![# Job Sequencing and Performance Measures
### Introduction
In this exercise, we will explore how to determine performance measures for different sequencing rules using the Excel Sequencing template. We will focus on three key sequencing strategies: processing in order of arrival, shortest processing time, and earliest due date. Please round your answers to two decimal places.
### Job Details
The table below lists eight jobs, along with their processing times and due dates:
| Job | Processing Time | Due Date |
|-----|-----------------|----------|
| 1 | 7 | 23 |
| 2 | 3 | 9 |
| 3 | 5 | 8 |
| 4 | 2 | 11 |
| 5 | 6 | 16 |
| 6 | 9 | 18 |
| 7 | 14 | 40 |
| 8 | 4 | 31 |
### Sequencing Strategies
#### a. Process in the Order of Arrival
- Measure and compare Flow Time, Lateness, and Tardiness.
- Calculate the average for each performance measure.
**Inputs:**
- Flow Time: ______
- Lateness: ______
- Tardiness: ______
#### b. Shortest Processing Time (SPT)
- Arrange the jobs in order based on the shortest processing time.
- The SPT sequence is: [Select appropriate sequence from options].
**Inputs:**
- Flow Time: ______
- Lateness: ______
- Tardiness: ______
#### c. Earliest Due Date (EDD)
- Arrange the jobs in order based on the earliest due date.
- The EDD sequence is: [Select appropriate sequence from options].
**Inputs:**
- Flow Time: ______
- Lateness: ______
- Tardiness: ______
### Conclusions
- Identify which sequence strategy results in the smallest average flow time.
- Identify which sequence strategy results in the smallest average lateness.
- Identify which sequence strategy results in the smallest average tardiness.
**Select the appropriate sequencing strategies with the smallest averages for each performance measure:**
- The [Select] has the smallest average flow time.
- The [Select] has the smallest average lateness.
- The [Select] has the smallest average tardiness.
Use these strategies to optimize job sequencing and improve performance outcomes in various operational settings.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F397f2041-1212-4097-b8a0-c62cdf27e29e%2F96e5cfeb-c21c-4af2-9fd4-51ad4c408c02%2F8hgo6l_processed.png&w=3840&q=75)
