Abstract

In this contribution, we will present the approach used to manage the operational problems of the Laser Guide Star Facility (LGSF) installed in the Yepun telescope at La Silla Paranal Observatory. In this scope we will introduce the Paranal Problem Report System (PPRS) and the LGSF breakdown structure created to track and analyze the technical problems using the PPRS system. The early introduction of this tool has allowed us to accumulate enough data to review the evolution of the LGSF and its respective subsystem based on the problems reports frequency in a monthly basis. The analysis shows the frequency evolution over time considering the complete LGSF system and also the ratio of problems frequency to LGS usage per month. In addition, a cumulative approach is also used to provide information about the fraction of the problems originated by each subsystem since the beginning of the operations.
