Critical analysis of modified grouping efficacy measure; new weighted modified grouping efficiency measure

Abstract Different grouping efficiency measures have been used to evaluate block-diagonal forms in group technology. One of the well-known measures is grouping efficacy. Many grouping efficiency measures were developed in the literature are based on or derived from grouping efficacy. One of these measures is called modified grouping efficacy (MGE). The limitation of MGE measure is that the case of zero efficiency can’t be determined. Moreover, the efficiency of the system is close to zero or very low compared with other measures in the case, where the number of voids is greater than number of exceptions inside the cell. To overcome these limitations, a new measure called weighted modified grouping efficacy is developed in this paper. This measure is tested against some problems from the literature and the results demonstrate the ability of this measure to be used in the evaluation of all types of Structure data.

Downtime Reduction on Medical Equipment Maintenance at The Directorate of Biomedical Engineering in the Jordanian MOH

Medical equipment needs to be managed effectively and carefully from the first step of buying the equipment till being scraped. This includes purchasing procedure, operational procedures and he maintenance policies used in this regards. Managing the maintenance of medical equipment is vital for the patient and for the hospital itself. One of the main problems in healthcare sector today is the availability of medical equipment, which is largely affected by downtime variation needed to repair the medical equipment. This study presents a process improvement study applied on the Downtime of the medical equipments during the maintenance work in the Jordanian of Health Hospitals, based on customized Six Sigma methodology- DMAIC- (Define, Measure, Analyze, Improve and Control). Data was collected from different locations and different equipments to study the problem and make the necessary actions to resolve or reduce downtime. Obtained results indicate that the downtime reduced by 35% by introducing a new procedure to the clinical engineer to used when dealing with any medical equipment for maintenance work.
