We introduce a heuristic method for finding good feasible solutions for multi-product lot sizing problems with general assembly structures, multiple constrained resources, and non-zero setup costs and setup times. We evaluate the performance of this heuristic by comparing its solutions to...
We consider the reorder point, order quantity inventory model where the demand, D, and the lead time, L, are independently and identically distributed (iid) random variables. This model is analytically intractable because of order crossover. However, we show how to resolve the intractability by...
We develop an open information standard to assist supply chain modeling, analysis, and decision support. The Supply Chain Modeling Language (SCML) is a platform- and methodology-independent Extensible Markup Language (XML)-based markup language for storing supply chain structural and managerial...
We consider the issue of call center scheduling in an environment where arrivals rates are highly variable, aggregate volumes are uncertain, and the call center is subject to a global service level constraint. This paper is motivated by work with a provider of outsourced technical support...
