Reliability Modeling and Analysis of Teleoperation System with Path-Dependence Effect Considered

In the teleoperation task of robotic arm system, path-dependent effects have significant impact on human–computer interaction failures. By analyzing the task process, this paper identifies the key factors affecting the success of the robotic arm teleoperation task and constructs a dynamic Bayesian network (DBN) model. On this basis, the path dependence which can promote or inhibit the human error is analyzed to revise the model. The revised model can clearly describe the path-dependent effect of human–computer interaction failures and also help to calculate the reliability of the complex system accurately.
