Improved Ant Colony-Genetic Algorithm for Information Transmission Path Optimization in Remanufacturing Service System

Abstract

The information transmission path optimization (ITPO) can often affect the efficiency and accuracy of remanufacturing service. However, there is a greater degree of uncertainty and complexity in information transmission of remanufacturing service system, which leads to a critical need for designing planning models to deal with this added uncertainty and complexity. In this paper, a three-dimensional (3D) model of remanufacturing service information network for information transmission is developed, which combines the physic coordinate and the transmitted properties of all the devices in the remanufacturing service system. In order to solve the basic ITPO in the 3D model, an improved 3D ant colony algorithm (Improved AC) was put forward. Moreover, to further improve the operation efficiency of the algorithm, an improved ant colony-genetic algorithm (AC-GA) that combines the improved AC and genetic algorithm was developed. In addition, by taking the transmission of remanufacturing service demand information of certain roller as example, the effectiveness of AC-GA algorithm was analyzed and compared with that of improved AC, and the results demonstrated that AC-GA algorithm was superior to AC algorithm in aspects of information transmission delay, information transmission cost, and rate of information loss.

Research on statistical method of channel information transmission risk probability in large-scale wireless communication system

“…Call the data collection module to collect the original data, the intrusion detection system collects the external threat data in real time, the configuration verification system checks the internal configuration of the target host regularly, and returns the configuration results.The external threat data is the model observation value, the internal configuration is the internal threat data, and the internal and external cause correlation matrix is calculated with the external threat data.After the channel information data is obtained, the internal and external correlation matrix, observation value output matrix and initial state probability are called to calculate a new real-time state transition matrix according to the system changes caused by internal and external threats. Finally, the real-time risk total value of the target host is calculated based on the model algorithm combined with four probability matrices [10].Taking the interruption risk of large-scale wireless communication system channel as an example, if the channel remains constant during the transmission of the whole codeword, the interruption probability can be used to evaluate the system performance, and the corresponding interruption risk probability can be expressed as:…”
