In this paper, we investigate the performance measures of newsvendor model in an environment of customer balking, which occurs when customers are reluctant to buy a product if its available inventory falls below a threshold level. We derive the explicit expression of several performance measures...

We present a location routing model that considers the requirements of real-world small package shippers. It integrates the choice between self-operating and subcontracting a depot. Furthermore, we consider the relocation costs which occur when established networks are restructured. We present a...

This paper studies the simultaneous dock assignment and sequencing of inbound trucks for a multi-door cross docking operation with the objective to minimize total weighted tardiness, under a fixed outbound truck departure schedule. The problem is newly formulated and solved by six different...

The vehicle routing problem with stochastic demand (VRPSD) is a well known NP-hard problem. The uncharacteristic behaviour associated with the problem enhances the computational efforts required to obtain a feasible and near-optimal solution. This paper proposes an algorithm portfolio...

Very large numbers of inventory items complicate the inventory control process. Companies categorize their inventory items into a few groups and take similar inventory control policies for the items in each group to overcome this problem. In this regard many grouping methods have been proposed....

The cutting of logs when the sawing pattern must be defined to produce boards that satisfy a pre-established demand presents a particularly interesting problem. This problem can be reduced to one of optimal bi-dimensional packing of rectangles in a circular container, which we call the problem...
