Priority Order Design Plans of LED Reading Light Using Modified Analytic Network Process Method

摘要

This article proposed a modified ANP (MANP) approach that analyzes the technical words corresponding to the techniques proposed in various technical documents and patents to determine the appearance rates and normalized numerical values of these words. The gaps between the normalized numerical values of different technical words were used to determine the relative importance scales for the technical words. The innovative equations for calculating the weight values are also proposed. LED reading light (LED-RL) were adopted as the target for design improvement. Relevant technical patents concerning three technical categories of overall structural design, heat dissipation, and main body of the LED were collected. Then, the technical categories of LED-RL were used to form three preliminary technical design plans (i,e. Plans A, B, and C). Each plan consisted of two technical categories among three technical categories. Each plan was then processed using the seven steps proposed by the MANP approach to determine the priority weights of the three technical design plans. The technical design plan with highest priority weight was then chosen as the ideal innovative technical design plan.
