With the deepening development of global economic integration, supply chain management is becoming increasingly important in logistics. This article explores the mathematical construction and analysis of a supply chain model for logistics development based on time series. Firstly, we introduced the basic concepts and construction methods of supply chain models, emphasizing the importance of time series analysis in logistics development. Next, we proposed a logistics development supply chain model based on time series and detailed its mathematical construction process. Finally, we validated the effectiveness and superiority of the model through empirical analysis. Read More Read Less

Abstract This paper analyses some position control algorithms for 2-coordinate electrical drive systems. We have developed computer simulation models with different types of motors and conducted detailed studies using computer simulation and experimental research. The results can be used to design and fine-tune these electric drive systems with position control.... This paper analyses some position control algorithms for 2-coordinate electrical drive systems.
