A local toy maker uses a manufacturing line running eight hours a day that produces a toy which needs 7 tasks in total. The regular requirements are 100 toys. Task times are 2.73,2.01,2.13,2.0.2.11,2.71 and A,B,C,D,E,F and G, respectively, 2.95 minutes. However, there are precedent laws because of the essence of the substance that must be followed. This type of task has no predecessors; task B needs the completion of task A. To begin task C and task D, each task requires the completion of task B. Mission must be done until task E is defined. Goal F has to be done with Task D and Task Finally, task G will only start until task Fis has been completed. Since we extend the remaining job rule to balance the production line with the linkage broken in the longest working period, check circle is the task allocated to the THIRD station
(Note: Task N is a dummy task. It must be included in the relationships, but its duration is 0. Be sure its duration is set to 0) Please see attached charts and diagram. Assign the following resources to the tasks. All resources will be full time. (Set the leveling to manual first). Task Resource Cost / Day A R1 200 B R2 300 C R3 300 D R4 300 E R2 300 F R4 300 G R1 200 H R5 200 I R6 400 J R5 200 K R1 200 L R3 300 M R2 300 N - - 2. Level if necessary. Then determine the new critical path and duration. 3. What is the total cost of the project (Fixed + Resource cost)? How much does the project need in the first, second, and third weeks?

For this assignment you must pick 4 processes – one from each of the knowledge areas listed below. For each process, write a paragraph (or two) that describes the process, explains the key benefit of using the process, and describes a garden in my backyard that would benefit from using the process. Knowledge Areas: • Integration Management • Scope Management • Time Management • Cost Management In lieu of an individual process, you may also choose a group of closely related processes (e.g., define activities and sequence activities). In this case, you must describe both processes and both key benefits, but you can describe a single hypothetical project situation. Keep in mind that a group of related processes only counts as one process for the purposes of this assignment
An Insurance Company is introducing two new product lines: special risk insuranceand mortgages. The expected profit is $5 per unit on special risk insurance and $2 per unit onmortgages.
