Answer

Question 44

Explanation:

Step1: Apply Johnson's rule

Johnson's rule for two - workstation sequencing aims to minimize the makespan. First, find the minimum processing time among all jobs on both workstations. The minimum time is 8 (Job B on Workstation #2). Job B is placed first in the sequence.

Step2: Remove Job B

After placing Job B, remove it from consideration. Now, the new minimum is 11 (Jobs E and F on Workstation #1). Since it is on Workstation #1, they are placed next in the sequence (either E then F or F then E). Let's take E - F.

Step3: Consider remaining jobs

The remaining jobs are A, C, D. The next minimum is 20 (Job B on Workstation #1). After considering all jobs and sequencing them, assume the sequence is B - E - F - D - C - A.

Step4: Calculate makespan

Calculate the cumulative time at each step for Workstation #1 and Workstation #2. For Workstation #1: 20+11 + 11+30+25+50=147 For Workstation #2: We need to consider the waiting time. After Workstation #1 finishes a job, Workstation #2 starts. The makespan calculation takes into account the time when Workstation #2 is idle or working. The makespan is 20 + 11+11+30 + 25+50+(50 - 25)=201 (the last term (50 - 25) is to account for the time Workstation #2 has to wait for Workstation #1 to finish Job A).

Answer:

more than 200 but less than or equal to 250 minutes.

Question 45

Brief Explanations:

Triage nurses deciding the order of treating emergency patients is about determining the sequence of tasks. Sequencing in operations management is about arranging the order of activities or tasks. Appointing is about assigning positions, statistical forecasting is about predicting using statistical methods, and demand planning is about estimating future demand.

Answer:

sequencing
