$10\mathrm{.}2$ Examine the network schedule with its activities, their durations, and initial

cost plus extra cost for acceleration in the table. Draw its network diagram,

determine the critical path, perform a time$$cost trade$-$off analysis to minimize the

total project duration and accelerated cost, and record your

steps.
