#### 3.4.3 Sensitivity Analysis of Evaluation Index Weights  
1. Different trends were observed in relation to the impact of changes in index weights on the overall score. Combined with the weighted average method, we continued to analyze the specific impact of the weights of the evaluation indexes on the service quality of the \"Fresh Network\" project. The weights corresponded with the coordination of the four aspects in the criterion layer, and they were in accordance with the

Figure 2: Trend of changes in overall service quality score due to changes in index scores. aforementioned weight change rules; therefore, the corresponding index weights in the index layer changed from 0 to 1 in units of 0.01, and we calculated the changes in the corresponding indexes in the capital flow, logistics, business flow, information flow, and target layer, as well as the criterion layer, to ascertain the overall score. The impact of the change on the corresponding indexes, and subsequently, on the composite score, was calculated. The effects of the changes on the corresponding index weights and on the composite score are shown in Figures 3 and 4. From the analysis of Figures 3 and 4, it is evident that, with the changes in the weights of the corresponding indexes in the criterion and target layers, the changes in the composite scores were analyzed using the weighted average method, and the trends of the corresponding composite scores were different. Figure 4: Summary of changes in the composite score due to changes in the weight of each index. Figure 3: Changes in composite scores due to changes in index weights at each criterion level. Among them, the trend of change in the composite score was caused by the weighting of three indexes, namely, flexible payment ability, refund timeliness, and payment convenience in the coordination of capital flow; the trend of change in the composite score was caused by the weighting of two indexes, namely, distribution and processing ability and freshness delivery ability in the coordination of logistics; the trend of change in the composite score was caused by the weighting of three indexes, namely, flexibility level in terms of varieties, flexibility level in terms of quantity, and consumption time length in the coordination of business flow. In the coordination of information flow, the frequency of information exchange, the reliability of information processing, and the level of information system, caused by the weighting of three indexes, had a greater tendency to change. Combining all 17 indexes in the target layer, the weights of the indexes related to capital flow and logistics in the criterion layer had the most obvious influence on promoting the comprehensive score, and they were also important elements to ensure the stable development of the fresh agricultural produce supply chain platform. 2. The research considered the changes in the weights of the service quality evaluation indexes and their initial values to jointly contribute to the trend of change of the composite score. Considering the weight changes and their initial values, in accordance with the weighted average method, we continued to calculate the corresponding weight changes in the corresponding criterion layers of capital flow coordination, logistics coordination, business flow coordination, and information flow coordination; the results are shown in Figures 5 and 6, respectively. Considering the influence of the initial value of each index in the index layer, with the change in the corresponding index weights in the criterion and target layers, the sensitivity changes in the corresponding weights were obtained differently.
