Introduction

In this demonstration, we are going to demonstrate the Interdependent Network Analysis to compute the connection loss and service flow reduction of an interdependent network composed of an electric power network and water network. Alternatively, we could also compute the connection loss and service flow reduction for an electric power network and gas network.

Tutorial Example

This advanced tutorial is going to look at how the damage to one utility (a power network) could effect another utility (water network) that might rely on the power network to run, for example, water pumps. Because of this interdependency, looking at the physical damage to the water network is not enough to determine if it can still operate at full capacity after an earthquake event. Using the Interdependent Network Analysis, we can determine connection loss and service flow reduction. To get started, we will need to create a new scenario.

Create Scenario

• If you have not already done so, launch the MAEviz application.
• Go to File -> New Scenario and this should bring up the new scenario dialog.
• Create a scenario with Shelby County, Tennessee as your region of interest and choose the MAEviz 3.1.1 Analysis Defaults as your default set. If you have been following other tutorials you might want to provide the scenario a name such as INA Shelby County.
• After doing this, click Finish to create the new scenario.

Interdependent Network Analysis

First, we will need to determine the physical damage to our water network. To do this, go through the following steps:

• Click on the Execute Analysis icon () to bring up the Execute Analysis wizard.
• Expand the Lifeline category and select Water Utility Network Damage Analysis. Click the Finish button.
