This study addresses the challenge of virtual machine (VM) placement in cloud computing to improve resource utilization and energy efficiency. We propose a mixed integer linear programming (MILP) model incorporating -robustness theory to handle uncertainties in VM usage, optimizing both performance and energy consumption. A heuristic algorithm is developed for large-scale VM allocation. Experiments with Huawei Cloud data demonstrate significant improvements in resource utilization and energy efficiency.
本研究旨在应对云计算中虚拟机（VM）放置的挑战，以提高资源利用率和能源效率。我们提出了一种结合了-稳健性理论的混合整数线性规划（MILP）模型，以处理虚拟机使用中的不确定性，同时优化性能和能耗。针对大规模虚拟机分配开发了一种启发式算法。利用华为云数据进行的实验表明，在资源利用率和能源效率方面有显著提高。
