The Vehicle Scheduling Of Ready-Mixed Concrete Trucks And Layout Optimization In High-Speed Rail Construction

Concrete truck scheduling is a widespread problem in the large building construction. If processing is not good, the impact of small words would influence construction uniformity, reduce the economic benefit of construction enterprises, high impact would cause the contradiction of construction operation chaos and construction between units. Mathematics, concrete truck scheduling is a kind of mixed integer planning problem. In the academic structure it is a NP-hard problem. It is very difficult to solve. In High-speed Rail construction, a huge amount of concrete will be used. The construction site space is tens of kilometers at least. Climatic conditions changes with the seasons and road conditions (eg, uphill, downhill, sharp turns, cliffs, potholes). Concrete truck scheduling has many peculiarities from from respect to general building.Based on the reference of previous related work, I specifically carried out the following three aspects: First, I established the optimization scheduling/concrete tank truck delivery model, which considered the factors of tanker scheduling. By adjusting the time of arrival rate, it can better inclusive High-speed Rail construction road, traffic capacity, climate and other factors.Second, I use PPSO in multi-objective case, concrete tanker scheduling problem is solved, the results in a high-speed railway construction site verified.Third, I use VC++to build a concrete tanker optimal scheduling/distribution application software, which has the basic elements of practical applications.
