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.

• HIGHLIGHTS

• A global quality index (GQI) can solve the baby diaper multi-criterion phenomenon, by using mathematical methodology through desirability functions. This can help hygienic product manufacturers to improve their products to predict costumers’ satisfaction depending on their preferences;

• Baby diaper key properties include liquid absorption, keeping the baby dry, thermal comfort, surface softness, and the structure of the diaper. All properties are converted to individual desirability indexes;

• Our research corroborates that the baby diaper global performance is related to each property. Attributing relative weight to each satisfaction degree by the customer’s affects the final GQI;

• GQI permit the identification of optimal product for the manufacturer on an industrial scale when developing a new product to satisfy the desirability of customers and improve child quality of life.

摘要

一次性尿布是婴儿早期生活中必不可少的产品。今天，它经历了许多发展以提高其性能。在这项研究中，提出了一种旨在解决多准则现象的新方法。开发了一种有用的数学工具，可以根据客户的喜好预测客户的满意度。全局质量指数是通过合意性函数确定的。在这项工作中，选择了五个品牌的婴儿纸尿裤进行检查，由不同的国际品牌制造。将获得的结果转换为单独的合意性指数。最后，通过对个体满意度赋予相对权重，使用几何平均和算术平均聚合来确定全局质量指数（GQI）。确定每个选定婴儿尿布的 GQI。获得的结果允许在开发新产品以满足客户需求时，为工业规模的制造商确定最佳产品。这篇文章也是针对消费者的。GQI 可以帮助他选择最适合宝宝需要的纸尿裤。关于这项研究，模拟了具有最高性能并且非常适合消费者的最高级婴儿尿布结构。

• 强调

• 全局质量指数 (GQI) 可以通过合意性函数使用数学方法来解决婴儿尿布多标准现象。这可以帮助卫生产品制造商改进他们的产品，以根据客户的喜好预测他们的满意度；

• 婴儿尿布的主要特性包括液体吸收、保持婴儿干爽、热舒适性、表面柔软度和尿布的结构。所有属性都转换为单独的意愿指数；

• 我们的研究证实，婴儿纸尿裤的整体性能与每个属性有关。客户对每个满意度的相对权重对最终GQI的影响；

• GQI 允许制造商在开发新产品时在工业规模上确定最佳产品，以满足客户的需求并提高儿童的生活质量。
