The blood supply chain as a part of healthcare systems play a substantial role in health improvement within societies, and blood supply for daily needs and especially in disasters is the challenges requiring more attention. This paper presents a fuzzy-stochastic mixed integer linear programming model to design blood supply chain network for disaster relief. To deal with the uncertainty in model...
Recent events have highlighted the need for planners to consider the risk of disruptions when designing supply chain networks. Supply chain disruptions have a number of causes and may take a number of forms. Once a disruption occurs, there is very little recourse regarding supply chain infrastructure because these strategic decisions cannot be changed quickly. Therefore, it is critical to accou...
This paper addresses the optimal design and planning of cellulosic ethanol supply chains under economic, environmental, and social objectives. The economic objective is measured by the total annualized cost, the environmental objective is measured by the life cycle greenhouse gas emissions, and the social objective is measured by the number of accrued local jobs. A multiobjective mixed-integer ...
Optimal control is a convenient way to develop both supply chain process optimization models and describe the dynamics of fulfillment. A rich diversity knowledge has been developed for integration simulation methods with applications management at conceptual, informational, computational levels. At same time, model-algorithmic alignment frameworks have received less attention. The importance th...
This paper focuses on developing an approach and technology for actionable recommendations on the operation of components of an electric power network. The overall direction of this research is to model the major components of a Hybrid Renewable Energy System (HRES), including power generation, transmission/distribution, power storage, energy markets, and end customer demand (residential and co...
In this work, we address a production and inventory routing problem for liquid oxygen supply chain comprising facilities, distribution network, resources. The key decisions of the involve levels plants, delivery schedule through heterogeneous vehicles, strategies national stock-out prevention. Due to complexity, propose two-level hybrid solution approach that solves using both exact metaheurist...
In this paper, a bi-objective model is presented for dynamic and integrated network design of a new entrant competitive closed-loop supply chain. To consider dynamism and integration in the network design problem, multiple long-term periods are regarded during planning horizon, so that each long-term period includes several short-term periods. Furthermore, a chain to chain competition between t...
This paper discusses a new approach that facilitates the use of simulation in supply chain applications, especially for manufacturing-related activities. A neutral information representation methodology, which is based on the eXtensible Markup Language (XML), referred to as the Manufacturing Information Model for Simulation (MIMS), is being developed at NIST to address the needs of information ...
In this paper, a closed-loop location-inventory problem for spare parts is presented. The proposed supply chain network includes two echelons, namely (1) distribution centers (DCs) and repairing centers (RCs) and (2) operational bases. Multiple spare parts are distributed among operational bases from distribution centers in the forward supply chain and failed spare parts from operational bases ...
Recent researches regarding supply chain design mainly focus on a limited tier in single supply chain, which only take into account vertical cooperation and ignore the across-chain horizontal one. This paper, based on cluster supply chain, provides a novel framework and approach to design cluster supply chain without across-chain horizontal cooperation, then by introducing item allocation propo...
