Abstract
In order to support the risk management of a construction project, we have developed the system which uses progress simulation technology and supports evaluation of the problem of a project and the decision of countermeasures to a problem. This system is characterized by having the progress evaluation simulation logic which evaluates detailed progress of each work of a project serially per week. Moreover, it also has the function to take into consideration situations, such as change of working efficiency, and increase of the personnel of the number of workers, in simulation logic. This system was evaluated using the data of an actual project, and the validity of the project evaluation result using the various functions of a system was checked.
