Freight and warehouse exchanges: modern logistic information systems

Kovács G.

Research in Logistics & Production

2012

Vol. 2, No. 1

43-54

The paper begins with a description about the services of electronic freight and ware-house exchanges currently available on the Internet, then, continues to point out their shortcomings. Based on this, it demonstrates the participants, the aims, the structure and the services of a logistically and economically ideal electronic freight and warehouse exchange system. Then it presents the e-commerce toolbar (catalogue, tenders, auctions), which gives the framework of choosing. It empha-sises the application of a self-developed multi-criteria decision supporting algorithm (based on AHP – Analytic Hierarchy Process -) in the assessment of offers received for tender. The paper describes one optimum search problem emerging in electronic freight and warehouse exchanges, then presents, in details, the ant colony algorithm (BA_ACO) for its solution (to support the complex logistics processes). The demonstration of the modules and operational process of this system is done with the help of self-developed VBA-based (Visual Basic Application) algorithms.
