Concept explainers
a)
To determine: Thesequence of jobs that are based on decision rule First Come First Served (FCFS).
Introduction: First Come First Served is the
b)
To determine: The sequence of jobs based on decision rule Shortest Processing Time (SPT).
Introduction: Shortest Processing Tine is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the shortest duration would be served first. Then, the process would go on from the shortest to largest duration.
c)
To determine: The sequence of jobs based on decision rule Longest Processing Time (LPT).
Introduction: Largest Processing Tine is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the largest duration would be served first. Then, the process would go on from the largest to shortest duration.
d)
To determine: The sequence of jobs based on decision rule Earliest Due Date (EDD).
Introduction: Earliest Due Date is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the earliest due date would be served first. Then, the process would go on from the earliest due date to latest due date.
e)
To determine: The sequence of jobs based on critical ratio.
Introduction: Critical ratio is kind of scheduling rule that helps to identify that, the task or job is on the correct track. It would help to identify if the task is behind or ahead of the schedule.

- Question 2: A manager wants to assign tasks to workstations as efficiently as possible and achieve an hourly output of 28 units. Assume the shop works a 56-minute hour. Assign the tasks shown in the accompanying precedence diagram (times are in minutes) to workstations using the following rules: (SEE PHOTO) a. What is Cycle time? (Round your answer to 1 decimal place.) In order of most following tasks. Tiebreaker: greatest positional weight. (Use your rounded cycle time. Enter your tasks in the order they were assigned at each station as a letter between a and h in lowercase with no other text or symbols. Round your numerical answers to 1 decimal place.) What is Efficiency? (Use your rounded cycle time in the denominator of your efficiency calculation. Round your answer to 1 decimal place.) b. In order of greatest positional weight. Tiebreaker: most following tasks. (Use your rounded cycle time.

A unit needs to be processed at either Machine A or Machine B for Station 1 (parallel lines, both lines doing the exact same thing). The unit is then processed at Stations 2 and 3 before leaving the work cell. What is the process time of this system measured in minutes/unit?arrow_forward

All dates are according to shop calendar days. Today on the planning cal- endar is day 130, and none of the jobs have been started or sched- uled. Which rule is best? Pxarrow_forward
- Question 1 Four floral arranging jobs are to be carried out across three stations: A (Arrange), B (Bag), C (crop) shown. The station sequences and job times in minutes are shown below, along with the due dates for each job. Using an "earliest due date" job dispatching priority rule, which, if any, of the jobs in will be late? Tip: create a Gantt chart schedule before answering Questions 4 & 5. a. Jobs 2 & 3 b. Jobs 3 & 4 c. Job 3 d. Job 4 e. None of the jobs will be latearrow_forwardQuestion Three Processing times (including setup times), and due dates for five jobs waiting to be processed at a work center are given in the following table. By Using the SPT rule determine the following: The sequence of jobs The average flow time The average job tardiness The average number of jobs at the work center Job Processing Time (hours) Hour Due A 17 15 B 10 25 C 5 20 D 7 32 E 11 38arrow_forwardQuestion 1 Rock View Restaurant is a new fast food restaurant chain. The Operations Manager has divided its normal drive-through service process into the following tasks: Tasks Description Task Time Predecessors (In Seconds) A Take order 25 None В Receive payment 20 A C Gather drinks 35 A D Gather food 32 А Put food etc. in bag Give food to E 25 C.D F 10 В.Е customer Currently, Rock View Restaurant has a single window with one person who takes the order, gather the food, collects the money and gives the food to the customer. This takes an average of 147 seconds per customer so only 25.5 cars can be served. Rock View Restaurant wants to increase its drive-through capacity to 60 cars per hour by forming a multi-window line. i. Draw the precedence diagram to represent the process at Rock View Restaurant. ii. Calculate the cycle time in seconds. iii. Calculate the minimum number of windows that Rock View Restaurant will need to serve 60 cars per hour.arrow_forward
