Supply chain coordination of incomplete preventive maintenance service based on multimedia remote monitoring

摘要

Manufacturing relies on the Internet of things and intelligent internet technology to provide users with remote monitoring services and early warning of failure, to ensure the smooth operation of the equipment. Based on this background, this paper takes equipment user (customer) and maintenance service provider (agent) consist of the two-stage maintenance service supply chain as the research object. A model is proposed for the maintenance service contracts design, optimization under decentralized decision-making and centralized decision-making. The model is developed under the assumption that there is one customer and one unique service provider who is the Original Equipment Manufacturer (OEM) and is called the agent in this paper. Besides, an extensive sensitivity analysis is performed to examine the impact on the improvement factor of the model output. Under the selective maintenance service outsourcing strategy, the agent makes the price of incomplete preventive maintenance, and the customer decides the incomplete preventive maintenance cycle and the times according to the price. Confronting the equipment failure, customer self-repair service and commitments for the loss of equipment downtime, the customer decides the optimal maintenance services prices, and the agent decides the optimal numbers and the cycles of the preventive maintenance service (equipment life).
