Abstract
A disposable diaper is a necessary product in the baby early life. Today, it is subjected to many developments to improve its performances. In this study, a new approach is proposed aiming to solve a multi-criterion phenomenon. A useful mathematical tool permitting the prediction of the customer's satisfaction depending on their preferences is developed. The global quality index is determined through desirability functions. In this work, five brands of baby diapers are selected to be examined, manufactured by different international brands. The obtained results are converted to individual desirability indexes. Finally, geometric and arithmetic mean aggregation is used to determine the global quality index (GQI) by attributing relative weight to individual satisfaction degree. GQI of each selected baby diaper was determined. Obtained results permitted the identification of optimal products for manufacturers on an industrial scale when developing a new product to satisfy customer desirability. This article was addressed also to the consumer. GQI could help him to choose the best diaper for the baby's needs. Regarding this study, superlative baby diapers structure that would have the highest properties and would be ideal for consumers was simulated.
