A PC-based real-time quality control (QC) system for multitest analyzers has been developed as a prototype. The system is built with use of a relational database management system (DBMS). Control values from the various analytical channels are stored and administrated with use of the DBMS. The control values collected during various stages of control are filtered through statistical control procedures and the control status of the instrument is continuously presented in color-coded fields indicating the possible presence of critically sized systematic or random analytical errors. The knowledge about rational trouble-shooting of a specific instrument is represented in a network structure and stored in relational tables of the DBMS. An inference engine performs alternating backward and forward reasoning in the network and guides the operator in trouble-shooting.
已开发出一个基于个人计算机的多测试分析仪实时质量控制（QC）系统原型。该系统使用关系数据库管理系统（DBMS）构建。来自各个分析通道的控制值通过DBMS进行存储和管理。在控制的各个阶段收集的控制值通过统计控制程序进行过滤，仪器的控制状态以颜色编码字段持续呈现，指示可能存在的临界大小的系统或随机分析误差。关于特定仪器合理故障排除的知识以网络结构表示并存储在DBMS的关系表中。推理引擎在网络中进行交替的正向和反向推理，并指导操作员进行故障排除。
