[0047] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0048] In an exemplary embodiment, as Figure 1 and Figure 2 shown, a method for combining Diagram B and Diagram P for structural analysis and functional analysis is provided. This method is executed by a computer device, which can be specifically executed by a computer device such as a terminal or a server alone, or jointly executed by a terminal and a server. In the embodiments of the present application, this method includes the following S101 to S108. Among them:

[0049] S101, analyze the product structure using the Diagram B module, determine the external objects, and obtain the product structure tree;

[0054] S103, determine the input of the P diagram module by calling the product structure tree generated by the B diagram module;

[0055] S104, call the product characteristic library or add the expected output of the new P diagram module;

[0056] S105, call the noise factor library, part factor library, external objects of the B diagram module, interface factor library or add the noise factors of the new P diagram module;

[0060] S106, call the failure library or create the unexpected output of the new P diagram module;

[0061] S107, call the measure library or add the control factors of the new P diagram module; Adding control factors is equivalent to adding preventive / detection measures to the structure tree.

[0062] Adding control factors for noise factors is equivalent to the logic of adding preventive or detection measures for failure causes, including measures that can be modified to current or optimized measures.
