Abstract

The invention provides a construction site plane arrangement method based on a random strategy and a multi-objective optimization algorithm. The method comprises the following steps: taking the position coordinates of the upper left vertex of a rectangle corresponding to a to-be-arranged facility as a decision variable, carrying out random strategy arrangement, and carrying out anti-overlapping constraint on a randomly generated arrangement scheme to form an initial population of the multi-objective optimization algorithm; allowing the randomly generated arrangement position coordinates of facilities to participate in iterative operation of the multi-objective optimization algorithm in a real number encoding form as genes on chromosome loci, and carrying out self-adaptive algorithm improvement on crossover and mutation operation to finally obtain an optimal construction site arrangement scheme. The defects that a conventional construction site arrangement strategy is liable to lose a solution and a local optimal solution are overcome, and the global optimization characteristics of an intelligent algorithm are fully realized; and a plurality of engineering actual requirements are started from, the final site arrangement scheme does not singly meet the requirement of one aspect any more, and various functional requirements of the site arrangement scheme are improved on the whole.

Description

technical field [0001] The present invention relates, in particular, to a construction site layout method based on a random strategy and a multi-objective optimization algorithm. Background technique [0002] At present, the intelligent construction site layout method is mainly to establish the target model of the site layout, with the help of the intelligent optimization characteristics of existing intelligent algorithms, such as genetic algorithm, ant colony algorithm, particle swarm algorithm, etc., to finally meet the requirements The optimal site layout plan for the target; before the algorithm is used in this type of method, the layout mode of the facilities in the site needs to be determined first, and then the algorithm performs intelligent planning of the facilities to be arranged according to the layout mode. The existing layout mode of the facilities in the venue mainly adopts the layout strategy of automatic line wrapping, that is, first number the facilities to ...
