Problems solved by technology

[0008] 1) The RCPSP model is not complete enough and does not fully consider the 7 types of information for construction resource optimization
[0009] 2) The process of data integration and association is highly dependent on manual work, which is inefficient and error-prone
[0010] 3) Inability to make full use of existing engineering knowledge or experience such as standard processes
[0011] 4) The construction process of the schedule resource optimization model requires manual intervention, which is cumbersome and error-prone, and wastes a lot of time

Embodiment

[0160] 1) Data preparation

[0161] Using data preparation methods, the associated work package templates were created. Considering the difference in construction resources, the cast-in-place concrete construction work is decomposed into three work package templates: formwork engineering, reinforcement engineering and concrete engineering. At the same time, a work package formwork was created for the precast concrete walls and the precast concrete slabs respectively. Therefore, there are a total of 8 work package templates for test verification. Each work package template is composed of four parts, which are basic information, classification, process flow and resources. Among them, the classification and resource part are related to the information integration process. Currently there is only one building element code in the taxonomy, which is used for the first match during the core model integration process. The resource part includes several quotas, and each quota inclu...

Abstract

The invention relates to a method for automatic optimization of construction schedule resources based on a building information model, which includes the following steps: preparing a building information model with building element categories and main resource categories, and adding necessary information to a work package template database to form a number of requirements Work package template; data integration based on building component types and material types; use RCPSP constraints and objective functions to generate a schedule resource optimization model and solve it to complete the optimization of construction schedule resources. The invention can greatly improve the efficiency of data integration and construction optimization, and shorten the time for construction scheme optimization from a few days to a few hours.

Description

technical field [0001] The invention relates to a resource optimization method, in particular to an automatic optimization method of construction schedule resources based on a building information model. Background technique [0002] Resource-constrained project scheduling problem (RCPSP) is an important mathematical model for construction schedule resource optimization. RCPSP is an NP problem. Researchers use many heuristic algorithms to solve these problems, including heuristic algorithms based on priority rules such as simplified branch and bound method, local search technology, etc., and meta-heuristic algorithms, such as genetic algorithm, Particle Swarm Optimization and Tabu Search. For construction projects, many studies have established more complex problem models to meet actual needs, such as considering multi-projects, changing resource constraints, and simultaneously considering resource constraints and time-cost trade-off (TCT) issues. Generally speaking, these...
