You Have Collected the Data for a Time-Cost CPM Scheduling

question 34

Multiple Choice

You have collected the data for a time-cost CPM scheduling model analysis. The time is in days and the project "direct costs" are given here. The indirect costs for the project are determined on a daily duration basis. If the project lasts 16 days, the total indirect costs are $400; 15 days, they will be $250; 14 days, they will be $200; and 13 days, they will be $100.
At what day do we achieve the lowest total project cost (i.e., direct plus indirect costs) ?

• A) 16 days
• B) 15 days
• C) 14 days
• D) 13 days
• E) 12 days

Geometric Tolerances

The limits of allowable variation in the shape and size of a part's geometry, including its form, orientation, and location, specified in engineering drawings.

Straightness

A condition where an element or line maintains a consistent path without deviation, typically applied in manufacturing to ensure parts are within specified tolerances.

Flatness

A geometric tolerance that describes how flat a surface must be within specified limits.
