City logistics turns into a foundation and supporting system of city economic development. The ability of city logistics becomes an importation section of city competition capability. In this paper, a dynamic evaluation of city logistics capability is discussed. An index system of city logistics is built which includes basis, support and promotion. A dynamic projection pursuit evaluation model is also developed. Furthermore projection pursuit technology truly makes the synthetic evaluation result more discrete. A panel data set of 12 cities of the Changjiang River delta is used in empirical studies. Demonstration results indicate that the city logistics capabilities of Shanghai, Nanjing, Ningbo and Hangzhou are much higher than other cities and they have stronger logistical capabilities.

The Shiplock Service Level is a comprehensive index to evaluate the shortcut, comfort, convenience and safety et al of ships waiting to pass the shiplocks. Based on the characters of the shiplock operation, an index system which can reflect the condition of the shiplock operation is proposed. Then the comprehensive evaluation model is built in two core steps: The first step is to use Main Factor Analysis to screen out the important indexes to evaluate the Shiplock Service Level based on the basic information of shiplocks located on the North Jiangsu Canal of China; and the second step is to use AHP to propose the Comprehensive Evaluation Model of Shiplock Service Level based on the important evaluation indexes mentioned above. According to the characters of the shiplock operation, the determination way of the indexes' weights and the nondimensional way for the indexes are presented. Finally, the comprehensive evaluation model is used to evaluate the service level of typical shiplocks on the North Jiangsu Canal of China.

It is an intensive way for solving the problems of crowded shiplock to strengthen its management and efficiency of Running & Scheduling. According to the present situation, we study the optimization model on the "unpredictable/single line" condition. The conception of `Maximum Waiting Time' to the waiting ships for shiplock is proposed based on the psychological theory. On the basis of the three traditional service ways, a new service way called time limit service way is proposed. Aiming at the maximum utilization of a chamber, an optimized dynamic model of ship combination in chamber is developed using the 0–1 programming while queuing the ships according to their respective types which are extremely large, large, medium, and small. And this model is put into practice in Lvsi Shiplock and the result shows that Running & Scheduling efficiency can be promoted by using this optimization model.
