One of the particular advantages of the Last Planner System is to bring downstream players, for example construction firms, into upstream design and planning phases in order to make optimal use of all available knowledge. This procedure is actually hindered in many countries by the existing governmental contracting rules. To overcome this problem and to be able to include downstream knowledge in earlier phases of the project a solution based on software agents is proposed. The objective is to devise the software architecture for a decision support system incorporating the Last Planner System as communication platform. As the software agents shall act for persons not available during a Last Planner session they must be integrated in the collaborative process. The paper discusses a concept for this problem based on a Multi-Agent System (MAS) modelling the communication process, and a Service-Oriented Architecture (SOA) to provide different functionalities needed. The concept provides a corner stone for a computer-based simulation of the knowledge of actors who are not available in phases of the Last Planner process.
