Resumen:
A general multiperiod LGDP (Linear General Disjunctive Programming) model in a multiproduct batch plant has been developed. Both overall production planning and design decisions of the plant are encompassed considering uncertainty in demands represented by a set of scenarios. Specifically, the proposed model considers simultaneously the plant structure (duplication of units in parallel and the new option "in series"), the decision variables of the batch plant (unit sizes, number of batches, total time for producing each product), and the production planning decisions (e.g. plan of production, policy of inventory, purchases of raw materials and sales of products) in each time period within each scenario. Also, this model allows the incorporation of new equipment items in different periods. The overall objective is to maximize the expected net present value of the benefit. The benefits of the simultaneous optimization of production planning and design decisions under uncertain product demands in a multiscenario approach are demonstrated through a particular extraction process that produces oleoresins. © 2009 Elsevier B.V.
