Modern medical systems undertaking the task of surveillance of patients are safety-critical systems steered by software. Such systems will bring man's life into hazard if they fail to meet patients' requirements; so, adequate reliability of the algorithms and computations used by software of such systems is a matter of concern. The environment of a medical safety-critical system consisting of a patient has safety requirements that should be satisfied by the system. A safety requirement is the one that if it is violated, the system environment will be subject to severe risk. An effective method to verify the algorithms and computations used by software of such systems against safety requirements is to keep the software under surveillance at run-time. This paper aims to present a model-based method to construct a run-time monitor for a safety-critical medical system called Continuous Infusion Insulin Pump (CIIP).
现代医疗系统承担着监测患者的任务,这些系统是由软件驱动的安全关键系统。如果这些系统不能满足患者的需求,它们将给人类的生命带来危险;因此,此类系统软件中使用的算法和计算的充分可靠性是一个值得关注的问题。由患者组成的医疗安全关键系统的环境具有安全性要求,系统应满足这些要求。安全性要求是指如果违反了该要求,系统环境将面临严重风险。一种有效的方法是在运行时对这类系统软件使用的算法和计算进行监控,以验证其是否符合安全性要求。本文旨在提出一种基于模型的方法,为一种名为连续输注胰岛素泵(CIIP)的安全关键医疗系统构建一个运行时监视器。
