# Critical Ratio (CR) Calculation and Job Sequencing ## Objective Calculate the Critical Ratios (CR) for the given jobs and determine the sequence using the Critical Ratio scheduling rule. Note that all responses should be rounded to two decimal places. ## Job Information at Jeremy LaMontagne's Machine Center The following jobs are waiting to be processed: | Job | Date Job Received | Due Date | Duration (days) | |-----|-------------------|----------|-----------------| | 1 | 215 | 260 | 30 | | 2 | 220 | 290 | 20 | | 3 | 225 | 300 | 40 | | 4 | 240 | 320 | 50 | | 5 | 250 | 340 | 20 | Today is day 250. ## Critical Ratio Calculation 1. **Formula for Critical Ratio (CR):** \[ \text{CR} = \frac{\text{Time Remaining}}{\text{Work Remaining}} \] Where: \[ \text{Time Remaining} = \text{Due Date} - \text{Current Day} \] \[ \text{Work Remaining} = \text{Duration (days)} \] 2. **Calculate the CR for each job:** | Job | Time Remaining | Work Remaining | CR Calculation | CR | |-----|----------------|----------------|----------------------------|------| | 1 | 260 - 250 = 10 | 30 | CR = 10 / 30 | 0.33 | | 2 | 290 - 250 = 40 | 20 | CR = 40 / 20 | 2.00 | | 3 | 300 - 250 = 50 | 40 | CR = 50 / 40 | 1.25 | | 4 | 320 - 250 = 70 | 50 | CR = 70 / 50 | 1.40 | | 5 | 340 - 250 = 90 | 20 | CR = 90 / 20 | 4.50 | 3. **CRs Summarized:** | Job | CR | |-----|------| | 1 | 0.33 | |
