Evaluation method of product-service performance

In order to analyse product-service performance (PSP) during product-service systems' (PSSs) running time, a PSP evaluation method is proposed. Interrelationship between a PSS's provider and accepter is defined as product-service relationship (PSR). Concepts of product-service network and product-service chain are put forward to describe interrelationship among PSRs from different perspectives. The concept of PSP is proposed to evaluate interrelationship among PSR. Detailed evaluation indexes are designed to measure the five factors of PSP, including time, quality, cost, stability and reliability. A case study is provided to test the validity and efficiency of the evaluation model of PSP. The analysis results show that the evaluation model can make good efforts in benefiting product-service platform's running, monitoring and optimising.
