Multi-level ant system - a new approach through the new pheromone update for ant colony optimization

A new urban logistics delivery system is brought forward to resolve the traffic congestion. With the development of economy, there are more and more vehicles in megapolises, so the burdens of city roads become more and more heavy, and the environmental impacts and energy shortage become severer. Underground Logistics System (ULS) is used to resolve the problem in many countries. For the high cost and limitations of special use, not all the megapolises can build ULS, and the effect of ULS is limited. In the paper, the new urban logistics delivery system is designed based on Rail Transit. The framework of rail transit based urban logistics delivery system is put forward. The system is composed of management information center, cargo center, rail transit and delivery workers. To support the system, general transport containers are conceptual designed. The management and control system is used to fulfill the effective operation management and control works. At the end, the paper discusses the criterion of nodes planning.I.

The use of new information and communication technology is increasingly common nowadays. Content adaptation of learner's profile is an issue that concerns many researchers in education field. Several studies have been conducted to achieve high quality learning and adapt the content to learners' profiles.Some researchers have properly applied the ant colony algorithm to the field of e-learning.In this work we are interested in the improvement of ant colony algorithm for scheduling units of courses (e.g., a Java course). We follow a pedagogical way to establish units. We define five concepts to maintain learners' motivation and adapt the algorithm behavior to our context. So our contribution is a new pheromone that influences the algorithm to choose the right unit in a pedagogical sequence. Many changes are taken into consideration to implement the new version of ant colony algorithm. The trainers apply weights to each arc that are linking two units of the course. The profile definition is a part that was preliminary defined in previous work using fuzzy logic method.Method Roulette Weel is applied for the selection part. This method is interested in finding the final state. It is used in addition to the ant colony algorithm for the path exploration and optimal learning path.
