That led them to look director, Process Technology Department, for a better method, which turned out to Engineering Planning and Design Institute be Tecnomatix® software with its Variation I at Chery. “At the initial design stage, they Analysis (VSA) component, a powerful can analyze whether the structure, dimensional analysis tool used to simulate manufacturing and assembly processes and predict the amounts and causes of variation. “After evaluating a number of possibilities, we were impressed by the powerful functionality of Tecnomatix, as well as by the fact that Siemens has an engineering team in North America dedicated to dimensional analysis,” says Shiqiang. “We were also aware that Siemens has been collaborating with Ford over the years and we believed that they could provide us with valuable assistance. Those are the reasons we chose Tecnomatix.” Predicting problems before they happen Chery uses Tecnomatix Variation Analysis software for manufacturing and assembly workflow simulations. The software virtually performs the assembly process and builds the dimensional chain for the product. Using the Monte Carlo principle,
