A project consists of six consecutive tasks that have average duration and worst-case duration estimates (in days)as shown in the table.Use Newbold's method to determine the aggregated two sigma buffer for this project. \[\begin{array} { | l | l | l | } \hline \text { Activity } & \text { Average } & \text { Worst-Case } \\ \hline \mathbf { A } & 14 & 21 \\ \hline \mathrm { B } & 20 & 28 \\ \hline \mathrm { C } & 16 & 22 \\ \hline \mathrm { D } & 8 & 15 \\ \hline \mathrm { E } & 9 & 18 \\ \hline \mathrm { F } & 11 & 18 \\ \hline \end{array}\]

A) 44 days B) 6 days C) 17 days D) 9 days A) 44 days B) 6 days C) 17 days D) 9 days

Use the project information in the table to resolve resource conflicts,identify the critical chain and critical path,and create feeder buffers.A feeder buffer should be placed immediately before: \[\begin{array} { | l | l | l | l | l | l | l | l | } \hline \text { Activity } & \text { Predecessor } & \text { Length } & \text { Resource } & \text { Activity } & \text { Predecessor } & \text { Length } \text { Resource } \\ \hline \mathrm { A } & - & 11 & \mathrm { P } & \mathrm { D } & \mathrm { C } & 13 & \mathrm { P } \\ \hline \mathrm { B } & \mathrm { A } & 7 & \mathrm { M } & \mathrm { E } & - & 12 & \mathrm { X } \\ \hline \mathrm { C } & \mathrm { B } & 8 & \mathrm {~W} & \mathrm {~F} & \mathrm { E } & 14 & \mathrm { M } \\ \hline \end{array}\]

A) Activity B. B) Activity F. C) Activity C. D) Activity A. A) Activity B. B) Activity F. C) Activity C. D) Activity A.

A project is represented by the activity durations (in days,estimated at 90% likelihood of completion)and precedence requirements shown in the table.What is the length of a feeder buffer if this project is managed using critical chain methodology? \[\begin{array} { | l | l | l | l | l | l | } \hline \text { Activity } & \text { Predecessor } & \text { Length } & \text { Activity } & \text { Predecessor } & \text { Length } \\ \hline \text { A } & - & 18 & \text { E } & \text { C, D } & 13 \\ \hline \text { B } & - & 16 & \text { F } & \text { C } & 9 \\ \hline \text { C } & \text { A } & 22 & \text { G } & \text { E, F } & 15 \\ \hline \text { D } & \text { B } & 14 & & & \\ \hline \end{array}\]

A) 4 days B) 3 days C) 2 days D) 1 days A) 4 days B) 3 days C) 2 days D) 1 days

A) A safety margin separating different projects scheduled to use the same resource. B) Extra safety that is applied to a project immediately after the use of the constrained resource. C) A constraint separating different projects that requires a common buffer. D) Extra safety that is applied to a project immediately before the use of the constrained resource.
