Comparative studies of actual and estimated costs in transportation infrastructure development are few. Where such studies exist, they are typically single-case studies or they cover a sample of projects too small to allow systematic, statistical analyses (Bruzelius et al., 1998; Fouracre et al., 1990; Hall, 1980; Nijkamp & Ubbels, 1999; Pickrell, 1990; Skamris & Flyvbjerg, 1997; Szyliowicz & G...

Facility location-network design (FLND) problem, which determines the location of facilities and also communication links between the demand and facility nodes, is arisen from the combination of the facility location and network design problems. This paper deals with fuzzy capacitated facility location-network design model which aims to select the facilities and candidate links in a way that yi...

vehicles have an important role in passenger transportation in iran. this paper runs an economic appraisal on intercity buses, minibuses and public four-seated conveyances of mazandaran province in view point of private and public sectors. the benefit-cost ratio, costs adjusted efficiency, necessary capital for job creation for a labor force and labor force adjusted productivity, which are used...

BACKGROUND/AIMS This study analyzed the scale and trends of the social and economic costs of liver disease in Korea for the past 5 years. METHODS The social aspects of socioeconomic costs were projected for viral hepatitis (B15-B19), liver cirrhosis, malignant neoplasm of the liver (C22) and other liver diseases (K70-K76), as representative diseases by dividing costs into direct and indirect ...

For most people living in developing countries “health insurance” is unknown. It is generally assumed that, with the exception of the upper classes, people cannot afford such type of social protection. Poor people need protection against the financial consequences of illness. For most people living in developing countries illness still represents a permanent threat to their income earning capac...

The aim of this work was to study a distribution and lot-sizing problem that considers costs with transportation to a company warehouse as well as, inventory, production and setup costs. The logistic costs are associated with necessary containers to pack produced items. The company negotiates a long-term contract in which a fixed cost per period is associated with the transportation of the item...

The analysis of the most researches related to the supplier selection shows that very little attention is given to transportation although its cost may be significant important to this selection. In this paper, we present a multiobjective approach of selecting suppliers and allocating the order quantity among them, taking into account transportation. The objectives to minimize in the model are ...

This research focuses on estimating and understanding the costs and causes of transportation related supply chain disruptions. In-depth interviews with logistics managers were undertaken to investigate how companies perceive transportation related supply chain disruptions and what they are doing to respond and address them. Stated choice experiments were designed to estimate the cost of disrupt...

This paper presents experimental evidence suggesting that persistant price dispersion that violates the law of one price may be a disequilibrium phenomena. Increasing market concentration increases the pecuniary incentive to give a best response and satisfy the law of one price, that is, a few large rms have a larger pecuniary incentive to solve the allocation coordination problem than many sma...

Vehicle routing problems (VRPs) are very popular mainly because of their interesting combinatorial properties and applications to various industries. Informally, the problem is to provide a service to a set of customers using a fleet of vehicles so as to minimize the ‘transportation costs’ without loosing ‘customer satisfaction’. Many variations of the problem have been formulated corresponding...
