Scheduling of heat integrated multipurpose batch Processes

A systematic mathematical framework for scheduling the operation of multipurpose batch plants involving heat-integrated unit operations is presented. The approach advocated takes direct account of the trade-offs between maximal exploitation of heat-integration and others scheduling objectives and constraints. In this paper, heat transfer takes place directly between the fluids undergoing processing in the heat integrated unit operations, and therefore a degree of time overlap of these operations must be ensured. The modelling is based on the ERTN formalism and a discrete time MILP formulation

Recipe-driven dynamic hybrid simulation of batch processes: a combined optimization/simulation approach

PrODHyS is a dynamic hybrid simulation environment dedicated to the modeling of devices and operations found in chemical processes. Unlike continuous processes, the dynamic simulation of batch processes requires the execution of control recipes in order to achieve a set of production orders. In this framework, this simulator is coupled to a scheduling module (ProSched) in order to initialize various parameters and to ensure a proper completion of the simulation. This paper focuses on the building procedure of the simulation model corresponding to the realization of a particular schedulin
