ISO/IEC 16500的这一部分首先描述了最高级别的抽象系统参考模型（ASRM） 然后创建此抽象模型的特定实例，以定义DAVIC系统参考模型（DSRM）。 ASRM和DSRM并不表示DAVIC系统的首选实现方式；但是你要 作为指导DAVIC规范定义的工具。此外，如DAVIC规范所示 发布后，参考模型可用于帮助DAVIC的开发和实施- 顺从的 系统和产品。

This part of ISO/IEC 16500 describes an Abstract System Reference Model (ASRM) at the highest level first and then creates a specific instance of this abstract model to define the DAVIC System Reference Model (DSRM). The ASRM and DSRM are not intended to indicate preferred implementations of the DAVIC System; but are to be used as a tool to guide the definition of DAVIC specifications. Additionally, as DAVIC specifications are issued, the reference models can be used to aid the development and implementation of DAVIC-compliant systems and products.
