However, the analysis is performed in a subjective way, qualitative, and involves several people who analyze piece by piece without a benchmark. During the evaluation of prototypes, designers use criteria such as price, consumption of raw materials, difficulty level of production, quality, and other attributes valued by consumers, as wearability and appearance. Due to this feature, a company develops a large quantity of products, producing prototypes, which are assessed to form the collection. This seasonally feature requires a very fast pace of the process, therefore the process needs to be fast and effective. Furthermore, the traditional seasons are less and less visible than they were before, with frequent changes in season, such as color, shape, texture, label, etc. The entire process runs at least two times per year, one time for each season and with short time-to-market ( Bandinelli et al., 2013). In the fashion industry, the development of products is a dynamic process characterized by a high seasonal demand, which depends on the seasonal nature of fashion products. A line of clothing may be formed by different groups of products that should be administered simultaneously with the process. According to May-Plumlee and Little (1998), the main one is that the industry's products are developed in seasonal lines (collections) rather than individual products. The development of fashion garment products has some peculiarities. In addition, the product development process contributes to maintaining the profitability and flexibility of textile and clothing companies ( Bandinelli, Rinaldi, Rossi, & Terzi, 2013 Senanayake & Little, 2010). The effective management of the apparel industry depends on anticipating consumer needs and desires who need to respond with innovation, with products well designed and executed properly ( May-Plumlee, & Little, 2006). The successful fashion designer has to consider the consumer's needs and, then, create a unique product ( Aktuglu, 2001). It is based both in business talent as intuition and creativity ( Lin & Twu, 2012). The fashion industry is a highly competitive market. Palavras-chave: método de análise hierárquica, tomada de decisão, ferramenta multicritério, desenvolvimento de produto, vestuário. Em seguida, foi aplicado a um estudo de caso real, o qual foi eficiente, permitindo, assim, uma modelagem estruturada do problema, considerando os diversos critérios e incertezas. O modelo foi desenvolvido com base na literatura, e os critérios utilizados foram: aceitação da peça, custo, design e produção. O objetivo principal deste trabalho é a proposta de um modelo para seleção de protótipos para o processo de desenvolvimento de produto do vestuário, baseada em uma ferramenta multicritério: o Método de Análise Hierárquica (AHP). Para o designer, esse processo de seleção é um complexo processo de tomada de decisão no qual é necessário combinar diversos critérios para um público-alvo específico.

Durante esse processo, os protótipos são desenvolvidos, avaliados e selecionados para compor a coleção, e, para a avaliação dos protótipos, os designers utilizam critérios para selecioná-los. Para se manter no mercado, o processo de desenvolvimento de produtos do vestuário de moda desenvolve uma grande quantidades de produtos. Keywords: analytic hierarchy method, decision-making, multi-criteria tool, product and process development, clothing. Then, the developed tool was applied to a real case study and proved to be efficient, thereby enabling a structured modeling of the problem considering the multiple criteria and uncertainty. The model was developed based on literature, and the criteria used were: part acceptance, cost, design and production. Within this context, the main objective of this study was to propose a model for the selection of prototypes in the development process of fashion garment products, based on a multi-criteria tool, the Analytical Hierarchy Process (AHP). For a designer, this process of selection is a complex decision-making, because they need to combine several criteria to attend a very specific target audience. During this process, the prototypes are made, evaluated and selected to compose the collection, thus the designers use some criteria to select them. To remain in the market, the process of development of fashion garment products produces a large quantity of products.
