Constraint Programming Based Optimization of Equipment Selection for Testing Process of Products with a Single Attribute Subject to Test

Testing process is an important cost component, especially for complex products, where companies must carefully plan their resources. Both technical and managerial aspects of the test process, the relationship between test characteristics, and the yield are investigated in detail, but the test and repair equipment selection has not yet been considered as an optimization problem. This paper briefly describes such a process based on an imperfect test – repair loop – and describes a constraint programming approach as a solution method. The model stands for an economic choice of test selection equipment with a realistic cost estimation approach which can also be generalized for repair equipments.
