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…

How Can You Get to a Backlog of over 100 Projects? There are never enough resources to get everything done." Backlogs build over time. Sacred cow projects get included in the selection system. Projects proposed from people who have left the airline stil reside in the project portfolio. Non-value-added projects somehow make their way into the project portfolio. Soon the queue gets longer. With everyone in IT working on too many projects concurrently, project completion and productivity are slow. Which Projects Remain? To cut the number of projects, the steering committee used a weighting scheme that reflected the airline's priorities, which were: fly safe, generate revenue, reduce costs, and customer service. The weighting scheme easily weeded out the fluff. Coady noted that "by the time you get to the 20s the margin of differentiation gets narrower and narrower." Of the remaining projects, project sponsors had to have solid justification why their project is important. Reduction of the…
A company is setting up an assembly line to produce 90 units per hour. The table below identifies the work elements, times, and immediate predecessors. Work Element Time (Sec.) Immediate Predecessor(s) A 25 - B 18 A C 20 A D 5 B, C E 12 C F 8 E G 16 D, F H 12 G Use one of the heuristic decision rules described in Table below to balance the assembly line so that it will produce 90 units per hour. Clearly state the decision rule you use and complete the below table using the selected rule. Decision Rule Logic Longest work element Picking the candidate with the longest time to complete is an effort to fit in the most difficult elements first, leaving the ones with short times to “fill out” the station. Shortest work element This rule is the opposite of the longest work element rule because it gives preference in workstation assignments to those work elements that are quicker. It can be tried…
