Agent-oriented modelling

计算机信息系统在今天的日常生活中无处不在——在家里，在工作中，在娱乐中。不久以前，系统通常是由单个开发组织根据一致的远景设计和构建的，用于单个用户组织的边界内。在当今开放的网络化世界中，信息系统依赖于网络上的众多其他系统和服务才能正常有效地运行。今天的系统跨越了许多边界——例如，支持业务交易、管理医疗保健、增强学习或玩游戏。它们需要许多软件系统和信息服务的合作，这些软件系统和信息服务是由其他软件开发人员创建的，由不同的服务提供者操作，并由具有不同兴趣和组织关系的人使用。因此，使用社会范式而不是过去的机械范式，可以更好地理解和分析今天的系统。社会范式能够更好地处理当前的问题，例如隐私、安全和信任、快速业务模型转换以及向面向服务的迁移。

Computer information systems pervade everyday life today - at home, at work, and at play. Not so long ago, a system is typically designed and constructed with a coherent vision by a single development organization, for use within the boundaries of single user organization. In today's open networked world, information systems rely on numerous other systems and services on the network to function properly and effectively. Today's systems cross many boundaries - e.g., to support business transactions, to manage healthcare, to enhance learning, or to play games. They require the cooperation of many software systems and information services created by other software developers, operated by different service providers, and used by people with different interests and organizational affiliations. Systems today are therefore better understood and analyzed using a social paradigm rather than the mechanistic paradigm of the past. A social paradigm is better able to deal with current issues such as privacy, security and trust, rapid business model transformations, and the move to service orientation.
