Fuzzy Assessment

Tower crane belongs to high risk equipment in the construction site. Evaluating safety statement of tower crane is a subject of the technical field. The paper setups a new way to evaluate the safety statement of tower crane by means of fuzzy assessment theory. Membership functions have been established for describing the influencing factors of tower crane safety. Fuzzy comprehensive assessment model for evaluating tower crane safety statement has been established. Finally an example for illustrating the method of using the fuzzy comprehensive assessment to analyzing the tower crane safety statement.

Environmental Landscape

Based on the established index system of Community environmental landscape, the Community environmental landscape was evaluated by the second level fuzzy comprehensive assessment model and its quality was divided into outstanding, good, general, poor and bad five grades. In this paper, the Community environmental landscape was comprehensively analyzed by ascertaining the weight coefficient of index and membership functions. Take Zhengzhou People's Community for example, this paper puts forward a new idea of evaluating the Community environmental landscape.

Hierarchy Process

Based on the function level of a gas turbine generator, this paper presents a method for the quantitative assessment of the health condition of a gas turbine generator by using fuzzy comprehensive assessment (Fuzzy) and an analysis hierarchy process (AHP). First, the failure mode, effects and criticality analysis method (FMECA) is used to construct the assessment framework and obtain the indicator set for the health assessment. The membership degree of each indicator is realized by using triangular and trapezoidal membership functions. Second, the fuzzy comprehensive assessment model with analysis hierarchy process (Fuzzy-AHP) is established to implement the quantitative assessment of the health condition of the gas turbine generator, and the man-made influence on the weight assignment is decreased. Finally, an example of a three-shaft gas turbine generator health assessment is provided to validate and prove that the method is effective and feasible.

Grey Correlation Analysis

This paper proposes a hybrid evaluation approach combining fuzzy comprehensive assessment method and AHP that measures the safety performance of construction site. The weight of each index was calculated through AHP model which use in fuzzy comprehensive assessment, and then the safety level of construction sites was determined by multi-layer fuzzy comprehensive assessment technique. In order to find out the main causes of safety level of construction site’ changes, the grey correlation analysis was used to quantify the influence degree of each factor of safety level of construction site. The effectiveness of our methodology was verified with an empirical study by using the data of 3 construction sites we investigated. The results show that this approach can be an effective tool to predict the safety performance of construction projects sites, which is useful to provide a scientific basis for the management and decisions of accident prevention.
