流体型排队库存系统是在排队系统中融合了流体库存控制管理的一种随机服务系统，在化工产品生产制造系统、3D打印制造系统，医疗服务系统中和供应链管理等领域有着非常广泛的应用背景。本项目基于流体库存系统的实际应用背景，将排队系统和库存系统交叉融合，从库存策略与定价服务的联合决策的视角，构建流体型排队库存系统新模型。探索系统队长过程和库存水平过程的稳态联合概率的解析求解方法；揭示排队系统性能特征与流体系统的库存管理之间的依赖关系；解析计算系统的有关顾客排队和流体库存的性能指标；研究以定价服务与库存控制策略为决策变量的费用优化问题，研究最优策略结构性质及其优化算法；考察系统参数对排队库存系统性能和最优库存控制策略的影响。本项目的研究成果对于丰富排队库存系统的理论成果，探索排队系统和库存系统理论研究新的发展方向，都具有重要的理论意义，可以为排队流体库存系统的实际应用和优化管理等提供重要理论依据。

The fluid-type queueing inventory system is a stochastic service system that integrate the queueing service of customers with the management of fluid inventory, which have a wide applications in many fields such as chemical production systems, 3D-printing manufacturing system, medical services system and supply chain. Bases on the practical background of fluid inventory, this project integrates the queueing system and the fluid inventory system to establish some new fluid-type queueing inventory models from the view point of joint decision of the inventory policy and service priciing. This project explores analytic method for calculating the steady state joint probability distribution of the queueing length and the on-hand inventory level from the point of the performance analysis, and reveal the relationship between the performance characteristics of queueing system and the management of fluid inventory, and calculate analytically the performance measures related to queueing system and fluid inventory system, study the cost optimization and explore the structure properties of the optimal policy by aiming at the optimization of the service pricing and fluid inventory policy, and investigate the effect of system parameters on the performance and the inventory control policy of the fluid type queueing inventory system. The research results of this project have theory significance for enriching the research achievements of queuing inventory system and finding the new research direction of queueing systems, and further provide important theory basis for the practical application of fluid-type queueing inventory system.
