outer ballistic measurement of the aircraft. The

measurement radar maintenance capability

assessment is carried out through the small sensor

device to realize the various kinds of data

information collection, and use the various reasoning

algorithms and intelligent models to monitor, predict

and manage the state of the system, evaluate the

system's own health status, and combine the various

available resources and the beam conditions to create

the best maintenance strategy. This paper studies the

operation of the space measuring radar maintenance,

establishes the quantitative model by means of the

system dynamics method, and reveals the feedback

mechanism between the factors between the factors

in the system, and then evaluates the maintenance

and maintenance ability, and provides the

Suggestions for the decision department.

2 CONCEPT INTRODUCTION

The method of studying dynamic systems is based

on structural function simulation method, which is

modeled by the microstructure of the system, and the

dynamic behavior of the system is simulated and

analyzed by the basic operation structure of the

tectonic system, which is suitable for the

closed-system system that the research behavior has

defined, the feedback cycle, balance and

consolidation of the main research system, and the

determination of the stock and flow of the system.

The space measurement radar maintenance

guarantee can be regarded as a complex system that

has a structural order, counterguard object and

maintenance change, and has a complex system that

has certain self-organizing ability in the maintenance

task, and the system dynamics method provides the

3 DOMINANCE ANALYSIS

System dynamics is a specific problem to solve, not

the whole system. The purpose of modeling is to

help determine the system boundary and variable

relationship, strengthen the understanding and study

of the internal feedback structure and dynamic

behavior relationship of the system. The use of

system dynamics to study the ability of radar

maintenance and maintenance of the space

measurement radar is characterized by the following

advantages:

1) the evaluation of radar maintenance and

maintenance is a kind of complex time-varying

system problem of nonlinear, high order, variable

quantity and multiple feedback, and its system itself

has not only clear, determined relationship, but also

a fuzzy and random factor (Rehak, 2006).The simple

qualitative analysis is floating on the surface, the

complete mathematical description and the accuracy

and the overall failure of the whole side is not

guaranteed and the defect, the combination of

qualitative analysis and quantitative research of the

system dynamics, and the simulation realizes the

interaction between the human-computer can be

convenient and effective.

2) the measurement radar maintenance and

maintenance ability assessment is difficult to

quantify, but the system dynamics model is a kind of

structural dependent model, which focuses on the

dynamic and behavior of the system's internal

structure, and the analysis of the data is not high,

which is suitable for the research of the maintenance

and maintenance ability of the space measurement

radar.

3) the system dynamics can be tested and tested

repeatedly by the space measurement radar

maintenance and maintenance ability assessment. In

this paper, the model is consistent with the actual

situation, and the parameters of the system are

controlled, the simulation experiment is carried out,

the dynamic behavior and the changing trend of the

system are observed, and the optimal system

structure and parameters can be designed, and the

optimal system function is obtained, and the

scientific development of the evaluation of the space

measurement radar maintenance and maintenance

ability is promoted.

4 MODEL BUILDING

The main variables of important relationship

between the selection and the space measurement

radar maintenance ability are evaluated as the typical

representative of the description system. The

relationship diagram of 7 flow levels is obtained by

qualitative analysis, as shown in figure 1. The main

variables are described as follows:

1) the growth of funds invested is influenced by

the original foundation, and the more emphasis is

attached to the construction of radar maintenance

and maintenance, the more money is invested

(Benigno, 2005). At the same time, the higher the

overall level of the space measurement radar

maintenance and safety capability, the lower the

urgency of construction, the smaller the investment.

2) the growth of talent is influenced by the

original foundation. Through personnel training

input, also can cultivate some information-based

talents. At the same time, a good talent policy

environment can also attract and retain a large

number of informationized talents.

3) information resources are related to the

original basis, while a large amount of information

resources development investment, good talent

support, higher technical means, and improved

information resource development environment have

important influence on the change of information

resources.

4) the improvement of technical means is related to

the original basis, and the higher the cost of

technology development and technology

procurement, the higher the technology, the higher

the talent index, the higher the degree of application

of information technology, the better the technical

environment, the better the policy environment, the

better the development and application of the

technology.

5) the growth of environmental support is

affected by the original level, and the higher the

maintenance and maintenance of personnel, the

higher the capacity and efficiency of the

environment. At the same time, the higher the

overall level of the space measurement radar

maintenance and maintenance capability, the

demand for environmental support will decline.

6) the infrastructure construction level of the

equipment management information system of the

infrastructure construction team, which has increased

with the investment of the equipment management

information construction fund, and has its own

depreciation (Nyhuis, 2005).

7) the overall level of the space measuring radar

maintenance and maintenance ability is the result of

the common role of information technology,

information technology application, information

resource development and utilization, construction

environment and infrastructure level.

5 INSTANCE VALIDATION

In order to verify the validity of the test model, this

paper analyzes the dynamic model of the system

dynamics model by using the vensim simulation

software, and the simulation platform is shown in

figure 2. Vensim is a visual modeling tool based on

the window interface, which provides the graphical

editing environment, which is the advantage of the

software to realize the concept of the research target

system and the visualization of the text, and the

simulation results show that the intuitive and

function equation programming is convenient.

Simulation simulation time is 12 months, the

simulation step is 1, the unit is the month. The

simulation experiment sets two situations: case 1, the

environmental support is sufficient, the simulation

results are shown in figure 2; The simulation results

are shown in figure 3.

From figure 2, the increase of environmental

support will lead to the increase of capital input, the

quantity of talents and the means of technology,

which will improve the overall level of the

maintenance and maintenance of the infrastructure

and the space measurement radar maintenance. After

introducing the impact of risk interference, the

overall horizontal growth rate of the space

measurement radar maintenance and maintenance

ability slows, and gradually becomes stable.

From figure 3, Reducing environmental support

will lead to a decline in the overall level of the space

measurement radar maintenance and maintenance

capability. The amount of money, talent, technical

means and information resources are decreased. In

terms of degree, the number of talents is the most

influential, and the next is the investment, the

smallest effect is the total information resource.

6 CONCLUSION

The system dynamics dilemma provides some

reference for the operation of quantitative

maintenance system. Through the analysis of the

simulation results of the space measurement radar

maintenance and maintenance ability, the system

dynamics is a feasible and effective method for

evaluating the ability of radar maintenance and

maintenance. The next step will be to analyze the

influence factors of the maintenance and

maintenance of space equipment more

comprehensively, and to further verify the rationality

and scientific nature of the method in practice.
