This document describes Program Evaluation and Review Technique (PERT) and its use in planning and scheduling a project. It provides activity details like predecessor tasks, optimistic, most probable and pessimistic durations. It then shows the steps to 1) draw the activity on arrow (AOA) network, 2) calculate the total project time using PERT, 3) determine the probability the project finishes within 50 and 44 weeks, and 4) find the project completion time with 80% probability.
This document provides information to draw a Program Evaluation and Review Technique (PERT) network and analyze a project. It includes activity information like optimistic, most likely, and pessimistic durations to calculate the expected duration, variance, and probability of completing within given timeframes, like having a 90% chance of finishing within the total time. It asks to: 1) Draw the PERT network, 2) Calculate the total project time, 3) Find the probability of completing within 25 and 20 weeks, and 4) Find the total time with a 90% probability.
1. Draw the line of balance chart for the 65 unit construction project with activities R, W, X, Y, Z.
2. At the 46th week, activities R, Y and X have finished. Activity W will finish at the 49th unit. Activity Z is not yet finished.
3. If activity Z finishes at the 60th week in 39 units, recalculate the rate of Z. The new rate of 6.5 units/week is less than the old rate of 4 units/week, so the recommendation would be to expedite activity Z.
This document provides information to draw an Activity-On-Node (AON) network and Gantt chart for a construction project. It lists 9 activities with their successors, durations, and constraints. The tasks are to: 1) Draw the AON and AOA networks, 2) Determine the critical path and total time, 3) Calculate the early start, early finish, late start, late finish, total float, and free float for each activity, and 4) Draw a Gantt chart showing only non-critical activities.
This document discusses earned value analysis, a project management technique for measuring project performance and progress. It defines key terms like actual cost of work performed, budgeted cost of work performed, and budgeted cost of work scheduled. It also explains how to calculate variances to determine if a project is under or over budget and ahead of or behind schedule. The example shows earned value calculations for a construction project and determines it is behind schedule and over budget based on costs and work completed after 15 months out of a planned 20 month duration.
The project has 8 activities with normal and crash durations and costs provided. The contract time is 20 days with a penalty of 300 LE/day for delays.
To meet the contract time, activities XE, YC, and ZA need to be crashed. Crashed costs are 1140 LE, 1470 LE, and 770 LE to finish in 23, 22, and 21 days respectively. The optimal plan is to crash for 1140 LE to finish in 20 days as required.
After a site update on day 5, the project is expected to finish in 22 days. Activities Y and Z are already complete. Crashing activity D for 1000 LE and activity B for 700 LE, for a
1) The document discusses project scheduling and the critical path method (CPM) for determining the minimum time needed to complete a project.
2) CPM involves calculating early and late start/finish times for activities through forward and backward passes through the network. It also identifies critical activities with zero float that must finish on schedule.
3) The example project network is analyzed using CPM. Forward processing determines early start times, while backward processing finds late finish times. Floats are then calculated to identify which activities have no scheduling flexibility.
The document presents a cash flow analysis for a construction project with 10 activities over 10 periods. It includes tables showing activity costs by day, total costs by period, cash outflows by period from costs, and cash inflows by period from payments. It then calculates payments for each period based on costs, retention rate, profit margin, and down payment. Graphs of cumulative cash outflows and inflows are presented, showing the maximum negative cash flow and indicating a final profit of 4410 LE.
The document discusses the need for construction project management due to the unique challenges of construction projects including their one-of-a-kind nature, involvement of many conflicting parties, and constraints of time, money, and quality. It states that optimal utilization of project resources is the goal of project management. It then provides definitions and characteristics of a project, describes the project life cycle and links between process groups in a phase. Finally, it discusses topics in project management including scope, time, quality, cost, time management, work breakdown structure, project activities, project networks, and activity relationships.

- The company expects continued revenue growth and further margin expansion in the coming quarters.
This document provides an overview of Fortran 77 programming concepts including input/output statements, format specifiers, and the OPEN statement. Key points covered include:
- READ and WRITE statements are used for formatted and list-directed input/output. FORMAT defines the format for READ/WRITE.
- Common format specifiers include I, F, E for integers, reals, and scientific notation. A is for characters.
- The OPEN statement makes a file available for input/output using READ and WRITE and assigns a unit number for file access.
This document discusses various aspects of Fortran 77 programming including:
1. Variable names consist of letters and digits but are not case sensitive. Common declarations include integer and real variables.
2. Fortran 77 uses a fixed format with strict column rules for statements and labels. Comments can start in column 1.
3. A basic Fortran program structure includes the main program name, declarations, statements, and stop/end lines. Subprograms can also be included.
1) Fatigue is failure under repeated loading due to gradual cracking. The S-N curve relates stress levels to the number of cycles to failure. Factors like mean stress, stress amplitude, stress concentration, and surface finish affect fatigue properties.
2) Miner's cumulative damage theory assumes damage from different stress levels is independent and sums fractions of life used to predict failure. It is commonly used to analyze complex variable loading.
3) Goodman, Soderberg and Gerber rules use the S-N curve and material properties to predict if a part under cyclic loading with a given mean stress and stress amplitude will fail by fatigue. They allow determination of maximum and minimum stresses.
This document discusses different hardness tests including Brinell, Vicker, and Rockwell tests. It defines hardness as the ability of a material's surface to resist deformation under an external load. The document describes the process and key parameters for each test such as the indenter type and geometry, typical loads used, how the hardness number is calculated based on measurements from the indentation, limitations and precautions of each test method. It provides examples of calculations to determine hardness values, indentation sizes, and tensile strength from Brinell and Vicker test data.
The document provides information about static shear testing, including direct shear testing, torsion testing, and calculations related to shear stress, shear strain, shear modulus, and other properties. It includes examples of calculations for shear stress, shear modulus, angle of twist, and other values using data from torsion tests on steel specimens of various dimensions under increasing torque loads. Diagrams are presented showing typical shear stress distributions and failure shapes for ductile and brittle materials in torsion testing.
