The paper sketches a methodology analysis for the assessment of the urban land-use structure (ULUS) that adopting land value as the key criterion. The research includes two parts: firstly, introduce and analyze the mechanism of the ULUS self-adapting; then detailed models including pivotal formulas are developed for the simulation of the mechanism. The research can provide both theoretical analysis...
Because of the flaw that the risk rating evaluation of emergencies being the half quantitative and coarser, the paper uses the projection pursuit, the genetic algorithm and the simulated technology to establish the lightning disaster risk classification and rating process, the evaluation process reflects the strong objectivity and grade continuity. The paper researches the lightning disaster in Guangdong...
Based on the researches of water use efficiency in China and other countries, a water resource utilization efficiency assessment index system is proposed, which includes six kinds such as water use per 10,000 Yuan of GDP, removal variability of agriculture water resources utilization efficiency, per 10,000 Yuan of added industrial output value etc. By the cluster analysis of indicator data, it adopted...
In this paper, the effect against the precision of GM(1,1) model is analyzed. Then, the method of modificatory initial value based on GA is put forward. Moreover, the mechanism of Ameliorating GM(1,1) Model is showed. At last, the power quantity model of Shanghai city is built by applying the method. The application results show the effectiveness of the proposed approach.
A metaheuristic optimization procedure integrated with discrete event simulation (DES) is proposed in this work. The procedure was applied to the operation of the bus fleet owned by Al-Oroba Transportation Company in Amman, Jordan. The fleet operation was modeled and simulated using ARENA?? software. Two key performance indicators (KPIs) were defined to validate the developed model and characterize...
