Abstract

A Safety-Critical System is a System whose break-down may cause disastrous effects to the environment, damage the system, or cause loss of life. Sometimes loss or misuse of information can indirectly cause harmful impacts due to system failure. In this paper, we study the various components of a drone system and analyze the safety of this Safety-Critical System (SCS) by looking into the potential failure using Fault Tree Analysis (FTA). Drone system failure or crash has been specified and verified using the Temporal Logic of Actions (TLA+) tool. The TLA+ tool consists of mathematical notations to describe the system specification using discrete mathematical concepts or formal methods. We tried to build a TLA+ Specification and Verification for this drone system, parse it using the TLC model checker successfully, and observed the final number of states to justify the correctness of the specification.

无人机系统使用TLA+的正式规范和验证:一个案例研究

安全关键型系统是指一旦发生故障，可能对环境造成灾难性影响、损坏系统或造成人员伤亡的系统。有时，由于系统故障，信息的丢失或误用会间接造成有害的影响。在本文中，我们研究了无人机系统的各个组成部分，并通过使用故障树分析(FTA)研究潜在故障来分析该安全关键系统(SCS)的安全性。无人机系统故障或崩溃已指定和验证使用行动的时间逻辑(TLA+)工具。TLA+工具由使用离散数学概念或形式化方法来描述系统规范的数学符号组成。我们尝试为该无人机系统构建一个TLA+规范和验证，使用TLC模型检查器成功解析，并观察最终状态数来证明规范的正确性。
