Problems solved by technology
"Because there is a lot of ambiguity involved in site selection, if GIS technology is used, these analysis problems closely related to spatial factors can be solved well, such as Tan Qinwen, Yin Guangzhi, He Youfang, etc. in Document 1 "GIS and Application of Fuzzy Optimization Theory in Tailings Dam Site Selection” (Journal of Natural Disasters, 2009, 18(4)), the application of GIS and fuzzy optimization theory to site selection of tailings dams has achieved good results, but the calculation is more complicated

Embodiment Construction
[0021] figure 1 It is a decision-making algorithm in tailings dam site selection; a decision-making algorithm in tailings dam site selection of the present invention includes the following steps:
[0022] (1) Screening factor indicators, the set of selected factor indicators is Q={q 1 ,q 2 ,q 3 ,q 4 ,q 5}, where the factor index: q 1 is the "maximum storage capacity" (10 4 m 3 );q 2 is "dam height" (10 4 m 3 );q 3 for the "footprint" (10 4 m 2 );q 4 is "conveying distance" (km); q 5 The pair is "dam volume" (10 4 m 3 );
[0023] (2) Extracting alternatives to form an alternative set A={A 1 ,A 2 ,A 3 ,…,A i}, A i is the i-th alternative;
[0024] (3) Establish the most ideal scheme B; in the optimal site selection of tailings dam, the requirements for the characteristic values of each factor index of the ideal scheme are different. Factor indicator "maximum storage capacity" q 1 The bigger the better; the factor index "dam height" q 2 The smaller the...

The invention discloses a decision algorithm for site selection of a tailings dam. The decision algorithm comprises the following steps: according to relative popularization of the Vague set theory, the decision algorithm is applied to the space decision of site selection of the tailings dam. The invention provides a new research method and a new computational formula, original data are changed into Vague data, Vague sets of various alternative schemes and the Vague set of the most ideal scheme are obtained, the similarity among the Vague sets is calculated, Vague space decision is carried out, and then the optimal scheme can be obtained. The method disclosed by the invention is used for developing the similarity formula among the Vague sets, and is also a direction for applied research of the Vague sets. The Vague space decision algorithm provide a new method for problems such as optimized site selection of the tailings dam, and has important social benefits and economic value.
Description
technical field [0001] The invention relates to a decision-making algorithm in tailings dam site selection, which is applied to tailings dam site selection for spatial decision-making problems by utilizing the relevant extension of Vague set theory. It belongs to the field of field surveying and mapping, artificial intelligence and data analysis technology. Background technique [0002] Site selection refers to the process of selecting a location for one or more site selection objects in a certain geographical area, so that a certain index or comprehensive index can be optimized. Spatial location selection can be seen everywhere in real life, and the range of location objects is very wide, such as hospitals, schools, fire stations, supermarkets, logistics centers, landfills, bus stations and airports. With the development of society and economy, various factors affecting site selection are more complicated than ever, and it is more and more important and difficult to scient...
