With the trend of globalization, supply chains are increasingly extended and uncertainties associated with material flow along the supply chain have become a major challenge in the planning process. In this study, we examine the effect of supply uncertainty on dynamically managing a two-stage supply chain under both centralized and decentralized controls. Specifically, the downstream faces dema...

Many supply chain problems involve optimization of various conflicting objectives. This paper formulates a green supply chain network throughout a two-stage mixed integer linear problem with uncertain demand and stochastic environmental respects level. The first objective function of the proposed model considers minimization of supply chain costs while the second objective function minimizes CO...

Models that aim to optimize the design of supply chain networks have gained more interest in the supply chain literature. Mixed-integer linear programming and discrete-event simulation are widely used for such an optimization problem. We present a hybrid approach to support decisions for supply chain network design using a combination of analytical and discrete-event simulation models. The prop...

This paper concerns the estimation of an intertemporal model for labour supply and consumption that recognises the presence of nonworkers and which is cast in a structural optimising framework that allows for uncertainty. Through the utilisation of a micro-data source that measures consumption and labour supply we are able to estimate a flexible preference model which incorporates comer solutio...

Supply chains continually face the challenge of efficient decision-making in a complex environment coupled with uncertainty. While plenty of forecasting and analytical tools are available in the market to evaluate and enhance Supply Chains’ performance, the current functionalities are not sufficient to address issues related to efficient decision making under uncertainty. In this paper we discu...

Uncertainty is an inherent factor throughout the whole supply chain (SC) channel within production, distribution, transportation, and market sales. In traditional manufacturing processes, stochastic capacity, random yield, and uncertain transportation delay are regarded as the main causes of supply uncertainty. Market fluctuations, brought on by ever-changing customer preferences and competitiv...

Supply chain management (SCM) has become one of the most popular and fastest growing areas in management. One major issue of SCM is the proper design of supply chains to serve customers effectively (high customer service) and efficiently (at low costs). This is particularly difficult as companies nowadays face a series of challenges like shrinking product life cycles, the proliferation of produ...

The Supply Chain (SC) members are dependent on each other for resources and information, and this dependency has been increasing in recent times due to outsourcing, globalization and rapid innovations in information technologies. This increase in dependency brings some extent of risk and uncertainty too along with benefits. To meet these challenges, SC members must work towards a unified system...

Practically all supply chains operate under conditions of uncertainty. To mitigate this uncertainty and increase performance, organizations within chains exchange information to achieve operational cohesion. However, as some researchers have noted, some supply chains benefit more from increased levels of information sharing than others (e.g. Cachon & Fisher, 2000). To assist in explaining the p...
