| Outline of Final Research Achievements |
We are studying backward simulation as a tool to evaluate safety of a system. If the backward simulator results in a feasible input range for an abnormal starting output data, it means that the system may not be safe. However, backward simulation models are hard to build in many cases. In this research, we tried a numerical backward calculation model and a case branching simulation method. Simulation results show the effectiveness of our backward simulation for the cases of dynamic pricing of the electricity charges, inference of heater activity from measured room temperature change, and deconvolution of impulse responses. Also, we acquired a knowledge about the relation among branch resolution in backward simulation, processing time and resultant precision.
