You have prepared the following schedule for a project in which the key resources is a tractor. There are three tractors available to the project. Activities A and D require one tractor to complete while activities B, C, E and F require 2 tractors.Develop a resource-constrained schedule in the loading chart that follows. Use the parallel method and heuristics given. Be sure to update each period as the computer would do. Record the early start (ES), late finish (LF) and slack (SL) for the new schedule
Activities K, M and S immediately follow activity H, and their latest start times are 14, 18, and 1 The latest finish time for activity H
A. is 11.
B. is 14.
C.is 18
D.annot be determined.

Regarding section D with assigning the workstations:
How would Task F go first if it could not be completed with Task D? Usint LOT. regardless of the time each took, doesn't one still have to bare in mind the predecessors? I would assume Tasks A and B would be Workstation 1, considering that 45 plus 20 seconds is less than the cycle time and factoring in the fact that C only requires A to be completed, hence why the workstation should start at A followed by C.

- Amanufacturer 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 dayThe product requires 7 tasks in total. These tasks are namely, ABC, DE, Fand GrespectivelyTask A does not have any predecessor to start. To start Task B, it requires Task A to be completedStarting tasks C needs, 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 and E. Finally, starting task G needed, task F to be completed. The processing times for tasks, AB 3, C, D, E, F , and Gare are2.4,2.2,0.9, . 10.12. 1.8. are 1.5 minutes respectively.

- Using Johnson's rule for 2-machine scheduling, the sequence is: Scheduled Order Job 1 ▼ B C E F A D Part 2 2 ▼ F C A D B E Part 3 3 ▼ A B D F C E Part 4 4 ▼ E D C B F A Part 5 5 ▼ F C D A E B Part 6 6 ▼ D C F B E A Part 7 For the schedule developed using Johnson's rule, the total length of time taken to complete the six jobs (including the 2nd operation) = enter your response here hours (enter your response as a whole number). ... Question content area right Part 1 Six jobs are to be processed through a two-step operation. The first operation involves sanding, and the second involves painting. Processing times are as follows: Job Operation 1 (hours) Operation 2 (hours) A 4 8 B 10 5 C 3 11 D…arrow_forward. With activities B and C as immediate predecessors, the earliest start time for activity H must be equal to the largest of the earliest finish times for activities B and C. Thus, with EF = 6 for activity B and EF = 9 for activity C, 9 is the earliest start time for activity H (ES = 9). And with an activity time of 12 as shown in the node for activity H, what is the earliest finish time?arrow_forwardFor the activity on arrow network information given below (activity durations are givenin the table under part b): a. Compute the earliest event occurrence time (TEj), the latest allowable eventoccurrence time (TLj), and the event slack (ESj) for all nodes/events. b. Compute the four schedule dates (ESDij, EFDij, LSDij, LFDij) and the floats(TFij, FFij) for all activities.arrow_forward
