摘要：The importance of evaluating the effectiveness of the purchasing function in firms along multiple criteria has attracted considerable attention. However, few studies have identified the defining elements that constitute purchasing competence. This paper introduces the construct of purchasing competence using a second-order factor structure derived from purchasing practices identified from the literature. The validity of the construct (purchasing competence) is tested using data from a sample o...

摘要：This paper investigates the performance impact of lot-sizing rule (LSR) selection and freezing of the master production schedule (MPS) in multi-item single-level systems with a single resource constraint under deterministic demand. The results of the study show that the selection of LSRs and the parameters for freezing the MPS have a significant impact on total cost, schedule instability, and the service level of the system. However, the selection of LSRs does not significantly influence the s...

The rise of Britain in the Industrial Revolution and the rapid overtaking of Britain by the United States and Germany are argued to be thoroughly consistent with Swift, Ever Flow, thereby vin...
