摘要
大型游乐设施的运行是一个动态管理过程,不但涉及设备本身,而且与人、环境等密切相关,针对这种特点,从人-机-环境-管理4个方面出发,建立了全面的大型游乐设施三级评价指标体系,并用AHP法来确定权重。因大型游乐设施评价过程中存在模糊性和不确定性,故综合采用基于AHP-灰色模糊理论的安全评价方法对某游乐园的大型过山龙进行安全评价,评价结果符合实际情况。
This article attempts to introduce a safety evaluation model for the large amusement rides based on the AHP-grey fuzzy theory. As is known, with the fast increase of the scale and number of large scale amusement rides, it has become an urgent problem to ensure the safety of such amusement rides in regard to the health and life, particularly for children. Based on the analysis of the characteristic features of the large amusement rides and the corresponding social and environment factors, we have worked out a safety evaluation model for the large amusement rides based on the investigation and interpretation of the corresponding factors, such as the factors of hu- man, machine, environment and management. To be exact, we have taken into account the 13 evaluation factors at the first level, and 66 evaluation factors as the secondary level. The entire safety evaluation index system has been divided into four sub-levels, such as the target layer A, the primary index layer B, the secondary index layer C, the tertiary index layer D. The weights of each evaluation factor can be calculated by using the AHP method. However, since the fuzzy and indefinite factors are the major problems for the safety evaluation of large amusement rides, we have introduced a grey fuzzy model to do such evaluations, in which three steps have been put forward by using the theory of grey fuzzy. First of all, all the evaluation factors of the tertiary index layer D are to be scored by the experts con- cerned. Secondly, the grey evaluation coefficients can only be worked out according to the established whitening function. Thirdly, a grey evaluation sample matrix has been established, so as to obtain the re- suits of the secondary evaluation factors only by multiplying the weight of the tertiary evaluation factors and the corresponding sample matrix. Similarly, the final evaluation results can be obtained through the re- peated calculation and evaluation. Based on the maximum member- ship grade and the determination of the safety levels, we have
