Distinguish repair vs replacement decisions for equipment and provide a simple decision rule.

• A. Replace immediately if any component fails
• B. Always repair regardless of cost
• C. Consider downtime and energy efficiency first
• D. Repair if repair cost is less than 50-60% of replacement cost and equipment has remaining life; otherwise replace

Answer: (D)

The main idea is to weigh repair versus replacement by combining cost, remaining life, and the impact on operations. The simple rule says: look at how much it will cost to repair versus buying a replacement, and consider how long the equipment is likely to stay productive. If the repair cost is less than about 50–60% of the replacement cost and the equipment still has useful life, repair is the sensible choice because you get more years of service at a lower immediate cost. If the repair cost would approach or exceed the cost of a new unit, or the equipment is old, unreliable, or inefficient, replacement tends to be the better long-term value, especially since newer equipment often offers improved energy efficiency and more reliable uptime. In practice, downtime and energy efficiency matter a lot. Downtime lost to repairs can erode production capacity, and energy savings from a newer model can reduce operating costs over multiple years. So the rule captures both immediate financials and longer-term operating performance: repair for moderate, lower-cost fixes on still-useful equipment; replace when repairs are costly or the machine’s life and efficiency are likely to be bettered by a new unit.
