<p>PROBLEM TO BE SOLVED: To surely check whether plural objects having setting periods satisfy whole objective periods or not by combining the respective setting periods. SOLUTION: a) a step for obtaining non-setting periods by subtracting respective setting periods from objective periods and storing the obtained non-setting periods in a storage means as non-setting period records on all objects, b) a step for sequentially subtracting the respective setting periods from the non- setting periods on one non-setting period record which is stored in the storage means and is not processed, c) a step for setting the non-setting period record to be processed and the step of b) is repeated on the next non-setting period record when a result obtained by subtracting the setting period from the non- setting period is zero, setting the non-setting period record to be processed, storing the plural non-setting periods generated by division in the storage means as the non-setting period records and repeating the step of b) on the next non- setting period record when the non-setting period is divided into plural periods and d) a step for outputting the result of the step c), are contained.</p> |
