-This paper presents an overview of resource optimization approach for transmission system maintenance selection and scheduling. The approach is based on failure rate estimation and risk reduction calculation followed by resource optimization. It also presents probabilistic models developed for circuit breakers and power transformers. An effort is made to quantify the effect of maintenance usin...

Implementation of a condition monitoring system is a difficult decision due to many uncertain parameters. This is certainly the case for the wind turbine industry where factors like long logistical times and weather conditions have a major influence on the economic benefit. One of the parameters that is neglected in most of the available literature is the performance of the condition monitoring...

This paper describes some aspects of a software development toolkit for industrial condition monitoring and maintenance planning applications. The toolkit consists of a graphical Workbench for design and debugging, an Instancer for creating and re-configuring an application and a run-time system for supporting message passing. The software architecture of an application is a distributed system ...

The Department of Defense (DoD) is currently maintaining the aircraft operability and functionality past the original design intention for many military aircraft. This practice imposes an additional burden on the inspection systems at the DoD logistic centers to ensure the aircraft in operation are airworthy and will be able to complete mission assignments for a specified period of time. Condit...

Modern manufacturing systems are characterized by numerous interacting machine tools each with sophisticated maintenance. In order to be competitive, it is possible to reduce the system downtime by applying sensorless automated condition monitoring (SACM). This paper presents newly developed and tested SACM-algorithms based only on signals which are available in position controlled drives such ...

The objectives of our program are 1) to evaluate the cost and effectiveness of the AH-64 (Apache) and UH-60 (Blackhawk) helicopters’ on-board Vibration Monitoring (VM) System, to provide an annual cost savings analysis of the Vibration Management Enhancement Program (VMEP), and to initially correlate vibration signals with the ULLS-A (logistics) database to create a Costs Benefits Analysis (CBA...

In this paper, we consider the joint optimization of economic manufacturing quantity (EMQ) and preventive maintenance (PM) policy for a production facility subject to deterioration and condition monitoring (CM). Unlike the previous joint models of EMQ and maintenance policy which used traditional maintenance approaches, we propose the proportional hazards model (PHM) to consider CM information ...

Real time oil quality monitoring techniques help to protect important industry assets, minimize downtime and reduce maintenance costs. The measurement of a lubricant's complex permittivity is an effective indicator of the oil degradation process and it can be useful in condition based maintenance (CBM) to select the most adequate oil replacement maintenance schedules. A discussion of the workin...

As the share of wind energy increases on the global energy market, the efficient operation of wind farms gains an ever growing significance. Among operational decisions, the planning and scheduling of maintenance operations are crucial for the availability of turbines, as well as for the operational costs. The paper introduces a system that performs the detailed scheduling of maintenance operat...
