Embodiment Construction

[0062] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0063] Such as figure 1 Shown, the present invention discloses a kind of system comprehensive evaluation method based on colored Petri net, comprises the steps:

[0064] Step 1), input the corresponding four-character information of each component in the system, namely reliability, maintainability, testability and safety information, into the Petri net database, assign it to the token in the corresponding component storehouse, and set its color is black;

[0065] The Token includes value, time and attribute, wherein the value is the four-character parameter value of the component, the time is the stage value of the life cycle of the component, and the attribute is the security mark;

[0066] Step 2), the initial identification of whole Petri net is set;

[0067] Step 3), set the initial trigger place, give it the corresponding dynamic token, and...

Abstract

The invention discloses a system comprehensive assessment method based on a colored Petri network and aims to solve the mismatch of four characteristics during four-characteristic assessment of a complex system. The method includes: defining a new comprehensive assessment system, and building the four-characteristic integrated assessment model of the system; using the strong description capability of the colored Petri network to divide the four characteristics of the complex system into availability (reliability and maintainability), testability and safety, dyeing the token, representing the availability, in the Petri network into yellow, dyeing the token, representing the safety, in the Petri network into blue, and dyeing the token, representing the testability, in the Petri network into purple; completing the comprehensive assessment of the complex system by using the built four-characteristic integrated assessment model and the four-characteristic colored Petri network. The method is a circulation process of design and assessment. By the method, the current mismatch problem of the four characteristics is solved effectively.

Description

technical field [0001] The invention relates to the field of comprehensive evaluation methods for four-character integration in the development stage of complex systems, in particular to a system comprehensive evaluation method based on colored Petri nets. Background technique [0002] With the continuous advancement of science and technology, the continuous integration of various disciplines, especially in the fields of computer information, intelligent control and equipment manufacturing, has formed a large number of multi-functional complex systems. At the same time, with the emergence of a large number of complex systems, the comprehensive evaluation of the reliability, maintainability, testability and safety of complex systems also follows, that is, how to make the reliability, maintainability, testability and safety of the system If the comprehensive performance such as property is high, it is necessary to know the state of the four properties of the complex system at ...
