Optimization decision-making method for concrete transportation queuing networks during high arch dam engineering construction

Abstract

The invention belongs to the technical field of engineering management, and discloses an optimization decision-making method for concrete transportation queuing networks during high arch dam engineering construction. The concrete transportation queuing networks can be dynamically optimized by the aid of the optimization decision-making method during high arch dam construction. The method includes steps of A, describing relevant uncertain parameters by the aid of fuzzy random numbers; B, computing system state transition probabilities of the transportation networks; C, building multi-objective and multistage decision-making optimization models; D, equivalently transforming the models to form solvable multistage decision-making optimization models; E, solving the models by the aid of particle swarm optimization algorithms on the basis of paired processes. The optimization decision-making method has the advantage of applicability to improving the construction efficiency and reducing the running cost during high arch dam engineering construction.

Description

technical field [0001] The invention belongs to the technical field of engineering management, and in particular relates to an optimization decision-making method for concrete transportation queuing network in the construction of high arch dam engineering. Background technique [0002] Concrete construction in the construction of high arch dams consists of three systems: concrete production, transportation and pouring, such as figure 1 shown. In the construction of high arch dams, often only one concrete production system is required (see figure 1 dotted box in the middle of the lower part). The concrete production system generally consists of multiple concrete mixing plants (see figure 1 circle in a dotted box). dump truck (see figure 1 medium white small rectangle) line up to load concrete at the concrete mixing plant, and then transport the heavy load to the unloading point (see figure 1 dashed triangle) for use in concrete placement systems (see figure 1 upper dot...
