Please solve all the points because if I separate them it will be hard to solve. and I will rate you WELL.

Exam 2 project management and forecasting problems. NOTE: you do not need to write your answers on a copy of this document. You can use plain paper. Use the following information to answer the project management questions 1-6. Your submission must include complete precedence diagrams showing all four dates for each activity. A company must perform a maintenance service project consisting of seven activities. The activities, the predecessors, and respective time estimates are as follows. + Immediate Crashing cost Activity Designation Predecessor Time in Weeks $ per week Break down both machines A None 3 6000 Clean machine 1 B 3 3000 Clean machine 2 A 3 1000 Re-set machine 1 D B 4 2000 Re-set machine 2 E 2 1000 Re-calibrate both machines F D and E 1 Not available Final test both machines G F 2 6000 . . . Earliest Start Time (ES)=Latest EF for all immediate predecessors Earliest Finish Time (EF)= ES + activity's duration Latest Start Time (LS)=LF - activity's duration Latest Finish Time (LF)= Earliest LS for all immediate successors Slack = amount of allowable delay in an activity= Equal to LS-ES or LF - EF for an activity . Use the following space to sketch your diagram, use extra sheets if necessary. Be sure to show all four times for each activity. (If you do not do this, and you show/select the wrong answer, there will be no basis for awarding partial credit.) 1. Which of the following is the critical path? a. A, B, D, F, G b. A, C, E, F, G A, C, B, F, E d. A, D, E, F, G e. None of the above What is the duration of the critical path? 2. a. b. C. d. e. 12 13 14 10 11 3. Which of the following activities has slack? a A b. B C. E d. F e. G 4. If it is decided to use all of the available slack in the activity that you selected in #3, which of the following activities would still have available slack? a. A b. B C. C d. F e none 5. It is desired to reduce the duration of this project by one week. All activities can each be crashed by one week and only one week); no activity can be crashed to zero (0). Reducing which activity by one week provides the least cost way of reducing the project duration by one week? a. A b. B ca d. D e. E 6. What is the lowest possible total cost to reduce this project by a total of three weeks? Remember that each activity can only be crashed by one week; no activity can be crashed to zero (0). (Note: your answer to 5 is the first week to be crashed; you need to select two additional activities to each be crashed by one week and then calculate the total cost for all three weeks. Clearly write-in which two additional activities you are crashing.) a $9000 b. $10000 C. $11000 d. $12000 e. $13000 Forecasting Problem Set The following formulas and data are for solving the problems in this part of the exam. The needed forecasting formulas are: FEER + a( A.-F..); or where "F" is the average (non-seasonal- F = a A+ (1-c)F-1 exponential smoothedrolling moving average) forecast where "A" is the seasonally adjusted demand (actual seasonal demand adjusted for seasonality) where "t-1" is the last completed time period and "t" is the time period we are in or just entering FE = ( AF) where "FE" is the forecast error for time period "t". ASA/SFAC where "SALI" is the seasonal (actualunadjusted) demand where "SFACI" is the seasonality factor for the time period in which the actual demand occurred SF with = E. (SFAC) where "SF manch" is the seasonal forecast for any future month asked for. where SFAConch is the seasonality factor for the future month asked for multiplied times the most recently calculated F). The average monthly forecast (that can also be referred to as non-seasonal, exponentially smoothed, or rolling moving average forecast) at the start of November (F) is 1070 units. Alpha (a) equals 0.25 Seasonality factors: Oct. 0.60 (SFAC) Nov.0.80 Dec. 1.85 Jan. 1.25 Feb. 0.95 Use the spaces between the questions to calculate your answers. CIRCLE the answer to each question to avoid any misunderstanding. If submitting using plain paper, write the question number and then show your calculations and answer for the question. 1. At this point in time (the beginning of November), what is the seasonal forecast for November? 2. It is now the beginning of December. Actual seasonal November demand came in at 900. Calculate the revised average forecast. 3. Continuing from question 2: a. what is the forecast error (FE) from November? b. If the running sum of algebraic forecast errors at the end of October was: (14)=-105, what is this sum as of the end of November? 4. Continuing from question 2, as of the beginning of December, what is the seasonal forecast for January? 5. Continuing from question 2, it is now the beginning of January. Actual seasonal December demand came in at 1800. Calculate the revised average forecast. 6. Continuing from question 5, as of the beginning of January, what is the seasonal forecast for January? 7. Continuing from question 5, it is now the beginning of February. Actual seasonal January demand came in at 1200. Calculate the revised average forecast. 8. Continuing from question 7, as of the beginning of February, what is the seasonal forecast for February? EXTRA CREDIT (parts a and b together are worth one question) The current calculation of the MAD was started at the end of February last year and continues into this year. (In other words, at the end of last February, n=1.) As of the end of December: 11 |FE, MAD= n=11; E|FE| 2255 n a. What is the value of MAD as of the end of December? b. Given this January's actual demand (question 7), what is the new value of MAD? Exam 2 project management and forecasting problems.
