碩士 === 國立交通大學 === 管理學院碩士在職專班工業工程與管理組 === 93 === In this study, we present a capacity planning model of a wafer probing system with a manufacturer, subcontractors and hybrid production systems of make-to-order (MTO) and make-to-stock (MTS). The manufacturer’s objectives are to meet due-dates of MTO products and stock levels of MTS products. A two-stage approach was developed. In first-stage, an LP model was formulated to allocate machines for MTO products in the manufacturer’s factory. Then, using the outputs of first-stage, an LP model was constructed to allocate MTS products to manufacturer’s factory and each subcontractors and to determine subcontractors’ machines. Finally, we present a near real case to illustrate the two-stage approach and a simulation model was built to evaluate the performances.
