In terms of the retail commodity sale forecast, people did more in particular aspect with commodity's single sale attribute such as the sale volume, the sale money, the season factor, but all has not considered the most important factor-profit, the profit is the key factor of retail enterprises winning the survival and development. However, such a one-sided analysis is not conducive to assist the...
Many existing implementations of TCP congestion control algorithms are mainly designed for public internet, which are needed to consider RTTs fairness and bandwidth and time-delay of unknown network. But these principles have shortcomings in data transmission in long-distance and high bandwidth-delay private network, which seriously affects the transmission performance and bandwidth utilization. Based...
Data creditability plays a very important role in the complex system simulation creditability. From the point of how to evaluate and improve the complex system simulation data creditability, the concept of the data quality modeling is advanced and the three-dimension data quality modeling space is founded. Based on which, a multiple attributes decision making theory based data creditability evaluating...
ArcGIS Geoprocessing is an important part of ArcGIS, which is a large-scale geographic information system software launched by ESRI corporation. The ArcGIS Geoprocessing provides an application-oriented and Process-oriented spatial analysis modeling method, so it's a very useful assistant decision-making and programming tools. Project Site location is a typical multifactor comprehensive evaluation...
Hydrologic model setup is an important process in the whole model simulation. This study introduces an approach for hydrological simulation analysis based on extracting watershed features from DEM using Arc Hydro Tools. This method consists of two steps: firstly, extracting watershed features from DEM using Arc Hydro Tools. Then, process hydrological simulation analysis with hydrologic model HSPF...
Extracting watershed features from DEM (Digital Elevation Model) is a very important task in Hydrologic study, and also it is the pre-process of hydrological simulation analysis. This paper introduces a very useful method for Hydrological simulation analysis based on extracting watershed features from DEM using Arc Hydro Tools. Arc Hydro is a geospatial data model especially GIS for Water Resources,...
