Problems solved by technology

However, most of the studies on human-machine systems simply treat human beings as a repairable hardware device, and do not fully consider human cognitive characteristics.

Embodiment Construction

[0050] The present invention is based on a multi-stage man-machine system reliability modeling analysis method, see Figure 5 As shown, its specific implementation is as follows:

[0051] Step 1: Propose Modeling Analysis Hypotheses Hypotheses

[0052] Step 1): Hypotheses for the impact of human-computer interaction:

[0053] Due to the particularity and complexity of human beings, it is impossible to truly consider human beings in all aspects. Therefore, in order to simplify the analysis process and improve the efficiency of the analysis process, certain assumptions need to be made on the impact of human-computer interaction

[0054] 1) People are irresponsible persons, and only equipment failures can induce human error;

[0055] 2) Multiple devices will not fail at the same time, and no other devices will fail during the process of human response to a fault;

[0056] 3) Equipment failure obeys exponential distribution;

[0057] 4) Equipment failure during the task cannot...

Abstract

The invention provides a reliability modeling analysis method based on a multi-stage man-machine system. The method comprises steps: 1, proposing a modeling analysis assumption; 2, describing the multi-stage characteristics of the man-machine system; 3, drawing a multi-stage man-machine system fault tree; 4, drawing a single-stage BDD diagram, namely a binary decision diagram; 5, drawing a BDD diagram of a multi-stage man-machine system; 6, calculating the probability values of each state of the multi-stage man-machine system. Through the implementation of the above steps, the problem that human phase characteristics are not taken into account in the reliability modeling and analysis of multi-stage man-machine interaction system is solved, and the dynamic interactive analysis effect whichbetter reflects the reliability of multi-stage man-machine interaction system is achieved.

Description

Technical field: [0001] The present invention provides a reliability modeling and analysis method based on a multi-stage man-machine system. The reliability modeling analysis of computer systems is more in line with the actual situation, and belongs to the cross-technical field of reliability design and human factors engineering. Background technique: [0002] A multi-stage system is composed of several distinct stages, each with different performance and reliability. Since the early reliability analysis of multi-stage systems was mainly based on simulation methods, the processing method was mainly numerical methods, and no human subjective active factors were added. Because of the intra-stage and cross-stage characteristics of equipment, and human behavior will affect the reliability of equipment and be affected by equipment reliability, it is particularly necessary to analyze the human factor in multi-stage systems. [0003] There are few studies on the reliability of hu...
