This formula uses 7 Variables
Variables Used
Weight Index - Weight Index is the summation of all the contributors in weight configuration parameters. The weight configuration parameters are valued on the scale of 0-10 (best=10 and worst=0).
Minimum Design Index - Minimum Design Index is a comparable quantity in conceptual design phase which considers Cost, Weight and Time period indices.
Cost Index - Cost Index is the summation of all the contributors in cost configuration parameters. The cost configuration parameters are valued on the scale of 0-10 (best=10 and worst=0).
Cost Priority (%) - Cost Priority (%) is a factor which shows the priority of cost objective on a percentage scale. It is oriented according to the user's definition of priorities.
Period Index - Period Index is the summation of all the contributors in period configuration parameters. The Period configuration parameters are valued on the scale of 0-10 (best=10 and worst=0).
Period Priority (%) - Period Priority (%) is a factor which shows the priority of time factor on a percentage scale. It is oriented according to the user's definition of priorities.
Weight Priority (%) - Weight Priority (%) is a factor which shows the priority of Weight factor on a percentage scale. It is oriented according to the user's definition of priorities.
STEP 1: Convert Input(s) to Base Unit
Minimum Design Index: 160 --> No Conversion Required
Cost Index: 1327.913 --> No Conversion Required
Cost Priority (%): 10.11 --> No Conversion Required
Period Index: 95 --> No Conversion Required
Period Priority (%): 19 --> No Conversion Required
Weight Priority (%): 15.1 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
WI = ((DImin*100)-(CI*Pc)-(TI*Pt))/Pw --> ((160*100)-(1327.913*10.11)-(95*19))/15.1
Evaluating ... ...
WI = 50.98010397351
STEP 3: Convert Result to Output's Unit
50.98010397351 --> No Conversion Required
FINAL ANSWER
50.98010397351 50.9801 <-- Weight Index

What is Design Index Concept and How to derive Weight index?

At the start of Conceptual Design, the Designer defines Objective index which depends upon the parameters which influence the respective objective. Sum of all of the parameters contributing the objective factor on scale of 1-10 gives objective index. Now this objective index has its own priorities, in a conceptual design model the priorities are shown in percentage. Now how these factor influence the model is given by the product of the objective index and its priority (taken as a number (conversion from percentage)), it is the share of design index. And if the share of design index is subjected to the Cost, Weight and Design Time only, It is called Minimum Design Index. As they are common factors in all type of Aircrafts. The Weight Index can be Derived from the same as we have to modify the formula.
