This paper introduces an iterative two-phased approach to decide on the centralisation versus decentralisation of the hospital sterilisation service department. The first step consists in searching for the optimum configuration that minimises the sterilisation activity cost, while the second...

This paper incorporates the effect of process inspection and restoration (Ben-Daya and Rahim, 2003) in an imperfect production process while considering three different scenarios (Ojha et al., 2007): 1) single lot of raw material?multiple lot of finished product?multiple delivery of the product,...

The ordering policy for retailers and the suppliers' system are influenced by lead time and deterioration. In this study, we consider deteriorating items with triangle-shaped demand and uncertain lead time. The triangle-shaped demand has the characteristic of increasing demand during the...

This paper presents a new statistics-based evolutionary algorithm to improve the qualities of power supplies, in which operational costs and the stability of the power supply are optimised to provide a highly smooth but low-cost power supply service to customers. The proposed method is...

This research develops a demand management system, incorporating a machine-rate model, a rough-cut capacity planning (RCCP) model, and a demand management model for the fishing-net production industry. The machine-rate model is used to calculate a machine workload for the RCCP model to estimate...

Manufacturing execution system (MES) provides a common and single system to support most manufacturing processes. However, MES applications do not address all of the manufacturing execution processes required to replenish the supply chain while dynamically responding to unpredicted change and...

In this paper, we consider a two-stage supply contract model for advanced reservation of capacity, with payback option at the beginning of the selling season. Between the two decision stages, external information is collected that serves to update the demand forecast and permits to adjust the...

This article presents an exact cooperative method for the solution of the multidimensional knapsack problem (MKP) which combines dynamic programming and branch and bound. Our method makes cooperate a dynamic programming heuristics based on surrogate relaxation and a branch and bound procedure....
