in order to improve the level of intelligence, availability, being on demand, convenience, information and humanization of rural public transportation systems, they are more willing to use modern information and communicative technologies. in addition to management services, intelligent transportation systems can provide passengers, drivers, travel agencies and other institutions with other ser...

The existence of a series of problems in transportation management of public and personal vehicles causes to consider intelligent transportation systems. Hence, here we investigate to introduce and the performance of intelligent transportation system ITS which is among new technologies in information technology and at last the importance and necessity of lack of delay in data and informat...

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....

The dial-a-ride problem is a classic challenge in transportation and continues to be relevant across a large spectrum of applications, e.g. door-to-door transportation services, patient transportation, etc. Recently a new variant of the dial-a-ride problem, called ride-sharing, has received attention due to emergence of the use of smartphone-based applications that support location-aware transp...

In this paper, we propose a new mathematical model for Capacitated Inventory Routing Problem (CIRP), which considers freshly delivery of perishable products to the customers’ location; otherwise, a reduction in products’ demand may occur. Therefore, we attempt to plan delivering process of products at the right time to avoid extra inventory causing increase in age of products. This ...

in this paper the conditional location problem is discussed. conditional location problems have a wide range of applications in location science. a new meta-heuristic algorithm for solving conditional p-median problems is proposed and results are compared to those of the previous studies. this algorithm produces much better results than the previous formulations.

Title of dissertation: A STUDY OF FOUR NETWORK PROBLEMS IN TRANSPORTATION, TELECOMMUNICATIONS, AND SUPPLY CHAIN MANAGEMENT Si Chen, Doctor of Philosophy, 2007 Dissertation directed by: Professor Bruce Golden and Associate Professor Subramanian Raghavan Robert H. Smith School of Business The increasing material costs and the rapid advances in computing technology have both motivated and promoted...

This work concerns a special class of multicriteria optimization problems, obtained from a given single-facility multicriteria planar location problem by adding several new cost functions. By means of a decomposition approach, based on the concept of Pareto reducibility, we have developed together with S. Alzorba and Chr. Günther an implementable algorithm for generating efficient solutions of ...

Hubs are facilities used to treat and dispatch resources in a transportation network. The main idea of Hub Location Problems (HLP) is to locate a number of hubs in a network and route resources from origins to destinations such that the total cost of attending all demands is minimized. In this study, we investigate a particular HLP, called the Tree of Hubs Location Problem in which hubs are con...

There are important connections between transportation and industrial location. Falling transportation costs increase the feasible scale of production and promote trade, centralization. But as cheap transportation makes many physical inputs effectively ubiquitous, other factors, particularly the availability of specially skilled workers, proportionately more important. Increasing returns and th...
