基于CRITIC_G1法赋权的包装方案综合评价

目的 运用TOPSIS综合评价方法,优选包装设计方案.方法 建立包装方案综合评价模型,运用CRITIC_G1法为各不同层级的指标进行赋权,以交换机的包装设计方案为例,基于CPS包装理念设计3款运输包装方案,并对其各类包装指标进行标准化处理,使用主客观结合的赋权方法计算各指标权重,用户感受数据运用语义差异量表确定,最后使用TOPSIS法得到3个方案的优劣排序.结果 该包装方案综合评价模型能对不同方案进行有效优选,3个方案所得相对贴进度分别为D1=0.42,D2=0.84,D3=0.52,可知以EPP为缓冲材料的方案为交换机的最优运输包装方案,包装方案优选的过程和结果有较大的可信度和参考价值.结论 运用TOPSIS综合评价方法,可以对包装方案各指标进行量化处理和分析,确定影响方案优劣的主要因素,为相似的方案设计和优选提供参考价值和改进方向.

Comprehensive Evaluation of Packaging Schemes Based on CRITIC_G1 Method

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.
