A new multi-objective intermodal hub-location-allocation problem is modeled in this paper which both the origin and destination hub facilities are as an M/M/m queuing system. The being formulated a constrained bi-objective optimization model to minimize total costs well minimizing system time. small-size solved on GAMS software validate accuracy of proposed model. As becomes strictly NP-hard, MOIWO algorithm with efficient chromosome structure fuzzy dominance method solve large-scale...

The concept of sustainability in supply chain management refers to a logical balance between economic development, environmental considerations, and social responsibilities. In this paper, sustainable model has been proposed design network textile industries considering the key factors. Regarding type industry characteristics area under study (Zanjan,northwest Iran), minimizing negative e ects wasteful extraction ground waters pollution resulting from industrial wastewaters maximizing...

This paper proposes an integrated approach for dynamic facility layout problem considering the material handling equipment (MHE). The objectives of this are minimization fixed costs MHE, cost (MHC) and machine rearrangement (MRC). To be more realistic, MHE costs, MRC MHC, which might different importance to decision maker, considered separately in three objective functions. An model is proposed able simultaneously select along with arranging re-arranging facilities. belongs class...

Supply Chain Operations Reference (SCOR) model is developed and maintained by the Council (SCC). The a reference which can be used to map, benchmark improve supply chain operations. SCOR provides companies with basic process modeling tool, an extensive database defines set of metrics. Mobarakeh Steel Company (located in Isfahan, Iran) initiated project studying analyzing its performance based on model. This paper explains steps results project. Interviews managers considering documents four...

For retailing systems, arranging the perishable products has always been a challenge. Although more profit is made when are sold with FIFO policy, now customers taste in competitive market which requires new to be offered them changed game. This paper considers hybrid of FIFO-LIFO strategies for controlling retailer's stock and its impact on profits vendor managed inventory contracts. The problem formulated as multi-period, multi-store integer programming model aims maximize total profit....

Closed loop supply chain design is to provide an optimal platform for efficient and effective management. It essential strategic operation management problem in management, usually includes multiple conflicting objectives. A new mixed integer non-linear programming model a multi-objective closed network the paper industry developed under uncertainty. The objective functions are minimize total cost, maximize volume flexibility number of vehicles hired order fulfill industry'spolicies towards...
