摘要 为刻画制造业服务化过程中制造商和销售商的行为策略,文章构建了考虑双渠道产品服务交易的多制造商与销售服务集成商的产品服务供应链网络,建立了基于变分不等式的网络均衡模型,藉此分别刻画制造商层、销售服务集成商层和需求市场的最优行为和均衡条件。通过修正投影算法进行数值算例仿真,研究结果表明:在满足网络整体均衡条件下,各层决策者之间的产品交易量和服务水平达到一定规模时,决策者之间的利益才能得到均衡分配;相较单渠道销售,双渠道产品服务供应链网络中制造商向客户提供的服务水平更具专业性,同时市场需求均衡价格在多重竞争下表现较低;服务水平直接影响着网络效应,增加对客户的服务水平有助于制造商和销售服务集成商获得更高的收益。 In order to describe the behavior strategy of manufacturers and sellers in the service process of manufacturing in-dustry, this paper constructs product-service supply chain network of multi-manufacturer and sales service integrators consider-ing dual channel product service transactions. Then the paper constructs the network equilibrium model based on variational in-equality to characterize the optimal behavior and equilibrium conditions for the manufacturer, the sales service provider, and the demand market respectively. Finally the paper carries out a numerical simulation by modifying the projection algorithm, and the results show that under the condition of satisfying network equilibrium, and when the volume of products and the level of services between decision makers at all levels reaches a certain scale, the interests of decision makers can be evenly distributed;compared to the single channel sales, the service level of the manufacturers in the dual channel product service supply chain is more profes-sional, at the same time, the equilibrium price is lower under multiple competitions;service level directly affects network effect, increasing service level to customer helps manufacturers and sales service integrators to obtain higher returns.
