基于时间熵的生产系统精益管理导入效果评价

An Effect Evaluation of Lean Management Implementation in the Production System Based on Time Entropy

提出了生产系统时间熵的概念,对精益管理的导入如何改善生产系统中"人、机、料、法、环"五大要素继而影响生产系统时间熵进行了分析,并以科学性和实用性为原则,结合定性与定量的分析方法,构建了生产系统精益管理导入效果评价指标体系和基于时间熵的评价模型,为定量评价生产系统精益管理导入效果提供有效依据。利用所构建的指标体系和评价模型对一家胶管企业生产系统精益管理导入效果进行了量化评价,结合该企业精益管理导入实际情况,验证了所建指标体系和模型具有较好的适用性和有效性,为生产系统的精益管理导入效果评价提供了新的思路和方法.

The concept of time entropy of the production system is defined, and the way is analyzed in which the lean introduction improves the 5 major elements of production system, human resource, machine, materials, environment, to influence the response time of production system. Following the princi- ple of science and practicality, the appraisal indicators system of lean management implementation and an evaluation model based on time entropy are established, combining qualitative and quantitative analysis, which provides an effective basis for the effect evaluation of lean management implementation in the pro- duction system. Then the applicability and effectiveness of the indicators structure and mode is finally validated by a case study in a hose enterprise, based on the comparison between the evaluation results and enterprise actual situation. The research results provide a new methodology to evaluate the introduction of lean management in the production system.
