Robust optimization in warehouse space allocation of pledges in supply chain financing

From the perspective of the supply chain, the storage space allocation model was established based on revenue management. The model aimed at static and dynamic pledge demand by customers in supply chain financing, and introduced a floating stock proportion coefficient to cope with uncertainty in storage space requirements. It was optimized by using the robust optimization method. The warehouse space utilization efficiency of logistics enterprises, which met the demand of the temporary pledge, was improved. Pledge costs were reduced, and the financial benefits of all parties concerned were increased. The robust optimization method has a certain application value in warehouse space allocation of pledges.
