存在议价能力和副产品协同生产的制造商最优产量决策

考虑由环保型制造商和处理厂构成的两级供应链结构,其中上游制造商进行主产品的生产,而下游处理厂通过对废料加工进行副产品的生产。基于供应链成员之间存在不同议价能力的情形,构建了上游制造商将产生的废料给下游进行处理的协同生产模式,给出了主产品的均衡产量决策和废料的最优交易价格以及制造商关于废料的最优处理策略。研究结果表明,制造商的废料处理策略取决于消费者对副产品产量的敏感程度。当消费者对副产品产量较敏感(不敏感)时,制造商会选择自己处理废料(给处理厂进行加工)。此外,随着制造商议价能力的上升,制造商的均衡利润上升,而处理厂的均衡利润下降。最后发现本文的基本结论在随机产出环境下依然稳健。

The Optimal Production Decision with By-Product Synergy and Bargaining

A two-tier supply chain structure composed of a upstream manufacturer with environmental concern and a downstream processing plant is considered. The manufacturer produces the prime product and generates valuable wastes. The plant may produce the by-product based on the wastes (material) from the manufacturer. Based on different bargaining powers in the supply chain, the by-product synergy production mode is investigated, in which the manufacturer sells wastes to the plant and the plant converts the wastes into a new by-product. The manufacturer's optimal production decision is derived, the optimal trading price of wastes (between manufacturer and the plant) and the manufacturer's optimal waste-disposal strategy. The results show that by-product synergy production is not always better for manufacturer, which is determined by the customer's quantity sensitivity to the by-product. When this sensitivity is high, the manufacturer is more prone to disposing wastes by himself. However, if the customer is less sensitive, the manufacturer will choose the by-product synergy strategy. Meanwhile, as the increase of the manufacturer's bargaining power, the manufacturer's equilibrium profit increases and the plant's profit decreases, respectively. Finally,it is verified that our main results are still robust in random yield scenario.
