This paper summarizes the findings of a two-year study of digital image distribution and publication, focusing on the Museum Educational Site Licensing Project (MESL). This study (Besser & Yamashita 1998) evaluated the costs, infrastructure, and efforts involved in implementing the MESL project, as well as user reaction to functionality. The study also examined costs of running analog slide lib...

We model the bidding for a government contract in which there is imperfect competition; each bidder is better informed about his own costs than either his rival bidders or the government; and the distribution of the domestic firms’ costs differs from the distribution of foreign firms’ costs because of comparative-advantage effects. We find that the gcyemment minimizes its expected procurement c...

Recently, problems associated with variations of the static demand economic-dispatch problem for an electrical power grid [10] have been considered by several authors, e.g., [5], [7]. However, demand elasticity for electricity may grow with the onset of enormous amounts of electric vehicle charging, see e.g., [1], [4] and the references therein. We consider a noncooperative game played by the g...

in today's globalization, an effective integration of production and distribution plans into a unified framework is crucial for attaining competitive advantage. this paper addresses an integrated multi-product and multi-time period production/distribution planning problem for a two-echelon supply chain subject to the real-world variables and constraints. it is assumed that all transportations a...

This paper formulates a mathematical model for the Green Vehicle Routing Problem (GVRP), incorporating bi-fuel (natural gas and gasoline) pickup trucks in a mixed vehicle fleet. The objective is to minimize overall costs relating to service (earliness and tardiness), transportation (fixed, variable and fuel), and carbon emissions. To reflect a real-world situation, the study considers: (1) a co...

In the petroleum supply chain, oil refined products are often delivered to distribution centers by pipelines since they provide the most reliable and economical mode of transportation over large distances. This paper addresses the optimal scheduling of a complex pipeline network with multiple branching lines. The main challenge is to find the optimal sequence and time of product injections/deli...

In this paper we consider the problem of planning the production and distribution in a supply chain. The situation consists in a set of distribution centers seeking to serve to a set of retailers; these distribution centers are supplied by a set of plants trying to minimize the operation and transportation costs. The problem is formulated as a bilevel mathematical problem where the upper level ...
