On this tab you associate a point in the life of the equipment with a condition score that will be assigned to the equipment when that point in life is reached. The Curve Points tab has these important attributes:
-
Point No. - The unique identifier for the curve point. Automatically assigned by the system.
-
Point Value - Enter a value for the point in the life of the equipment. For example, if this record defines the condition score when the equipment is 10 years old, then enter 10. If it defines the condition score when the equipment has driven 100,000 miles, then enter 100,000.
-
UOM - The system will automatically populate this field based on the selection you made for Type, Period Based and Usage Based on the Decay Curves screen.
-
Condition Score - Enter the condition score for the equipment that corresponds to the Point Value, i.e., the point in the life of the equipment. Note that this field will automatically be determined if you used Markov Chains. Note that you can still overwrite this value, even if Markov Chains were used. The system will unselect Auto Generated in that case.
-
State 1 through 10 - These fields will only be populated if you used Markov Chains to determine the curve points. Each column represents the fraction of the equipment in that state at that specific iteration or curve point. For example, if the probability that an equipment in perfect health (state 1) stays in that state 1 is .9 and the probability that it goes to state 2 is .1, then the second curve point will show .9 in state 1 and .1 in state 2. And the next curve point after that will show .81 and .19 respectively, etc.
-
Health Index - Health is calculated as the sum of the state fraction multiplied with the state weight multiplied with 100. For example, if the state 1 weight is 1 and the state 2 weight is .65, then the first curve point’s Health Index will be ( 0.9*1 + 0.1*0.65 ) * 100 = 96.5.
