By the developing and the application of cloud manufacturing, many new business modes based on the IoT, CPS, cloud computing are springing up. It is worthwhile to model a new business mode simulate it to verify the feasibility. In this paper, with a demand of smart devices from a fresh-mix drink company, service agents are used for modeling and a basic comparison model is proposed for the negotiation between service providers to vote for the service provider that best suits the consumer’s demand. A simulation platform that originates from cloud manufacturing is used to simulate the drink ordering, provider negotiation and provider recommendation. Simulation results show that consumers can obtain expected drinks after the negotiations and votes made by providers. Moreover, the system can recommend drinks with different freshness depending on the expiration parameter set by the company.
