This paper considers the locational effects of geographically discriminatory trade policy. A preferential move towards a free trade area pulls industry into the integrating countries. Input-output links between imperfectly competitive firms amplify this effect and, when trade barriers fall below some critical level, may lead to agglomeration with some member countries gaining industry at the ex...

This paper introduces a special kind of multi-depot pickup and delivery problem. In contrast to the general pickup and delivery problem (GPDP, see e.g. [19, 31]) all requests have to be picked up at or delivered to one central location which has the function of a hub or consolidation point. In hub transportation networks routes between customers and the hub are often short, i.e. involve only on...

In this paper, a two-stage robust optimisation is presented for an uncapacitated hub location problem in which demand uncertain and the level of conservatism controlled by uncertainty budget. first stage, locations establishing facilities were determined, allocation decisions made second stage. An accelerated Benders decomposition algorithm was used to solve problem. Computational experiments s...

Globalization of world economy has led to a rapid growth of container transportation as well as container ports. In China, Shanghai and Ningbo ports have experienced an explosive growth rate based on their strong economic hinterlands. The purpose of this paper is to adopt regional economic theory and methods to quantitatively analyze the spatial structure of the ports cluster and the competitiv...

in this paper smart operation of micro energy hub is presented. energy hub system consists of certain energy hubs and interconnectors that are coordinated by energy hub system operator. an energy hub contains several converters and storages to serve demanded services in most efficient manner from available energy carriers. in this paper, the flexibility of energy delivery point is enhanced u...

Due to their weak nature, such as low inertia, offshore energy hubs are prone unprecedented fast dynamic phenomena. This can lead undesired instability problems. Recent literature, with main focus on onshore systems, suggests that electrolysers could be an attractive option support wind generators in the mitigation of balancing paper presents Electromagnetic Transient (EMT) model for real-time ...
