Application of Decision-Making Trial Evaluation and Analytical Network Process to Fruit Bag in Service Design

We explored the causal relationship and importance of evaluation factors to purchasing decisions taking the service design of Kiwi bag design for consumers as the research object and using decision-making trial evaluation (DEMATEL). The three most important key evaluation factors before purchasing Kiwi bags were found to be “beauty”, “operability” and “durability”. “Beauty” was the influencing factor while “operability” was the main factor. It is recommended to consider these factors to design bags and to investigate possible directions for the evaluation. In the modeling process, it is necessary to quantitatively evaluate simple factors chosen from complex interacting factors and use the results to determine future designs.
