gasoline is the most important energy product in the passenger transportation sector in iran. gasoline demand survey has a high priority in iran because of its ever-increasing consumption. the most important challenges for this purpose are uncertainties resulting from structural failure of economy, changing of policies and lack of accurate data. this research aims to specify the variables expla...

Several reasons justify the expectation of increasingly price elastic demand for dairy products. Using weekly scanner data, we find support for this hypotheses, but with wide variation in elasticity estimates across model specifications. The results demonstrate the need for more routine specification testing before basing recommendations on potentially fragile inferences. keywords: dairy produc...

An optimization-based control framework that simultaneously determines the optimal inventory and product pricing policies is developed for multi-product, multi-echelon supply chain networks. The optimization problem aims at adjusting the available manufacturing resources, product transportation, inventories and prices for the entire supply chain network to satisfy demand while maximizing networ...

in this paper, the problem of determining the quality level, lead time for order delivery and price of a product produced by a manufacturer is considered. in this problem the demand for the product is influenced by all three decision variables: price, lead time and quality level. to formulate the demand function, a fuzzy rule base that estimates the demand value based on the three decision vari...

This paper presents a model of the introduction of a product line that consists of a high-end model and a low-end model, under conditions of demand uncertainty. The firm is a-priori uncertain about the demand for the product line, which can turn out to be either high or low. The firm learns of the actual demand conditions only after at least one product in the line has been introduced. We start...

this research provides an optimization tool for use by supply chain managers in the design and operation of manufacturing- distribution networks under uncertain demand conditions. the problem under consideration consists of determining the supply chain infrastructure; raw material purchases, shipments, and inventories; and finished product production quantities, inventories, and shipments neede...

selecting a set of features and price for new product is one of the most important and difficult decisions for any firm. for its implementation firms require information by demand of consumers about product features,the cost of providing these features and reaction of existing competitors to new product entry. in this research, with the help of game theory, the various positions of new product ...
