Abstract

The research aims to study the Theory of Constraints (TOC), its consider modern philosophy in industry organization which aims of throughput through determine optimal production mix in resources allocation for increase contribution margin and increase profitability through importance constraints and explain its constraints in throughput quantity and explain the role of theory of constraints in improvement effective the optimal production mix in economic units .
The research boil down some importance conclusions such as the of theory of constraints consider standard approach to deal with economic units through determine the internal and external constraints and throughput max based on theory of constraints through throughput max of constraints process. The theory of constraints help in improvement effective the optimal production mix in economic units. This research applied in Al Qadisiya Yoghurts Factory for fiscal year at ending Des. 31, 2011. This research boil down some importance recommendations for improvement effective the optimal production mix in economic units through theory of constraints
