For scheduling track maintenance, infrastructure managers perform inspections to assess the condition. When irregularities are higher than threshold limits, a has defect that should be corrected avoid future failures or traffic disruption. Scheduling maintenance actions contribute reliability and availability but demand prediction of evolution degradation. In recent years, several degradation m...

Problem statement: In this article we address the multi-objective Periodic Maintenance Scheduling Problem (PMSP) of scheduling a set of cyclic maintenance operations for a given set of machines through a specified planning period to minimize the total variance of workforce levels measured in man-hours and maintenance costs with equal weights. Approach: The article proposed a mixed integer non-l...

High-Variety, Low-Volume (HVLV) manufacturing systems are built to produce parts of several types in small quantities and under multiple production objectives. They relate to job-shop systems well known by researchers. One of the most studied assumptions of HVLV systems scheduling is considering that machines may be periodically unavailable during the production scheduling. This article deals w...
