A representation scheme for digital product service system definitions

- Identifies information requirements for the representation of service elements of PSS from literature.
- Proposes a representation scheme for PSS that addresses these requirements.
- Validates the scheme through population with case study data and application in a PSS definition system.
- Defines a benchmark PSS for the evaluation of PSS representation schemes.
- Uses the benchmark to compare the scheme in this paper with previously published PSS meta-models and ontologies.
