The work aims to preferr packaging design solution using TOPSIS comprehensive evaluation method. A comprehensive evaluation model for the packaging solution was established. CRITIC_G1 method was used to assign weights to the indicators at each level. The packaging design solution for a switch was taken as an example. Based on the CPS packaging concept, three transport packaging solutions were designed and the values of their packaging indicators were standardized, the weights of each of the indicators were calculated using a combination of subjective and objective weighting methods, and the user perception data was determined using a semantic difference scale. Finally, the TOPSIS method was used to obtain the advantages and disadvantages ranking of the three solutions. The packaging solution comprehensive evaluation model can make an effective selection among different solutions, and the calculation can get three solutions relative nearness degree as D1=0.42, D2=0.84 and D3=0.52, it can be known that the solution with EPP as cushion material is the optimal transport packaging solution for the switch, and the process and results of the packaging solution preference have greater credibility and reference value. By using the TOPSIS comprehensive evaluation method, each indicator of the packaging solution can be quantified and analysed. The main factors influencing the advantages and disadvantages of a solution are identified, which provide reference values and directions for improvement in the design and selection of similar solutions.
