It helps to get the best out of what is available. In general, the first option should be to optimise existing operations. Optimisation has to be considered in terms of electrical energy input into a manufacturing process in relation to its output. As in the case of any other resource like money or manpower, optimisation is best achieved through a closed loop system of management. The Elementary Closed Loop System Decisions regarding resource management are made at the appropriate decision making level.
Implementation takes place in the process which handles the resource.
The implementation is monitored continuously, the data is analysed, and the result is fed back to the decision making level. Thus, the decision making level is fully aware of how the implementation is progressing and can initiate corrective action if the original objectives are not being achieved as envisaged. Because of continuous feedback and timely corrective action, the implementation gets progressively refined until a high level of efficiency is achieved. Even after that the feedback has to continue so that this high efficiency is maintained. The result is Open Loop Management as in Fig.
