Simultaneous optimal selection of design and manufacturing tolerances with different stack-up conditions using scatter search

摘要: The allocation of design and manufacturing tolerances directly influences the cost functionality a product. Traditionally, it is carried out in two phases; CAD CAPP, sequential manner. This approach has drawbacks more lead-time sub-optimality. present work reports on procedure to simultaneously allocate both based minimum total cost. optimization model for tolerance non-linear multivariable problem. Since such problem may have noisy surface, there need apply an efficient global technique. In work, scatter search, one recently emerged techniques area metaheuristics, applied successfully determine optimal at An example taken from literature explain proposed methodology. results exhibit effectiveness algorithm over other methods.
