Purpose – This paper aims to reflect on the sources of the technical inefficiency of health care foodservice operations, using a sample of Australian and American hospitals. Design/methodology/approach – The paper applies the stochastic frontier model to reflect on the technical inefficiency...

The aim of this paper is to compare the empirical results from three alternative parametric efficiency models using rank-sum test statistic. The comparison involves the technical efficiency scores and their hospitals ranking of the following models: a) Battese and Coelli (1992); b) technical...

In construction projects, contingency is the budget which is made available to cope with uncertainties that would incur schedule and cost overruns. Contingency estimation requires considering project cost, schedule and technology variability. The effect of dynamic project management of the...

This paper describes a simulation model of community home composting behaviour based on distributions of individual households, each actively managing the organic fraction of their own domestic waste. The model predicts overall participation levels and the individual and collective flows and...

The paper reports the outcome of research to demonstrate the proof of concept for simulating individual, collective and interactive household waste management behaviours to provide a tool for efficient integrated waste management planning. The developed model simulates whole communities as...

Purpose – The aim of this paper is to investigate technical, scale, allocative and economic efficiencies by data envelopment analysis (DEA) and stochastic frontier methods to provide a decision‐making tool and managerial implications in the measurement of farm business performance and...

Purpose – The purpose of this paper is to deal with the application of the stochastic inventory model to the three‐tier supply chain and verify the values obtained by mathematical model in physical simulation. Design/methodology/approach – The paper investigates three‐stage serial supply...
