Perceived shortcomings in the applicability of capital equipment repla
cement modelling, identified in a 1987 survey within the UK are addres
sed and a robust replacement model formulated. First, however, a compa
rison between the 1987 survey and a similar 1988 survey undertaken wit
hin the USA is made and explanations for apparent differences in concl
usions are presented. A replacement model is then developed in the con
text of medical equipment where factors such as service and risk play
a role in replacement decision-making. A mechanism for quantitatively
allowing for qualitative and for political type factors within a short
time horizon replacement model is introduced by means of a penalty fa
ctor. A case example is presented for medical ventilator equipment.
