Research on analysis methods for after-sales business in engineering changes process
For manufacturing enterprises,it is common to make engineering changes to components after mass production. If the substitution relationship of components is not analyzed in the early stage of engineering changes and the follow-up strategy for after-sales parts is determined in advance,it may lead to the inability to purchase original parts,thereby affecting after-sales maintenance and customer satis-faction. Therefore,based on four different types of engineering changes,different analysis methods are proposed. Detailed analysis and judgment can be conducted during the early review of engineering changes,and measures can be taken to avoid adverse effects on the after-sales market.
