Adaptive design change considering making small impact on the original manufacturing process

Abstract

In the development of complex products, there are various design changes from the product itself, costumers need, and manufacturing environment issues. However, few references mention the design changes caused by abnormalities during trial production or even actual manufacturing. When faced with redesign and reproduction in customized production, it is impossible to stop all equipment to solve the product problem, which will cause great losses. Considering the way to ensure the completion of design changes while minimizing the impact on the overall production has certain research significance. This paper focuses on the factors that lead to design changes during manufacturing and highlights the importance of real-time information feedback for redesign. Attentions are paid to the response of components to changes. The changing ability of product components is evaluated based on the strong correlation between components through complex network. Under different size and scope of the initial change, the completion degree of the whole product is studied, based on which, the secondary feedback from the redesign to the original manufacturing is quantified. This method provides managers with an adaptive design change scheme suitable for the current customized manufacturing state with small impact on the original process scheme. Also, the maximum change bearing capacity under the current state could be obtained.
