While we all try to read the crystal ball the best we can, predictive modeling can add substance for a decision.ġ) mean arrival time of planes at a airportģ) using the mean time of light bulb, calculate probability of life at specified hours.Ĥ) predicting how long a machine will run before unplanned downtimeĥ) how long until the next email comes through your Inbox at workħ) time between phone calls at a call center All three components of OEE (Availability, Performance, Quality) could benefit from effective probability information.Īn understanding of the probability until a failure or a particular event can be extremely powerful when this information is in the hands of decision makers. When the downtime can be predicted, not only can it control costs but managing labor becomes easier and machine OEE improves. It is a valuable tool to predict the mean time between failures and plays a significant role in Predictive Maintenance, Reliability Engineering, and Overall Equipment Effectiveness (OEE).
This distribution uses a constant failure rate (lambda) and is the only distribution with a constant failure rate. Generally, if the probability of an event occurs during a certain time interval is proportional to the length of that time interval, then the time elapsed follows an exponential distribution. If this waiting time is unknown it can be considered a random variable, x, with an exponential distribution.The data type is continuous.
It's also used for products with constant failure or arrival rates.
The Exponential Distribution is commonly used to model waiting times before a given event occurs. Share Facebook Twitter Pinterest Exponential Distribution
