This paper addresses the problem of no-wait two-stage flexible flow shop scheduling problem (NWTSFFSSP) considering unrelated parallel machines, sequence-dependent setup times, probable reworks and different ready times to actualize the problem. The performance measure used in this study is minimizing maximum completion time (makespan). Because of the complexity of addressed problem, we propose a...
In this paper, we address a two-stage assembly flow shop scheduling problem with sequence dependent setup times, which minimizes makespan (Cmax) and maximum tardiness (Tmax) as objectives. In this problem, there are n products to be produced; each product has m unique parts to be processed concurrently on m parallel machines at first stage, with each part on a specified machine. At the second stage...
The automation of negotiation among buyers and suppliers has provided cutting-edge knowledge on scientific approaches to the management of supply networks. Concentrating on information flow and cooperation among echelons, studies have designed coordination mechanisms for a two-echelon supply chain: buyers and suppliers. However, quantitative investigations are hardly found that take into account the...
E-supply network coordination (e-SNC) is a new structure obtained by information technology, automation of different echelons' behavior, and the market globalization. The information flow and cooperation among echelons are two key drivers in SN. Here, supply network is considered as a collection of agent-mediated decision and coordination mechanisms in a Web-based environment. The proposed coordination...
The era of fierce competition and globalization, have created an urgency to focus on a change from managing individual functions to integrating activities into key supply chain processes. Supply chain management is now seen as a governing element in strategy and as an effective way of creating value for customers. This paper proposes a system dynamic approach for modeling and analysis of supply networks...
Using FES for reanimation of paralyzed arm has been seriously considered by researchers in recent years. Due to complexities of reaching movement, utilization of a precise model, virtual reality capabilities and advanced control techniques is inevitable. This paper deals with a precise model of paralyzed arm for FES researches. Model elements exactly conform to the elements of the musculoskeletal...
