Prioritizing and aggregating interacting requirements for product-service system development

作者：

Highlights：

• Requirements prioritization and aggregation are conducted for product-service system (PSS).

• Rough-fuzzy DEMATEL is used to determine weights for interacting PSS requirements.

• Choquet integral and fuzzy measures are applied to aggregate PSS requirements.

• 2-order interactions between any two requirements are explicitly modeled.

• The method is applied to evaluate requirement interactions for a smart wearable medical system.
