TWO INNOVATIVE COALITION FORMATION MODELS FOR DYNAMIC TASK ALLOCATION IN DISASTER RESCUES

This paper addresses the problem of multi-objective coalition formation for task allocation. In disaster rescue, due to the dynamics of environments, heterogeneity and complexity of tasks as well as limited available agents, it is hard for the single-objective and single （task）-to-single （agent） task allocation approaches to handle task allocation in such circumstances. To this end, two multi-objective coalition formation for task allocation models are proposed for disaster rescues in this paper. First, through coalition formation, the proposed models enable agents to cooperatively perform complex tasks that cannot be completed by single agent. In addition, through adjusting the weights of multiple task allocation objectives, the proposed models can employ the linear programming to generate more adaptive task allocation plans, which can satisfy different task allocation requirements in disaster rescue. Finally, through employing the multi-stage task allocation mechanism of the dynamic programming, the proposed models can handle the dynamics of tasks and agents in disaster environments. Experimental results indicate that the proposed models have good performance on coalition formation for task allocation in disaster environments, which can generate suitable task allocation plans according to various objectives of task allocation.

The integrated circular economy model of farming and stock raising(ICEMFSR)has attracted increased attention as an effective model for solving the current irrational allocation of agricultural resources and realizing the agricultural value-added industrial *** study uses emergy analysis to comprehensively examine and evaluate the economic benefits,environmental pressures,and sustainable development levels of ICEMFSR in Shucheng County,*** results show that the ICEMFSR possesses the value of popularization with optimally allocated resources in the studied region,in which the emergy yield ratio(EYR),emergy loading ratio(ELR),and emergy sustainable index(ESI)in this model accounted for 3.59,1.25,and 2.89,*** result indicates a leading position in the national agricultural ***,this study constructs a new model based on the coupling of emergy evaluation and multi-objective linear programming to study ***,the EYR,ELR,and ESI respectively varied by +24.23%,10.40%,and +38.06%after replanning of *** variation implies a significant improvement in the sustainable development level of the *** addition,the optimized scenario design for key substances is proposed based on traceability and the reduce-reuse-recycle principle,including biogasification of crop straw and enhancement of crop scientific planting capacity.

科学合理的手术排程对医院和患者双方都具有重要意义。考虑手术室数量有限不确定因素造成手术时间波动及紧急病患随机到达的情况，以医院和患者双方利益最优为目标，建立多目标线性规划模型，利用蚁群算法对模型进行求解得到最优排程方案。并结合某医院手术数据进行仿真测试，实例验证了该排程方法的优越性及应对不确定因素干扰的动态调度优化效果，最后对模型中的相关因素进行灵敏度分析，证明提出的动态优化方法可应用于不同具体情境下的手术排程问题中。

关键词：手术排程多目标线性规划蚁群算法灵敏度分析 surgical scheduling multi-objective linear programming the ant colony algorithm sensitivity analysis
