Blockchain-Enabled Service Optimizations in Supply Chain Digital Twin

Abstract

Digital twin is considered an alternative for optimizing real-world performance within virtual context, which also applies to the optimization of <i>Supply Chain Management</i> (SCM). Blockchain, which facilitates data secure storage and trusted tracking, is deemed to be a proper assistant technology for achieving digital twin implementation. In this work, we propose a blockchain-based digital twin solution to reengineer SCM system, which promotes the digitization and intelligence of SCM to fit in massive service volumes in complex-intercrossed industry system. A strong-weak consensus mode is developed to achieve energy and time savings. We also design intelligent switch-based algorithms to generate time-saving consensus plans under energy constraints. Finally, we set up multiple experiments to compare our algorithm with three baseline algorithms, including <i>Effective Iterative Greedy</i> (EIG), <i>Two Dimensional Genetic</i> (TDG), and <i>High-level Task Scheduling Dynamic Programming</i> (HTSDP). Findings from evaluation demonstrate the potential of our proposed model. Specifically, our algorithm reduces time and energy consumption of EIG algorithm in consensus by 46.84&#x0025; and 16.25&#x0025;, respectively. Compared with TDG algorithm, consensus time and energy consumption of our algorithm are reduced by 50.05&#x0025; and 48.46&#x0025;. Our algorithm cuts down time spent of HTSDP algorithm in generating consensus plan by a factor of 9.88.
