基于GA-ANN的建筑生产安全评价方法研究
摘要:针对目前我国建筑生产安全评价技术的不成熟和欠科学性的现状,本文分析和综合了目前安全评价技术,结合建筑业特点,提出了基于GA-ANN的建设生产安全评价方法,并对该评价模型的原理、方法及算法进行了研究。首先,结合建筑生产的特点建立影响建筑安全生产的风险因素指标体系,然后建立度量建筑生产安全的评价指标,最后,利用收集的样本集训练GA—ANN,待误差满足要求后,即可运用训练成功的神经网络进行安全评价。

Abstract: For the Safety Evaluation method of construction Industry is lack of ripeness and science, the safety Evaluation method of construction is put forward based on GA work according to the characteristic of construction industry, analyzing and synthesizing safety evaluation method at present, Then the theory, method and arithmetic of the evaluation model are studied. At first, the index system of risk factors influencing construction industry safely is proposed, according to the characteristic of construction industry, then the Evaluation index of measuring the degree of safety in construction production is put forward, At last, GA-ANN is trained by the training samples collected. As the errors are settled for the aims, the GA-ANN would be applied for the evaluation of safety in the construction industry.
