Description

System structure evaluation method and system based on design data and experimental data
Technical Field
The invention relates to the field of system structures, and particularly discloses a system structure evaluation method and a system based on design data and experimental data.
Background
An architecture is a guide to the structure of the various system components, the relationships between the components, and to their design and evolution. The blueprint for guiding the construction of the military information system provides a way for various stakeholders of the system to know and understand the existing system and provides whole-course guidance for the analysis, design, implementation and maintenance of the military information system. The architecture design is helpful for promoting the communication and understanding of various personnel, assisting the design decision of the support system, guiding the development and integration of the system and guiding the evolution of the system.
The system structure is in the early stage of system construction, and is the key for carding system design factors and measuring the quality of future system construction. The efficient evaluation of the system structure design result is beneficial to the system construction and evolution of the next step. However, currently, evaluation of architecture design results is often achieved by means of human judgment or subjective decision, and although in recent years, data-centric architecture design ideas are emphasized, designed architecture data is often used for static architecture analysis, which is not strong in persuasion. In addition, the current architecture design achievement is difficult to effectively guide practice and combine with experimental simulation, so that reasonable and effective architecture evaluation data is difficult to provide, and the architecture evaluation work is difficult to effectively expand. The system maturity can be used as a key index for measuring the structural design result of the system, and is judged by analyzing the capability index in the structural capability view of the system. If the effect is better when one system structure design scheme meets all the capability indexes, the system maturity of the scheme can be considered to be higher. At present, the calculation of the system maturity is based on the development of specific system construction results, such as the support of each weapon in a weapon equipment system to a combat system. And at present, an analysis technology is not developed for the system maturity at the system design stage of system planning.

The embodiment first proposes an architecture evaluation method based on design data and experimental data, and with reference to fig. 1, the method includes the following steps:
s1: architecture design data and experimental data are obtained.
The architectural design data includes the following steps. :
s101: and decomposing the architecture according to the capacity to obtain a capacity decomposition relation of the architecture.
The capability resolution relationship represents a resolution relationship between capabilities of the architecture, and referring to fig. 2, for example, the search and rescue capability can be divided into an assistance capability, a search capability, a command and control capability, and a rescue capability.
S102: setting capability effect indexes of each capability in the capability decomposition relationship and setting capability correlation activities of each capability in the capability decomposition relationship.
The capability effect index describes an index required to achieve each capability, is an expression of coarse granularity of capability measurement, and needs to be further analyzed and measured through other factors or attributes. For example, the rescue ability can be measured by a rescue success rate index, the search ability can be measured by a search success rate index, and the command control ability can be measured by commanding timeliness. The measurement standards of the capacity index need to be set in the system design process and are generally divided into 4 standard levels, for example, for the rescue success rate, the standard one is 40%, the standard 2 is 60%, the standard three is 80%, and the standard four is 100%, and these data are set by the user in the system structure design process and are key indexes for measuring the system maturity. The following table 1 is a capability effect index table.

The mapping relationship between the abilities and the activities represents the support relationship between the fighting activities and the abilities, can be a many-to-many relationship and is often described in a form of a table or a matrix, for example, the activities related to the rescue abilities comprise the activities of positioning victims, monitoring bodies, receiving rescue information, searching activities, turning to safe areas and the like. Table 2 below is a capability to activity mapping, i.e., a capability-associated activity.

S103: and setting relevant indexes of the capacity associated activities.
The activity effect attribute represents a relevant index of activity execution, is obtained by determining an effect attribute of each activity of the combat activity model, and is often described in a table form, for example, positioning the effect attribute of a victim to positioning the time of the victim, monitoring the effect attribute of a body to be the physical condition, and the like. Table 3 below is the activity effect attribute, i.e. the relevant index of the ability-related activity.

S112: the experimental level was determined for each experimental factor.
S113: and generating an experimental sample according to the experimental scheme and the experimental level.
The test scheme associated with each capability index corresponds to a number of test samples, each test sample being a combination of different levels of a plurality of test factors. For each test protocol, any corresponding test sample is selected as the capability index to be analyzed and evaluated. And obtaining a combination of the test samples of the plurality of test schemes, namely the design scheme of the system structure under the scene. The two steps are the derivation of the test scheme execution result based on the architecture design data, and are the analysis and evaluation of the architecture simulation test result.
S114: and obtaining an experimental structure according to the experimental sample as the system structure experimental data.
For selected combinations of test samples, test results for each sample may be obtained. And comparing the test result with the measurement standard of the capability index in the system structure data to obtain the actual grade value of each capability index, and using the actual grade value as the bottom input for measuring the system maturity. The step is the key content of the invention, and the measurement result of the capability index is obtained by comparing the system structure design data with the system test data and is used as the basis of the system analysis, thereby realizing the system analysis technology based on the test and distinguishing the qualitative and static analysis of the system effect attribute from the traditional method. The step uses the system structure design data as the analysis basis again, which shows that the system structure design data can effectively support the practice.
The experimental scheme referred to in this embodiment is a scheme set for measuring each capability index, for example, for the rescue success rate in table 2, an experimental scheme is set, the activity attribute corresponding to the rescue capability is used as an experimental factor, and the rescue success rate under each experimental level combination is analyzed by determining different experimental level setting experimental schemes. The experimental plan setup process is described below, and the results of obtaining the performance indicators can be output as an input to the system maturity measure of the present invention through the execution of the experimental plan.
In the experimental scheme setting process, each capability index is used as an experimental scheme, then an activity attribute set associated with each capability index is determined according to the mapping relation between the capability and the activity, the activity attributes are used as experimental factors of the capability index, and other activity attributes are used as uncontrollable variables to be assigned in the experimental process. As shown in table 4, each ability index is used as an experimental plan, and the activity attribute corresponding to the ability index is used as an experimental factor to form the experimental plan.

Figure BDA0002701611540000061
Based on the determined experimental protocol and the level values of the experimental factors, experimental samples may then be generated according to different experimental sample generation methods, as shown in table 6. For example, for the experimental plan 1, 9 experimental samples are generated in an orthogonal design, and these experimental samples are used as input of the experiment, and the determination of the capability index value is performed through the experiment.

And the construction of the capability index system is convenient for converging and calculating the maturity of the system from bottom to top. The first two steps are the export of the data of the architecture design, and the idea that the architecture design takes the data as the center is embodied.
