You are in charge of a project at the local community center. The center needs to remodel one ofthe rooms in time for the start of a new program. Delays in the project mean that the center mustrent other space at a nearby church at additional cost. Time and cost data for your project arecontained in below table. Your interest is in minimizing the cost of the project to the communitycenter.Using the normal times for each activity, what is the earliest date you can complete the project?Suppose the variable overhead costs are $50 per day for your project. Also, suppose that thecenter must pay $40 per day for a temporary room on day 15 or beyond. Find the minimum-costproject schedule using below format.The AON diagram for the community center project is below. Crash 4 times and find total cost.
Using your results from Problem 6,(a) Calculate the probability that the project will be completedin 38 weeks.(b) Calculate the probability that the project will be completedin 42 weeks
Identify the term being described for each of the following: (a). A sequence of activities in a project. (b). The longest time sequence of activities in a project. (c). Used when two activities have the same starting and finishing points. (d). The difference in time length of any path and the critical path. (e). The statistical distribution used to describe variability of an activity time. (f). The statistical distribution used to describe path variability. (g). Shortening an activity by allocating additional resources.
A Company wants to execute a project within 95 weeks. This project includes 10 activities (labeled A, B, ..., J), where their precedence relationships are shown in the following table: Predecessor Normal Crash Normal Cost Crash Cost Activity Activity Time(weeks) Time(weeks) (in million S) (in million S) A 32 28 160 180 В 28 25 125 146 C A 36 31 170 210 D B 16 13 60 72 E 32 27 135 160 B 54 47 215 257 D 17 15 90 96 H E,G 20 17 120 132 E,G 34 30 190 226 F.C 18 16 80 84 a) Draw the project network according to the previous table. (b)Find all possible paths and the corresponding lengths to finish the project. (c) Which is the critical path and what is its length? (d) Determine the least expensive way to crash activities to reduce overall duration to 95 weeks using Marginal cost analysis.
In the space provided below create the network diagram that shows the relationship (logic) of project activities shown below and then number each event. 1. In a given project activities "A, B and C are initial activities that may begin at the same time 2. -----"D" cannot begin until "A" is complete. 3. ----- "B" must be complete before E can begin. 4. ----- "F" cannot start until "C" is finished. 5. ----- "G" cannot begin until "B" is finished. 6. ----- "G" and "D" must be done before "H" can begin. 7. ----- "I" cannot begin until "B" is finished. 8. ----- "J" can begin only after "F" and "I" are complete. 9. ----- Once "E" is complete, "K" can begin. 10. ---- The project will be finished when "H" "J" and "K" are complete.
Suppose that you are assigned to a construction project which is planned to be build as early as possible. As a planning engineer you have to find the right sequence of activities in order to complete the project on time. Use Gantt (Bar) Chart and calculate total duration and determine the critical path of the project. Immediate Estimated Activity Predecessors Duration 2 weeks 4 weeks 10 weeks A 6 weeks 4 weeks S weeks 7 weeks 9 weeks 7 weeks 8 weeks G E, G F, 1 4 weeks 5 weeks 2 weeks 6 weeks K M K, L Immediate Predecessor (Finish to Start) Construct Gantt Chart of the project.

Starting the backward pass with activity I, the latest finish time is LF = 26 and that the activity time is t = 2. And the latest start time for activity I is LS = 24. What is the earliest start (ES) and earliest finish (EF) times?

In the project considered below, activity crashing can take place over a wide range of reduction times. The cost per day of reduction is given: Activity Immediate Normal Time Cost/day Lower Time Predecessor (days) Limit A None 3 450 1 B None 4 300 2 A 3 200 D E 100 E A,B 500 1 F C.D 4 600 3 For example, activity C can be crashed from its normal time of 3 days down to as little as 1 day or anywhere in between; the cost per day to crash C is 200. a) Draw a network diagram for this project. What is the critical path? How long will the project take, if no crashing takes place? b) Determine the least cost way to crash activities in order to complete the project in 11 days; in 10 days; in 9 days; in 8 days. c) Suppose the due date for the project is 5 days and a penalty of $500 a day is assessed for each day late. What is the optimal number of days to crash the project? Why?
