This paper proposes a branch-and-bound algorithm for cyclic scheduling of a robotic flowshop with multiple part types in which the processing times of parts can vary within their given time windows. The problem consists of two types of sequencing issues: part input sequencing and robot move...

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...
