Centralizing and using proper transportation facilities cut down costs and traffic. Hub facilities concentrate on flows to cause economic advantage of scale and multimodal transportation helps use the advantage of another transporter. A distinctive feature of this paper is proposing a new mathematical formulation for a three-stage p-hub location routing problem with simultaneous pick-ups and de...

ABSTRACT At the same time and location, simultaneous time series of wave slope images and the flowfield beneath water waves were obtained using an integrated set-up including particle-tracking and wave slope instruments. By an especially developed tracking algorithm, hundreds of seeding particles can be traced automatically, measuring the flow field. At the the same location the wave-field was ...

Accurate electroencephalographic (EEG) source localization requires an electrical head model incorporating accurate geometries and conductivity values for the major head tissues. While consistent conductivity values have been reported for scalp, brain, and cerebrospinal fluid, measured brain-to-skull conductivity ratio (BSCR) estimates have varied between 8 and 80, likely reflecting both inter-...

Competitive location problems can be characterized by the fact that the decisions made by others will affect our own payoffs. In this paper, we address a discrete competitive location game in which two decision-makers have to decide simultaneously where to locate their services without knowing the decisions of one another. This problem arises in a franchising environment in which the decision-m...

In this work, the capacitated location-routing problem with simultaneous pickup and delivery (CLRP-SPD) is considered. This problem is a more realistic case of the capacitated location-routing problem (CLRP) and belongs to the reverse logistics of the supply chain. The problem has many real-life applications of which some have been addressed in the literature such as management of liquid petrol...

A company frequently decides on location and design for new facilities in a sequential way. However, for a fixed number of new facilities (in this study we restrict ourselves to the case of two new facilities), the company might improve its profit by taking its decisions for all the facilities simultaneously. In this paper a profit maximization problem is considered, where the market share capt...

in order to determine yield stability and evaluation of genotype × environment interaction, 20 spring bread wheat promising lines and varieties were studied in a randomized complete block design with three replications in four warm and dry stations (ahwaz, dezful, darab, & khorramabad) during 2002-2004. chamran cultivar was a check in two years trial. the results revealed that the grain yield o...

The integrated modeling of land use and transportation involves analyzing the entire choice continuum defining people’s lifestyles across temporal scales. This includes long term choices such as residential and work location choices, medium term choices such as vehicle and bicycle ownership, and short term choices such as mode choice and trip departure time choice. In recent times, there has be...

In the case of hazardous materials management, selected routes for carrying hazardous materials (i.e., hazmat) have significant effects on locating hazmat distribution centers. Since, risk and cost are usually considered as two main attributes to determine the best routes, optimized locations are sequentially outlined depending on selected routes. In the present paper, t...
