Optimal positioning of safety stocks in MRP

Abstract: The positioning of safety stock in multi-echelon production networks operating in an MRP environment is considered. Our aim is to maximize the service level achieved for a given total amount of safety stock. Most previous research considering MRP environments has been empirical or heuristic, but the approach we take is analytic and concentrates on two network types: serial and divergent networks. Using previous results on the MRP ordering logic, we show that in serial networks the optimal policy positions all safety stock at the end stock-point. This result is independent of the stochastic nature of the demand, the type of uncertainty and the measure of service used. The analysis of divergent networks is more complicated because of the need for material rationing. We show that the optimal policy may depend on the total amount of safety stock available, the variability of the demand, the structure of the lead times, the choice of the rationing policy and the measure of service used.

A performance management framework for healthcare facilities management

Abstract: Purpose – To propose a framework for performance management in facilities management (FM) services in hospitals. Herein, particular attention has been given to domestic services under the area of FM.Design/methodology/approach – The discussions of the paper are based on findings of a mixed methodology approach, i.e. combination of qualitative and quantitative methods. The data sets obtained from mixed methods were subjected to rigorous qualitative and statistical analyses.Findings – A comprehensive performance management framework (PMF) is presented in this paper. The developed PMF is clear, cohesive and can be well understood by all levels of managers and staff. It is well supported by the overall goals of control of healthcare associated infections in domestic services and uses a balanced set of key performance indicators and measures to benchmark the results with one another. The PMF developed gives due cognisance to FM (specifically to domestic services). The successful implementation of this PMF, how...

Comparative Study of Two Techniques of Transit Performance Assessment: AHP and GAT

Abstract: Public transit agencies in the United States have been under mounting pressure to reduce operating costs and subsidies and to improve productivity, ridership, and service levels. Given the growing emphasis on quality and efficiency, there is an impending need to develop a formal procedure to assess transit performance. Considerable disagreement exists among experts about the most effective way to measure transit performance and the degree to which performance may be used as a basis for funding allocation. The purpose of the project that serves as the basis of this paper was to develop a performance assessment tool for Michigan transit agencies that receive operating assistance from the Michigan Department of Transportation (MDOT). In this paper, the writers present the application of two techniques: the Analytic Hierarchy Process (AHP) and the Goal Achievement Technique (GAT) for evaluation of one of the five peer groups specially created for the project. The paper concludes that both AHP and GAT are viable tools for conducting transit performance assessment. Both of them are capable of using a wide range of performance data and developing a composite performance index for each transit agency. The writers, however, recommend AHP as a better multicriteria assessment tool because of its stronger mathematical foundation, its ability to gauge consistency of judgments, and its flexibility in the choice of ranges at the subcriteria level.
