Existing research on the transit network design problem has tended to focus minimizing various costs for both operators and users. However, implement an appropriate effective in urban environments, it is important not overly simplify intrinsically complex nature of real-life designs. In particular, minimization variance service levels typically employed existing methods can be significantly imp...

In a linear programming (LP), market demand is assumed to be constant, but the demand is often random variable which is to be realized as time lapses. We refined the previous work of Higle and Wallace (2003) who studied an LP depending on the timing of market demand realization. The motivation of this research is the need to consider three operational strategies used for dealing with demand unc...

When using an on-demand media streaming system on top of a network with Multicast support, it is sometimes more efficient to use broadcast to distribute popular content, especially when client demand is high. There has been a lot of research in broadcasting on-demand content to multiple, asynchronous receivers. In this paper, we propose a family of novel, practical techniques for broadcasting o...

This paper investigates the single period inventory Newsboy problem in a general uncertain environment. Here it is assumed that the uncertainty appears in the market demand of the product. Uncertain demand is used to describe a subjective estimate (not estimated by random/fuzzy demand), linguistically expressed by ‘‘demand is about n’’. Using identification functions of the uncertain variable w...

We use the voluntary adoption of the NuVal shelf nutrition labels by a grocery retailer to estimate the value of these labels to shoppers in the yogurt category. Using an incomplete quadratic almost ideal demand system to represent consumer demand, we found a statistically significant positive effect of these shelf labels on demand for yogurt with above-average NuVal scores. The coefficients on...

This essay analyzes the market demand by eligible participants for in-kind transfer payments of the type that reduce the free market price participants would otherwise have to pay for the product being subsidized. Examples are the Food Stamp Program, public housing programs, and such proposed programs as rent subsidy and health co-insurance programs. Two common forms for such programs are analy...
