METHOD AND SYSTEM FOR ESTIMATING TIME

摘要

PROBLEM TO BE SOLVED: To provide a method and system for estimating a time necessary for assembling a product taking dispersion of time into consideration at a design stage or a manufacturing process planning stage and the like before manufacturing the product. SOLUTION: An assembling time is estimated taking dispersion of assembling into consideration by estimating dispersion of assembling time using occurrence frequency of defective assembling. A defective assembly coefficient is estimated form an individual defective assembly coefficient for every standard assembly operation obtained by classifying assembly operations for a product, a first defect correction factor for every property of an individual assembling part composing the product, and a second defect correction factor for every property of a conjugate assembling part composing the product. The dispersion of assembling time is estimated by correcting the assembly time of the product based on the value of the defective assembly coefficient.
