This chapter is the “owner’s manual” part of this book. You might study the physics of dynamic equilibrium, but that does not teach you how to ride a bike. So after months or even years of study and planning, you might know plenty about EMRs, but until you are in the driver’s seat, you really will not know much about how to use them.

Optimal Maintenance in Irrigation
Irrigation and Drainage Systems, 2003This article asks and addresses thequestion ``what is `optimal' maintenance inirrigation.'' It examines alternativedefinitions of irrigation maintenance andexplores pathways of system deteriorationunder alternative input levels. It thendefines maintenance as a service, where thefunctions of arranging, providing, payingfor, and using the service are ...

“Optimal” Policy in a Maintenance Cost Problem
Operations Research, 1967This paper is concerned with estimating the “optimal” policy when the (unknown) cost function C(x) is nonlinear with a single minimum, and can be approximated in the neighborhood of the minimum by a polynomial regression. The value x0, at which C(x) attains minimum, is approximated by ◯0 obtained from the regression function, and the expected value of

Optimal condition-based and age-based opportunistic maintenance policy for a two-unit series system
Computers & industrial engineering, 2019A new optimal maintenance policy considering the condition monitoring and age information is considered for a two-unit repairable system. Unit 1 is the core component of the system, which is subject to soft failure observed only through inspections. Unit

Optimization of Maintenance Resources
Operations Research, 1965Dynamic; programming techniques appropriate to optimizing a maintenance function are evaluated to demonstrate the feasibility of applying them to large-scale systems involving many equipments. The objective is to determine the proper number, mix, and level of military and/or contractor maintenance personnel, and to apportion expenditures on other ...

Optimal maintenance time for imperfect maintenance actions on repairable product
Computers & Industrial Engineering, 2011This paper develops a maintenance strategy for repairable products that combines imperfect maintenance actions at pre-scheduled times and minimal repair actions for failures. Under a power law process of failures, an expected total cost is developed that involves the sum of the total cost of imperfect preventive maintenances and the expected total cost

Towards An Intelligent Maintenance Optimization System
Journal of the Operational Research Society, 1995Summary: This paper is concerned with the evaluation and enhancement of the maintenance routines of large and complex technical systems. An `intelligent decision support system' approach is suggested as a method for overcoming the difficulties associated with the scale, variability and changeability of such systems.

Optimization of the maintenance process
SIMULATION, 1985A comprehensive preventive maintenance program minimizes equipment breakdowns and cuts operating costs, which in turn improves productivity. A mathematical definition of the maintenance process and criteria for its optimization is presented in two stages: (1) struc tural optimization of a maintenance process by selecting an ap ...
