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 evaluation method based on colored Petri nets. When evaluating the four properties of a complex system, there are still "two skins" between the four properties. First, a new comprehensive evaluation system is defined and established. The four-character integrated comprehensive evaluation model of the system, secondly, using the powerful description ability of colored Petri nets, the four-character state of the complex system is divided into three categories: usability (reliability, maintainability), testability and security, and at the same time Color these three types of states, define the Token representing usability in Petri net as yellow; define the Token representing security as blue; define the Token representing testability as purple. The comprehensive evaluation model and the four-character colored Petri net are used to complete the comprehensive evaluation work of the complex system, and the present invention is a cyclic process of design and evaluation. The system comprehensive evaluation method based on the colored Petri net proposed by the invention effectively solves the current "separation" problem of the four characteristics.

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 ...
