1.10 Optimization of operation
The flow diagram of Fig. 1-1 terminates with the construction or beginning of manufacture of a product or service. Actually another stage takes over at this point, which seeks to optimize the operation of a given facility. The facility was designed on the basis of certain design parameters which almost inevitably change by the time the facility is in operation. The next challenge, then, is to operate the facility in the best possible manner in the light of such factors as actual costs and prices. A painful activity occurs when the project is not profitable and the objective becomes that of minimizing the loss.
