A Deterministic Maintenance‐scheduling Problem for a Group of Non‐identical Machines

Addresses a deterministic maintenance‐scheduling problem for a group of non‐identical machines. The problem is formulated as a mixed integer non‐linear program which is approached heuristically. In the model formulation, it is assumed that a major overhaul brings the machine back to its new condition, whereas a minor overhaul restores it to a specified operating condition. An iterative solution procedure is developed to obtain a near‐optimal cyclic overhaul schedule. Presents a worked example to illustrate the proposed solution method.
