Terminals are key components of intermodal transport networks, as they are the facilities where freight is transferred between transport modes. The efficiency of such facilities crucially depends on their locations (and sizes), which are typically chosen considering two levels of analysis: local/urban and regional/country. Our focus in this presentation is the regional/country level. At this level, the problems involved in the locational (and sizing) decisions at stake are a particular variety of hub locations problems—a class of problems that has been widely studied through optimization approaches. However, they typically assume that decisions are made in a centralized management context: decision-makers not only choose the locations of intermodal terminals (or hubs), but also fully control their utilization (i.e., which terminal each user will patronize). This signifies that such approaches are not applicable when users–potentially, any companies that move freight–behave according to their own individual interests; that is, they are not applicable in a decentralized management context. In this presentation, we describe an ongoing study where (regional) intermodal terminal location problems are dealt with in this type of context considering terminals of different types and respective capacity and operation ranges. In particular, we present the complex optimization model we have developed to handle such problems, and the (sometimes counterintuitive) results it led to when applied to a case study inspired by the Portuguese reality.

This paper analyzes the degree of development and the status quo in the process of preservation-exploration of geoheritage landscape resources in Xinjiang in order to define the present model of protection and exploitation. The development pattern and the management pattern for geoheritage landscape resources are believed to be optimized respectively under the perspective of protection and benefit sharing. Based on this idea, this paper points out that the optimization pattern for preservation-exploration of geoheritage landscape resource in Xinjiang is a double-winged optimized pattern for it is the perfect mixture of exploration optimization model from preservation perspective and management optimization pattern from interest sharing perspective.
