【摘要】：更新产品是基于原产品增加或优化了部分功能的产品。更新产品相对原产品融入了更先进的技术,具有更强大的功能,更能获得消费者的青睐。产品更新换代在各行业中愈演愈烈,以IT行业最为典型,其多以装配产品为主,表现为部件更新引起的产品整体更新。如何正确优化基于部件更新的组装产品供应链中产品动态定价决策,将极大的影响企业的生存发展。针对此问题,本文进行了以下研究:首先,分析了由关键部件更新引起的装配产品更新,在此基础上建立了新旧两代装配产品共存时的装配产品更新供应链模型,该模型由新旧关键部件供应商和新旧产品装配商构成。其次,结合Fisher扩散模型和静态差异产品需求模型建立了新旧两代装配产品处于同一市场时的动态需求函数模型。其中新产品潜在市场需求随时间变化趋势符合S型曲线,时间一定时,新旧两代装配产品潜在市场份额一定,新旧两代装配产品的需求和本身零售价成反比,和竞争装配产品零售价成正比。基于上述供应链模型和动态需求函数模型,研究了装配商非合作情形下的决策问题。通过Stackelberg博弈和Nash博弈获得新旧两代关键部件供应商和新旧两代产品装配商各自制定的最优动态定价和各自动态收益。通过仿真分析获得:原产品供应链中供应商和装配商制定的动态批发价和零售价曲线均随更新产品生命周期而递减;而更新产品供应链中供应商和装配商制定的动态批发价和零售价曲线均随更新产品生命周期而上升。最后研究了装配商合作情形下,研究新旧两代装配产品最优动态定价,并通过仿真分析得到:关键部件的批发价上升或下降幅度大于非合作情形,相反装配产品零售价上升或下降幅度小于非合作情形。装配商的最优收益均大于相应的供应商收益。合作情形供应商的收益均低于非合作情形,而装配商的收益均大于非合作时。市场价格敏感度和功能替代参数越相近,相应的产品需求、批发价、零售价、供应商和装配商的收益越高。
[Abstract]:Update product is based on the original product added or optimized part of the function of the product. Compared with the original products, the newer products have more advanced technology, more powerful functions and more popular with consumers. Product upgrading is becoming more and more intense in various industries, IT industry is the most typical, most of which is assembly products, which is the whole product update caused by component update. How to correctly optimize the dynamic pricing decision in the assembly product supply chain based on component renewal will greatly affect the survival and development of enterprises. In order to solve this problem, the following researches are carried out: firstly, the assembly product update caused by the key component update is analyzed, and then the supply chain model of assembly product renewal is established when the new and the old assembly products coexist. The model consists of suppliers of new and old key components and assemblers of new and old products. Secondly, combined with Fisher diffusion model and static differential product demand model, the dynamic demand function model of the old and new generation assembly products is established when they are in the same market. The trend of the potential market demand of the new product accords with the S curve with time. When the time is fixed, the potential market share of the new and the old generation assembly products is constant, and the demand of the new and the old generation assembly products is inversely proportional to the retail price of the new and old generation assembly products. It is directly proportional to the retail price of competing assembly products. Based on the above supply chain model and the dynamic demand function model, the decision problem of the assembler in the case of non-cooperation is studied. Through Stackelberg game and Nash game, the optimal dynamic pricing and dynamic income of each generation of key component suppliers and assemblers of new and old generations are obtained. The simulation results show that the dynamic wholesale price and retail price curve set by suppliers and assemblers in the original product supply chain decrease with the renewal of product life cycle. The dynamic wholesale price and retail price curve set by suppliers and assemblers in the updated product supply chain increase with the renewal product life cycle. Finally, the optimal dynamic pricing of new and old generation assembly products is studied in the case of assembler cooperation. Through simulation analysis, it is concluded that the wholesale price of key components is higher or lower than that of non-cooperation. On the contrary, the retail price of assembly products increased or decreased less than that of non-cooperative products. The optimal profit of the assembler is higher than that of the corresponding supplier. The profit of supplier is lower than that of non-cooperation, and the profit of assembler is higher than that of non-cooperation. The more similar the market price sensitivity and the function substitution parameter, the higher the corresponding product demand, wholesale price, retail price, supplier and assembler's income.
