Introduction to Optimization

Data Flow

The procedures ASSIGN, LP, NETFLOW, NLP, and TRANS take a model that has been saved in one or more SAS data sets, solve it, and save the solution in other SAS data sets. Each procedure defines a SAS macro variable that contains a character string indicating whether or not the procedure terminated successfully and the status of the optimizer (for example, whether the optimum was found). This information is useful when the procedure is one of the steps in a larger program.
