Introduction
This part of GB/T 38852 discusses the methods that should be used when evaluating the system characteristics of BCS.
System evaluation refers to the judgment that the system is suitable for a specific mission or a type of mission based on evidence.
In order to obtain all the evidence, a complete assessment of all system characteristics related to a specific mission or a
Factor).
Since it is difficult to achieve a complete evaluation of all system characteristics, the principles behind the system evaluation are.
---Identification of the importance of each relevant system characteristic;
---Relevant system characteristics evaluation plan, which should show good cost-effectiveness in the evaluation of multiple system characteristics.
In the implementation of system evaluation, the key is to obtain the greatest increase in the credibility of the applicability of the system under the actual cost and time constraints.
Evaluation can only be carried out when a mission has been declared (or given) or any mission has been assumed. When there is no mission, no evaluation is made. but
Yes, the system can be checked to collect and organize data for future evaluations. In these cases, since the assessment is the assessed group
Into a part, this part can be used as a guide for the evaluation plan and provide methods for performing the evaluation.
When preparing for the assessment, you will find that the definition of the system is too narrow. For example, a control system with two or more versions of shared resources
Facilities (such as networks) should consider version coexistence and interoperability. In this case, the system being evaluated should not be limited to "new"
BCS, but should include these two versions. In other words, the boundary of the system should be changed to include all systems to solve these problems.
The structure of this part and the relationship with other parts expected in GB/T 38852 are shown in Figure 1.

Part 2.Evaluation Methodology
1 Scope
This part of GB/T 38852 gives the evaluation method of the basic control system (BCS) based on the basic concept of GB/T 38852.1
Jurisprudence.
This section describes various methods for analyzing and measuring the relative importance of various system characteristics and influencing conditions, as well as determining evaluation procedures.

4 Evaluation method
Due to the complexity of BCS, a comprehensive and comprehensive evaluation of BCS is bound to invest a lot of manpower and time, which is neither practical nor practical.
economic. Therefore, it is very important to carefully analyze and specify the purpose of the evaluation before planning the evaluation process.
The mission or mission type of the system is broken down into tasks.
The tasks performed by the system should be determined based on the selected BCS and its characteristics, as well as the required functions. In this way, the system
System functions required to achieve its mission.
The mission of the system usually requires several system features that are not directly related to the system task, including documentation and support services.
The evaluation procedure should be formulated in advance, and the evaluation purpose, system requirements and system specifications should be clearly defined.
Note. In some cases, such as applications subject to regulations, an independent evaluator may be required to design and perform the evaluation.
If the mission is uncertain, it cannot be evaluated. Of course, it is possible to review the system to collect and organize data for subsequent evaluations.
