Zorluk: ZorCategorical Classification and Sorting

An airline engineering department classifies aircraft maintenance work orders to determine service queue priority based on three attributes: Safety Impact (Critical vs. Routine), Flight Hours Remaining until threshold (<50, 50–150, >150), and Prior Deferral History (Yes vs. No).

Queue priority is established according to the following strict precedence rules:
1. Work orders with a Critical Safety Impact take precedence over all work orders with a Routine Safety Impact.
2. For work orders with the same Safety Impact, priority is given to fewer Flight Hours Remaining (<50 outranks 50–150, which outranks >150).
3. If work orders have the same Safety Impact and fall into the same Flight Hours Remaining category, a work order with a Prior Deferral History (Yes) takes precedence over one without a Prior Deferral History (No).

Based on these rules, place the following four work orders in sequence from highest priority (first to be serviced) to lowest priority (last to be serviced).

  1. 1Work Order Beta: Critical Safety Impact, 40 Flight Hours Remaining, Prior Deferral: Yes
  2. 2Work Order Alpha: Critical Safety Impact, 40 Flight Hours Remaining, Prior Deferral: No
  3. 3Work Order Gamma: Critical Safety Impact, 120 Flight Hours Remaining, Prior Deferral: Yes
  4. 4Work Order Delta: Routine Safety Impact, 15 Flight Hours Remaining, Prior Deferral: Yes

Cevap

Work Order Beta, followed by Work Order Alpha, then Work Order Gamma, and finally Work Order Delta.
The correct sequence sorts items strictly by the three-tier rule hierarchy. Primary sorting by Safety Impact places Critical items (Beta, Alpha, Gamma) ahead of Routine items (Delta). Secondary sorting by Flight Hours Remaining places <50 hr items (Beta, Alpha) ahead of 50–150 hr items (Gamma). Tertiary tie-breaking places the item with a prior deferral (Beta) ahead of the item without one (Alpha).

Adım Adım Çözüm

1
Evaluate Primary Criterion (Safety Impact)
Work Orders Alpha, Beta, and Gamma have Critical Safety Impact, while Work Order Delta has Routine Safety Impact.
Rule 1 dictates that Critical Safety Impact outranks Routine Safety Impact regardless of other attributes, placing Work Order Delta at the lowest priority (Rank 4).
2
Evaluate Secondary Criterion (Flight Hours Remaining) for Critical items
Alpha and Beta both have 40 hours remaining (<50 bracket), whereas Gamma has 120 hours remaining (50–150 bracket).
Rule 2 dictates that <50 hours outranks 50–150 hours, placing Gamma behind both Alpha and Beta (Rank 3).
3
Evaluate Tertiary Criterion (Prior Deferral History) to break tie between Alpha and Beta
Beta has Prior Deferral: Yes, while Alpha has Prior Deferral: No.
Rule 3 dictates that a prior deferral takes precedence when Safety Impact and Flight Hours Remaining are tied, placing Beta at Rank 1 and Alpha at Rank 2.
