Gantt Charts & Network Diagrams

Operations managers use many techniques to solve problems. Some of these techniques are graphical and can be solved using software tools and programs. Before you start this activity, review the Excel for Operations Management Software page and download Microsoft Excel and the Excel for OM plugin. You will use these tools to solve real-life problems encountered by operations managers.

How many times have you waited, not so patiently in the departure area, for your aircraft to be serviced before you board? Airport operations managers strive to achieve the shortest "turn around time" possible through a carefully choreographed process. Aircraft only make money when they are in the air!

This chart provides a generalized flow for the turnaround of an aircraft. Your task is to produce a Gantt chart, draw an activity on node (AON) network diagram, and determine the critical path.

Step one: Use Excel to produce a Gantt chart of the aircraft servicing process from the time the aircraft stops at the gate until it is ready for departure. Use this information to create your chart.

· Use the Gantt Chart project planner template to get started. In Excel, select New and then search for the planner.

· Assume that the PLAN START (earliest start time) begins as soon as the predecessor is completed.

· Set the ACTUAL START, ACTUAL DURATION, and PERCENT COMPLETE time to 0 (since we are only using this chart for planning the project).

Once you have completed your Gantt chart, study it and provide suggestions on ways to shorten the turn around time. Remember that some items must be completed before others can start (i.e., the jet bridge must be connected before you can offload the passengers and the aircraft cannot have passengers aboard when refueling).

Step 2: Create a slide to construct a diagram of activity on node (AON) network of the aircraft turnaround operation.

Step3: Use your AON network diagram to determine the critical path and calculate the total time of completion. Make sure to annotate the critical path and time of completion on the slide. Once you produce the AON graph consider what would happen if activity G cabin cleaning could be reduced to: 20 minutes. Write a brief statement on the changes to the critical path and time of completion. Place your statement on the slide.

You will use Microsoft Excel™ along with the Excel OM add-in.

Install Excel OM

After you have installed Excel on your computer, download and install Excel OM.

Use the following resources to download Excel OM:

· Download Excel OM for PCs, Version 5.3 (Pearson) (Links to an external site.)Links to an external site.

· Download Excel OM for Macs, Version 5.3 (Pearson) (Links to an external site.)Links to an external site.

Note for Windows Users: Windows Defender, Windows SmartScreen, and some virus protection programs on Windows computers may prevent Excel OM/QM from installing. For troubleshooting, refer to the Security Program Prevents Installation (Links to an external site.)Links to an external site. document created by the application developer, Dr. Howard Weiss.

Note for Mac Users: The download file for Macs is a ZIP file with the Excel OM/QM for Macs program. Unzip the file. To start Excel OM/QM, open the file named ExcelOMQMV5.xlam.

To use Excel OM, you must launch Excel using the Excel OM shortcut and enable macros.
