In this thesis, closed populations undergoing epidemics will be considered, using the general stochastic epidemic and the corresponding deterministic model. Policies of isolating infectives and immunising susceptibles will be investigated. With costs assigned to the infection, isolation and immunisation of individuals, optimal policies will be found, which at any stage minimise the expected future cost. We shall be concerned mainly with the general stochastic epidemic, but optimal policies for the deterministic model will also be found. The latter will be seen to be similar in form to the optimal stochastic policies and in most cases to provide good approximations to them. An advantage of the optimal deterministic policies is that in general they are much easier to compute than the stochastic ones. We shall also find two optimal immunisation policies for an epidemic with carriers model and use them to derive results for the case of the general stochastic epidemic. We shall provide numerical examples to illustrate and to compare the optimal stochastic and deterministic policies.
