Can i get help with the question below please and thank you 16) This could be a rover, probe/satellite, manned mission, telescope, etc. This mission must be accomplished using technology that is available today (no Warp or Epstein drives) and must be accomplished within your lifetime. Your mission will not be a copy of a real mission. Constraints: ▪ Answer using the underlined subheadings at each point below (Mission Objective, Target, Instrumentation), marks will be deducted for poorly organized answers. ▪ You target must be reachable by whatever you are sending within a human lifetime (~75 years), it would be nice to visit Gliese 581c, but it is 20 light years from Earth so for now it is unreachable. What this means is that you are constrained to our solar system except for telescopes that peer into the universe or a probe getting to interstellar space. ▪ If your mission includes sending humans, then we need to estimate a reasonable limit on how far we can send humans. For our…
Kirti and the team want to ascertain the expected activity time and the variance of activity zeta of the company where optimistic time for that is 45 days , pessimistic time is 155 days and the most likely time is 60 days ?
Consider the office renovation project data in the following table. A "zero" time estimate means that the activity could take a very small amount of time and should be treated as a numeric zero in the analysis. a. Based on the critical path, find the probability of completing the office renovation project by 39 days. Refer to the standard normal table (Make sure to round all intermediate calculations for te and variance to two decimal places.) The probability is
Follow up to previous question: 3) A company decides to plan a project, with activities, precedences and random duration statistics given in the following table: Activity Immediate Predecessors Duration Minimum (weeks) Duration Mode (weeks) Duration Maximum (weeks) A none 2 5 9 B A 1 6 8 C A 3 5 12 D B 2 4 12 E B, C 4 6 8 F B 6 7 8 G D, E 1 2 6 H F, G 4 6 16 Questions: 1) What method should be used? Compute the mean and variances for each activity and add them to the table above. 2)Draw the project network and label the arcs with the activity name. 3) Assuming that the critical path is AàBàP1àEàGàH, compute the probability that this path duration is between 28 weeks and 32 weeks. 4) Assuming that the critical path is AàBàP1àEàGàH, compute the number of weeks within which the project will be completed with probability 0.95.
