具有广义界约束的二次不可分资源分配问题

Quadratic nonseparable resource allocation problems with generalized bound constraints

Martijn H. H. Schoot Uiterkamp, Marco E. T. Gerards, Johann L. Hurink

摘要:

我们研究了一个二次不可分离的资源分配问题,出现在该地区的分散能源管理(DEM),在电力网络的不平衡,以最小化。在这个问题中,给定的资源被分配到一组被划分为子集的活动上,并且成本被分配给同一子集内的活动的资源的总分配量。我们推导出两个有效的算法,$O(n\log n)$最坏情况下的时间复杂度来解决这个问题。对于所有子集具有相同大小的特殊情况,这些算法中的一个甚至在给定子集大小的线性时间内运行。这两种算法的灵感来自于可分离凸资源分配问题的断点搜索法。真实和合成数据的数值评估证实了这两种算法的理论效率,并证明其适用于集成DEM系统。

英文摘要:

We study a quadratic nonseparable resource allocation problem that arises in the area of decentralized energy management (DEM), where unbalance in electricity networks has to be minimized. In this problem, the given resource is allocated over a set of activities that is divided into subsets, and a cost is assigned to the overall allocated amount of resources to activities within the same subset. We derive two efficient algorithms with $O(n\log n)$ worst-case time complexity to solve this problem. For the special case where all subsets have the same size, one of these algorithms even runs in linear time given the subset size. Both algorithms are inspired by well-studied breakpoint search methods for separable convex resource allocation problems. Numerical evaluations on both real and synthetic data confirm the theoretical efficiency of both algorithms and demonstrate their suitability for integration in DEM systems.
