System safety assessment for IMA architectures using formal methods

Marinvent Corporation（Marinvent）是一家加拿大航空电子公司，专门从事飞行测试服务，系统工程，人因工程，软件开发和民用认证。目前，几家航空电子公司咨询Marinvent开发国际认证的集成模块化航空电子（IMA）架构，该架构提供高度集成的计算机硬件和软件系统，共享多个资源，如计算平台，输入输出模块和电源模块。然而，IMA组件在集成到飞机IMA系统之前需要技术标准订单（TSO）认证。TSO认证IMA组件在给定环境中的安全性，该组件将独立于任何特定飞机运行。到

Marinvent Corporation (Marinvent) is a Canadian avionics company that specializes in Flight Test Services, Systems Engineering, Human Factors Engineering, and Software Development and Civil Certification. Currently, several avionics companies consult Marinvent for developing internationally certified Integrated Modular Avionics (IMA) architectures, which provide a highly integrated system of computer hardware and software that share several resources, such as computing platforms, input-output modules, and power supply modules. IMA components, however, require a Technical Standard Order (TSO) certification before they are integrated within an aircraft IMA system. A TSO certifies an IMA component within a given environment where the component will operate to certain level of safety independently from any particular aircraft. To
