Tingginya waktu downtime mesin crane di salah satu perusahaan manufaktur produsen baja billet menyebabkan terganggunya kelancaran proses produksi. Untuk mengatasi hal ini serta untuk mencapai kestabilan performa crane, maka perlu adanya tindakan perawatan yang intensif pada setiap komponen crane. Metode Reliability Centered Maintenance (RCM), digunakan mengetahui interval dan dampak positif dil...

Due to unreliable production facility and stochastic preventive maintenance, deriving an optimal production inventory decision in practice is very complicated. In this paper, we develop a production model for deteriorating items with stochastic preventive maintenance time and rework using the first in first out (FIFO) rule. From our literature search, no study has been done on the above problem...

The objective of this work consists in the analysis of reliability in process plants in order to manage the failure risks and avoid them considering the probability of failure among other important criteria. The preventive maintenance is an important function for the better operation of any enterprise; we propose the ranking of process equipment according with their criticality for the operatio...

For leased equipment the lessor incurs penalty costs for failures occurring over the lease period and for not rectifying such failures within a specified time limit. Through preventive maintenance actions the penalty costs can be reduced but this is achieved at the expense of increased maintenance costs. The paper looks at a periodic preventive maintenance policy which achieves a tradeoff betwe...

Efficient and on-time maintenance plays a crucial role in reducing cost and increasing the market share of an industrial unit. Preventive maintenance is a broad term that encompasses a set of activities aimed at improving the overall reliability and availability of a system before machinery breakdown. The previous studies have addressed the scheduling of preventive maintenance. These studies ha...

This thesis deals with the reliability and maintenance of structures that are damaged by shocks arriving randomly in time. The degradation is modeled as a cumulative stochastic point process. Previous studies mostly adopted expected cost rate criterion for optimizing the maintenance policies, which ignores practical implications of discounting of maintenance cost over the life cycle of the syst...
