Almost all the progressive industries run their manufacturing facilities at a certain optimum level. However, continuous efforts are still necessary to reduce the costs further. An approach is presented in the current paper for benchmarking in engineering manufacture. The manufacturing rate of a product is swapped with that of another appropriate product in the group and this paper provides a theoretical analysis of the effects on the relevant cost. The backorders and their effects on the total cost are included. The non-productive time in a cycle is also emphasized. The procedures are useful for improving the industrial operations further in the different manufacturing situations that they face.
