| 摘 要： | 本文根据系统论提出了开放对象的概念,认为客观世界是由开放对象构成的。它本身是一个递归定义的层次结构,同时具有目的性和适应环境、改造环境的能力即具有自我进化的能力。每个开放对象与其外界的通讯只能通过信息来完成,而且允许它们对同一个消息具有完全不同的理解。开放对象实质是面向对象+人工智能+数据库的一个模型。同时本文还给出它的形式定义。

| Abstract: | In order to simulate the real world more precisely and reduce the complexity of producing software, this paper proposes the concept of open object based on system theory, which regards the world as hierachical system and is capable of evolving on its own, since the traditional models cann't model the real world naturally and efficiently in some special application fields. Every open object communicates with another only by messages, moreover, for the same message, it is allowed to give the different comprehensions. Intrinsically, the open object is a model based on open object + artificial intelligence -f-database. Furthermore, a formal definition of open object is proposed. |
