Article history: Received 30 June 2011 Received in revised form September, 01, 2011 Accepted 06 September 2011 Available online 17 September 2011 Demand uncertainty obliges all participants through a supply chain to make decisions under uncertainty. These decisions extend across price, investment, production, and inventory quantities. We take account of competition between two supply chains und...

the health industry’s supply chain is full of uncertainty and unpredictability. thus, building an intelligent system to effectively capture the requirements of customers and help manage the supply chain is very important. despite artificial intelligence widespread acceptance as a decision-aid tool, ai has seen limited application in supply chain management. to fully exploit the potential benefi...

Construction material supply chains have evolved over time to base production and materials management decision-making on demand information from the immediate downstream node in the supply chain. This myopic view leads to demand signal amplification as individual upstream nodes attempt to forecast and fulfill orders. Further compounding this demand distortion is the fact that a great amount of...

In literature, most papers examine several stochastic demand processes where order lead times are constant. In reality, manufacturing firms use inventory management software, especially MRP, which ignored lead time uncertainty. It is true that in certain special cases, lead time uncertainty has essentially no effect and can be ignored. Nevertheless more often, lead time fluctuations strongly de...

This paper examines an integrated decision-making process regarding pricing for uncertain demand and sourcing from uncertain supply, which are often studied separately in the literature. Our analysis of the integrated system suggests that the base stock list price policy fails to achieve optimality even under deterministic demand. Instead, the optimal policy is characterized by two critical val...

The European seed business of Syngenta relies on its supply chain to supply seed products to the different European markets, which led to more than 1.2 billion USD revenues in 2013. The seed supply chain is, however, exposed to a high level of uncertainty – from the demand side as well as from the supply side. Determining optimal production volumes in a highly volatile environment and more than...

Reliable location routing problem considers a location problem and a vehicle routing problem in order to select the optimal location of facilities and at the same time the optimal routes for vehicles considering the unexpected failure for facilities in which, all facilities may fail with a probability. In this paper, a bi-objective mathematical model has been developed to minimize the total cos...

We analyse the effects of wage uncertainty on the labour supply of selfemployed workers, using PSID data on self-employed American males. The standard deviation of past wages, as a measure of wage uncertainty, is the key determinant of male self-employed labour supply, with a significant positive effect. In contrast there is no effect from the (instrumented) wage or other explanatory variables....
