Abstract: Abstract A manufacturing system consists of operating units which convert their input materials into their output materials. In the problem of designing a process network, we have to find a suitable network of operating units which produces the desired products from the given raw materials. If we consider this process network design problem from a structural point of view, then minimizing the cost of the network leads to an NP-complete combinatorial optimization problem called Process Network Synthesis or PNS problem. In this paper we define an extension of the PNS problem, where probability of failure, operating time and repair time are assigned to the operating units, and some costs are assigned to the system. We provide algorithms that determine the probability of system failure, the operating units which should be used, and the scheduling of the reparation of operating units in order to obtain expected optimal operation of the system.
