系统和软件工程.高级Petri网.第3部分:扩展和结构机制

[中文适用范围]： 本文件规定了 Petri 网的扩展、增强和结构化机制，应用于 ISO/IEC 15909-1 提出的定义。本文件促进了新型 Petri 网及其互操作性的定义，同时与 ISO/IEC 15909-1 中定义的兼容。本文件针对新变种 Petri 网的设计者进行了编写，通过定义通用扩展、增强和结构化机制以及一个通用的定义过程来实现。本文件适用于各种并发离散事件系统，特别是分布式系统。其典型应用领域包括：——需求分析；——规范、设计和测试套件的开发；——改造之前的现有系统的描述；——建模商业和软件流程；——为并行语言提供语义；——增强对系统的信心的仿真；——正式分析系统的行为；——以及开发 Petri 网支持工具。本文件可应用于各种系统和流程的设计，包括航空航天、空中交通控制、航空电子设备、银行、生物和化学过程、商业流程、通信协议、计算机硬件架构、控制系统、数据库、国防指挥与控制系统、分布式计算、电子商务、容错系统、游戏、医院程序、信息系统、互联网协议和应用程序、法律流程、物流、制造系统、代谢过程、音乐、核能系统、操作系统、运输系统（包括铁路控制）、安全系统、电信和工作流。 [外文原描述]： This document defines enrichments, extensions and structuring mechanisms of Petri nets, applied on the definitions proposed in ISO/IEC 15909-1. This document facilitates the definitions of new kinds of Petri nets and their interoperability, while remaining compatible with those defined in ISO/IEC 15909-1. This document is written as a reference for designers of new Petri net variants, by defining common enrichments, extensions and structuring mechanisms, as well as a generalized process for defining new ones. This document is applicable to a wide variety of concurrent discrete event systems and in particular distributed systems. Generic fields of application include: — requirements analysis; — development of specifications, designs and test suites; — descriptions of existing systems prior to re-engineering; — modelling business and software processes; — providing the semantics for concurrent languages; — simulation of systems to increase confidence; — formal analysis of the behaviour of systems; — and development of Petri net support tools. This document can be applied to the design of a broad range of systems and processes, including aerospace, air traffic control, avionics, banking, biological and chemical processes, business processes, communication protocols, computer hardware architectures, control systems, databases, defence command and control systems, distributed computing, electronic commerce, fault-tolerant systems, games, hospital procedures, information systems, Internet protocols and applications, legal processes, logistics, manufacturing systems, metabolic processes, music, nuclear power systems, operating systems, transport systems (including railway control), security systems, telecommunications and workflow.
