Stability Analysis of Collaborative Product Innovation Network Exposed to Knowledge Resource Loss

The stability of collaborative organization is crucial for the successful functioning of collaborative product innovation network (CPIN), which is a typical open innovation platform. Knowledge resource loss, especially the human resource and knowledge resource, is the severe challenge for the stability of CPIN. Considering there mainly are two types of elements in CPIN, i.e., members and their knowledge, this paper builds a weighted super-network model for CPIN to integrate the two types of elements. Based on the weighted super-network model, a related nodes removal method is proposed to simulate the member loss and knowledge loss, then the quantitative analytical methods are proposed pertinently to measure and analyze the influence of member loss and knowledge loss on the CPIN stability. The case study results show the methods proposed in this paper can effectively reflect the member loss and knowledge loss, and measure and analyze the influence of their loss on the CPIN stability.
