#### 3.4.2 Sensitivity Analysis of Service Quality Evaluation Index Values  
From the derivation process of the sensitivity analysis formula of the index value of the fresh agricultural produce supply chain platform's service quality evaluation, it can be observed that the sensitivity of the change to the composite score of the target layer and the criterion layer was mainly influenced by the combination of the index weight value, the index change value, the initial index value, and the initial score of the target layer (criterion layer). There was a linear correlation between the integrated score values and the parameters related to the index values.  
More specifically, the comprehensive score values of the target and criterion layers in the service quality evaluation index system were positively correlated with the index weight values, initial index values, and index change values, on the one hand, and they were negatively correlated with the initial score values of the target layer (criterion layer) on the other.  
From the analysis of Figures 1 and 2, it is evident that as the scores of the corresponding index values of the criterion and target layers changed, the changes in the composite scores were analyzed using the weighted average method, and the linear trends of the corresponding composite scores were obtained differently.  
Through the analysis of the trend of change in the scores in the criterion level, the four indexes (namely, the average price advantage of the same category in capital flow coordination, the degree of product integrity in logistics coordination, the level of delivery flexibility in business flow coordination, and the speed of collaborative response in information flow coordination) caused the largest change in trend with regard to the composite score in the corresponding criterion level, and it caused the most obvious sensitivity in the corresponding criterion level.  
We analyzed the changes in the composite score, which were caused by 17 index values in the target layer, and found that the average price of the same category and the convenience of payment in the capital flow, the collaborative response speed in the information flow, and the product integrity in terms of logistics, were the four indexes with the highest sensitivity. Through the evaluation of the service quality of the fresh agricultural product platform supply chain, and the sensitivity changes caused by the index values of \"Fresh Networking\", it was observed that in order to achieve a faster improvement of service quality through lower resource input, the service level indexes of average price advantages in the same category (payment convenience, collaborative response speed, and product integrity) should be improved as a priority.  
Among the four criterion layers, the index value corresponding to capital flow coordination had the most obvious influence on the score of the target layer, and the comprehensive sensitivity had the largest influence on the score of the target layer. In terms of the improvement of the service quality of \"Fresh Networking\", with the retailer as the core and the consumer as the final target, the improvement of the corresponding index of supply chain capital flow coordination should be strengthened first.
