Purpose

Size fit and economic efficiency are two crucial aspects that need to be considered in designing a sizing system. However, there could exist a trade-off between those aspects in order to establish a practical sizing system. The purpose of this paper is to develop a sequential hybrid method of grid and optimization to generate a practical sizing system using anthropometric data.

Design/methodology/approach

The proposed sequential hybrid method consisted of two sequential steps, which employs grid method and optimization method. In the initial step, the grid method creates primary grids that accommodate a designated percentage (e.g. 90%) of users with best size fit. In the subsequent step, the optimization method generated additional grids to provide acceptable fit, with minimum fit penalty scores for users unaccommodated by the primary grids. Our method was applied to the development of a sizing system for men's military jackets. The proposed method performances were evaluated in terms of accommodation percentage, size fit and number of sizing categories.

Findings

Our proposed method resulted in 26 primary grids during the initial step, which cover 90% of users. Next, we generated six additional grids during the subsequent step that provide minimum fit penalty scores for the rest (10%) users.

Originality/value

The main contributions of this paper are as follows: consider accommodation percentage, size fit and number of sizing categories in the design of sizing system; combine the grid and optimization methods and evaluate a sizing system for men's military jackets. The proposed method is applicable to develop optimal sizing systems for multiple-size products.

基于人体测量数据建立实用尺寸系统的顺序混合方法

目的

尺码适合和经济效率是设计尺码系统时需要考虑的两个关键方面。然而，为了建立一个实用的尺寸系统，可能需要在这些方面进行权衡。本文的目的是开发一种网格和优化的顺序混合方法，以使用人体测量数据生成实用的尺寸系统。

设计/方法/方法

所提出的顺序混合方法由两个顺序步骤组成，采用网格方法和优化方法。在初始步骤中，网格方法创建主网格，以容纳指定百分比（例如 90%）的最适合尺寸的用户。在随后的步骤中，优化方法生成了额外的网格以提供可接受的拟合，并为不被主网格容纳的用户提供最小的拟合惩罚分数。我们的方法被应用于男士军用夹克尺码系统的开发。所提出的方法性能是根据适应百分比、尺寸拟合和尺寸类别的数量来评估的。

发现

我们提出的方法在初始步骤中产生了 26 个主网格，覆盖了 90% 的用户。接下来，我们在后续步骤中生成了 6 个额外的网格，为其余 (10%) 用户提供最小拟合惩罚分数。

原创性/价值

本文的主要贡献如下：在尺码系统设计中考虑适应百分比、尺码拟合和尺码类别的数量；结合网格和优化方法，评估男士军用夹克的尺码系统。所提出的方法适用于开发多种尺寸产品的最佳尺寸系统。
