Assume that orders for suits have been listed in the above table in the order in which they were
received.
A manufacturer is designing a product layout for a new product production. It plans to use a production line for 8 hours per day in order to meet forecasted
demand of 150 units per day. The product requires 7 tasks in total. These tasks are namely, A, B, C, D, E, F, and Grespectively. Task A does not have any
predecessor to start. To start Task B, it requires Task A to be completed. Starting tasks Cneeds, the task B to be completed. Also, starting task D needed
task B to be completed. Task E can only start upon completion of Task C. Whereas starting task F needs the completion of both the tasks D and E. Finally,
starting task G needed, task F to be completed. The processing times for tasks, A, B, C, D, E, F. and G are 2.3, 2.1, 0.9, 1.0, 1.2, 1.8, and 1.5 minutes
respectively. Applying the most remaining tasks rule for balancing the assembly line, with ties broken according to longest task time first, the tasks that will
be assigned to the LAST workstation are

Your team has been assigned to complete 10 client projects over the next two months. These
projects and their processing times (time taken to complete a project once started, in days) are
described in the table below. In addition, each project has a due-date that has been set by your
internal marketing team so that the customers will be delighted with your service if you complete the
project by the due-date. However, your team has only enough resources to pursue exactly one
project at any given time. Once started, a project is worked through its completion and is not
interrupted. As a result of the sequence in which you choose to handle projects, each project will
either be on time, or late if it is completed past the due date. If a project is late, the amount of time
by which it misses its due-date is called its tardiness. The objective is to pick the sequence in which to
complete the projects so as to minimize the total tardiness in the schedule.
What is the minimum total tardiness…

- Mr. Elf owns a show store. Currently, he has 10 pairs of shoes that require resoling and polishing. He has a machine that can resole one pair of shoes at a time, and the time required for the operation varies with the type and condition of the shoe and the type of sole that is used. Shoes are polished on a machine dedicated to this purpose as well, and polishing is always done after resoling. His assistant generally does the polishing while Mr. Elf does the resoling.

The sequence of tasks may have them put in mutual relationships according to 4 dependencies: start-to-start, finish-to-finish, start-to-finish, and finish-to-start. The latter is the most common: one task gets finished so the next starts. The next to last is the most uncommon: the next task won't finish before the first one starts. Look up definitions of all of those dependencies and bring up one example for any two of the following dependencies: start-to-start, finish-to-finish, start-to-finish. Discuss how your example is appropriate for the selected dependency. ps. This Questiong is about ''project Management" please, and thank you.arrow_forward

Some of the jobs can begin immediately but other jobs can only begin after others are completed. For example, grading can begin immediately but laying a foundation must be delayed until the grading is completed. The data below are for a project which includes ten jobs; the time it takes to complete each job is known and the set of jobs which must be completed before each job can begin is known. Your objective is to find a schedule (i.e. beginning times and ending times) for all of the jobs such that no jobs begins before any of its predecessors are completed and the time when all jobs are finished is minimized.

Assume that all time till the last class begins can be spent on completing assignments but each assignment should be done till the time of the class on the same subject. (Mike can prepare assignments for the next classes during previous classes.) Use the Excel Sequencing template to determine how he should schedule the work. Use minus sign to enter negative lateness values, if any. Enter the half an hour value as 0.5, e.g., 3:30 p.m. should be entered as 15.5. If your answer is zero, enter "0".
