To reduce labor required for work scheduling by automating work scheduling for plural robots.
For spot welding by means of plural robots, welding spot information expressed by the respective shaft values of robots is inputted from robot emulator data 41 and according to previously set limitation conditions, the grouping of welding spots is performed (a2). It is previously discriminated whether or not interference is to generate between the groups and the result is outputted as group data 43. For solutions such as the distribution of groups to the respective robots, the operating order of groups for respective robots and the bonding in the welding order of respective welding spots in the groups, initial values are generated while using the approximate solution method of the traveling sales-man problem (a3). Concerning the solution, an optimizing method based on an SA parameter 45 is applied and while evaluating cycle time considering the interference, the solution is improved (a4).
