Time-Based Preventive Maintenance Without Time Shifts: A Petri Net Approach to Availability Evaluation
Ilija S. Hristoski, Gordana Janevska, Mitko Kostov · 2025
This paper focuses on the evaluation of a DSPN-based model for time-based preventive maintenance cycles occurring at fixed intervals, integrating failure-repair dynamics and scheduled maintenance. Steady-state analysis reveals that system availability is highly influenced by the interplay of MTTF, MTTR, MTPM, and TTPM, affecting both low- and high-available systems.
