用DC算法求解连续多设施定位问题

Solving a Continuous Multifacility Location Problem by DC Algorithms

Anuj Bajaj, Boris Mordukhovich, Nguyen Mau Nam, Tuyen Tran

摘要:

提出了一种基于混合整数规划和最小化凸函数差算法的多设施定位问题的新方法。解决多设施定位问题的主要挑战来自于其固有的离散性,非凸性和不可微性。我们提供了一个重新制定这些问题的连续优化,然后开发一个新的DC型算法的解决方案,涉及Nesterov的平滑。所提出的算法是计算实现通过MATLAB数值试验的人工和真实的数据集。

英文摘要:

The paper presents a new approach to solve multifacility location problems, which is based on mixed integer programming and algorithms for minimizing differences of convex (DC) functions. The main challenges for solving the multifacility location problems under consideration come from their intrinsic discrete, nonconvex, and nondifferentiable nature. We provide a reformulation of these problems as those of continuous optimization and then develop a new DC type algorithm for their solutions involving Nesterov's smoothing. The proposed algorithm is computationally implemented via MATLAB numerical tests on both artificial and real data sets.
