Dialog program for the two-criterial dynamic lot size model

The dynamic lot size model with two objectives is studied. The criterion of minimizing the sum of set-up costs and holding costs is complemented by the minimization of the stock. Solutions which are efficient with respect to these two objectives can be derived from parametric one-critical models with combined objective functions. A complete set of efficient solutions which are distinct in their objectives can be found by a BASIC dialog program for personal computers.
