Pricing and Coordination for the Leasing and Recycling of Construction Machinery in a Supply Chain Based on Industrial Internet Platform

Leasing and recycling are important methods for developing the low-carbon sustainability of the construction machinery industry. However, there are some dilemmas caused by the extreme limitations of product service life. There has been little research on construction machinery leasing thus far and a lack of description of its unique characteristics in previous models. Focusing on the problem of pricing and coordination, a two-stage model of a leasing closed-loop supply chain based on the practical application of an Industrial Internet platform was proposed. Under centralized and decentralized decision-making scenarios, the prices of leasing and selling, maintenance effort, and recovery rate were calculated, respectively. By using the Shapley value method to optimize the selling price, and the two-part pricing contract to calculate the compensation fee, global profits can be reasonably distributed, while the supply chain can be improved. The effects of different contracts on the improvement of supply chain profit were investigated. Additionally, the correlation among parameters was explored via sensitivity analysis and numerical simulation. The findings show that the maintenance and recycling of construction machinery can be improved by using an Industrial Internet platform while achieving supply chain coordination via contracts. The enhancement of maintenance effort can decrease remanufacturing costs, which are positively correlated with the selling price and leasing price of products, further promoting the recovery rate of used products. The findings of this paper show that manufacturers can take advantage of the Industrial Internet platform to improve recycling efficiency as well as to decrease product prices and remanufacturing costs by promoting remanufacturing technologies. On the other hand, leasers need to enhance the maintenance of construction machinery. Strengthening cooperation via contracts can jointly promote leasing and recycling in the construction machinery industry and help achieve low-carbon sustainable development.
