A project manager is faced with the following activities and times associated with a building construction for a cancer research facility. Each activity can be crashed at most by 2 weeks. The cost associated with each week time reduction is given below. (note: The 1st crash and 2nd crash costs are associated with the first and second time that a specific activity is crashed. So, if you crash Activity A once, the cost is $9,000, if you have to crash Activity A a second time, the cost is $9,500) Crash Costs
Activity Immediate Predecessor Normal Time (weeks) 1st crash 2nd crash

A 3 $9,000 $9,500
B A 6 $3,500 $6,000
C А 7 $4,000 $5,000

Consumers who participate in the sharing economy seem willing to interact with total strangers. despite safety and privacy concerns, what do you think is the long-term outlook for this change in the way we think about interacting with people whom we don't know? how can businesses to diminish worries some people may have about these practices?

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
