Efficiency measurement for mixed two-stage nonhomogeneous network processes with shared extra intermediate

Qingxian AN, Xuyang LIU, Shijie DING

Frontiers of Engineering Management 2020, Volume 7, Issue 2, Pages 259-274 doi: 10.1007/s42524-019-0080-x

Abstract: Unreasonable allocation of shared resources reduces the system efficiency and is a considerable operationalSub-processes with insufficient portion of shared resources could not help accomplish complicated tasks, and overstaffing and idle resources will occur in the sub-processes assigned with redundant sharedThis unfair portion distribution may cause internal contradictions among sub-processes and even leadto the collapsing of the entire system.
