About this site

Jan 01, 1998  A convex MINLP model for the preliminary design problem of a multi-product batch plant is developed. The plant model consists of several batch and semicontinuous stages. The parallel units on a batch stage can be operated in-and/or out-of-phase while all units on a semicontinuous stage are operated in-phase.
