.The gentleman farmer and surrealist aficionado commissioned a mural on barn that was an homage to Salvador Dalí’s Persistence of Memory with a few farm animals included. The project would require the services of a senior muralist, a junior muralist, and a gofer. The senior muralist has an annual salary of $120,000, the junior muralist draws an annual salary of $75,000, and the gofer makes $30,000 per year. It is anticipated that the project will require 25 hours of senior muralist time, 40 hours of junior muralist time, and 60 hours of gofer time. Overhead charges vary by position; the gofer has a lower overhead rate (30%) than the two muralist positions (50%). Use 2080 hours as an estimate for the number of hours in a year and a 15% factor for personal time. What is the total direct labor cost for the project?
2.Three workers complete a full 8-hour day finishing concrete for a terrace. All three workers are paid $12 an hour and the job bills to the customer for $450. What are the total direct labor costs?
3.A systems analyst is paid at the rate of $50/hour and will be needed for 40 hours. Her employer uses an overhead multiplier of 60% and does not factor in personal time. Her total direct labor cost should be billed at:
4.An activity with a learning rate of 0.85 takes 25 hours for the first iteration. How long will it take to complete this task for the 15th time?
5.An activity has an optimistic time estimate of 25 days, a most likely estimate of 29 days, and a pessimistic estimate of 34 days. What is the expected duration of the activity?
6.An activity has an optimistic time estimate of 12 days, a most likely estimate of 16 days, and a pessimistic estimate of 22 days. What is the expected standard deviation of the activity?
7.A gentleman farmer maniacally works on academic projects to raise funds for his true passion, farming. He has identified seven tasks and developed three time estimates (all in days) of the next big project on the farm, replacing the fence at the comedy pasture. Tasks, precedence requirements, and time estimates are shown in the table. What is the expected completion time of the project?
8.Use the Gantt chart and the activity list to determine when resource 5 is free.
9.Use the Gantt chart and activity list to determine which resource is used the least.
10.A project has the activity duration and cost information indicated in the table where all times are in weeks. There is a penalty of $6,000 per week for every week the project extends beyond 25 weeks. What is the lowest total cost duration for completing this project?
11.A project consists of eleven activities (all times are given in days) and has worker requirements as indicated in the table. Assume that all six workers employed by this organization are generalists and are able to work on any of the tasks. What is the fastest the project can be completed?
