中文摘要：

自动拍卖的基本思想是用某种代理机制——Agent代替人监控整个拍卖过程。提出分阶段第二价格封标拍卖模式，设计了多Agent网上自动拍卖协议，和多Agent拍卖系统体系结构。提出三种拍卖策略模型：平稳加价型策略、跳跃型策略和保密型策略。利用移动Agent开发平台Aglet实现了一个模拟系统，并进行了多次仿真模拟实验，对实验数据进行了详细分析。实验结果表明该模拟系统基本达到设计目的，并为进一步研究自动拍卖相关策略、协议提供了一个实验平台。

英文摘要：

Automated auction＇s idea is using an agent mechanism to help people controlling the process of auction. According to the fundamental theory of staged second - price sealed - bid auction, this paper designed an automated auction protocol based on multi -agent theory, and the architecture of auction system based on mobile agent technology, brought forward three kinds of auction strategy model. Then, mobile agent development platform - aglet was used to develop a simulation automated auction system, which could simulate the process and the strategies of on - line auction. Finally, results of the simulation were analyzed in detail. The success of the simulation system testified the feasibility of automated auction on - line, and provided a simulation platform for further research in strategies and protocol related to automated auction.
