This study proposes a method to evaluate and diagnose the performance of a job-shop that considers production planning and control aspects, such as throughput, delivery reliability and turnaround time. The short-term performance prediction can be used for weekly performance evaluation. The model considers the actual achieved performance instead of average values. The prediction of the throughput and component completion time in the maintenance repair and overhaul MRO job-shop are considered to be the primary performance indicators, from which other measures can be easily derived, such as job-shop efficiency, capacity utilization, delivery reliability, effectiveness and productivity. The model was tested on a case study, an aircraft component MRO job-shop and the results showed a low prediction error and low standard deviation error compared with those of long-term planned performance.
