One kind of scheme in Hotel Guest Room Service and Management System based on CAN bus is presented. The system's structure and main function are expounded. The work principle and design of the system's hardware and software are explained. The realization of the system's hardware and software is detailed from aspects of improving system's anti-jamming and fault self-examined capability, and the block diagram of each part's circuit is given. Finally, features of the system are summarized, and a comparison with the system based on RS485 was made to prove the advantages of the system. By practice, CAN bus in the system can transmit data steadily and reliably.展开更多

As a result, several authors have developed service classification systems, in order to better understand the nature of service operations and provide methods and tools to improve service efficiency and quality. This paper exploits the work resulting from service classification systems and identifies the principal attributes to be considered in service management. The tool introduced for this purpose is the Service Attribute-Process Matrix （SAPM）, which uses selected results from existing service classification schemes to investigate the importance of the significant service attributes to major processes of the service life cycle.展开更多
