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。
The ability of the disabled - task matching evaluation is an important scientific basis for the operation and auxiliary design of the disabled. How to fully describe the interaction between the various elements of the operating system and the function of the physically handicapped is the key to the evaluation of high reliability. Through the global description of the operating system, a dynamic interactive combination of multiple operating elements with ability of the lower extremities - evaluation and analysis of the matching degree of the tasks is established. The model uses three job feature classes of job entities, job ontology and job space as well as the dynamic interaction rules between rules describing human-machine-ring-task system. Based on the three-level constrained model, Relationship, depicting the ability of the disabled and other homework elements match. Finally, an example is used to verify the validity of the model.
