This research investigates the interaction of production scheduling and routing/transportation on a logistic network. Basic scheduling rules and existing routing/transportation alternatives were studied using a simulation model, with cost and customer service levels as measures of performance. The simulation model, including network configuration, orders,(More)
In this paper, we examine the dynamics of a supply chain that has the option of using two suppliers ± one reliable, and the other unreliable. We characterize the unreliable supplier with long lead-time mean and variance. Although the use of the unreliable supplier might potentially warrant higher inventory and transportation costs, it is attractive because(More)
