Rajkumar Roy mainly investigates Service, Product-service system, Risk analysis, Process management and Engineering design process. Rajkumar Roy works mostly in the field of Service, limiting it down to topics relating to Operations management and, in certain cases, Service level, as a part of the same area of interest. His Product-service system research includes themes of Product and Operations research.
His research in Risk analysis intersects with topics in Cost estimate, Systems engineering and Phase. Rajkumar Roy has researched Process management in several fields, including Customer retention and Knowledge management. His Engineering design process research incorporates elements of Ontology, Capability Maturity Model and Conceptual design.
His main research concerns Engineering design process, Product-service system, Systems engineering, Risk analysis and Process management. He combines subjects such as Manufacturing engineering, Service and Engineering management with his study of Product-service system. His work in Service is not limited to one particular discipline; it also encompasses Product.
His Risk analysis study often links to related topics such as Cost estimate. His research in Cost estimate tackles topics such as Process which are related to areas like New product development. Process management is closely attributed to Knowledge management in his study.
Rajkumar Roy mostly deals with Augmented reality, Risk analysis, Engineering design process, Human–computer interaction and Nondestructive testing. The concepts of his Augmented reality study are interwoven with issues in Visualization, Multimedia and Software engineering. His Risk analysis study integrates concerns from other disciplines, such as Identification, Uncertainty quantification, Product-service system, Artificial intelligence and Asset.
His Product-service system research focuses on Customer needs and how it connects with Systems engineering. By researching both Engineering design process and Internet of Things, Rajkumar Roy produces research that crosses academic boundaries. His Human–computer interaction research incorporates themes from Implementation, Plan, System model and Flexibility.
Rajkumar Roy focuses on Augmented reality, Composite material, Nondestructive testing, Systems engineering and Industrial maintenance. His Augmented reality study incorporates themes from Visualization and Software engineering. In general Composite material, his work in Carbon composites is often linked to Chemical change, Non destructive, Thermal diffusivity and Design of experiments linking many areas of study.
His Systems engineering study combines topics from a wide range of disciplines, such as Reliability engineering, Product-service system and Process. Rajkumar Roy has included themes like Customer needs and Cost estimate in his Product-service system study. As a part of the same scientific family, he mostly works in the field of Knowledge management, focusing on Process development execution system and, on occasion, Service product management.
