On-line vehicles dispatching rules are widely used in many facilities such as warehouses to control vehicles' movements. Single-attribute dispatching rules, which dispatch vehicles based on only one parameter, are used commonly. However, multi-attribute dispatching rules prove to be better in...

Customer order response time and system throughput capacity are key performance measures in warehouses, which depend strongly on the storage strategies deployed. One popular strategy is to split inventory into a bulk storage and a pick stock, or forward-reserve (FR) storage. Managers often use a...

This study investigates the effect of safety-specific transformational leadership (SSTL) on the performance outcomes of safe driving and driving productivity in both long and short-haul truck cargo transport. We conduct our study in the context of a hazardous material (HAZMAT) Indian transport...

An upward line extension is a new improved product within an existing product category for the high end of the market. Many firms pursue line-extension strategies, but such strategies carry risks due to uncertain consumer taste, the internal competition between products, and the external...

The order batching problem (OBP) is the problem of determining the number of orders to be picked together in one picking tour. Although various objectives may arise in practice, minimizing the average throughput time of a random order is a common concern. In this paper, we consider the OBP for a...

Internal transport systems using automated guided vehicles (AGVs) are widely used in many facilities such as warehouses, distribution centers and transshipment terminals. Most AGV systems use online dispatching rules to control vehicle movements. In literature, there are many types of...

This paper presents a review on design and control of automated guided vehicle systems. We address most key related issues including guide-path design, estimating the number ofvehicles, vehicle scheduling, idle-vehicle positioning, battery management, vehicle routing, and conflict resolution. We...

Puzzle-based storage systems (PBSs) can achieve very high utilization of expensive and scarce storage space coupled with fully automated storage and retrieval of unit loads. A PBS system with one empty cell is comparable to the well-known 15-puzzle, in which 15 tiles slide in a 4×4 grid. This...

In the last decades, many retailers have started to combine traditional store deliveries with fulfilment of online sales to consumers, from omnichannel warehouses, which are increasingly automated. One popular way of warehouse automation is with Autonomous Mobile Robots (AMRs), that collaborate...
