Optimal Recoupment Policy for a Cumulative Damage Model for a Human System in Terms of Aldosterone with Time Deterioration

The replacement problem for shock models under additive damage has been studied by many authors. They have considered the replacement problem where a system is replaced at damage, that have been derived the optimal policy for a cumulative damage model. The authors have considered the replacement problem where a system suffers two kinds of damage and is replaced preventively at age T or at the N shock. According to this formula a human system has been considered two types of damages one with cumulative process and another with at that time of stress effect. Hence a part of the system is recouped by a new concept the expected cost per unit time and optimal values in terms of aldosterone have also been obtained. AMS Classification: 60GXX.
