Design of Smart Service System Based on Kano Model and Calculation of Importance of Function

Objective To study the functional configuration of a smart service system that meets the needs of users, and to propose an improved research method. Methods the Kano model was used to obtain the functional classification of the smart service system based on user needs. The functions in the must-be attribute were retained, pairwise comparison method was used to construct the judgment matrix for the functions in the one-dimensional attribute and attractive attribute, and the square root method was used to calculate the weight of the importance of function, so as to determine the function configuration scheme of the system. Considering the smart kitchen service system as an example, the fuzzy comprehensive evaluation method was used to evaluate the design scheme, and thus verified the feasibility of the method. Conclusion from the perspective of users, combining the advantage of the Kano model in the classification and calculation of the importance of function could easily distinguish the priority of functions in complex systems, and provide a basis for the function design of smart service systems.
