Appraisal of lean production's implementation

Integrating the advantage of traditional batch production and piece production, lean production is being widely adopted by enterprises under customer-oriented market environment. This trend requires the appearance of scientific appraisal to lean production implementation, because reasonable appraisal has great significance to smooth application of lean production. On one hand, through scientific appraisal the enterprise that has been applying lean production can recognize its lean degree and identify improvement direction, on the other hand, the enterprises that still hold wait-and-see attitude can know the value of lean production exactly. In this paper, the index system of appraising lean production is set up, including financial indexes and also non-financial indexes. The lean factors are correlated, leading to enterprise's unique competence, so in the process of appraisal we use ANP to fix the weights of indexes. After introducing the unascertained theory, we set up the model to appraise lean production's implementation. At last a case is shown using the model put forward in this paper.
