The invention provides a technology capable of calculating task time of for assembling a part. The computer device of the invention stores a parts list storing parts and part quantity to be used in producing a product, a parts-assembly task master storing, on a by-part basis, task classification of task for assembling the part, a task time master storing task time for size and/or weight of part and task classification, means for determining the task classification by searching for the parts-assembly task master, using as a key, the part stored in the parts list, and a means for determining task time by searching for the task time master, using as keys, the part and task classification searched. The calculating device enables the process of planning a task assignment be initiated when the parts list is decided on, and the duration from the completion of product design to the start of mass production can be greatly shortened.
