Performance Evaluation of Real-time Scheduling Approaches in Vehicle-based Internal Transport Systems

Le-Anh, Le-Anh, T.; de Koster, de Koster, M.B.M.; Yu, Yu, Y. - Erasmus Research Institute of Management (ERIM), … - 2006

This paper studies the performance of static and real-time scheduling approaches in vehicle-based internal transport (VBIT) systems, which can be found in manufacturing and warehouse facilities. We propose three heuristic approaches for static VBIT problems (insertion, combined and column...

Leader-follower Game in VMI System with Limited Production Capacity Considering Wholesale and Retail Prices

Yu, Yu, Y.; Liang, Liang, L.; Huang, Huang, G.Q. - Erasmus Research Institute of Management (ERIM), … - 2006

VMI (Vendor Managed Inventory) is a widely used cooperative inventory policy in supply chains in which each enterprise has its autonomy in pricing. This paper discusses a leader-follower Stackelberg game in a VMI supply chain where the manufacturer, as a leader, produces a single product with a...

On the Suboptimality of Full Turnover-Based Storage

Yu, Yu, Y.; de Koster, de Koster, M.B.M. - Erasmus Research Institute of Management (ERIM), … - 2009

In the past thirty years the full turnover-based storage policy as described by Hausman et al. (1976, Management Science 22(6)) has been widely claimed to outperform the commonly used ABC class-based storage policy, in terms of the resulting average storage and retrieval machine travel time. In...
