Analysis on the validity of the optimization of automobile OTD process structure based on structural-entropy model

OTD流程优化是汽车制造企业提高运作效率、降低成本、及时响应客户需求、提高综合竞争力的最佳途径之一.而对汽车OTD流程优化进行有效性分析是优化过程的必要环节.以BTO模式下某汽车制造企业OTD流程结构为研究对象,根据ECRS原则对现有流程结构进行优化,运用结构熵模型对优化前后OTD流程结构的时效熵、质量熵和有序度的值进行计算,并根据计算结果对流程结构优化的有效性进行评价.

The optimization of OTD process is one of the best ways for automobile manufacturing enterprises to improve operational efficiency, reduce cost, respond to customers＇ demand timely and improve comprehensive competitiveness. Meanwhile, the analysis on the validity of the optimization of automobile OTD process is a necessary part of optimizing process structure. For the OTD process structure of an automobile manufacturing enterprise under BTO, the existing process structure is firstly optimized based on the ECRS principle. Then,aging entropy, quality entropy and order degree of the OTD process structure before and after optimization are calculated by applying structure-entropy model. Finally, the paper evaluates the validity of the optimization of the process structure according to the calculation results.
