FACILITY OPERATION CONTROL METHOD FOR PRODUCTION LINE

摘要

PROBLEM TO BE SOLVED: To prolong a life of the facilities of a production line and reduce noise of the facilities by supplying instructions for changing the operation speeds of respective execution time variation steps of the respective facilties to the respective facilities at a time so that an operation speed varied at a specific variation rate is reached. SOLUTION: When the tact time of the production line is varied, the respective shortest operation times of the execution time variation steps of the facilities 1-7 of the production line are acquired and the operation speeds are varied with other instructions. Then the variation rate for varying the operation speeds of the respective execution time variation steps of the respective facilities 1-7 under specific conditions so that all the steps to be executed ends within the varied tact time at time as close to the end of the tact time as possible is found so that the operation time after the speed variation does not become shorter than the shortest operation time. The operation speed variation instructions of the respective execution time variation steps are supplied to the facilities 1-7 at a time so that the operation speed varied at the found variation rate is reached.
