Suppose that a task in a project has the following time estimates: to=optimistic completion time=10 weeks tm=most likely completion time=17 weeks tp=pessimistic completion time=19 weeks Compute the expected task variance. The task expected task variance is _____ weeks. (Enter your response rounded to two decimal places.)
Consider a project with seven tasks. Three tasks – tasks 3, 4, and 5 – require a specific resource for completion; all needed resources must be available at the site before a task can be started. Task Duration Predecessor (s) Units of Value of Resource Completed Task Needed 3 3 10 $4000 3 1 10 S3000 3 12 $5000 1 4 7 2, 5,6 Each resource unit cost $100; no quantity discounts are available. In addition, it costs $2 per unit per time period to hold this resource in stock, and it costs $45 just to place an order for materials (independent of the number of units ordered). When should each task in the project be started and when and how many resources should be ordered to minimize total project costs? 1. 1, en en 1. 2. en

The product development group at “Griffin” Company has already worked on new computer software products that has potential to know a large market share. Via an outside source, London Management has learned that a competitor is working to bring a similar product to market. As a result, London's top management increased its pressure on the product development group. Group leaders have turned to CPM / PERT as an aid to scheduling remaining activities before new products can be brought to market. The estimated time of activity in a day is as follows a.Create the the network if it is accelerated according to the schedule above b.Find the cost and the duration c.Determine the path and critical activities
