Ergonomics assessment in the automotive industry has, to date, focused mainly on physical ergonomics, for example, manual handling and posture. However, workload and, in particular, metabolic and cognitive workload, contributes to worker efficiency but has not received sufficient attention to yield practical guidance for industry. Successful workload assessment requires in-depth understanding of the context in which it will be conducted and of the various assessment techniques which will be applied, with consideration given to factors such as feasibility, resources, and skill of the assessor. These requirements are met with challenges within large and complex organizations and are often dealt with in a piecemeal and isolated matter (i.e., reactive workload assessment). The present paper explores these challenges within the automotive manufacturing industry and aims to develop a decision matrix to guide effective selection of workload assessment techniques focused on metabolic and cognitive demands. It also presents the requirements for time, equipment, and knowledge to implement these techniques as part of a participatory ergonomics approach. Early findings suggest that most assessment techniques reviewed require further development, for example, to establish the acceptance criteria for the specific workload scenario. However, five methods (Garg, Borg RPE, IPAQ, SWAT, and NASA-TLX) are ready to use in certain applications. Ultimately, the findings suggest that it is possible to implement a participatory workload evaluation program within large and complex manufacturing plants.

认知和代谢工作负荷评估技术：汽车制造环境中的回顾

迄今为止，汽车行业的人体工程学评估主要关注身体人体工程学，例如手动操作和姿势。然而，工作量，尤其是代谢和认知工作量，有助于提高工人的效率，但尚未得到足够的重视，无法为行业提供实用的指导。成功的工作量评估需要深入了解将进行的环境和将应用的各种评估技术，并考虑评估员的可行性、资源和技能等因素。这些要求在大型复杂组织中遇到了挑战，并且通常在零碎和孤立的问题中处理（即，反应性工作负载评估）。本论文探讨了汽车制造业中的这些挑战，旨在开发一个决策矩阵，以指导有效选择专注于代谢和认知需求的工作负载评估技术。它还提出了将这些技术作为参​​与式人体工程学方法的一部分实施的时间、设备和知识要求。早期调查结果表明，审查的大多数评估技术需要进一步发展，例如，为特定工作负载场景建立验收标准。但是，有五种方法（Garg、Borg RPE、IPAQ、SWAT 和 NASA-TLX）可以在某些应用中使用。最终，研究结果表明，可以在大型复杂的制造工厂内实施参与式工作负载评估计划。
