Abstract: This work introduces a materials laboratory for civil engineering where the time required to perform each test is not deterministic, likewise the overall performance of this laboratory varies over the time. The process begins by filling out an application and ends with the results report delivery. This article aims to provide the evaluation, analysis and improvement purposes of the service level of the laboratory. First performance indicators were defined and then the simulation model was generated and implemented to estimate the resulting values of the process; next, the system's operations were simulated, different scenarios were assessed, and the service level achieved was calculated. Considering outcomes from simulation process, the system was evaluated and analysed against the overall equipment effectiveness, thus the model provides a decision support tool to identify different configurations to achieve service level expected. Based on the obtained data, service level and key performance indicators were calculated for future scenarios.

Keywords: key performance indicators; KPIs; simulation; work orders; materials laboratory; performance.
