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

Öz

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.

Tek Özelliği Test Edilen Ürünlerin Test Sürecinde Ekipman Seçimi İçin Kısıt Programlama Temelli Optimizasyon

Öz

Test süreci, özellikle karmaşık ürünler için, işletme kaynaklarının doğru planlanmasını gerektiren önemli bir maliyet bileşenidir. Literatürde hem teknik hem de yönetim içerikli çalışmalarda test süreci ayrıntılı olarak işlenmekte, test karakteristikleri ile çıktı ürün kalitesi arasındaki ilişki ortaya konmakta, fakat optimal test ve tamir ekipmanı seçimi, bir optimizasyon problemi olarak ele alınmamaktadır. Bu çalışmada mükemmel olmayan bir test ve tamir döngüsünün dinamikleri ve ilintili ekipman seçim optimizasyonu problemini çözecek bir kısıt programlama modelinin yapısı açıklanmaktadır. Tamir makineleri için de genellenebilecek bu model, gerçekçi bir maliyet hesabı yaklaşımıyla ideal test ekipmanı seçimi yapılmasına yardım etmektedir.
