However, this method seems to be unsuitable when the demand points increase to a certain large extent. The present work attempted to convert the problem of distribution area demarcation into a localized problem of warehouseing and networking, and tried to establish district-based planning mode based on location based heuristic (LBH). Two methods were used in this study: 1) the manual method to construct the mathematical model and conduct simulation; 2) the automatic method using TransCAD software of geographical information system (GIS) for simulation. By comparing the effects of the two methods, the research provides theoretical support for business proprietors to demarcate the distribution area rationally with the application of GIS system. The results show that GIS has very good graphics construction function to replace complex text, and the automatic demarcating mode with human-machine interaction provides a good business decision-making support.展开更多

First, it calculated the fuzzy similarity among a certain sensor＇s measurement values and the multiple sensors＇ objective prediction values to determine the importance weight of each sensor and realize multi-sensor data fusion. Then according to the determined importance weight, an intelligent fusion system based on fuzzy integral theory was given, which can solve FEI-DEO and DEI-DEO fusion problems and realize the decision fusion. Simulation results were proved that fuzzy integral algorithm has enhanced the capability of handling the uncertain information and improved the intelligence degrees展开更多

The results indicate that: First, both the teachers and students attached much importance to language, but the teachers put significantly more emphasis on organization and content whereas the students put significantly more emphasis on vocabulary;Second, the beliefs of students were heavily influenced by their conceptions of the purposes of EFL writing tasks and the assessment criteria adopted to mark their writing;Third, the disparity between teachers' and students' beliefs caused them to emphasize different aspects of an essay when giving feedback;Finally, students' beliefs had a negative impact on the development of effective writing strategies. Pedagogical implications are suggested.展开更多
