To make products have more added values largely from knowledge and services, service engineering is proposing a method for combining products and services at highly level. When customers use products and services, the customer owes not only a monetary cost but also a lot of non-monetary costs: a time loss, a psychological and physical load, etc. Since such non-monetary costs have a great influence when the customers compare several services, service providers need to take into account them. This paper aims at proposing a model for describing non-monetary costs and classification of them. The presented method is verified through its application to a food processing machine.
