Weekly scheduling in the service industry: an application to mail processing and distribution centers.
May 1, 2005... 1. Introduction A distinguishing characteristic of organizations in the service industry is that customer demand varies sharply from one period to the next. Hour-to-hour and day-to-day fluctuations make staff scheduling much more difficult...

Management of inventory replenishment and available offerings for goods sold with optional value-added packages.

May 1, 2005... 1. Introduction and motivation Consider a manufacturer who sells a product through his wholly-owned distribution channel as well as other competing retail channels. The manufacturer in this supply system simultaneously acts as a supplier...

Tree network 1-median location with interval data: a parameter space-based approach.
May 1, 2005... 1. Introduction We consider the 1-median location problem on a tree network when the vertex weights are ranges rather than point values. To meaningfully pose the problem, consider first the traditional 1-median problem: [MATHEMATICAL...
