Spares Analysis Workflow

This workflow provides the basic, high-level steps for developing Spares Analyses. The steps and links in this workflow do not necessarily reference every possible procedure. For more procedures, see the links in the Related Information section.

To create a Spares Analysis, you must complete the following steps:

Create a Spares Analysis, which contains data for the analysis.
Create a Spare, which contains data about the spare part that you want to analyze. A Spare is used to define delivery time, cost, and spare level data for the spare part that you are analyzing. There might be more than one Spare to represent each spare part related to a piece of equipment.
Create a Spare Application, which contains the failure and repair data for the spare part that you want to analyze. You might have more than one Spare Application for each Spare. For example, a spare part might be used in a piece of equipment that is located in an indoor environment, and the same type of spare part might be used in another piece of equipment located in an outdoor environment. The failure data and repair data might be different for both spare parts. Therefore, you would want to create one Spare Application for the spare part that is used in the indoor environment and another Spare Application for the spare part that is used in the outdoor environment.
Create a Spare Application Population, which contains age data for the equipment that contains the spare part that you are analyzing. A Spare Application Population is used to record the population age of a group of equipment that together use the data in the Spare Application to which it is linked. An analysis might have more than one group of equipment with different ages using the same failure and repair data from the linked Spare Application.
Create one or more Failure Distributions, which allows you to define the ways in which a spare part can fail, requiring a replacement (or repaired to as good as new) spare part. You can define one or multiple Failure Distributions for a Spare Application record, and you can define the Failure distribution manually or by importing the information from an existing Reliability Distribution or Reliability Growth Analysis.
Run the Monte Carlo simulation, which allows you to view the cost differences between spare levels on the Spares Analysis plots.

After you complete these initial steps, you can modify existing records, add additional records, rerun the Monte Carlo simulation, and view the updated results as needed.
