Chapter 2 Homework Problem Solutions Chapter 2 Project Management Study Objectives: construct a network diagram for a project determine critical path and expected completion time of a project with deterministic task times (note: some of us also do calculations for probabilistic times‚ but not required) calculate slack times for a particular task know how to “crash” a project down to a certain completion time at the lowest cost (note: just the concept of crashing needs to be discussed and not the

a project deadline of 10 days at minimum cost? [3 points] The diagram shows two paths: ABE and CDE. Based on normal duration estimates‚ ABE will take 12 days to complete and CDE will take 11 days. Therefore the earliest the project can be completed (on critical path ABE) is 12 days. The total project cost based on normal time is: $300 + $250 + $400 + $200 + $300 = $1450 Activity on the critical path that can be accelerated at the lowest cost per day is Activity B @ $50. If Activity

1. Convert the project network to an Activity-on-node (AON) representation. What is the project completion time and critical path for this project ? Critical path is A-B‚ B-D‚ D-E 3. Suppose that activity AD were delayed by 2 weeks (takes 8 weeks versus 6). What is the new project completion time and critical path? A-D already has 2 hours of slack time‚ therefore if it becomes delayed by 2 hours it will have no impact on the finish time. 4. Suppose that you have extra resources

Problem Set Problem 4.1 [a] Draw a process flow diagram. [b]. The theoretical flow time is 36 minutes: There are three paths through the system: A: Take Order – Food – Deliver – Bill → 4 + 18 + 12 + 2 = 36 mins B: Take Order – Wine – Deliver – Bill → 4 + 4.8 + 12 + 2 = 22.8 mins C: Take Order – Cart – Deliver – Bill → 4 + 10 + 12 + 2 = 28 mins Path A is critical so the TFT is 36 minutes [c]. The flow time efficiency is 36/60 = 60% Problem 4.2 [a] The flow chart of the process

Criticism of "The Sick Rose" By analyzing more information from different authors‚ I was able to draw a greater amount contrast from the authors. I had a better feel for what they were trying to convey when they wrote their critical essays in their books. Whatever the case‚ it was easier to judge "The Sick Rose" by having more sources to reflect upon. Michael Riffaterre centers his analysis of "The Sick Rose" in "The Self- sufficient Text" by "using internal evidence only [to analyze

1. Service design generally differs from product design in which of the following ways? A. Service design tends to focus on tangible factors. B. There is less latitude in detecting and correcting errors prior to delivery. C. There is a lesser requirement to be aware of competitors’ offerings. D. There is less visibility to customers. E. There is no difference. 2. The process of dismantling and inspecting a competitor’s new or revised product for the purpose of gleaning design ideas is called:

sensitivity of the network is increased. The slacks are reduced which lead to a loss of flexibility. The probability of activities delaying the project is increased because the reduction of slack creates more critical activities and critical paths. As in the Gantt chart 3.1‚ there are more critical activities (marked on red). 4. Assume the project is resource constrained and resolve any over allocation problems by leveling outside of slack. What happens? What are the managerial implications? Resource

simulation will provide you with an understanding of how to create a network diagram‚ and how to do a forward and backward pass to determine the ES‚ LS‚ EF‚ LF and slack (float). You will also learn how to determine the duration of the project‚ and the critical path. In this homework assignment‚ you will be working through four Activity In Box (AIB) problems. Using the activity‚ duration‚ and predecessor information given in this document‚ you should first construct a network for each "project." [Each problem

Task:5 Make a critical analysis methodologies used in your project. Explain how your methodologies can be applied to similar types of project and cannot be applied to different type of project. Advantage of Gantt and PERT charts: 1. It gives the start time and end time of the project. 2. It gives you a precise time of each step of the project. 3. It gives you good view of which steps are the main or additional. 4. It provides exact prospective of which step depends on the other
