Unit demands inventory system with acceptance sampling
Ankara : The Department of Industrial Engineering and the Institute of Engineering and Sciences of Bilkent Univ. , 1989.Thesis (Master's) -- Bilkent University, 1989.Includes bibliographical references leaves 38.In this study, an extension to the unit demands inventory
model with exponentially distributed interdemand times is
considered. In this extension orders may arrive in two shipments
due to an acceptance sampling scheme. The defective items that are
detected by the plan will arrive through a second shipment. A
reorder-point, order-quantity (s,Q) type control plan is adopted.
The corresponding cost-rate function is constructed and
numerically optimized for the best operating policy.Akbaş, ZekiM.S
