RAM RAM Life Cycle Cost & Economics 1 — Questions and Answers
Question 1: What does Life Cycle Cost (LCC) analysis encompass in RAM programs?
- Only initial acquisition and procurement costs
- All costs from concept through disposal including acquisition, operation, support, and disposal (Correct answer)
- Only maintenance and repair costs over a system's life
- Only the costs incurred after system deployment
Correct answer: All costs from concept through disposal including acquisition, operation, support, and disposal
LCC captures every cost phase—acquisition, operations and support, and disposal—to reveal the true total cost of ownership.
Question 2: Which LCC cost category covers the initial purchase, installation, and integration of a system?
- Operations and Support (O&S)
- Disposal costs
- Acquisition costs (Correct answer)
- Indirect overhead costs
Correct answer: Acquisition costs
Acquisition costs include design, development, procurement, and initial installation—the upfront investment before the system operates.
Question 3: What is the primary goal of RAM-driven LCC optimization?
- Minimize the initial purchase price regardless of long-term costs
- Balance reliability investment against reduced failure and support costs to minimize total LCC (Correct answer)
- Maximize system performance without regard to cost
- Eliminate all preventive maintenance to reduce expenditures
Correct answer: Balance reliability investment against reduced failure and support costs to minimize total LCC
RAM optimization seeks the sweet spot where investment in reliability reduces downstream failure, maintenance, and downtime costs enough to lower total LCC.
Question 4: In LCC analysis, what are Operations and Support (O&S) costs?
- Costs to design and develop the system
- Costs for fuel, labor, maintenance, spare parts, and sustaining support during operation (Correct answer)
- Costs to safely decommission and dispose of the system
- Costs to market and sell the system
Correct answer: Costs for fuel, labor, maintenance, spare parts, and sustaining support during operation
O&S costs are the recurring expenses—energy, labor, spares, repairs—incurred while the system is in operational use.
Question 5: Which RAM parameter most directly drives operations and support costs in an LCC model?
- Mean Time Between Failures (MTBF) (Correct answer)
- System weight
- Color coding of components
- Number of operators assigned
Correct answer: Mean Time Between Failures (MTBF)
A higher MTBF means fewer failures per unit time, directly reducing corrective maintenance labor, parts, and downtime costs in the O&S phase.
Question 6: How does improving Mean Time To Repair (MTTR) affect a system's LCC?
- It increases acquisition costs with no LCC benefit
- It reduces downtime and labor costs, lowering O&S costs and improving LCC (Correct answer)
- It has no effect on LCC since repair is unavoidable
- It only affects safety metrics, not economics
Correct answer: It reduces downtime and labor costs, lowering O&S costs and improving LCC
A shorter MTTR reduces labor hours, logistics delays, and lost production per failure event, yielding measurable O&S cost reductions across the system's life.
