震后建筑群修复施工阶段工程造价动态预控系统

震后建筑群修复施工阶段工程造价动态控制比其他阶段更具有变动性，需要高精度和高灵活性的预控系统的运用才能保证工程造价不出现偏差。在此文中，设计震后建筑群修复施工阶段工程造价动态预控系统。相关人员可在用户登录模块进入系统界面，在系统的工程信息管理模块中，采用改进遗传算法构建震后建筑群修复工程造价模型，完成震后建筑群修复工程造价动态预控系统的设计。实验结果验证，本文所设计的基于改进遗传算法的造价动态预控系统能够有效实现震后建筑群修复施工阶段的工程造价动态预控，伴随造价样本数目的增多，误差率会逐渐降低，预控性能较好；且预控灵活性始终大于95%，使用局限性仅有0.04，实用性较高，能够为震后建筑修复施工部门的工程造价控制给予借鉴。

A Dynamic Pre-control System for the Projected Cost of Post-earthquake Building Groups in Restoration and Construction Stages

Dynamic control of the projected cost of building groups in post-earthquake restoration and construction stages is more changeable than during other stages. Pre-control systems with high precision and flexibility are needed to ensure that there is no deviation in projected cost. In this paper, a dynamic pre-control system of projected cost in the restoration and construction stages of a post-earthquake building group was designed. Relevant personnel entered the system interface through the user login module. In the project information management module of the system, an improved genetic algorithm was used to develop the projected repair cost model of the building group as part of the overall system design. Experimental results showed that the dynamic cost pre-control system, based on an improved genetic algorithm, effectively realized dynamic cost pre-control in the restoration and construction stage of the post-earthquake buildings. With increasing number of cost samples, the error rate gradually decreased; moreover, the flexibility of pre-control was always >95%, and the use practicability was only 0.04. This system can provide a reference for cost control of post-earthquake construction.
