摘　　要：为了兼顾护工和老人的主观感受,提出考虑护工疲劳度和老人满意度的多人机协作任务分配框架.考虑护工执行任务前的休息时长、护工和老人之间的好感度、任务难度等因素,建立护工疲劳度的数学模型,结合老人满意度建立多人机协作任务分配多目标优化模型.结合养老情境下常见任务的特点,提出二维双约束编码及其合理初始化和更新方法.基于该编码,采用多目标进化算法对多目标优化模型进行求解.根据min-max与maxmin原则,在Pareto最优解集中确定最终的任务执行方案,以防止出现个体护工疲劳度极大或个体老人满意度极小的情况.仿真结果表明,在提出的养老情境下,“多护工-多机器人”协作的多任务分配框架能够在完成多护工-多机器人团队任务分配的同时,兼顾护工疲劳度和老人满意度、护工总体和个体之间、老人总体和个体之间的平衡.A multi-human-robot collaboration task allocation framework considering both caregiver’s fatigue and elderly satisfaction was proposed in order to balance the subjective feelings of caregivers and elderly people.A mathematical model of caregiver’s fatigue was established by considering factors such as caregiver’s rest duration before task execution,the rapport between caregivers and elderly people,and task difficulty.A multi-objective optimization model for multi-human-robot collaboration task allocation was developed combined with elderly satisfaction.A two-dimensional double-constraint encoding method and its reasonable initialization and updating methods were proposed based on the characteristics of common tasks in elderly care scenarios.A multi-objective evolutionary algorithm was employed to solve the multi-objective optimization model by using this encoding.The final task execution plan was determined from the Pareto optimal solution set according to the min-max and maxmin principles in order to prevent situations where individual caregivers experience extreme fatigue or individual elderly people have extremely low satisfaction.The simulation results demonstrate that the multi-task allocation framework for‘multiple caregivers and multiple robots’collaboration can achieve task allocation within a multicaregiver and multi-robot team in the proposed elderly care scenario while balancing caregiver’s fatigue and elderly satisfaction,as well as maintaining a balance between the overall and individual caregivers,and between the overall and individual elderly people.
