Twelve tasks, with times and precedence requirements as shown in the following table, are tobe assigned to workstations using a cycle time of 1.5 minutes. Two heuristic rules will be tried:(1) greatest positional weight, and (2) most following tasks.In each case, the tiebreaker will be shortest processing time.

Assign tasks to stations under each of the two rules.c. Compute the percentage of idle time for each rule

In a job shop, there are four machines: a miller, a planer, a drill, and a packager. The natural process times (in minutes) for each of the machines are: 8, 8, 10, and 13, respectively. The critical WIP of the system, if the four machines are connected in the order given is:

A local toy manufacturer is using a production line that runs 8 hours per day and produces a toy that requires a total of 7 tasks to be performed. The daily demand is 100 toys. Times of the tasks are 2.73, 2.01, 2.13, 2.0, 2.61,2.71, and 2.95 minutes for A, B, C, D, E, F, and G, respectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task A does not need any predecessors; task B requires task A to be completed. To start task C and task D, each require task B to be completed. Task C must be completed prior to stating task E. Task F needs both task D and task E to be completed. Finally, task G can start only once task F is completed.Given we apply the most remaining tasks rule for balancing the assembly line, with ties broken according to longest task time first, What will the estimated idle time in minutes for FOURTH workstation?

Three jobs are ready for processing at time zero through a workstation. The details regarding the processing time and the due date of completion is provided in the following table.   Job         Processing Time (days)              Due Date   A                            2                                                 8   B                            6                                             6   C                           5                                            13     Using the earliest due date (EDD) rule, the average tardiness of the five jobs is:

Given the data below, using the SPT heuristic sequencing rule, determine the completion date and tardiness for each job as well as the average completion time and average tardiness for all four jobs. Which of the following statements is true? Job Processing time (days) Due date (in days) A 10 10 B 5 8 C 15 25 D 8 15 a.Jobs B and D will have no tardiness b.The tardiness for Job A is 12 days c.The average tardiness is 19.75 d.The average completion time is 6.5

Suppose that a task in a project has the following time​ estimates:   to=optimistic completion time=9 weeks tm=most likely completion time=17 weeks tp=pessimistic completion time=21 weeks   Compute the expected task completion time.   The expected task completion time is _________  weeks. ​(Enter your response rounded to one decimal​ place.)

At the campus copy shop, six jobs have a rrived in the order shown (A, B, C, D, E, and F) at the beginning of the day (today, which is a workday). All of the jobs are due at varioustimes today. Your task is to evaluate four common sequencing rules.                                                      a) Sequence the jobs according to the following decision rules:FCFS, EDD, SPT, and LPT.b) For the FCFS sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system.c) For the EDD sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system.d) For the SPT sequence, compute the average completion (flow) time, average lateness, and average number of jobs in the system.                                                                                                                  e) For the LPT sequence, compute the average completion (flow)time, average lateness, and average number of jobs…
