Parking Reservation System Based On Java

Nowadays, parking is becoming a global problem. In this case, parking guidance system arises at the historic moment. Many countries have conducted in-depth research and practice on the parking guidance system, and achieved good results. However, there are still some deficiencies in the existing parking guidance system: 1. Parking guidance system can only provide owners with effective parking number before owners enter the parking lots, and can't provide specific location. 2. Parking guidance system has no reservation function. This article aimed at the deficiency of the existing parking guidance system, added reservation function on the basis of the original, and can guide owners to reach the target parking spaces quickly and easily.First of all, this article patterned after a company's underground parking layout to build a small parking lots model. Collecting factors which owners consider in choosing parking space, and making use of grey entropy to get the best parking space. In addition, owners can make a unilateral decision by their own needs. Secondly, to find an optimal path for owners. At present, there are many kinds of algorithms to obtain the shortest path. This article mainly introduces three kinds of algorithms-- Dijkstra algorithm, Floyd algorithm, ant colony algorithm. By analyzing the working principle of these three algorithms, and using MATLAB software to simulate, finally get the best path and the shortest distance. Analyze the advantages and disadvantages of the three algorithms, select the appropriate model for their own algorithm. Finally, with the software to achieve a parking reservation system. The system is based on Java language, and combined with Oracle database operation. Using MVC framework to realize the separation of the page, data, logic code. Combining Html, JS, CSS to display user login interface and interface which user select a parking space.In the article, compared with the original system, the design of the parking space reservation system is more perfect and intelligent. In addition, the design of the parking space reservation system can not only solve the problem of parking effectively, but also enhance the user experience.
