Modern transportation problems are highly dynamic and time critical. A planning system for transportation problems must therefore include efficient and flexible planning and replanning strategies. In this paper we introduce a general agent-based framework for highly dynamic order-based transportation planning problems where a tactical planner and several operational planners (one for each trans...

In the last decade the efficiency of the Artificial Intelligence Planning Systems has been increased significantly. New systems appeared that are able to cope with planning problems being orders of magnitude more complex than the ones solvable in early 90's. This vast improvement increase was made possible mainly by three new approaches in plan generation: planning graphs, satisfiability planni...

Multi-modal transportation is a logistics problem in which a set of goods have to be transported to different places, with the combination of at least two modes of transport, without a change of container for the goods. The goal of this paper is to describe TIMIPLAN, a system that solves multi-modal transportation problems in the context of a project for a big company. In this paper, we combine...

In this paper, we suggest a framework that allows for the simulation-based performance assessment of algorithms for cooperative transportation planning. Therefore, we consider a coupling architecture that connects simulation models of the logistic system and the transportation planning algorithms. The center point of this architecture is a blackboard-type data layer between transportation plann...

A few years ago when the Tri-State Expressway was being planned in the Calumet area, several subdividers were at the same time busy planning several construction jobs in the same area. Unable to ascertain the route of the expressway, they proceeded with their new home construction projects and within a year after the houses were finished 70 of them had to be condemned. It cost more than a milli...

A well-functioning freight transportation system is an essential element in any successful economy. However, at the beginning of the new millennium, the prediction is that the demand for goods movement will outstrip the rate of improvements to the physical infrastructure. Marked growth in time-sensitive freight markets will tax demands on a system that already is operating near capacity in some...

the railway transportation planning under the fuzzy environment is investigated in this paper. as a main result, a new modeling method, called minimum risk chance-constrained model, is presented based on the credibility measure. for the convenience ofs olving the mathematical model, the crisp equivalents ofc hance functions are analyzed under the condition that the involved fuzzy parameter...

ITE JOURNAL / DECEMBER 2005 ONE OF THE MOST FRUSTRATING aspects of being a transportation professional, especially one with an engineering background, is the seeming reluctance of elected officials to readily accept the recommendations of highly qualified technical staffs. This feature is intended to help transportation technical staffs better understand the context within which elected officia...
