A Hybrid Decision Model for Heterogeneous Schemes in "Internet Plus" Hackerspace Product Development

Hackerspace product development helps use the collective intelligence for new product development under the "Internet plus" environment. However, the schemes from the designer collective are numerous, diverse and heterogeneous, how to select the valuable schemes rapidly and intelligently is an inevitable challenge. This paper attempts to propose a hybrid decision model for heterogeneous schemes. Firstly, a hackerspace product development framework is given out based on the "Internet plus" environment, and the schemes decision model is one of the most important components. Secondly, by analyzing the heterogeneous schemes including textual descriptions, sketches and CAD models, three different feature vectors are introduced and combined as a joint computer-aided decision model. Then, a group decision-making model in voting-based method is added for the hybrid model. Finally, an illustrative example is studied to confirm the feasibility of the proposed model in engineering applications.
