| Abstract: | The long-range planning problem for capacity expansion of a chemical complex can be solved as a series of independent lot sizing problems when the flows in the network are fixed. To take advantage of this property, a variable disaggregation technique has been proposed which led to two different ways of reformulating the conventional mixed integer linear programming (MILP) model. The first reformulation led to a model which can be solved as an NLP and an efficient way to take advantage of this special properties was proposed in order to quickly find a good suboptimal solution. The second is an MILP reformulation for exact solutions which leads to faster computational results. |
