Two-Criteria Model of Product Mix Based on the Theory of Constraints

Production structure problem, also known as product mix problem (PMP) has been in the area of interest of many researchers. Among many different ways to solve this problem, theory of constraints (TOC) is one of the more frequently chosen ones. However this solution is not universal and in some cases does not generate an optimal solution. In this paper a multi-criteria integer model has been introduced to enhance the concept. Thanks to a thorough analysis of the problem, model can be used both in the companies that have identified the one and only constraint as well as companies that characterize with multi-constraint environment
