Multi-Agent Distributed Coordination of Project Schedule Changes

This article shows a practical application for Distributed Coordination framework for Project Schedule Changes (DCPSC) wherein a project can be rescheduled dynamically through negotiations by all of the concerned project participants. This article presents the design and implementation of a multi-agent system called Distributed Subcontractor Agent System (DSAS), which consists of multiple subcontractor agents, multiple Graphic User Interfaces (GUIs), and an Agent Message Router. In the DSAS, subcontractors interact with their software agents to evaluate the impact of changes, simulate decisions, and get the negotiation results that they need to reschedule the project. This also presents the design and results of DSAS charrette tests, which demonstrated that DSAS produces the lower-cost results faster than manual centralized processes. DSAS can be useful for other domains, such as Mechanical, Electrical, and Plumbing (MEP) coordination and workspace management, if the appropriate agents are designed.
