Construction of Tourism Spatial Layout in Huaihua from the Recreational Perspective

With the investigation of the current situation of tourism activities and characteristics of recreational tourism spatial layout in Huaihua,problems in tourism spatial layout are pointed out,that is,indistinct division of tourism functions,comparatively bad relevance in the "point-axle" spatial structure,and comparatively bad horizontal and vertical coherence in tourism space.It is suggested to rationally construct tourism spatial layout in Huaihua City after the model of spatial layered structure of recreational sightseeing,that is,the model of setting Huaihua City as the center,and from the inside out with three layers of recreational island within the city,recreational sites around the city and recreational sites at towns and villages away from the city through the spatial layout of point,axis and plane.

An Improved Ant Colony Optimization Algorithm for Construction Site Layout Problems

Meta-heuristic algorithms proved to find optimal solutions for combinatorial problems in many domains. Nevertheless, the efficiency of these algorithms highly depends on their parameter settings. In fact, finding appropriate settings of the algorithm’s parameters is considered to be a nontrivial task and is usually set manually to values that are known to give reasonable performance. In this paper, Ant Colony Optimization with Parametric Analysis (ACO-PA) is developed to overcome this drawback. The main feature of the ACO-PA is the ability of deciding the appropriate parameter values within the predefined parameter variations. Besides, a new approach which enables the pheromone information value to be proportional to the heuristic information value is introduced. The effectiveness of the proposed algorithm is investigated through the application of the algorithm to the construction site layout problems taken from the state-of-art. Results show that the ACO-PA can reduce transportation cost up to 16.8% compared to the site layouts generated by Genetic Algorithms and basic ACO. Moreover, the effects of parameter settings on the generated solutions are investigated.

Discussion on construction and type selection of China high dams

At the beginning of 21st century, with the rapid and steady development of China economy, a lot of large scale hydropower projects with large dams from 200 m to 300 m high are being or to be built. China dam constructions are reaching the level of 300 m high arch dam, 250 high CFRD (concrete face rockfill dam) and 200 m high RCC (roller compacted concrete) gravity dam. Due to the safety and the economy, the type selection for high dams has become the key issue during the argumentation for the hydropower projects, and further efforts are still needed in this aspect for high dams. After reviewing the high dam constructions in China and abroad, authors proposed some advices for the selection of dam types, and hope that it can provide some helpful information for the researches and the design of high dams.

基于模型预测控制的多钢筋并行排布智能深化设计方法

传统钢筋深化设计的大量排布工作是基于手动或半自动化的方式完成的,时间及人工成本较高。目前基于单根钢筋的智能设计方法存在3个问题:同向钢筋没有共享机制,无法利用相似信息,造成大量重复性计算;钢筋之间不具备协同机制,无法保证钢筋前后左右间距的一致性;优化策略基于局部信息进行智能体轨迹规划,难以应对复杂和特殊的钢筋排布场景。为解决上述问题,提出基于模型预测控制(MPC)的多钢筋并行排布智能设计方法,以提高钢筋的排布效率及质量。MPC是一种可以兼顾全局信息和局部信息的寻优策略,通过滚动优化和最优解首元素的应用,提高钢筋应对复杂环境的能力,实现钢筋智能避障和长度优化。多钢筋并行排布策略采用领航跟随者模式实现信息共享和行为协同,利用同向钢筋的相似信息,可减少重复性工作并保证钢筋间距一致。为提高优化效率和质量,结合群体智能的优点进一步改进差分进化算法,并将其作为MPC的求解器。实验结果表明,通过与单钢筋排布方法在不同障碍物情形下的对比,提出的多钢筋并行排布方法能够有效提高钢筋排布的质量、优化效率和应对复杂障碍物场景,并以预制混凝土楼梯构件设计为示例,验证了所提方法的可行性和有效性。
