## Abstract

This article proposes improvements to the placement, organizational structure, and adaptability of the evaluation model and proposes a comprehensive evaluation model for the multiattribute scheme of the particle swarm optimization algorithm. The structure table of the multimedia building design plan evaluation index, the plan evaluation table, and the standardized model of the plan evaluation value of the common method was proposed. It also proposes the import of “with tutor” type data of particle swarm optimization algorithm as well as the self-organizing neural network evaluation model and calculation method of “no tutor” type resource import. According to the complexity of architectural design evaluation and the nonlinear relationship between related influencing factors, we have studied the principles and methods of applying system analysis, designed comprehensive evaluation models, and comprehensively evaluated architectural design schemes.

## 1. Introduction

There are many types of buildings in multimedia, various functions, and big differences. These characteristics will be more prominent in subsequent development. When the multimedia collaborative architectural design plan is being evaluated [1, 2], we have learned about the modern architectural culture of our country. This series of problem solving is the key to how to carry out the evaluation of the multimedia collaborative architectural design scheme [3, 4]. Expert review and qualitative evaluation are dominant in the current program evaluation method, and the Delphi method and analytic hierarchy process are used to clarify the evaluation index weight method, and the effect is obvious [5, 6]. Of course, there are shortcomings, which will lead to subjective errors in the evaluation results. This error is unavoidable and will gradually increase with the rating level [7, 8]. Therefore, the use of fuzzy upper and lower level functions to evaluate the feasibility of the plan requires further research [9, 10]. Based on the difference of architectural design evaluation and the nonlinear relationship of corresponding elements, the theory and method of system analysis are proposed, a comprehensive evaluation model is established, and the architectural design plan is comprehensively evaluated. In recent years, in the application of the situation, researchers have also proposed a nonlinear comprehensive model that quickly digests the knowledge and experience of experts [11, 12].The theory of particle swarm optimization calculation method is easier to implement and has the characteristics of optimization. This is the reason why it can develop rapidly in a short period of time. It has been used in many areas, such as optimizing power systems, solving TSP problems, neural network training, traffic accident work, parameter identification, and model optimization. This paper explored the characteristics of swarm intelligence, the model characteristics of collaborative design system, and the application of particle swarm optimization calculation method in architectural design.

### 2.1. Determination of Indicator Weight

#### 2.1.1. Construct a Judgment Matrix

The three-dimensional visualization of the real scene of a building, generally speaking, must maintain the structure of the house and transfer the building from the old site to the new site based on the premise of a complete appearance, including longitudinal, lateral displacement, and rotation. The technical concept basis of the overall transfer is the independent individual based on the building. Behind the heightened building, it is necessary to overcome the friction of movement and the integrity of overcoming the interference of shaking. Real-life 3D visualization is simply called translation, and as the name suggests, it moves while maintaining a level at home. The main steps of the 3D visualization of the real scene of the building can be incorporated into the separation and displacement from the original position [13–15]. The general process is to cut off the building from the previous foundation and transfer it to the commission structure, install a mobile device under the transaction structure to form a movable whole to move the building to a predetermined location, and request the location to connect the AHP method and the evaluator about each evaluation The relative importance of elements is judged. These judgments are expressed as judgment matrices with numerical values. The specific form of constructing the decision matrix is as follows through the comparison and evaluation elements such as the brain raid method and the expert survey method.(1)B=b11b12⋯b1nb21b22⋯b2n⋮⋮⋱⋮bn1bn2⋯bnm.In the formula,bij is the relative importance of Bi to Bj for Ak.The text uses a ratio of 19 to evaluate the significance of the numerical value representing the meaning: 1 shows the same importance compared with the two elements. 3 represents the comparison of two elements. 5 represents the comparison of two elements. Obviously, 7 represents two elements. More important than being strong. 9 means two elements. TheBi number between them is 2, 4, 6, and 8, and Bj represents the intermediate value of the abovementioned adjacent judgment.In the formula,bij is the relative importance of Bi to Bj for Ak.The text uses a ratio of 19 to evaluate the significance of the numerical value representing the meaning: 1 means that it has the same importance compared with two elements. 3 represents the comparison of two elements. 5 represents the comparison of two elements.Bi is obviously more important than Bj; 7 means that compared to two elements, Bi is more important than strong Bj; 9 means that compared to two elements, the number of Bi between them is 2, 4, 6, and 8, which means the abovementioned adjacent judgment median.


#### 2.1.2. Calculate the Weight of Each Indicator

The calculation of index weights can be attributed to the calculation of eigenvectors and eigenroots of the determination matrix. That is, for the judgment matrix B, calculate the eigenvalues and eigenvectors that satisfyBW=λmaxW, where λmax is the largest feature root of B and W is the normalized feature vector corresponding to λmax. The component Wi of W is the weight corresponding to each index. In this paper, the square root method is used to calculate the characteristic root. The specific steps are as follows: (1)
Calculate the productMi of each row of the judgment matrix B: (2)Mi=∏j=1nbiji=1,2,⋯,n.(2)
Calculate thenth root of Mi to W¯i: (3)W¯i=Mini=1,2,⋯,n.(3)
NormalizeW¯=W¯1,W¯2,⋯,W¯nT vector: (4)Wi=W¯i∑j=1nWji=1,2,⋯,n,W¯=W¯1,W¯2,⋯,W¯nT is the required feature vector.(4)
Calculate the largest characteristic root of the judgment matrixλmax: (5)λmax=1n∑i=1mBWiWiwhereBWi represents the ith element of the vector BW.(5)
Consistency inspectionCalculate the consistency index CI:(6)CI=χmax−nn−1.When the judgment matrix is completely consistent, CI = 0.In addition, the average random consistency index (RI) of the determination matrix is determined, and the value of RI is shown in Table1.Table 1

Based on the existing network evaluation model, if considering that the expected output value yp of the network is difficult to obtain, then design “network comprehensive evaluation model input by noninstructors.”


## 6. Conclusions

Based on the evaluation index system of multimedia collaborative architectural design quality, the fault tolerance, and scalability, system security and information delay of wireless multimedia sensor network are evaluated and analyzed in detail to achieve real-time reduction and improve the particle swarm optimization algorithm. Its inherent fault tolerance and scalability are verified. This paper effectively combines the characteristics of the particle swarm optimization algorithm and the multimedia collaborative building itself to evaluate and analyze the domestic multimedia collaborative building design quality. The research we conducted is to combine the intelligence of the group with other evolutionary computing technologies, have independent intellectual property rights, and jointly develop a visual environment that supports innovative design.
