A Design and Scheduling RTN Continuous-time Formulation

摘要

This paper presents a general mathematical formulation for the simultaneous design and scheduling of multipurpose plants. The formulation is based on the Resource Task Network process representation, uses a periodic, uniform time grid, continuous-time representation and originates mixed integer nonlinear programs (MINLPs) or mixed integer linear programs (MILPs), depending on the type of tasks and objective function being considered. Its performance is illustrated through the solution of two batch-plant example problems that have been examined in the literature.
