Given the following project (all times are in days): please refer the pic  All activities, except for activity b , may be partially crashed.(i.e. partial crashing for activity b only, is not allowed.) 2) If the project indirect cost is $89/day, what is the optimal completion time and the corresponding total cost?

Using the information given and the project completiontime calculated in Problem 9(a), reduce the completion time ofthe project by 3 weeks in the most economical way.

A) What is the variance activity B? 2 decimal places B) What is the variance of activity F? 2 decimal places C) what is the probability the project can be completed? 4 decimals places only D) what is the probability the project will be 3 weeks late from the expected completion time ? 4 decimal places only.

Three recent college graduates have formed a partnership and have opened an advertising firm.Their first project consists of activities listed in the following table.a. Draw the precedence diagram.b. What is the probability that the project can be completed in 24 days or less? In 21 days or less?c. Suppose it is now the end of the seventh day and that activities A and B have been completedwhile activity D is 50 percent completed. Time estimates for the completion of activity D are5, 6, and 7. Activities C and H are ready to begin.

The partners have decided that shortening the project by two days would be beneficial, as longas it doesn’t cost more than about $20,000. They have estimated the daily crashing costs for…

Given the following project (all times are in days): refer the pic please  All activities, except for activity b , may be partially crashed.(i.e. partial crashing for activity b only, is not allowed.) 1. Draw the network and find the critical path, time, and total cost for an all-normal level of project activity.

Please find the questions Note : The first question is in detail the question of the (LSD, LFD)

The following payoff table shows profit for a decision analysis problem with two decision alternatives and three states of nature. Decision Alternative If S1 d₁ d₂ States of Nature then ? $1 240 90 90 15 The probabilities for the states of nature are P(S₁) = 0.65, P(s₂) = 0.15, and P(s3) = 0.20. (a) What is the optimal decision strategy if perfect information were available? ; If S₂ then ? 90 65 ; If S3 then ? (b) What is the expected value for the decision strategy developed in part (a)? î (c) Using the expected value approach, what is the recommended decision without perfect information? What is its expected value? The recommended decision without perfect information is ? EV = (d) What is the expected value of perfect information? EVPI = î

9.  A project has the following activities, with specified precedents, expected durations (in days), and crash cost/day. Each activity can be crashed to a minimum duration of 1 day. (This is the same network as a previous problem.) What is the minimum total cost to shorten the project by 2 days? Round your answers to 2 decimals.   Activity Precedent Duration Crash cost/day A - 3 $350 B A 3.8 $250 C A 6 $400 D B 6 $150 E B 4.1 $200 F C 4 $275 G D 6.2 $500 H E 8 $300       Answer:

Draw a network representation of the project (nodes = activities, arrows = precedence constraints). Provide early start/early finish as well as late start/late finish times for all activities. What is the duration of the project, and which tasks are on the critical path?
