Abstract: Example computing systems perform functions for calculating a sum representing a value of a system component or a structural component of an aircraft. The functions may include identifying the component for analysis and assigning numerical ratings that pertain to how the component relates to respective criteria. The criteria may include one or more of whether the component is described in an illustrated parts catalog, a reorder lead time, a component class, a price, whether repairing or replacing the component requires taking an aircraft out of service, a quantity of repair authorizations that have been issued for the component, or a quantity of communications regarding the component. The functions may further include calculating a sum of the assigned ratings and, based on determining that the sum exceeds (or is less than) a threshold value, initiating (or ceasing) a process to retrieve or curate one or more instances of the component.
