Determine True$/$False $($No Explanations needed$)$:

$($i$)$ The CPM method was developed primarily for the construction industry.

$($ii$)$ CPM uses a fixed value for project duration.

$($iii$)$ A Dummy Activity may sometimes have non$-$zero duration.

$($iv$)$ In a CPM arrow network, when two or more arrows begin at the same node, this means

that the work must end at the same time.

$($v$)$ The Forward & Backward Pass algorithms calculate EST and LST$,$ respectively, of

all activities.

$($vi$)$ The Critical Path time is defined as the longest possible path of the network.

$($vii$)$ Backward Pass algorithm assumes the duration of the project as obtained by the

Forward Pass.

$($viii$)$ On the Activity$-$on$-$Arrow network, the nodes represent a point in time.

$($ix$)$ To draw an Activity$-$on$-$Arrow network, Activities IPA are needed.

$($x$)$ Calculation of Duration of a Project $(D_{ij})$ using Average Productivity is usually an

optimistic one.

$($xi$)$ Cash$-$flow Analysis using CPM can be done by EST or LST Schedule

$($xii$)$ Resource Leveling using CPM is usually a trial$-$and$-$error method

$($xiii$)$ For a PERT model if each activity has a $T{e}_e=0,$ then effectively it becomes a CPM

model.

$($xiv$)$ The Expected Time for PERT is a weighted average of three times

$($xv$)$ In the Monte Carlo $($Simulation$)$ Method, Activity Durations are generated by random

numbers.
