Economic sustainability under supply chain and eco-industrial park concurrent design
No full textFrom a systemic point of view, the environmental efforts of single companies to achieve sustainable economic and environmental development are not enough because of the economic difficulty of reaching both zero-waste production state and high level of resource efficiency. This work focuses on payback period as a commitment keeping mechanism to ensure network stability at least until the recovery of the investment made for value creation from waste. A scenario analysis is proposed to investigate how the characteristics of each stakeholder within a network can affect the economic sustainability of the others
An effective approach for total completion time minimization subject to makespan constraint in permutation flowshops
No full textThis article addresses the permutation flowshop scheduling problem with the objective of minimizing the total completion time subject to a makespan constraint. The makespan is related to system utilization while the total completion time is related to the waiting time, and hence to the work in process (WIP); in real contexts, focusing on both total completion time and makespan allows a good trade-off between WIP and utilization to be found. Two local search algorithms are developed in the paper and, by using an extensive computational experience on literature benchmark instances, they are proved to be able to find good solutions both for regular and no-wait flowshops
