Abstract

Abstract The UN Sustainable Development Goals have recently emphasized the importance of diversity inclusion. Motivated by this goal, we examine the impact of employing individuals with disabilities in apparel manufacturing cells on overall team productivity. We formulate a series of deterministic and stochastic productivity maximization assignment problems to study the impact of disability inclusion on a production line. We extend the baseline productivity maximization formulation to study a multi‐objective problem that simultaneously maximizes productivity, disability diversity, and language diversity. Each analysis is performed across two different garments drawn from a real‐world setting. The models are tested using archival time study data collected in partnership with an apparel manufacturing firm where more than 75% of the billed work hours are from individuals with significant disabilities. The following insights emerge from the analyses. First, the productivity of teams which have individuals across multiple, different types of disabilities is higher than the productivity of teams with employees who share a single, specific type of disability. Second, teams that employ both individuals with and without disabilities perform slightly better than teams that consist of only individuals with disabilities. In some instances, contrary to intuition, teams of only individuals with disabilities even have higher productivity than teams of only individuals with no disabilities. Finally, our results from the multi‐objective problem that simultaneously maximizes productivity, disability diversity, and language diversity suggest that productivity is not generally sensitive to increases in disability diversity. However, productivity is sensitive at extreme levels of disability diversity and language diversity. Limitations and possible future extensions of the study are discussed.

最大限度地提高残疾多样性、语言多样性和生产力:服装制造业的研究

联合国可持续发展目标最近强调了多样性包容的重要性。在此目标的激励下，我们研究了在服装制造单元中雇用残疾人对整体团队生产力的影响。本文提出了一系列确定性和随机的生产率最大化分配问题，以研究残疾包容对生产线的影响。我们扩展了基线生产力最大化公式，以研究同时最大化生产力、残疾多样性和语言多样性的多目标问题。每个分析都是在两种不同的服装上进行的，这些服装来自真实世界的环境。这些模型使用与一家服装制造公司合作收集的档案时间研究数据进行测试，该公司超过75%的计费工作时间来自严重残疾的个人。从分析中得出以下见解。首先，拥有多种不同类型残疾的员工的团队的生产力高于只有一种特定残疾的员工的团队的生产力。其次，同时聘用残疾人和非残疾人的团队比只聘用残疾人的团队表现稍好。在某些情况下，与直觉相反，只有残疾人的团队甚至比只有没有残疾人的团队具有更高的生产力。最后，我们从同时最大化生产力、残疾多样性和语言多样性的多目标问题中得出的结果表明，生产力通常对残疾多样性的增加不敏感。然而，生产力在残疾多样性和语言多样性的极端水平上是敏感的。讨论了本研究的局限性和未来可能的扩展。这篇文章受版权保护。版权所有
