基于全要素任务模型的肢残者能力——任务匹配度评价方法

Capacity-Task Match Evaluation of Physically Handicapped Based on Total-Factor Task Description Model

肢残者能力-任务匹配度评价是肢残者作业及辅助设计的重要科学依据。如何全面刻画作业系统各要素与肢残者功能间的交互关系是高信度匹配度评价的关键。建立一种肢残者全要素任务模型,通过对作业系统的全局描述,实现多作业要素动态交互组合下肢残者能力-任务的匹配度评价与分析。模型用作业实体、作业本体和作业空间三个作业要素类以及要素间动态逻辑规则描述人-机-环-任务系统,基于三级约束运动模型拟合肢残者能力属性与作业要素的强交互关系,刻画肢残者能力与其它作业要素的匹配度。最后用实例验证模型的有效性。

Capacity-task match evaluation of physically handicapped is vital to appropriate job design and job aid design. High-validity evaluation mainly depends on full description of interaction between work factors and dysfunction of the handicapped. Total factors task description model of physically handicapped is thus built to describe the whole work system and thus evaluate capacity-task match within dynamic integration task system. The model is run based on three work factor categories：task entities, task ontology and task space, together with logical rules regulating dynamic interaction between different work factors to fully describe the work system. Match evaluation between handicapped workers and other work factors is run on a three- level motion-restricting model. Finally, an example is used to validate its applicability.
