Abstract. We analyse the point availability of a duplex system characterized by warm stand-by and attended by 2 heterogeneous repairmen. In order to describe the random behaviour of the engineering system, we employ a stochastic process endowed with time dependent transition measures satisfying (coupled) partial differential equations. The solution procedure is based on the theory of sectionally holomorphic functions combined with the notion of dual transforms. As an application, we consider the particular but important case of Erlang repair.
