The identification of communities is significant for the understanding
of network structures and functions. In this study, we propose a framework to
address the problem of community detection in bipartite networks based on principal
components analysis. We apply the algorithm to real-world network data, showing
that the algorithm successfully finds meaningful community structures of bipartite
networks. |

Based on the characteristics of product innovation design,
product innovation was designed into several stages: requirements analysis,
problem-finding, problem-analyzing, problem-solving, innovative solution-generation
and solution-evaluating. To help designers find problems, analyze the problems
and solve the problems, the innovation model based on problem-solving was developed
and the approaches to find problem were presented. In addition, different types
of problems in product innovation design were analyzed; a systematic model supporting
problem representation was put forward. Based on internal variable of the problem,
the problems were divided into four grades and the strategies for solving each
grade of problems were presented. Besides, several examples were cited to demonstrate
the feasibility of the models and methods. Finally, a preliminary prototype
software system of computer-aided design for product innovation was developed. |
