摘要

Microprocessors/computers now control many critical functions such as arming and functioning of fuzes. The Software Fault Tree (Soft Tree) begins like any Fault Tree, then continues through the software to the inputs and other electronics. The Soft Tree provides a means of analyzing the hardware/software interfaces and software, as well as, hardware and man/machines interfaces. The technique facilities the systematic search for safety critical decision points and nodal points in the software. The Soft Tree will also highlight areas where a single bit error can cause a hazardous condition. The Soft Tree is similiar to the Fault Tree in nature; therefore, engineers can use the technique now. Keywords: System supply; Weapon safety; Robotics.
