Embodiment Construction
[0040] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:
[0041] A factory produces three types of products A1, A2, A3, in order to select a product with the best quality, the factory set up a team composed of three experts E1, E2, E3, for the three types of electromagnets from The four characteristics of failure rate, reliability, magnetic field strength, and electromagnet attraction are collected through statistical and experimental methods to collect corresponding data, and finally use this patent to select the most suitable product.
[0042] According to the formulas (37) and (38), it can be seen that the reliability has a great relationship with the failure rate and running time, especially the reliability. figure 2 ;
[0043] It can be seen in the figure that as the running time increases, the reliability gradually decreases. When the running time exceeds 500 hours, the reliability decreases faster. For the...

The invention discloses an electromagnet multi-quality characteristic decision-making method based on an LECTRE and VIKOR method, and relates to the field of electromagnet quality decision-making, andthe method comprises the steps: A, studying and judging electromagnet multi-quality characteristics, and analyzing the relationship with external factors; B, obtaining an intuitionistic product according to the multi-quality characteristics, calculating membership through a membership function, and constructing a decision matrix according to the divided membership ranges; C, constructing a mathematical model by using positive and negative ideal solution ideas in combination with expert sequence weight constants, and solving the model by using LINGO software to obtain expert weights; D, aggregating the multi-mass characteristics of the electromagnet through a DINFWGA operator, and performing data comparison on LECTER; E, according to the membership degree, the non-membership degree and thehesitation degree of each quality characteristic, performing consistency and inconsistency comparison by an ELCTER method according to a preset standard; F, calculating the weight of each index; andG, calculating to obtain a compromise score Q value of each electromagnet, and sorting according to the Q values. The invention has the advantage of being good in objectivity.
Description
technical field [0001] The invention relates to the field of electromagnet quality decision-making, in particular to an electromagnet multi-quality characteristic decision-making method based on ELECTRE and VIKOR methods. Background technique [0002] An electromagnet is a component that can produce a magnetic field effect after being energized. Its most notable advantage is that its magnetic presence and strength can be controlled by turning on, off, and the magnitude of the current. It is widely used in important fields such as transportation, water conservancy, shipping, and electronic and electrical manufacturing. Therefore, the role of electromagnets It is particularly prominent, and it is of great significance to improve its quality level. The overall mass of an electromagnet is described by a multi-mass property. With the increasing frequency of electromagnet use, decision-making on multi-quality characteristics has also become a focus of society. The operating stat...
