Genetic algorithms were the first evolutionary algorithm designed. These algorithms simulate natural selection to produce good solutions quickly for complex problems. Job shop scheduling with sequence dependent setup times is an NP-hard problem – any algorithm to optimize this problem has...

This paper introduces a new coordinating mechanism for a two-echelon service chain with a single service retailer and multiple suppliers. The retailer sells a bundled product with perishable demand to the end customer. Prior to the selling season, suppliers must make components available to the...

Government environmental regulations, along with increasing awareness and demand from customers for firms to be sustainable, are driving firms to implement new technologies to enhance the sustainability practices of their firms. Given a finite implementation horizon and a target improvement...

A corporation that wants to fully embrace sustainability must address all three pillars of the triple bottom line. Among profit, planet, and people, it is this last category that is hardest to measure directly. When a company has remote locations and cannot directly observe effort, the...

The electric power industry finds itself at a critical juncture—increased regulation of its emissions combined with a shift in U.S. energy policy to emphasize renewable energy. Industry executives must determine the timing and the extent of their investments in clean technology to...

The triple bottom line (economic, environmental, and social performance) is an important approach to long-term sustainability of a manufacturing company. However, a manufacturer will always feel pressure to focus on the economic bottom line and to give at least equal importance to the second and...

This paper discusses the integration of sustainability concepts into a quantitative supply chain management course in management science. Specifically, we discuss an exercise using the analytic hierarchy process (AHP) for making sustainability supplier selection decisions incorporating a triple...

In this paper, we analyze a purchase lot-sizing decision that includes transport cost using actual motor carrier freight rates. Lot-sizing models in the literature either estimate motor carrier freight rates with a continuous function or simplify less-than-truckload freight rates unrealistically...

This paper discusses a sustainability exercise for use in a management science course. Specifically, we discuss an exercise using goal programming and Excel Solver for making supplier selection decisions incorporating a triple bottom line approach (economic, environmental and social performance...

This paper discusses a benchmarking study that we conducted over the summer of 2008 as part of the ongoing re-design of our Supply Chain & Operations Management (SC&OM) curriculum. The motivation for this study was our desire to emphasize sustainability (or the triple bottom line of economics,...
