We develop a modeling approach to explain demand variation for an online platform of usergenerated content, and use it to measure the impact of marketing activities on decisions to visit the platform, and on decisions to create and buy content. The model explains individual-level decisions as a function of consumer characteristics, marketing activities, and behavior of other online users, allow...

local bus network is the most popular transit mode and the only available transit mode in the majority of cities of the world. increasing the utility of this mode which increases its share from urban trips is an important goal for city planners. timetable setting as the second component of bus network design problem (network route design timetable setting vehicle assignment crew assignment) hav...

This paper describes an experimentation methodology to measure how demand varies with price and the results of its application at a toy retailer. The same product is assigned different price-points in different store panels and the resulting sales are used to estimate a demand curve. We use a variant of the k-median problem to form store panels that control for differences between stores and pr...

This paper evaluates the pricing and ordering policies of a retailer, facing a price-dependent stochastic demand, within a newsvendor framework, under different degrees of risk tolerance and under a variety of optimizing objectives. These are (i) maximizing expected profit, for a retailer who may be risk-seeker, riskaverse or risk neutral; (ii) deriving a maximin strategy of maximizing a minimu...

In this work we developed EPQ models for deteriorating items by considering stochastic machine unavailability and price-dependent demand. Moreover, we approach the distribution of the machine unavailability using kernel density estimation. Therefore, the assumption of any distribution models, such as uniformly or exponentially distribution can be neglected and the shape of the distribution will...

The importance of drug as a valuable export product in the global economy becomes more clear every day. Understanding the problems of exports and factors affecting it, can be an important step to keep Iran’s position in the world markets and further export development of this product.In this study, Iranian pharmaceutical exports’ supply and demand functions were calculated using co-integration ...

producers and consumers’ price behavior were analyzed in chicken meat market in fars province. monthly average producers and consumers prices from june 1997 to july 2008 were taken into account. changes in the producer and consumer prices indicated that the prices follow an increasing trend with much fluctuations. marketing margin has an increasing trend of violent fluctuations. the result of g...

Consider a distribution system consisting of a set of retailers facing a single-period price-dependent demand of a single product. By taking advantage of the risk-pooling effect and the quantity/volume discount provided by suppliers or thirdparty carriers, the retailers may place joint orders and keep inventory at central warehouses before demand realization, and allocate inventory among themse...
