How to determine your equipment needs
I recall someone once saying to me that “perception is reality.” But say this to scientists or engineers who need to take experimental data at midnight because their lab equipment is sensitive to even the minutest vibration and they may tell you otherwise. The reality is that imperceptible vibrations can and do impact sensitive experiments, and identifying the sources and selecting the proper e...
متن کاملThe Equipment-Replacement Problem
To illustrate these assumptions, let us consider a simple numerical example. Suppose a car is needed for three years; that is, suppose N = 3. At the beginning of the first year, we have a 2-year-old car. The annual cost of operating a car is a function of its age; and this cost function is given by: c(0) = 10, c(1) = 20, c(2) = 40, c(3) = 60, and c(4) = 70. The fact that these costs are increas...
متن کاملManaging a population of aging equipment requires considering three distinct phenomena: 1) representing the dynamic processes of failure and replacement of the equipment; 2) projecting changing failure rates as equipment ages; 3) balancing the costs of equipment failure with replacement
This paper presents a general decision model that enables utilities to generate business cases for asset management policies, with a specific application to underground distribution cables. The model takes a life-cycle costing approach that enables corporate financial managers and regulators to assess the multiyear financial impacts of maintaining specific classes of power delivery infrastructu...

متن کاملA Markov Model to Determine Optimal Equipment Adjustment in Multi-stage Production Systems Considering Variable Cost
Our aim is to maximize expected profit per item of a multi-stage production system by determining best adjustment points of the equipments used based on technical product specifications defined by designer. In this system, the quality characteristics of items produced should be within lower and higher tolerance limits. When a quality characteristic of an item either falls beneath the lower li...
