Abstract
Cluster analysis is a kind of scientific and effective method to study “things of one kind come together”. Whenever Human beings are during the process of recognizing the world, they need to make some similar things into one category, in order to discover the rules, and then to realize and reconstruct the world on purpose. Previously, people classified things mainly by virtue of experience, and did some qualitative analysis, but rarely made use of data to do the quantitative research. With the development of science and the popularization of computer, utilizing mathematical methods to solve classification problems become possible, cluster analysis, as an important branch of the multi-analysis, is developing rapidly. When the research on clustering analysis before were subjectively giving weight, this clustering effect is always not very good. Therefore, suggesting a new method of calculating the weight, using the coefficient of variation, and through the real examples to prove that this method is effective. Thus, applying the new method calculating of the weight to help company in the transport of choice parcels more accurate line, through the SPSS statistical software to do some cluster analysis, it can draw to the corresponding conclusions.
