Using Maintenance Strategy to Improve The Availability of Complex Systems
The availability of complex equipment is affected by both the intrinsic reliability of the system and maintenance strategy. Generally, the reliability distribution of complex repaired systems follows the exponential distribution function. This distribution of failures, at the system level, is a result of having many elements in the system with a mixture of life distributions and or characteristic parameters. When there are many different and non-synchronized life distributions, the hazard rate (failure rate) is constant when measured over a long period. With a constant hazard rate a preventive maintenance strategy is not effective. However, within a complex system, lower level subsystems and components often have well defined wear-out modes of failure. Even though the total system has a constant hazard rate and exponential failure distribution, it is possible to improve equipment availability by managing the repair or replacement of those components with wear-out modes of failure. This paper compares several alternative maintenance strategies and shows how under certain conditions service hours can be reduced and equipment availability increased.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
