Real-life freight-distribution problems are characterized by a high degree of complexity. Although this kind of problem has been addressed broadly by the operation research community, models proposed in the literature are not able to completely describe real distribution problems, and while attempting to simplify and generalize the problem, they neglect aspects that could be of crucial importan...

The purpose of this paper is to provide an overview of how the intelligent transportation system (ITS) supports freight transportation operations. A study of the literature on transportation information and communication technology (ICT) and intelligent (or smart) transportation systems has been conducted. Documents of more than 60 companies producing or using intelligent transportation technol...

iran is one of the countries facing the most severe farmland fragmentation (ff) in rural areas and farmland consolidation (fc) is generally regarded as being a suitable instrument to solve this problem . a case study in the central area of iran was conducted to explore landholder's attitudes towards issues related to ff and fc. randomized stratified sampling frame was used to select 146 landhol...

ITE JOURNAL / DECEMBER 2004 INTRODUCTION AND SCOPE OF PAPER Planning for freight transportation in urban areas is not performed as commonly or as thoroughly as planning for passenger transportation, despite the fact that one of the seven factors for metropolitan planning specified in the federal legislation (the Transportation Equity Act for the 21st Century) mentions freight. Most planners and...

Freight trucks are known to be a major source of air pollutants as well as greenhouse gas emissions in U.S. metropolitan areas, and they have significant effects on air quality and global climate change. Emissions from freight trucks during their deliveries should be considered by the trucking service sector when they make routing decisions. This study proposes a model that incorporates total d...

In this study, an investigation of long-term forecasts relating to the development of the transport sector in Poland is performed, including the ones by 2030 and 2050. Selected transport development forecasts from the perspective of the membership of Poland in the European Union are presented and most of all, from the perspective of national studies. The basement for the review was the prognosi...

In batch production systems, multiple items can be processed in the same batch if they share sufficiently similar production parameters. We consider the batch consolidation problem of minimizing the number of batches of a finite set of items. This article focuses on the case in which only one or two items can be processed in a single batch. The problem is NP-hard and cannot be approximated with...

We consider a problem of minimizing the number of batches of a fixed capacity processing the orders of various sizes on a finite set of items. This batch consolidation problem is motivated by the production system typical in raw material industries in which multiple items can be processed in the same batch if they share sufficiently close production parameters. If the number of items processed ...
