This research aimed to propose a new multi-criteria decision-making method called “Decision by Opinion Score Method” (DOSM), which was based on the idea of an ideal solution that has been  utilized for reference comparison. This research used the TOPSIS method to design DOSM because both  depended on an ideal solution to solve the MCDM problem. Meanwhile, TOPSIS consisted of a series of  mathematical operations that has several problems, and DOSM was intended to solve these problems.   DOSM rank was obtained from direct aggregation, or compromise rank, or grey relational analysis.  The case study in a computer network was used in this research which has 9 alternatives (A1- A9)  and four criteria. Three experts were involved in the evaluation for the reference comparison  process to obtain the best alternative. The result of A9 obtained 88.8% in terms of ranking and it  was the best alternative for experts 1 and 3. For expert 2, A1 was ranked as the worst alternati.....
