电子市场与期权合约市场并存下的供应链优化

在电子市场与期权合约市场并存条件下,构建供应商的生产成本函数模型,找出供应商的最优产能决策,分销商的最优期权订货量决策,集成化供应链的最优产能决策等.然后借助数值分析,找出供应商的最优期权合约参数,及各最优解的变化规律.分析得到,电子市场准入程度的增大、电子市场价格的增大都会促使供应商提高产能;电子市场价格的增大、供应商期权预订价格的降低、期权执行价格的降低、终端市场需求的增大都会促使分销商增大期权订货量和期权执行量,供应商应选择(期权预定价格较小,期权执行价格较大)的优化决策,并针对不同的市场风险选择不同的期权合约参数组合.

Optimal Strategies of Supply Chain in both Option Contract Markets and Electronic Markets

This paper studies optimal strategies of a supplier-distributer system both in option contract markets and electronic markets. It develops a supplier's average total cost function firstly, which helps to work out the supplier's optimal capacity. And expressions for the distributer's optimal option order quantity, the centralized system's optimal capacity are derived secondly. Finally, by numerical experiments, the paper concludes that, increasing either the electronic markets entry or the price of electronic markets will improve the supplier's capacity; decreasing either the supplier's option reservation cost or option execution cost, increasing either the price of electronic markets or the demand of terminal markets, either of which will improve both the distributer's option order quantity and option execution quantity; the supplier's optimal parameters strategy is that option reservation cost should be low and execution cost should be high, and different option optimal parameter strategies should be -framed to accommodate terminal markets' risks.
