This paper describes a method for apportioning contingency in a probabilistic network. It distinguishes between two requirements for contingency: for high variance crucial activities, and for high float noncritical activities. This enables a logical two-step apportionment, the first based upon...

In a production-inventory system, the manufacturer produces the items at a rate, e.g. R, dispatches the order quantities to the customers in specific intervals and stores the excess inventory for subsequent deliveries. Therefore each inventory cycle of the manufacturer can be divided into two...

The use of networks handling uncertainty to provide a temporal risk analysis of projects is now widespread. However, such analyses frequently give rise to very wide probability distributions, and thus in practice are described as not credible. This is largely because the simulations do not...

In contrast to previous research on HR performance evaluation in quality organisational environments, which is mainly confined to the literature and theory-based studies, this paper provides a partial answer to the question: 'what is a typical quality-oriented HR performance evaluation system'?...

This paper presents key results of a research project on the application of service dimensions and classifications, to study differences between productivity management challenges across 12 important service sectors in the UK. The research methodology was mainly empirical in nature: unlike other...
