Abstract

Software processes are enacted instances of process models. Process models are themselves instances of process meta-models that provide the various abstractions in terms of which process models can be described. This paper introduces a unified framework for software process modeling, enactment and evolution. The approach supports the customization/evolution of a process model and of its underlying meta-model. The process model and its meta-model are both described as specializations of kernel object classes using an object-oriented definition toolkit. Classes at one level become object instances at the upper level. The customization/evolution of models and meta-models is supported in a uniform way by creation/modification of kernel objects and by specialization of their classes. The overall approach is illustrated through a number of simple examples. Our definition toolkit has been written in Standard ML. This choice allows a precise semantics to be assigned to the various constructs using denotational semantics description techniques; at the same time executable prototypes of process-driven environments are produced from such descriptions.<>

流程模型定制、制定和演化的反思方法

软件过程是过程模型的实例。流程模型本身就是流程元模型的实例，元模型提供了各种抽象，可以根据这些抽象来描述流程模型。本文介绍了一个统一的软件过程建模、制定和演化框架。该方法支持流程模型及其底层元模型的定制/演进。进程模型及其元模型都被描述为使用面向对象定义工具包的内核对象类的专门化。一层的类成为上层的对象实例。通过创建/修改内核对象及其类的专门化，以统一的方式支持模型和元模型的定制/演进。通过一些简单的示例说明了整个方法。我们的定义工具包是用标准ML编写的。这种选择允许使用指称语义描述技术将精确的语义分配给各种结构;同时，过程驱动环境的可执行原型是由这样的描述产生的。
