In 1993 during the process of the German reunification East Germany raised the blood alcohol concentration limit from 0% to 0.08%. Three roadside surveys were conducted to assess the short-term and long-term effects of raising the blood alcohol concentration limit (directly before the change, at...

We investigate the causes of increasing concentration in the Canadian air carriers industry over the last four decades, and assess possible links with deregulation and investment decisions. We measure the technology of firms in a dynamic framework that includes regulation. The model is tested...

This study examines the relationships among commercial revenue, passenger service level and space allocation in international passenger terminals. Using mathematical programming, this study constructs a model for maximizing concession revenues while maintaining service level, to optimize the...

This paper proposes a joint replenishment program coupled with a channel coordination practice, to investigate their effect on supply chain improvements. We formulated several supply chain models, with a manufacturer supplying a family of products to a retailer, and the products sharing a common...

This paper presents an optimization-based model to deal with integrated logistics operational problems of green-supply chain management (G-SCM). In the proposed methodology, a linear multi-objective programming model is formulated that systematically optimizes the operations of both integrated...

In this paper, we consider the dynamics of a global supply chain network economy in the presence of risk and uncertainty in which distinct speeds of adjustment are included. We assume three tiers of decision-makers: manufacturers, distributors, and retailers, who acquire the product in order to...

The paper investigates the effects of relationship orientation in the logistics service provider-client interaction. A conceptual model is developed and six research hypotheses are empirically analysed using structural equation modelling. The results indicate that relationship orientation has a...

A game theoretical approach is applied to model the strategic interactions between the operators in a deregulated bus market, taking into consideration price competition as well as competition over service frequency. The conditions for market entry and predatory behavior are determined. The...

The scale of the global chemical industry is enormous: in 2003, the total value of global production exceeded US$1.7 trillion. International logistics is especially crucial to the high-value chemicals industry, since raw materials sources, production facilities, and consumer markets are...

We build a nested logit model to study the roles of aircraft size, together with service frequency, seat availability and fare, in airlines' market share and total demand in non-stop duopoly markets. We find that airlines can obtain higher returns in market share from increasing service...
