Chapter 6, Problem 10E
K. Nelson, project manager of Print Software. Inc., wants you to prepare a project network; compute the early, late, and slack activity times; determine the planned project duration; and identify the critical path. His assistant has collected the following information for the Color Printer Drivers Software Project:

Draw the network diagram.
Calculate the expected duration and variance of each activity.
Calculate the expected duration and variance of the critical path.
Calculate the probability that the project will be completed in less than 28 weeks.
The managers at AllBirds have operations in multiple countries, which operate on different financial management systems. This has been increasingly challenging for the company, so the Justin is looking to consolidate and integrate the financial management across all locations into a single software system that can operate across the national boundaries.
This is a new, complicated and lengthy project, so Justin has identified a set of activity categories that will need to be carefully managed, as noted in the table.
Draw the project network, and compute the expected time and variance for each activity.Â
Develop an activity schedule for this project, compute activity slack time and identify critical path.
A project consists of the activities in the following list. Times are given in weeks.

- The activities of a project, their normal and shortest completion times in days, their respective completion costs in euros, and the constraints on their execution sequence are presented in the table below. Questions: A) To build the network that graphically illustrates the project. B) To find the shortest and slowest start and end times. C) Find the critical path and calculate the total cost. D) To consider the case of reducing the total duration of the project by 1 day at the lowest possible cost.arrow_forwardThe Industrial and Systems Engineering Department at Sun University is moving from its old building to a new building. The move must be completed within the 14-day period between semesters. A list of tasks (activities) has been prepared. The activities and precedence requirements are presented in the table below.
