Although pull production systems, such as kanban and CONWIP have been implemented in some production systems with positive outcomes, failure cases have also been reported. To find out the reason, a fundamental study of pull systems is conducted based on the insight from queueing theory. The...

This study considers a two-mode production system that allows the supply chain to utilize a fast reactive production with improved demand information before the selling season. However, the reactive production quantity is limited by the required preprocessing decision before the demand...

Effective benchmarking requires standards for measuring performance across a broad range of organizations. Industry benchmarking measures the relative performance levels of similar operations, but the difficulty of gathering sufficient data to robustly characterize best performance is the...

In the use of peer group data to assess individual, typical or best practice performance, the effective detection of outliers is critical for achieving useful results, particularly for two-stage analyses. In the DEA-related literature, prior work on this issue has focused on the efficient...

Super efficiency models are useful for computing the Malmquist index and in methods for outlier detection, but conventional super-efficiency models may not have feasible solutions for some data sets. We show that a hyperbolic orientation eliminates the infeasibility problem, and permits...
