1. What is the Period Index Formula?

The Period Index formula calculates the summation of all contributors in period configuration parameters, considering design, weight, and cost factors with their respective priorities. It provides a comprehensive assessment of design performance on a scale of 0-10.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Period Index = \frac{(Minimum Design Index \times 100) - (Weight Index \times Weight Priority) - (Cost Index \times Cost Priority)}{Period Priority} \]

Where:

Minimum Design Index - Comparable quantity in conceptual design phase (0-10 scale)
Weight Index - Summation of weight configuration parameters (0-10 scale)
Weight Priority - Priority factor for weight (% scale)
Cost Index - Summation of cost configuration parameters (0-10 scale)
Cost Priority - Priority factor for cost (% scale)
Period Priority - Priority factor for time period (% scale)

Explanation: The equation balances design quality against weight and cost constraints according to user-defined priorities.

3. Importance of Period Index Calculation

Details: Accurate Period Index calculation is crucial for evaluating design performance, optimizing resource allocation, and making informed decisions in conceptual design phases.

4. Using the Calculator

Tips: Enter all index values on 0-10 scale, priority values as percentages (0-100). All values must be valid positive numbers with Period Priority > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the 100 multiplier?
A: The 100 multiplier scales the Minimum Design Index to match the priority percentage scales used for weight and cost factors.

Q2: What are typical values for priorities?
A: Priorities typically sum to 100% across all factors, representing the relative importance of each design consideration.

Q3: How should index values be determined?
A: Index values are typically assessed by experts based on design requirements, with 10 representing optimal performance and 0 representing unacceptable performance.

Q4: Can this formula be used for other design metrics?
A: While specifically designed for period configuration, the formula structure can be adapted for other multi-criteria design evaluations.

Q5: What if the result is negative?
A: Negative results indicate that weight and cost constraints outweigh the design benefits given the specified priorities, suggesting need for design improvement or priority adjustment.
