港口主导下煤炭供应链上游供应商的融资决策

Financing Decision-making of Upstream Supplier in Coal Supply Chain Dominated by Sea Ports

针对煤炭供应链上游供应商因资金不足而需借贷时采用的两种融资模式——基于供应链金融的存货质押和民间借贷,以上游供应商的收益为目标函数,以贷款方的审核时间、存货质押率和贷款利率等为决策变量,建立了两种融资模式下上游供应商的融资决策模型,计算了相应的最优融资额和最优煤炭订货量。

This paper constructs different financing decision-making models for the upstream supplier in coal supply chain under two financing models,namely pledge of accounts receivable and private lending,in which the revenue of the upstream supplier is taken as the objective function,and credit audit time,inventory pledge rate and loan interest rate are the decision variables.Based on these,it calculates the optimal amount of financing and the optimal coal order quantities under the two financing modes.
