Title Credibility Evaluation for Complex Manufacturing Simulation System
Abstract
How to build the credibility evaluation system for the pulse assembly line of aircraft and achieve the calculation is the major task we study in this paper. With the “Made in China 2025”plan is promulgated, many businesses pay attention to advanced manufacturing technology. The simulation on aircraft manufacturing area is exactly one branch of advanced manufacturing technology, simulation system and computer science have promoted that manufacturing informatization is the first step in validation. Although this technology is mature, it still be a hard field on how to evaluate the credibility of system simulation. The credibility of system simulation represents the evidence to substitution effect of prototype system to simulation system, scientificalness and completeness are the basis of evaluation system. Based on the above analysis, this paper proposed a method of manufacturing elements analysis. To the feature that aircraft manufacturing system is complex and enormous, building the evaluation system with scientific, comprehensive index. At last, we proved that system is effective through example verification.
