Abstract(in English) | Hypothetical reasoning can handle incomplete knowledge as hypothesis.And then,it is applicable for various kinds of practical problems.We apply it for a powersystem database to infer how the electricity is supplied for each electric line making unknown state of switches as hypotheses. The main part of this papers presents the implementation of the ATMS(Assumption Based Truth Maintenance System)on the object- oriented powersystem database.Although the ATMS is an efficient and successful hypothetical reasoning tool,it has crucial problem of exponential growth the computation time as increase the hypothesis size.To escape this problem,we divide the powersystem into some subsystems,and then a local ATMS runs on such a subsystem.thus the size of the subsystem is relatively small,the local ATMS finishes the computation in reasonable time.Finally, they communicate with each other to get global inference result. |
