1. What is the Priority of Objective Cost in Design Process?

The Priority of Objective Cost in Design Process is a factor that shows the priority of cost objective on a percentage scale. It is oriented according to the user's definition of priorities and considers Minimum Design Index, Weight Index, Period Index, and their respective priorities.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

Minimum Design Index - A comparable quantity in conceptual design phase which considers Cost, Weight and Time period indices
Weight Index - The summation of all contributors in weight configuration parameters (0-10 scale)
Weight Priority (%) - The priority of Weight factor on a percentage scale
Period Index - The summation of all contributors in period configuration parameters (0-10 scale)
Period Priority (%) - The priority of time factor on a percentage scale
Cost Index - The summation of all contributors in cost configuration parameters (0-10 scale)

Explanation: The formula calculates the priority percentage for cost objectives by considering the minimum design index and subtracting the weighted contributions of weight and period factors, then dividing by the cost index.

3. Importance of Cost Priority Calculation

Details: Calculating cost priority is crucial for design optimization as it helps allocate resources effectively, balance competing design objectives, and make informed decisions about trade-offs between cost, weight, and time constraints in the design process.

4. Using the Calculator

Tips: Enter all required values with appropriate units. Minimum Design Index and Cost Index must be greater than 0. Weight and Period priorities should be between 0-100%. All configuration parameters are valued on a scale of 0-10 (best=10 and worst=0).

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the 0-10 scale for configuration parameters?
A: The 0-10 scale provides a standardized way to evaluate different design parameters, where 10 represents the best possible value and 0 represents the worst.

Q2: How is Minimum Design Index determined?
A: Minimum Design Index is a comparable quantity derived during the conceptual design phase that considers the combined effects of cost, weight, and time period indices.

Q3: Can the cost priority be negative?
A: Yes, in some cases the calculated cost priority might be negative, indicating that the weight and period factors have higher combined priority than what the minimum design index can accommodate.

Q4: How should priorities be assigned to weight and period factors?
A: Priorities should be assigned based on project requirements and constraints. The sum of all priorities (cost, weight, period) should typically equal 100% for balanced design consideration.

Q5: What are typical values for these indices in real design projects?
A: Values vary significantly depending on the project type and complexity. Generally, higher indices indicate better performance in that particular aspect of the design.
