BATCHSPC is a computer interface designed for the application of the models developed by Kocis and Grossmann (1988) and Voudouris and Grossmann (1992) for the optimal design of multiproduct batch plants. The plant consist of M processing stages where fixed amounts Q of N products must be manufactured. The design problem consists of finding the number of parallel units per stage, their sizes and for each product the batch sizes and cycle times that correspond to the minimum investment costs.

BATCHSPC considers two cases for the unit sizes:

1. Continuous sizes model (MINLP).
2. Standard sizes model (MILP).

Both cases assume the following :

1. Single product campaigns.
2. Batch processing time is independent of batch sizes

BATCHSPC has been developed by Gabriela Garcia-Ayala under the supervision of Ignacio E.Grossmann and is based on the papers by Voudouris & Grossmann, "Optimal Synthesis of Multiproduct Batch Plants with Cyclic Scheduling and Inventory Considerations", I&EC Research,32, 1962-1980 (1993); and by Kocis and Grossmann, "Global Optimization of Nonconvex MINLP Problems un Process Synthesis", Ind. Eng. Chem. Research, 27, 1407 (1988).
