question 59

Multiple Choice

A project is represented by the activity durations (estimated at 90% likelihood of completion) and precedence requirements shown in the table.What is the overall duration of this project if it is managed using critical chain methodology? $$\begin{array} { | l | l | l | l | l | l | } \hline \text { Activity } & \text { Predecessor } & \text { Ieength } & \text { Activity } & \text { Predecesser } & \text { Ieength } \\\hline \text { A } & - - & 20 & \mathrm { D } & \mathrm { B } & 16 \\\hline \mathrm { B } & \text { A } & 20 & \mathrm { E } & \mathrm { C } & 8 \\\hline \mathrm { C } & \text { A } & 10 & \mathrm {~F} & \mathrm { D } , \mathrm { E } & 8 \\\hline\end{array}$$

Extinction

In psychology, the gradual weakening of a conditioned response when the conditioned stimulus is presented without the unconditioned stimulus.

Conditioned Reinforcer

A stimulus that has become reinforcing through its association with a primary reinforcer.

Variable-Ratio Reinforcement Schedule

A reinforcement strategy where a response is reinforced after an unpredictable number of responses, which typically leads to high and steady response rates.
