Concept explainers
A.
Interpretation:The network diagram is to be drawn.
Concept Introduction: Network diagram is a graphical representation of tasks in symbols and lines for easy understanding. The networking technique is a method for planning, programming and controlling of work in progress. It is helpful for effective management. It helps the management for decisions.
B.
Interpretation:The critical path is to be detected.
Concept Introduction: Critical path is a method used to evaluate the project. It is used when the activity times are deterministic. It is the longest path in the network. It defines the minimum time required for completion of the project.

- The Mobicom Corporation is in the design phase of a system project. The project manager wants to develop a network analysis diagram to plan the activities of designing the system outputs. The activities are as follows. ACTIVITY PRECEDING TIME[WEEKS] A ----- 5 B ---- 6 C ---- 4 D A,B 7 E C 8 F C,D 10 G D 8 Required Draw a network diagram for the design phasearrow_forwardMake a list of the tasks that is necessary to build a duplex house (around 3000 sft) for you. Develop a table showing each task, its duration, preceding event(s), and expected duration. Develop a Network diagram for these tasks. Highlight the critical path on your Network diagram and find out slack of all activities.arrow_forwardA farm owner is going to erect a maintenance building with a connecting electrical generator and water tank. The activities, activity descriptions, and estimated durations are given in the following table: Activity Activity Description Excavate Erect building Install generator Install tank Install maintenance equipment Connect generator and tank to building Paint finish Check out facility Activity Predecessor b, c, d b e, f a. Draw a complete network for the above problem. b. Determine the critical path and the expected completion time. c. Show a table of detailed activity schedule.

- Find the project duration after constructing the network diagram by using the data provided in Table.arrow_forwardIn the cpm network diagram given below: a-Find the critical path and show it on the diagram. b-(2-3) Determine the floats of its activity.arrow_forwardThe following CPM network has estimates of the normal time in weeks listed for the activities: A(7) B(4) Node A B C D E F G C(2) D(5) F(2) Early Early Start Finish E(4) 1. Identify the critical path and show your answer. Please compute the early start, early finish, late start, late finish time for each node (activities) and Write your answer in the following table. (You may type your answer in a table in MS Word and then paste in the answer box below. Late Start Late Finish G (6) 2. What is the length of time to complete the project? 3. Which activities have slack, and how much?arrow_forward

Develop a Network diagram for these tasks. Highlight the critical path on your Network diagram and find out slack of all activities.arrow_forwardThe director of continuing education at Bluebird University just approved the planning for a sales training seminar. Her administra assistant identified the various activities that must be done and their relationships to each other, as shown in the following table: Click the icon to view the activities. Because of the uncertainty in planning the new course, the assistant also has supplied the following time estimates for each acti Click the icon to view the time estimates. The director wants to conduct the seminar 46 working days from now. What is the probability that everything will be ready in time the standard normal table. (Make sure to round all intermediate calculations for t, and variance to two decimal places) The probability that the seminar will be ready in time is 0.8643]. (Enter your response rounded to four decimal places.)arrow_forwardThe following is the data available for a project: Activity Predecessor Expected Duration (Days) A - 12 B A 9 C B,E 3 D - 10 E D 6 F E 3 G - 2 H G 9 I E,H 2 Expected duration for the completion of the project. Calculate earliest and latest start and finish times for each activity. Draw the network diagram for the project and determine the critical patharrow_forward
- b) – Draw the Activity-on-Node (AON) diagram using the following representation for every node: Activity Description Expected Time ES EF LS LF Slack C.) Complete the following table, determine the expected time of completion assuming that the project starts at week 0 (zero) and identify the critical path for this project. Demonstrate all your calculations. On Critical Path?

Remodel facilities Receive and set up furniture Move in and start up 6 7 a) Complete the following table, calculate the project variance and project standard deviation. Demonstrate all your calculations.arrow_forwardThe Student Affairs Department at UCC has developed a sequence of activities for the University’s Sports Day. The Director has published the activities as shown in the table. All students are expected to participate and all activities are expected to be completed. The activities and immediate predecessors appear in the following table. Develop a network for this problem.
