The contest problem comes from actual business scenario where AliYun Cloud provides full-cycle technical services to many companies, government agencies, and developers around the world. Among them, service scheduling optimization is one of the cores of improving customer experience. However, in face of immense service volume, largely differentiated regions and languages, diverse customer issues, complex service scenarios, and technical personnel with their own strengths, how to ensure the rapid distribution of massive service while being able t.o efficiently match service scenarios with the capabilities of technical experts is a difficult point in the service scheduling optimization algorithm. This service scheduling competition focuses on the combination of production, research and learning, and provides valuable experience for the development of "digital intelligence service" industry in China.

The competition has lasted three months and have attracted 1381 teams from more than 100 universities and enterprises, including Tsinghua University, Peking University, University of Science and Technology of China, Zhejiang University, Shanghai Jiaotong University, Nanjing University, Xi'an Jiaotong University, Huazhong University of Science and Technology, National University of Defense Technology, etc. Our team proposes a task scheduling method combining particle swarm optimization and shallow neural network. We constructed a new operator to replace the complex nonlinear relationship of deep neural networks and used particle swarm optimization to solve the difficult problem of BP back propagation in NP problem. Our team proceeded to the final since we won the sixth place in the preliminary round and topped at the third place in the second round. In the final, our team has been awarded the bronze medal with the total score ranking as the fourth.
