Optimal decisions in power battery swapping closed-loop supply chain under different innovation investment modes

This paper researches the impact of different innovation investment modes on the closed-loop supply chain (CLSC) profit and pricing decisions under an uncertain recycling quality background. Furthermore, we construct a battery swapping CLSC under three innovation investment modes. The research results show that: (1) Under the cooperative innovation investment mode, the decision variables and CLSC system profit all reach the optimal level. (2) Increasing the subscription duration can promote the reduction of subscription price, which is beneficial to the improvement of innovation investment level. (3) When the innovation cooperation coefficient is within a certain range, it will promote the increase of profits for the CLSC. (4) The balanced battery ratio is an important factor affecting enterprise decision-making, and it has a more significant impact on the battery swapping operator. (5) The power battery manufacturer can dynamically adjust the echelon utilization quality threshold according to the echelon utilization value to achieve optimal profit.
