Embodiment Construction
[0087] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0088] The process of model application and effect verification is as follows:
[0089] Taking the option and arrangement of group towers of an engineering project as an example, the optimization effect of this optimization model is verified by comparing the usage costs of group towers in the initial scheme and the optimized scheme. Project overview such as figure 1 Shown: The single-story building area is 39276.5 square meters; it includes 77 construction sections; each construction section selects a material demand point; the service life of the tower crane is 12 months. The alternative tower cranes include 4 models, and the specific performance indicators and cost parameters are shown in Table 1.

The invention discloses a tower crane model selection and arrangement optimization modeling method based on hybrid shaping planning, and belongs to the field of engineering construction management. Aiming at the construction site tower crane model selection and arrangement problem, the invention provides the construction site tower crane model selection and arrangement optimization modeling methodbased on the mixed integer linear programming theory, and the transportation efficiency of the tower crane is ensured by reasonably allocating the hoisting tasks of the overlapping area of the working range of the tower crane, so that the reference is provided for the construction organization planning work. On the basis of the hybrid shaping linear programming theory, the construction site towercrane model selection and arrangement optimization modeling method is provided under the condition that the influence of reasonable allocation of hoisting tasks in a mutual interference area of towercranes on the utilization rate of the transportation capacity of the tower cranes is considered, and the optimization effect of the model is verified through case comparison.
Description
technical field [0001] The invention relates to a method for optimizing the type selection and arrangement scheme of a tower crane at a construction site, belonging to the field of engineering construction management. Background technique [0002] As an important industry supporting my country's economic development, the construction industry has an average annual growth rate of about 10.85% in the past five years, but the profit rate of construction enterprises has only increased from 3.48% to 3.61%. According to the research on site layout in the manufacturing industry, proper site layout can reduce material transportation costs by 20% to 60%. Since the selection and arrangement of tower cranes is an important content in the layout of the construction site, optimizing the selection and arrangement of tower cranes has a strong role in reducing construction costs. [0003] As the core machinery in the vertical transportation scheme of the construction site, the tower crane ...
