An Integrated Concept for Scheduling Transportation Networks
Abstract
The focus of this research is to investigate and develop methodologies for the integration of optimization, human interactions, simulation, and knowledge base to address the problems of scheduling transportation networks. These four techniques have been traditionally applied in isolation when addressing scheduling problems, resulting in serious modeling limitations. However, the complementary strengths of these techniques suggest a synthesis that would provide dramatic improvement in the ability to solve these problems. We have developed a prototype model that demonstrates the novel power and benefit of this integration. The concept and methodologies have been tested and proven successful. Transportation networks are the fundamental structures associated with the movement and storage of material. The basic elements of the transportation networks include material movement requirements, transportation vehicles, points (facilities for supplying and receiving movement requirements), links (relationships between points), and crews. Through the generalization of the transportation network structure, a large variety of logistics problems can be modeled in the same fashion, bearing similar mathematical properties, and can studied and solved in a disciplined (as opposed to ad hoc) manner.
