 In this paper, a general multiperiod nonlinear optimization model is presented, which incorporates synthesis, design and operation, and takes into account the corresponding benefits and costs in each time period. The model is formulated as a non linear programming (NLP) model in which plant structure decisions are modeled in terms of a superstructure embedded in the overall model. This approach is applied to a Brandy production plant modeled with high detail level in the operations description. The optimal solution is found and different tradeoffs between process and design variables are assessed. Copyright © 2005 IFAC
