The Intelligent Scheduling Algorithm of Ivss § Phenomenon Descriptions 1. It is a multiple objective optimization problem and a 2. 3. NP problem that how vehicles are scheduled to make sure the route is reasonable and resources, costs and time are smallest. There are many scheduling algorithms for solving the vehicles scheduling, such as genetic algorithms, ant algorithms and so on. Because the act of vehicles movement is the same as ants looking for food, the ant algorithms are used to solve the problem in IVSS. It is the one of multiple methods. 10/30/2021 7

The Intelligent Scheduling Algorithm of Ivss § 1. 2. Ant Algorithms While walking from food sources to the nest and vice versa, ants deposit on the ground a substance called pheromone, forming in this way a optimal trail. The model of ant algorithms according to ant colonies foraging behavior. The Modeling of Scheduling Given there are N freights should be transported and M vehicles can be scheduled, and the N freights are divided into N steps with only one freight being done in the every. If it is hoped that the cost of the whole task is lowest, every step should be cheapest. In every step, ant algorithms are used to find an optimal path. 10/30/2021 8

Solution of a Dispatch Task § 1. 2. 3. 4. 10/30/2021 A scheduling task can be divided into 4 steps according to the study above in practice. The first step: the goods information are obtained. The second step: all vehicles data of around goods are searched and transferred in the surrounding area of goods. The third step: the best scheduling plan is calculated based on ant algorithms intelligent scheduling software. The last step: freights transportation are automatic tracked and recorded until the task is finished. Then, all equipments are prepared for the next round scheduling plan. 9

Conclusion § Two main parts: the mobile terminal and the § § § monitoring center are contained in VISS. Many technologies such as GPS, GPRS/CDMA, GIS, RS and Internet are used in VISS. Because ant algorithms are used in the system, a good effect is achieved in practical operation. The system not only can be used in the vehicles, but also in the vessel and other fields, and the solid technical support will be provided for the ITS research. 10/30/2021 10
