Up to now, research on speed-up techniques for DIJKSTRA’s algorithm focused on single-criteria scenarios. The goal was to find the quickest route within a transportation network. However, the quickest route is often not the best one. A user might be willing to accept slightly longer travel times if the cost of the journey is less. A common approach to cope with such a situation is to find Paret...

A multi-objective multi-node dynamic route planning system for a vehicle is presented in this paper. In this system, a bidirectional heuristic search algorithm is designed to perform path planning between two nodes in a topological map created by OpenStreetMap for urban scenarios. And then an improved multi-objective Ant Colony Optimization (ACO) algorithm considering the timeliness of goal nod...

transport route planning is one of the most important and frequent activities in supply chain management. the design of information systems for route planning in real contexts faces two relevant challenges: the complexity of the planning and the lack of complete and precise information. the purpose of this paper is to nd methods for the development of transport route planning in uncertainty dec...

Highways are one of the main structures cities in field economic, social, and environmental facilities that connect cities, regions, people each other. Determining suitable highway routes includes difficult complex processes due to construction costs. Additionally, priorities, expectations, constraints for parameters must be considered together provide efficient solutions requirements. Multi Cr...

This paper describes a multimodal travel system (MTS) designed to address the needs of a variety of demand-responsive transport. An origin–destination (O–D) trip in transportation network can be accomplished by using multiple modes. In urban network passengers may boarding buses or metros to go from one place to another, and modes as autobus or trains are used by passengers to travel between ci...

Multitask emergency logistics planning is a complex optimization problem in practice. When disaster occurs, relief materials or rescue teams should be dispatched to destinations as soon possible. In nutshell, the can described an of multipoint-to-multipoint transportation delivery given multimodal traffic network. this study, network considered for planning, and mixed-integer programming (MIP) ...

The work presented in this paper aims to model and solve multi-criteria international itinerary planning problems The emerging itinerary planning problems are defined on a multimodal time-dependent transportation network that consists of hierarchically interconnected international, interurban and urban transportation networks. The itinerary planning problems under study fall into two major cate...

tourism as a growing industry needs special attention in developing countries. during last decades, nature based tourism has been growing faster than other tourism fields and it seems to grow even faster. ever growing demand for nature based tourism emphasizes the necessity of a holistic planning for preserving environment against degradation. objective of this study is to present a nature base...

in the last few years, public awareness has been on the increase about short- and long-term effects of forest roads construction on the environment. therefore, forest road managers have to be concerned about the negative impacts and mitigate them as much as possible. this research conducted multi-criteria analysis techniques in a useful way to define the effective criteria and propose a model f...
