讲座摘要：  

We study the group borrowing effect in an assembly chain, where the assembler sources components from complementary suppliers to satisfy future random demand. Due to the long lead time of the component production, the assembler adopts an assemble-to-order (ATO) strategy, where each supplier produces the component to inventory, while the assembler can assemble the final products after observing the realized demand. The assembler offers each supplier a wholesale-price contract now to incentivize them to produce enough inventories. Each supplier may have to borrow bank loans for the production. Using the base case that each supplier borrows separately as the benchmark, we show that, under some mild conditions, the group borrowing of suppliers will result in an increased equilibrium profit of the assembler. However, it may lead to a smaller equilibrium profit of the suppliers in the group, and we modify the wholesale-price contract for the assembler, by adding a fixed transfer payment term, which can incentivize the suppliers to join group borrowing. Our computational study indicates that the assembler can achieve 10% profit improvement, especially when the supplier’s bankruptcy cost is high and the profit margin of the supply chain is low. We note with interest that such pareto improvement opportunity are conditional and mainly depends on the demand distribution: while many commonly applied distributions satisfy the condition, for distributions with the long-tail feature such as Lognormal, group borrowing may result in a significant profit loss of the assembler, which can be more than 10%, quantified by our computational study.
