Optimizing resource allocation to best meet system goals is the essence of good engineering. It is the unifying principal in the design of resource-constrained systems such as aircraft, farming complexes, and even military forces. Well-designed systems accomplish tasks using minimal resources. They also dynamically adapt their methods and goals to best use available resources. This is as evident in artificial systems as it is in natural systems. Below, two examples-one a design time problem and the other a dynamic allocation problem-are developed to elucidate the sort of engineering that must be applied to resource management. The first example is a design tradeoff between the efficient use of electric power and the performance of an aircraft. The second example is dynamic allocation of a limited energy budget between cooperating sensors to maximize the quality of the combined measurement.
