【摘要】：針對綜合評價選材中評價指標的權重難以合理確定這一問題,在分析現(xiàn)有組合賦權法的原理與不足的基礎上,提出了基于權重置信度的組合賦權法;以低溫存儲罐材料的選擇為例,運用此組合賦權法對分別由層次分析法、修正熵權法和BP神經(jīng)網(wǎng)絡法得到的8個評價指標的主觀權重、客觀權重和智能權重進行組合,并以所得組合權重,采用改進的理想解法對10種候選材料進行綜合評價。結果表明:此法得到全硬態(tài)301型不銹鋼是最佳的低溫存儲罐材料,與實際應用一致;說明采用基于權重置信度的組合賦權法來確定工程材料評價指標的權重是合理可行的。
[Abstract]:In order to solve the problem that the weight of evaluation index in comprehensive evaluation selection is difficult to determine reasonably, based on the analysis of the principle and deficiency of the existing combination weighting method, a combination weight method based on weight confidence is put forward. Taking the material selection of cryogenic storage tank as an example, the combined weighting method is used to combine the subjective weight, objective weight and intelligent weight of 8 evaluation indexes obtained by AHP, modified entropy weight and BP neural network respectively. Based on the combined weight, 10 candidate materials were evaluated by the improved ideal method. The results show that this method is the best material for low temperature storage tank, and it is reasonable and feasible to use the combined weight method based on weight confidence to determine the weight of engineering material evaluation index.
