Research of Multi-Process Schemes Grey Fuzzy Synthetic evaluation Method

摘要

The main influencing factors on decision-making of process schemes are analyzed to set up a synthetic evaluation system involving processing quality, production cost, productivity effect and process flexibility. In view of the deficiency of traditional fuzzy synthetic evaluation, the method of qualitative index's quantification with fuzzy number is proposed. Establish the grey fuzzy synthetic evaluation model combining grey theory and fuzzy mathematics. The model here can ensure the impersonality and credit of the result, and the example proved this.
