Tomohiko Sakao

Associate Professor

Developing theories applicable into practice and disseminating cutting-edge insights into industry is at the heart of my research and teaching. I am internationally recognised expert in Ecodesign and Product/Service System.

Sustainable Product and Service System – Crucial for matured economy 

Environmental problems and resource scarcities are growing issues. Innovative ways of providing products and services are needed in order to enhance the global competitiveness of industry in developed countries. Therefore Ecodesign and Product/Service System (PSS) are areas I am interested in, besides I am internationally well recognized and have a strong influence in the research field.

Integrating services with products has become attractive to industry as it could give competitive edge and provides higher value and higher margin – called Sustainable Product/Service Systems (S-PSS). The idea is to make it possible for a firm to increase both profits and customer values while decoupling the economic growth from the environmental impact. S-PSS logically needs to address business models of a firm as well. Since the 1990s, S-PSS has been expected as one of the most effective instruments for moving our society towards a resource-efficient, circular economy.

Development of new scientific insights 

Together with my colleagues I have developed scientific methods that have been utilized and implemented at various manufacturing companies in countries like Sweden, Japan, and Germany. One is called Quality Function Deployment for Environment (QFDE) aiming at effective and efficient incorporation of environmental aspects into product development with extending Quality Function Deployment. Another method called SPIPS (Customer-Oriented Solution Provider – through Integrated Product and Service Development) addresses service (maintenance, repair, overhaul, etc.) aspects in product development. It was among the first developed methods for that purpose. I have written a guidebook for Ecodesign with QFDE being the main method and disseminated QFDE into a number of manufacturers. Implementation of methods in practice as well as knowledge dissemination to industry is an important part of my research. 

My research is financed by European Union, Mistra (The Swedish foundation for strategic environmental research), Siemens, Sveriges Ingenjörer (The Swedish Association of Graduate Engineers), Tekniska verken in Linköping, Toyota, and VINNOVA (The Swedish Governmental Agency for Innovation Systems). 

I am also holding 10 patents in mechatronics control and intelligent machinery. 

Outstanding Researcher in Ecodesign and Product/ Service System

I joined LiU as the Swedish engineers’ (Sveriges Ingenjörer) Environmental Professor in 2007 and have been active in both carrying out projects with industry and publishing academic articles. I have published the highest number of articles in the PSS area worldwide, which is clear evidence of my academic influence and expertise in the field.

Since 2016, I have been elected as Associate Member of CIRP (The International Academy for Production Engineering).

After studying at the University of Tokyo, I worked at Mitsubishi Research Inst., Inc. in Tokyo for 8 full years, where I gained valuable industry experience before beginning my academic career.
