At the highest level of a FMECA System is the object "Model" 
. This is the basic object to build up a structure of one of the following objects:
Serial systems
Parallel systems
Parts
Clustered Maintenance
A Model has a one to one relationship with a FMECA System. One cannot exist without the other. The Model is the starting point of building a decomposition of a system representing a real-life situation. Building a tree-structure representing the real world enhancing true understanding how the real system functions and may fail.
Creating a Model
To create a new model:
-
Open the FMECA screen.
-
Create an FMECA System. Asset Strategy Optimization will also create a Model carrying the same name as the FMECA System
-
In the Property Grid (see Property Grid and Properties Screen), fill in the name of the FMECA System. For example, Bicycle.
-
Click outside of the name field to save the name
-
Now, select the created Model from the screen.
-
Optionally, provide a description of the Model in the Description field.
Using the Properties Screen:
-
Open the FMECA screen
-
Create an FMECA System. Asset Strategy Optimization will also create a Model, both will not have a name yet
-
Now, double-click the FMECA System in the folder structure.
-
In the Properties screen, add a name to the FMECA System. The Model will be given the same name
-
Optionally, provide a description of the Model in the Description field.
-
Press OK to save the settings, and close the Properties screen.
Tab Model - General
By double clicking the created Model (in the middle of the screen), the Property Screen opens for this Model. Here, details can be added, in different tabs, just like in the Property Grid on the right hand side of the screen. It is possible to give a different name to the Model, which will not be reflected on the name of the FMECA system. It is advised to keep the two names identical. Note that the Property Grid provides an easy way to directly make changes to fields when a Model is selected, where the Properties Screen requires the user to first open it and explicitly save and close the screen afterwards.

FIELD |
DESCRIPTION |
|
Name |
Users are free to enter any name for the object. The logical option is to enter the actual name of the object. |
|
Object type |
Always 'Model' for this Object |
|
Function |
In this field, users can enter a functional description of the object in question |
|
Tag |
The Tag is the number by which the physical object is known within the system Note: The tag value, when entered, will be displayed together with the Name of the object in the tree. |

Buffer time is the period measured from the point at which the subsystem fails to the point at which the entire system will be affected by this failure. The results of the simulation show whether or not there is a buffer time. The time unit can be selected from the dropdown menu: Hours, Weeks, Months, or Years. |
|
(DD/MM/YYYY) |
The Begin Date can be used to enter the date on which the system was put into use. Any change in the Begin Date parameter will be reflected in the results of the simulation of the system or subsystem |

(€/hour) |
Production Loss of a whole Model is defined at this level. During calculations (e.g. during simulation), the downtime of a failing part or component is taken into account. To calculate the production loss for the specific failing part or component, Production Loss is multiplied by the Maintenance time (FBM) and by the Function loss of the corresponding Fail cause or the system is multiplied by this value. To calculate Production Loss per year, the previous number is divided by the MTTF value of the Failure Cause. For Economic Spare analysis (optional module), if the FBM is mitigated by a mitigating action (UBM/CBM), then the Production Loss is reduced to 10% of its initial value. Note: This value is rounded to a whole number, although a decimal number can be entered. |
