【摘要】：交通工程项目建设施工是一项复杂的系统工程,其内部各组成部分之间相互联系又相互制约,关系错综复杂。其施工方案的优劣直接影响到项目的质量、安全、环境、进度、成本等目标的实现,工程项目施工方案在工程施工中占有重要地位。对交通工程施工方案的优选涉及面广,是一个包含有定性和定量指标的多因素和多目标的复杂系统的决策问题。针对具体的交通工程项目的特点,建立科学的施工方案优选决策模型,从众多可行的施工方案中选择适合工程项目的最优施工方案,具有重要的理论研究和实际应用价值。本文的主要关键技术是网络计划技术与虚拟技术、模糊综合优化、遗传算法的求解在交通工程建设施工方案比选的综合运用,根据交通工程施工方案的特点,采用定性和定量相结合的指标,利用多目标决策方法来进行方案优选的决策,建立了基于工期-成本-质量-安全-环保的模糊群决策模型；将施工网络计划技术、模糊综合优化和遗传算法的方法理论应用到交通工程建设项目施工方案比选优化中,以排梁垭隧道为例,考虑施工工期、成本、质量、安全、环保指标五个施工重要目标,定义模糊多属性优属度,并利用直觉模糊集进行评价,建立综合工期-成本-质量-安全-环保的模糊优化群决策模型,并用遗传算法进行求解,得出最满意作业模式组合下,从而对排梁垭隧道的施工方案进行决策。最后应用虚拟可视化仿真技术,对排梁垭隧道施工的重点工序进行虚拟可视化仿真研究,可以得到合理可行的施工方案,为施工方案的优选提供了依据,实现了工期、质量、成本、安全、环保等目标的均衡优化,有效提高了工程项目的经济效益和社会效益。
[Abstract]:The construction and construction of traffic engineering project is a complex system engineering, and its internal components are interrelated and restrict each other, and the relationship is complicated. The quality, safety, environment and progress of the project are directly affected by the merits and demerits of the construction scheme. With the realization of cost and other objectives, the construction scheme of engineering project plays an important role in the construction of the project, and the optimal selection of the construction scheme of traffic engineering involves a wide range of aspects. It is a decision problem of a complex system with qualitative and quantitative indexes. According to the characteristics of specific traffic engineering projects, a scientific decision model for optimal selection of construction schemes is established. It has important theoretical research and practical application value to choose the optimal construction scheme from many feasible construction schemes. The main key technologies of this paper are network planning technology and virtual technology, fuzzy comprehensive optimization, and the comprehensive application of genetic algorithm in the comparison and selection of construction schemes for traffic engineering construction, according to the characteristics of traffic engineering construction schemes. The fuzzy group decision model based on time limit, cost, quality, safety and environmental protection is established by using qualitative and quantitative indexes and multi-objective decision making method. Fuzzy comprehensive optimization and genetic algorithm method theory are applied to the comparison and optimization of construction schemes of traffic engineering construction projects. Taking Pailiangya Tunnel as an example, five important construction objectives are considered, such as construction period, cost, quality, safety and environmental protection index. The fuzzy multi-attribute optimal degree is defined and evaluated by intuitionistic fuzzy set, and a fuzzy optimization group decision model is established, which integrates duration, cost, quality, safety and environmental protection, and is solved by genetic algorithm. Finally, the virtual visual simulation technology is used to study the key construction process of Pailiangya tunnel, and the reasonable and feasible construction scheme can be obtained. It provides the basis for the optimal selection of the construction scheme, realizes the balanced optimization of the objectives of time limit, quality, cost, safety and environmental protection, and effectively improves the economic and social benefits of the project.
