✦ Synopsis

We develop estimation methods for continuous-time Markov and semi-Markov non-homogeneous manpower systems using the notion of calendar time divided into 'time windows' by change points. The model parameters may only change at these change points but remain constant between them. Our estimation methods employ a competing risks approach and allow for left truncated and right censored data. Maximum likelihood estimators are given for the hazard and survivor functions describing length of stay in any grade of the manpower system. The models are fitted to data from the Northern Ireland nursing service.

In the present paper, we present the concept of a perturbed non-homogeneous Markov system in continuous time. The expected population structure of the system is found and its asymptotic behaviour is provided under more realistic assumptions than in previous studies, by relaxing the assumption that t

Previous research has shown that the flow of patients around departments of geriatric medicine and ex-patients in the community may be modelled by the application of a mixed exponential distribution where the number of terms in the mixture corresponds to the number of stages of patient care.

In the present paper, the concept of the number of transitions in a non-homogeneous semi-Markov system is introduced. Then the problem of finding the equations that describe the expected population structure, in relation with the number of transitions, is studied. Also, the entrance probabilities of

This paper deals with the computation of the hitting time for a non-homogeneous discrete time Markov chain (NHDTMC or NHMC). We first give the basic definitions of NHMC, then we analyse the hitting time and its survivor function. We also give the sufficient conditions for the existence of the mean h

Given the velocity field of a continuous-time homogeneous Markov system (HMS) with fixed size, it is examined if the system could be considered as a continuum. The model examined is that of a Newtonian fluid. The set of attainable structures is the continuum and its evolution in Euclidean space corr
