This paper presents a dual-objective facility programming model for a green supply chain network. The main objectives of the presented model are minimizing overall expenditure and negative environmental impacts of the supply chain. This study contributes to the existing literature by incorporating uncertainty in customer demand, suppliers, production, and casting capacity. An industrial case st...

An important issue for suppliers, producers, and retailers who want to compete in a competitive environment is continuous performance improvement in a dynamic supply chain. Literature review on supply chain puts more emphasis on quantitative factors than other factors. In this research, we focus on quantitative factors which affect competitive advantages creation and investigation. Our goal is ...

this paper explains a model for analyzing and measuring the propagation of order amplifications (i.e. bullwhip effect) for a single-product supply network topology considering exogenous uncertainty and linear and time-invariant inventory management policies for network entities. the stream of orders placed by each entity of the network is characterized assuming customer demand is ergodic. in fa...

In industries like health care, consumer goods and agriculture, shortages are widely observed and the consequences can be costly. One of the main drivers of such shortages is the uncertain nature of supply and demand. To reduce uncertainties, sufficient information about supply and demand can be obtained by gathering relevant data (e.g., auditing suppliers and conducting market research). In th...

Supply chains are subject to various types of uncertainty. According to Geary et al. (2002), these types of uncertainty can be classified in four categories: demand, process, supply, and control uncertainty. In this presentation, we propose and discuss an integrated hierarchical planning approach for supply chains that generates plans which are robust to two particular types of uncertainty, nam...

This paper empirically examines the impact of environmental uncertainty, IT enablers and interorganizational relationships on supply chain flexibility and supply chain integration. Based on the data collected from 196 organizations, multiple regression analyses are used to test the factors impacting supply chain flexibility and supply chain integration respectively. It was found that commitment...

Rapid changes in business and the advent of Internet, have made supply chain management (SCM) important in determining the sustainable growth of companies. However, in a complex hierarchical network that links upstream to downstream firms, several uncertain factors affect the performance of a supply chain. Accordingly, mitigating the deleterious impact of uncertainty is important in planning a ...

This paper explores the differences between demand and supply uncertainty in multi-echelon supply chains. Our central premise is that the insights gained from the study of one type of uncertainty often do not apply to the other. In fact, the two types of uncertainty are in a sense mirror images of each other, in that the optimal strategy for coping with supply uncertainty may be exactly opposit...
