Abstract
Because the traditional logistics transportation cost optimization algorithm of prefabricated building components has the problems of long transportation time and high transportation cost, a logistics transportation cost optimization algorithm of prefabricated building components for project management is proposed. A project management oriented prefabricated building component management system is built, the logistics and transportation process of prefabricated building components are analyzed, and the logistics vehicles of prefabricated building components under the time window are scheduled. According to the scheduling results, through the waiting unloading time cost, transportation cost, and penalty cost, the total cost objective function is built to obtain the optimal cost. The simulation results show that the proposed algorithm has the shortest logistics transportation time and the lowest transportation cost.
Highlights
With the progress of the times and the development of economy, the development of construction industry has ushered in new opportunities and has become an important driving force for China’s economic improvement. e traditional cast-in-place construction mode can no longer meet the needs of diversification, high safety, and low energy consumption of current building production, while the energy-saving, labor-saving, safe, and efficient prefabricated buildings gradually replace the traditional production mode [1]
In view of the problems in the above algorithms, this paper proposes a project management oriented logistics transportation cost optimization algorithm for prefabricated building components, and the simulation experiments verify that the algorithm has low cost and high operation efficiency, which lays a foundation for the development of logistics transportation
Transportation Cost. e transportation cost of prefabricated building component vehicles refers to the fuel cost and temporary maintenance cost consumed by vehicles starting from the component processing plant, passing through various construction sites, and returning to the component processing plant, which is directly proportional to the total distance traveled by vehicles. e longer the distance, the higher the cost. erefore, the main factor affecting the transportation cost is the total distance of vehicles, which puts forward requirements for the vehicle dispatcher of the component processing plant to make scientific and reasonable vehicle time and route arrangement before vehicle transportation. en, the transportation cost generated during vehicle scheduling of prefabricated building components can be expressed as n
Summary
With the progress of the times and the development of economy, the development of construction industry has ushered in new opportunities and has become an important driving force for China’s economic improvement. e traditional cast-in-place construction mode can no longer meet the needs of diversification, high safety, and low energy consumption of current building production, while the energy-saving, labor-saving, safe, and efficient prefabricated buildings gradually replace the traditional production mode [1]. I.e., distribution vehicle transportation, cold chain energy consumption, litchi loss, and time window punishment, as the research object, the cost model of each factor is constructed, and the objective optimization function of cost optimization in the process of litchi cold chain logistics distribution is determined. Literature [6] proposed the optimization algorithm of logistics distribution path of fresh food cold chain, established a new cost and constraint model, and gave the optimization method using simulated annealing algorithm. In view of the problems in the above algorithms, this paper proposes a project management oriented logistics transportation cost optimization algorithm for prefabricated building components, and the simulation experiments verify that the algorithm has low cost and high operation efficiency, which lays a foundation for the development of logistics transportation.
