Abstract
To solve current social problems, manufacturers need to supply service rather than materialized
products to consumers. We have been proposing a novel engineering paradigm to deal with
services, service engineering. We define services as a state change. A service model consists of three
sub-models: scope model, view model and flow model. A computer-aided design tool, called Service
Explorer, is developed to represent a network of the parameters and determines the influence weight
one another.
