Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

There are 22 machines and R repairmen in a workshop. The frequency of deterioration is determined by A and the frequency of repair by µ. The disturbances and services are Poisson distribution. Suppose n machines are out of order at a time. Every two hours the machine breaks down and repairs take 12 minutes. How many mechanics (R) should be employed and what is the machine efficiency?
