This paper is concerned with solving a vendor–buyer integrated inventory problem with rework and a specific multi-delivery policy by a two-phase algebraic approach. Conventional method to the problem is to use differential calculus and Hessian matrix equations to prove convexity of system cost...

This paper examines a vendor–buyer integrated system that includes rework and an enhanced product delivery policy that aims at lowering stock holding costs for both the vendor and the buyer. It extends the recent work of Chiu et al. (2011) by incorporating an amending ‘n+1’ shipment policy...

In a recent study [Chiu et al., 2007. Determining the optimal run time for EPQ model with scrap, rework, and stochastic breakdowns. European Journal of Operational Research 180, 664–676], the perfect rework of nonconforming items was assumed in a production system that is subject to stochastic...

Operating in highly competitive global markets, management of the contemporary corporations constantly seeks to cut down various operating costs, such as inventory holding costs in the production units and their affiliated retailers. For the purpose of reducing stock holding cost, this paper...

This paper addresses the joint determination of a rotation cycle time and number of shipments for a multi-item economic production quantity (EPQ) model with random defective rate. The classic EPQ model considers production planning for a single product with a perfect production process and...

This study employs an alternative approach to determine common production cycle time for a multi-item production system with discontinuous deliveries and failure in rework. A straightforward approach using algebraic derivation is proposed here to reexamine a specific common cycle time problem...

The optimal replenishment policy for an economic production quantity (EPQ)-based inventory model with nonconforming items and breakdown is presented. A real-life production system inevitably generates nonconforming items and has equipment breakdowns owing to process deterioration or other...

The correlation between a firm’s size and its productivity level varies considerably across OECD countries, suggesting that some countries are more successful at channelling resources to high productivity firms than others. Accordingly, we examine the extent to which regulations affecting...

High expectations surrounded the two waves of eastward EU enlargement in 2004 and 2007, with the extension of the EU Internal Market being expected to deliver a substantial boost to economic growth in new and old member States alike. Indeed, considerable progress has been made, with existing...
