Framework of e-marketplace for concurrent SCM simulator

This paper describes e-marketplace that is a virtual trading area of SCM (supply chain management) simulator called LOSIMOPU. Being implemented by object oriented technology; LOSIMOPU allows players objects such as end customers and parts suppliers to trade in e-marketplace. The requirements for e-marketplace are as follows: (1) each player object can join in and exit from the area independently, (2) each player object trades concurrently, and (3) the status of each transaction can be monitored and recorded to databases for the analysis. To satisfy the requirements, this paper proposes (a) agent-type interface, (b) trading protocol, and (c) scalability. The prototype system based on these requirements is also introduced.
