A method is introduced to incorporate sustainability considerations in the early design stages, while simultaneously accounting for supply chain factors, such as cost and lead time. Overall, this work is our first step in understanding the trade-offs between sustainability metrics and more traditional supply chain performance metrics (i.e., cost and lead(More)
With increasing competition in the market, expediting the problem solving process has become crucial in the industry. As such, a number of problem solving techniques have been devised to efficiently tackle problems of varying natures. Two such techniques, Theory of Inventive Problem Solving (TRIZ) and Axiomatic Design (AD), have been widely applied in a(More)
We are surrounded by numerous multi-generation product (MGP) lines, ranging from Gillette's razor products to BMW's 3-series sedans. Due to a rapidly changing and technology-intense market environment, the use of an MGP strategy has become a popular management tool for companies; numerous academic and industrial testaments exist pointing to its success.(More)
