| Abstract: | Constructs an index to capture the logistics operation characteristics. Four indicators are gained using the time-asynchronization correlation analysis and the K-L information quantum analysis. Proposes methods to construct a composite logistics operation index and a principal-component logistics operation index based on the indicators. Calculates these two indices of China and makes comparative analysis. The results show that the principal-component logistics operation index could represent the logistics operation characteristics better. |
