20150081263 | PRODUCTION SIMULATION APPARATUS AND PRODUCTION SIMULATION METHOD - According to the present invention, an accurate simulation result is obtained and computation time is shortened, by parallel computation of a production simulation executed by a plurality of processors. A target product line is divided into a plurality of blocks, and event groups which can be computed in parallel while acquiring accurate simulation results are formed based on the order of execution dates and times of the events in the divided block. First, a step effect relationship which shows whether or not an event computation process in a certain step affects an event computation process in another step is acquired, based on a production line configuration such as a step order and resource sharing relationship between the steps. Next, the production line is divided into a plurality of blocks which do not affect each other by putting the steps that affect one another into a block. In a case where the earliest execution date and time of an event in a certain block is later than the earliest execution date and time of an event in another block which the certain block affects, an event group which can be computed in parallel is formed by determining that the event with the earliest execution date and time of the certain block is an event which can be computed in parallel. Lastly, the formed event group is allocated to a plurality of processors so as to be computed in parallel, and thus, computation time is shortened. | 03-19-2015 |
