Consider the following network for conducting a $2$week $(10$ working days$)$ computer training class:

Schematic illustration of a network for conducting a $2-$week $(10$working days$)$ computer training class.

Construct a schedule showing:

ESs for all activities

LSs for all activities

Slacks for all activities

Critical path

Given the following

Activity Crash Time $($days$)$ Crashed Cost $($total$)$ Normal Time $($days$)$ Normal Cost

A: Obtain instructor $4$ $$8007$ $$500$

B: Locate a room $23503200$

C: Check costs $49006500$

D: Room open? $15003200$

E: Schedule class $15502300$

$$3100$

Find the crash cost per day.

Which activities should be crashed to meet a project deadline of $10$ days with a minimum cost? Assume partial crashing.

Find the new cost.

Is partial crashing an appropriate assumption in this kind of project?
