Abstract

ECSAM is a requirements engineering and modeling method for computer-based systems (CBS). It is practiced and enhanced since 1980 by large numbers of systems and software engineers. ECSAM was developed in part at Israel Aircraft Industries for the analysis and design of complex reactive embedded systems and software. ECSAM guides the developers in systematic analysis and modeling of systems being developed and describing those using three consistent views; its conceptual architecture, operating modes, and system's capabilities. Each capability is further analyzed and described as a dynamic process. Using ECSAM it is possible to generate systematically the system's use cases and the resulting operational scenarios. The modeling technique is applicable in the analysis of systems and any level of subsystems. The method guides the developer in the derivation of the system requirements and their systematic allocation to and association with the model's elements at the respective levels. ECSAM was the prime motive for the development of the Statecharts technology developed by Prof. David Harel as part of the method. The paper provides an overview of the ECSAM method.

使用ECSAM的系统建模和需求规范:一种基于嵌入式计算机的系统分析方法

ECSAM是一种基于计算机的系统(CBS)的需求工程和建模方法。自1980年以来，它被大量的系统和软件工程师实践和增强。ECSAM部分由以色列飞机工业公司开发，用于分析和设计复杂的反应嵌入式系统和软件。ECSAM指导开发人员对正在开发的系统进行系统分析和建模，并使用三个一致的视图来描述这些系统;它的概念架构、操作模式和系统功能。每个功能被进一步分析并描述为一个动态过程。使用ECSAM可以系统地生成系统的用例和由此产生的操作场景。该建模技术适用于系统和各级子系统的分析。该方法指导开发人员推导系统需求，并在各自的层次上对模型的元素进行系统的分配和关联。ECSAM是开发Statecharts技术的主要动机，David Harel教授开发了Statecharts技术作为该方法的一部分。本文对ECSAM方法进行了概述。
