“From the perspective of logistics, a model of the life cycle of parts in a supply chain can be developed. This model, called the repair cycle, consists of functioning parts in use by equipment operators, and the entire sequence of suppliers or repair providers that replenish functional part inventories, either by production or repair, when they have failed.” Typically, this stage ends with the producer or manufacturer. This form of the model provides scope for demands on a supply system to finally be traced to their functional reliability, providing scope for the dynamics’ analysis of the supply system, in general, spare parts.
The manager should distinguish the state or condition of items in stock to properly manage repairable components. S/he must know if a component is in RFI or request for information condition, being repaired, or requiring repair. The code of supply condition is assigned to classifying the components in terms of their readiness for use and issue. As materials or parts move through the repair cycle, their code of condition changes. The most recent code of condition is used for recording the status of the component or material.
