In this paper, we not only analyze the current characteristics of the urban rail transit affiliated commercial circles based on their operating status, but also propose measures on optimizing operating status of its logistics system, suggesting that the whole commercial circles should be jointed for the establishment of a unified logistics center, in which goods are distributed and recycled through...
From the aspect of methods, technique and data, bringing forward that the spatial organization of FNLCR has spatialized and digitalized characteristics. In the research, the main requirement of data includes the data of 2D vector graphics, RS image, the data of digital elevation models, the data of various statistics, and the data of 3D urban graphics and texture, etc.. Bringing forward the basic...
This paper establishes a three-stage reverse supply chain model which includes one manufacturer, one retailer and one agent who helps the manufacturer to recall waste materials. Besides, this paper assumes that the numbers of this reverse supply chain are all based on the Stackelberg game model. Under the condition of stochastic market demands, this paper analyzes the optimal pricing and order strategies...
Dispatching speeds of certain substations exert a great impact on the power supply of both residents and industries and the security of power grid. Choosing substations in Guangdong Power Grid as the research object, this paper researches on the operating process of dispatching instructions with Monte Carlo method. By comparing the statistical indicators, such as the probability of waiting, the average...
Based on the analysis of the development of Guangzhou economy and logistics parks, this paper introduces the BOT project mode of Guangzhou logistics parks. Based on the BOT, this paper analyzes the risks which the Guangzhou logistics parks meet, and designs an evaluation system. And then, through grid method and fuzzy Borda number analytical method, this paper analyzes the BOT project risks of Guangzhou...
The traditional group decision-making method mostly is static aggregation method which scientifically defines the decision weighted vector of each decision makers. In fact, the group decision making convergence is always a dynamic process. The preferences of decision maker are dynamic changing in this process, it is more realistic to apply the dynamic model to consider the consistence convergence...
In supply chain operations, there may be many disruptions, which cause much costs and reduce supply chain performance. So, it is necessary for corporations to understand the anti-disruption capability of the supply chain which they participate in. This paper designs a new evaluation system which is more appropriate to test the supply chain anti-disruption capability. And according to the proposed...
This paper describes the simulation modeling for planning for the efficient transportation of patients following a disaster. Research was performed in an effort to predict the consequences of conceivable scenarios. Discrete-event simulation modeling provided an effective supplement to regular drill procedures when training emergency medical services personnel. Initial performance of the redesigned...
High traffic always leads to descending quality of communication, higher lost call rate and increased complaints with the expansion of regional customer scale. Therefore, it is necessary to improve communication quality by enlarging the capacity of base station with the consideration of utilization efficiency of network resources. The difficulty of decision on PHS network capacity enlargement increases...
