In general, data sets are growing larger and larger, and handling related issues is topic of big data. Similar trends and tendencies are evident in data envelopment analysis (DEA). DEA is a well-known instrument for determining the efficiencies of decision-making units (DMUs), applying linear programming. Still, as we will show, DEA suffers notably from the curse of dimensionality. Therefore, we propose improved decomposition-based algorithms involving different termination criteria and multithreading to address this issue. For some of these criteria, we prove the convergence of the algorithm; to the best of our knowledge, we are the first to prove this. Ultimately, from a computational point of view, we study the performance of the new big data strategy by an extensive numerical analysis, thus demonstrating the algorithm’s scalability.

大数据效率分析:涉及大数据集的数据包络分析的改进算法

总的来说,数据集越来越大,处理相关问题是大数据的主题。类似的趋势和趋势在数据包络分析 (DEA) 中很明显。DEA 是一种众所周知的工具,用于应用线性规划来确定决策单元 (DMU) 的效率。尽管如此,正如我们将要展示的,DEA 仍然受到维度诅咒的影响。因此,我们提出了改进的基于分解的算法,涉及不同的终止标准和多线程来解决这个问题。对于其中一些标准,我们证明了算法的收敛性;据我们所知,我们是第一个证明这一点的人。最终,从计算的角度,我们通过广泛的数值分析来研究新大数据策略的性能,从而证明算法的可扩展性。
