This paper describes e-Marketplace that is an area of SCM simulator where players trade autonomously. The requirements for e-Market place are as follows: (1) each player can join the place independently, (2) each player trades concurrently, and (3) the status of each transaction can be monitored and recorded for analysis. To satisfy the requirements, this paper presents (a) agent-type interface, (b) negotiation-type trading protocol, and (c) data load sharing.
