Abstract

Several formal approaches for the development of programs have been suggested including the transformational approach which allows to express formal developments as a linear equational proof. These developments lead to produce on the one hand the suited program satisfying its formal initial specifications and, on the other hand, the proof of correctness of this development. In most of the cases, this correctness is concerned with only functional aspects. Operational aspects are taken into account intuitively. This paper deals with nonfunctional correction of software. We suggest a transformational approach which allows the developer to produce cost expressions that can be interpreted in order to evaluate and get the benefit yielded by a given transformation application. These cost expressions are correctly associated to the intermediate objects of the development (abstract programs). We present a classification of the properties which are studied during the development phase and the correct formal transformational process allowing to get a particular evaluator for each kind of nonfunctional properties. Applications are given as well.<>

在正式开发过程中预测抽象程序的操作行为

已经提出了几种开发程序的形式化方法，包括允许将形式化开发表示为线性方程证明的转换方法。这些发展导致一方面产生适合的程序，满足其正式的初始规范，另一方面，证明了这种发展的正确性。在大多数情况下，这种正确性只与功能方面有关。直观地考虑操作方面。本文讨论了软件的非功能性校正问题。我们建议一种转换方法，它允许开发人员生成可以解释的成本表达式，以便评估并获得给定转换应用程序产生的收益。这些成本表达式正确地与开发的中间对象(抽象程序)相关联。我们提出了在开发阶段所研究的性质的分类和正确的形式转换过程，允许为每种非功能性质获得特定的评估器。申请表也有。
