The third part is Prof. Hu Bin's lecture "Managing Self-Replicating Innovative Goods", chaired by Prof. Wu Xiaole of Fudan University.Inspired by 3D printing technology and innovative agricultural and pastoral products, Professor Hu bin studies the best production and marketing decisions for manufacturers of self-replicating innovative products.The continuous sequential optimal control framework is used to combine the production side self-replication model with the demand innovation diffusion model.The results describe the manufacturer's optimal production and sales strategy, and further verify the robustness of the results under the conditions of demand backlog, liquidity constraint, random innovation diffusion, start-up inventory decision and exogenous demand.

After the report, the teachers and students had a lively discussion and exchange, which inspired us deeply.In the end, Professor Yan Zhijun, Party Secretary of school of Management and Economics, summed up the salon, announced the successful opening of the salon, and once again expressed his heartfelt thanks to the invited experts.
