Timetable of the airport coach is designed based on the relationship between the headway and the passenger volume. Firstly, the timetable is proved to be the important factor influencing the passenger volume and the operating cost. Secondly, referring to the theory of the firm equilibrium, the relationship between the timetable and the passenger volume is discussed. Thirdly, based on the theoretic analysis, the optimization model of an irregular timetable with changed demands is built, and the aim of this model is to maximize the profit of the airport coach system. Finally, the optimized timetable and the being needed coach vehicles are calculated by solving the model with matrix code genetic algorithm. [ABSTRACT FROM AUTHOR]

Researching is about evaluation and sort of the direction that targets are most likely to attack along before deploying air defence fire units around key point. In this paper, firstly, air attacking weapons attacking direction evaluation index system and quantitative rules are provided depend on the modern air attack character. Using grey clustering theory to divide the likely attack direction into different classes and sort them according to the similar coefficients. Then we rank the different likely directions in order of evaluation scores using non-uniform grey relational method based on AHP and DEA. The simulation results proved that this method can solve this problem. [ABSTRACT FROM AUTHOR]
