The impact of respondent burden and task complexity on quality of stated choice (SC) data remains an issue in transportation research. Furthermore, little is known on the applicability of the technique to less literate individuals in developing countries. This study describes the results of a SC...

Most supply chain models focus on two-stage chains in which vendors supply material to one customer. In this paper, we formulate a three-stage supply chain model where a firm can supply many customers. We deal with three inventory coordination mechanisms between chain members and solve a cost...

In this paper we argue that European airports, on average, are inefficient. Airline inefficiency (low load factors) appears to contribute significantly to airport inefficiency in terms of air passenger movements. We find that the average airport in Europe operates under constant returns to scale...

This paper shows technically that economies of transport network expansion should be viewed through the concept of economies of scope rather than through the concept of economies of scale. The basic technological dimensions that are specific to transport production are identified. The framework...

This paper studies a mixed truck delivery system that allows both hub-and-spoke and direct shipment delivery modes. A heuristic algorithm is developed to determine the mode of delivery for each demand and to perform vehicle routing in both modes of deliveries. Computational experiments are...

Carrier service attributes are important for developing shipper-carrier partnering relationships. This study used structural equation modeling to investigate the impact of carriers' service factors--timing-related, pricing, warehousing and sales services--on shippers' satisfaction from...

The severity of road congestion not only depends on the relation between traffic volumes and network capacity, but also on the distribution of car traffic among different time periods during the day. A new error components logit model for the joint choice of time of day and mode is presented,...

This study investigates the facility location problem of transnational personal computer (PC) manufacturing for the domestic market of China. An integrated supply chain-based spatial interaction model is formulated to determine facility locations of the transnational PC manufacturing centers and...
