Abstract

The construction of China Railway Express (CRE) distribution centres plays an important role in improving the operational efficiency of CRE and promoting the development of regional economy. However, it is difficult to quantify the relevance of distribution centres because there are fewer studies on the cargo sources radiation range. This paper is intended to determine the radiation range of the cargo sources and provide a quantitative approach for CRE distribution centres’ planning. First, a comprehensive strength evaluation indicator system was constructed based on the urban economic development, transportation capacity and the operational status of CRE. Then, an AHP-Entropy method was used to determine the weight of each indicator and obtain the comprehensive strength of the city. According to the obtained comprehensive strength and the characteristics of the city’s cargo distribution, an urban thermal radiation model was constructed to calculate the cargo sources radiation range integrated with field strength theory. Finally, the break-point model was utilized to verify the proposed model. The results showed that the calculations were consistent with actual case, and results obtained by using the thermal radiation model in Urumqi were more reliable.
