Embodiment Construction
[0034] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0035] The communication scheme decision-making method based on AHP and TOPSIS includes the following steps:
[0036] Step 1: Select indicators that affect communication quality, such as signal-to-noise ratio, delay, distance, etc., as the basis for decision-making of the optimal communication scheme, and establish a hierarchical model of the communication scheme and its decision-making indicators.
[0037] By analyzing multiple indicators that affect communication quality, a decision-making system for the best communication scheme is constructed. By establishing the hierarchical structure model of each communication scheme and its decision-making index, the decision-making system of the optimal communication scheme is divided into target layer, criterion layer and program layer. Among them, the target layer is an optimal communicat...

The invention discloses a communication scheme decision method based on AHP and TOPSIS. The method includes: comprehensively evaluating a plurality of indexes influencing the communication quality based on an AHP algorithm and constructing a pair comparison judgment matrix; calculating the maximum eigenvalue of the matrix and the corresponding eigenvector; carrying out normalization processing andthen taking the processed data as a weight distribution vector of each decision index influencing the communication quality; constructing a decision matrix by utilizing the selected decision index values influencing the communication quality based on a TOPSIS algorithm, and performing normalization processing; combining with the weight distribution vector of the optimal communication scheme decision index; jointly constructing a normalized weighting matrix about the optimal communication scheme decision index; determining a maximum value and a minimum value in each decision index influencingthe communication quality; respectively forming a positive ideal solution and a negative ideal solution, calculating the Euclidean distance between the positive ideal solution and the negative ideal solution, calculating the relative proximity between each communication scheme and the ideal solution by utilizing the distance, comparing the relative proximity, and taking the communication scheme corresponding to the maximum value in the relative proximity as a final decision result.
Description
technical field [0001] The invention relates to the field of decision-making algorithms and communication schemes, in particular to a communication scheme decision-making method based on AHP and TOPSIS. Background technique [0002] In the process of communication, some objective factors often lead to unsatisfactory communication quality, and it is difficult to guarantee the effectiveness and reliability of communication. In order to ensure high-quality communication, various factors need to be considered, such as transmission speed, communication distance, delay, etc., but the effectiveness and reliability of communication are often contradictory. Therefore, considering multiple factors, it is particularly important to choose a communication scheme that can meet the needs to the maximum extent. Using a reliable decision-making algorithm combined with multiple decision-making indicators to comprehensively evaluate different communication schemes and help us choose a suitable...
