Sustainable Laboratory Evaluation Method Based On Pythagorean Fuzzy Set

Looking back on the 40 years of reform and opening up,China has not only achieved positive economic results,but also with the development of biochemistry,electronics and computer education in recent years,the environmental pollution problems of schools at all levels and research rooms in some units have gradually emerged.However,with the continuous development of education in chemistry,electronics,computer and other disciplines,environmental pollution problems in universities,middle schools and laboratories of scientific research institutions gradually emerge.Sustainable development has been written into the 13 th Five-Year Plan of many industries in China.It is noted that the focus of sustainable development in China is mostly on industrial enterprises.This paper introduces the concept of sustainable development into laboratory management.As the three pillars of sustainable development,there are inevitably contradictions and incompatibilities among economy,society and ecology.Compared with other fuzzy sets,Pythagorean fuzzy sets can well depict such contradictions and incompatible information.In view of this,based on the principle of sustainable development and the Pythagorean fuzzy theory,a series of methods to sustainable laboratory evaluation have been proposed in this paper.After nearly three years of efforts,some defects in the corresponding existing algorithms have been improved.The innovation of this paper is mainly divided into three aspects: concept,theory and method.1.Concept innovation: The concept of sustainable development is introduced into laboratory evaluation,and Pythagorean fuzzy set is introduced to model the problem of sustainable laboratory evaluation in view of the conflict among the three pillars of sustainable development: economy,society and ecology.2.Theoretical innovation: In view of the conflict,interaction and complexity of lab evaluation of sustainable development and the defects of existing Pythagorean fuzzy language set,a new Pythagorean fuzzy language set is improved and put forward.3.Method Innovation: The evaluation index system of sustainable laboratory was constructed by using statistical method and expert evaluation method,and different evaluation methods of sustainable laboratory were given step by step according to different situations and various methods.Through the analysis and comparison of examples,it is proved that the proposed algorithm model is reasonable and effective.Moreover,it is worth noting that the new evaluation model of sustainable laboratory,which takes into account economic,social and ecological factors,is more in line with the sustainable development concept of ecological and energy conservation in China,and provides a new perspective for the application of Pythagoras fuzzy theory and laboratory evaluation.
