装配式建筑预制混凝土构件的布局优化

针对预制混凝土构件生产过程中模台利用率低的问题，提出一种高效的构件布局定序和定位优化方法。充分考虑构件生产过程中模台、模具、构件布局尺寸、操作空间等实际约束限制，以构件占用模台总长度最短为目标，建立基于最低水平线排布算法的数学模型；应用改进灰狼算法确定构件排布顺序，通过构件类型、尺寸信息、模台尺寸约束、模具数量约束等对待排构件进行编码，并设置追随系数和自由系数控制灰狼算法的收敛速度和收敛范围，经过多次优化迭代得出最优布局方案。在实证分析中，使用Python编程语言对布局优化模型进行编码，最终表明该方法能在较短时间内取得较好的优化效果，模台利用率显著提高，证明了方法的有效性和可行性。

Layout optimization of prefabricated concrete components in prefabricated buildings

In order to solve the problem of low utilization rate of formwork in the production process of precast concrete components, this paper proposes an efficient component layout sequencing and positioning optimization method. Firstly, the mathematical model based on the minimum horizontal line layout algorithm is established with the objective of minimizing the total length of the mould table occupied by the components, considering the actual constraints of the mould table, mould, component layout size and operation space in the production process of the components. Secondly, for the purpose of determining the sequence of component layout, this study uses the improved grey wolf algorithm and the components to be arranged are coded through component type, size information, and constraint conditions. Via setting the coefficient and free coefficient, which can control the convergence speed and convergence range of the grey wolf algorithm, the optimal layout scheme is obtained via multiple optimization iterations. Through empirical analysis, this method can achieve better optimization effect in a short time, and the utilization rate of the mold is significantly improved, which verifies the effectiveness and feasibility of the method.
