The manufacturer's service to the customer is one of the critical factors in maximizing profit. This study proposes the innovative (, ) inventory policy integrated with autonomated inspection and service strategy for service-dependent demand. First, an advanced autonomated inspection makes the product error-free. Therefore, this makes customers more satisfied and increases profit. The proposed model decides the optimal investment for such autonomated inspection. Second, three types of services are considered in the study: unpaid, partially paid, and fully paid services. Each type of service has a different service level and the amount of the customer's payment. Our model finds the optimal service strategy based on the variable conditions along with the optimal quantity and reorder level of inventory policy. Numerical analyses are made for different service strategies, along with a sensitivity analyses for various critical parameters. Results show that the full paid service is 84.88% beneficial compared to the unpaid service, and the autonomated inspection policy is 5.02% beneficial compared to the traditional ones. The increase in unit servicing costs always increases the profit of the company.
制造商对客户的服务是实现利润最大化的关键因素之一。本研究针对依赖服务的需求，提出了一种与自动化检验和服务策略相结合的创新库存策略。首先，先进的自动化检验使产品无差错。因此，这会让客户更满意并增加利润。所提出的模型确定了此类自动化检验的最优投资。其次，本研究考虑了三种类型的服务：无偿服务、部分付费服务和全额付费服务。每种服务类型都有不同的服务水平和客户支付金额。我们的模型基于可变条件以及库存策略的最优数量和再订购水平，找到了最优服务策略。针对不同的服务策略进行了数值分析，并对各种关键参数进行了敏感性分析。结果表明，与无偿服务相比，全额付费服务的效益高出84.88%，与传统检验策略相比，自动化检验策略的效益高出5.02%。单位服务成本的增加总是会增加公司的利润。
