Abstract
In order to avoid accidents and improve the level of laboratory safety management in universities, a laboratory safety assessment method based on entropy weight method, analytic hierarchy process and unascertained measure theory is put forward. The laboratory safety assessment index system is established by selecting eight assessment indexes such as hazardous chemicals management, instrument and equipment management and personal protective equipment management; The comprehensive weight of the assessment index is determined by combining the combination weighting method of analytic hierarchy process (AHP) and entropy weight method (EW). According to the principle of maximum membership degree, the safety grade of university laboratory is determined, and compared with the actual results. This work indicated that this innovated method can reasonably evaluate the current situation of laboratory safety, and it can provide a reference for strengthening laboratory safety management.
Highlights
Accidents, in recent years, occurred frequently in numerous college laboratories and caused significant losses and negative social influences[1]
The comprehensive weight of the assessment index is determined by coupling the subjective weighting method Analytic Hierarchy Process (AHP) and the objective weighting method Entropy Weighting (EW)
The entropy weighting method (EW) is an objective weighting method that via entropy νij to measure the amount of information and determine the importance of assessment indicators
Summary
In recent years, occurred frequently in numerous college laboratories and caused significant losses and negative social influences[1]. A number of hazardous materials in university laboratories is less than industry, safety problems are always difficult to properly solve due to the high mobility of personnel, insufficient individual experience and incomplete safety management system. Good results have been achieved in research and establishment of the laboratory safety assessment system[6]. This study consulted related materials, found that they are related to the safety of university laboratories. The laboratory safety level assessment of colleges usually adopts a checklist scoring method, but the scoring information in the checklist is mostly uncertain. This study can adopt EW-AHP and unascertained measurement theory and assessment index system to enrich the safety assessment theory and provide a reference for improving the safety level of universities laboratories
