An MILP Model for Short Term Scheduling of a Special Class

sequential multipurpose batch plant. In particular, the scheduling problems of the multipurpose batch plants under MPC are addressed here. An MILP model is developed based on a time slot, which is used to determine the production sequence and to select the production path for each batch of product. Every batch of product is assigned to a time slot.
