In a multiple elevator system, which criterion best improves response time when assigning an elevator to a new call?
easy🧠 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify key factors affecting response time
Response time depends on how quickly an elevator can reach the requested floor, which is influenced by its current direction and proximity.Step 2: Evaluate options
Current direction and proximity of the elevator to the request floor considers both direction and proximity, which directly impact response time. Options B, C, and D are irrelevant to immediate response efficiency.Final Answer:
Current direction and proximity of the elevator to the request floor -> Option AQuick Check:
Direction and proximity minimize wait time [OK]
Quick Trick: Choose elevator closest and moving towards request floor [OK]
Common Mistakes:
MISTAKES- Ignoring elevator direction when assigning requests
- Choosing elevator based on irrelevant attributes like color
- Not considering proximity leading to longer wait times
