Stock Policy

A consignment stock is a type of supply-chain coordination for the management of supply-chains in which there is a joint vendor and buyer policy that is mainly focused on having the vendor manage the buyer's inventory. This thesis aims to investigate the consignment stock strategy in a single-vendor single-buyer supply-chain context considering imperfect items that may be produced from an imperfect production process. It develops a flexible mathematical model that allows for managerial decisions with regards to imperfect items and seeks to minimize costs (maximize profits) of the supply-chain. Such managerial decisions include scrapping items at a cost, selling them for a marginal profit to a secondary market, applying re-work, and/or applying minor setups to restore the production process. Results show that the introduction of imperfect items increases the batch size and reduces the number of shipments. Minor setups were shown to reduce cost, increase the number of shipments and reduce its size.

Imperfect Production Process

This study considers the supplier's warranty return and the buyer's rebate policy as business-return policy in the supplier–buyer supply chain. The policy as well as the displayed stock level influences the behavior of the buyer. Distinct from the traditional single-stage inventory model, we investigate a two-stage replenishment policy model for deteriorating item considering the effect of imperfect production process, product design, stock level and business-return. A mathematical model utilizing the time weighted inventory (TWI) approach and two-variables fixed point optimization technique is developed to derive the optimal inspection starting time, the number of deliveries, the optimal delivery-time interval and the optimal business-return period. A numerical example is presented to illustrate the model developed. The result shows that the fixed demand rate, the unit holding cost and the unit inspection cost are the critical factors affecting the scheduling and performance of the two-stage supply chain.
