The Thin Coal Mining Equipment Multi-Objectives Fuzzy Decision Model
Qiang Zhang, Dafeng Tian · 2009
The thin coal mining equipment multi-rank choice and it is traditional choice method subjective capriciousness question, This paper is intended to discuss and analyze the assessment of mining method by the utilization fuzzy set and fuzzy mathematic theory, the equipment to carry on the multi-ranks to decompose, carries on the quantification recursive operation according to the normalizing formula, calculates all levels of membership function separately, thus it has established the thin coal mining way multistage fuzzy decision-making model.
