N2  - A (Q,R) type policy for a two stage assembly system is developed with constant  demand rate for finished products and stochastic part procurement lead times. In this study the  production was considered as cyclic and continuous. The optimal ordering policies for parts as  well as optimal lot size to produce are considered in order to minimise long-run average cost.  The long run average cost comprises of the setup cost, parts as well as finished product  holding cost and the cost of backlogging. A generalised expression for total cost function per  unit time for general N parts is obtained and the corresponding mathematical formulation is  given, with properties of the objective function. Extensive numerical experiments are presented  for two and three part problems. Explanations for the behaviour of optimal solutions with  regard to model parameter change is presented and some prominent observations are also  given.  The second model with similar structure and decision variables as above but constant  part procurement lead time and stochastic demand for final product is also presented with  characteristics of objective function. Numerical experiment is presented for this for two part  problem. Comparison of optimal solutions with above case is also given
