InfoAsset Planner rehab plans can be extremely complicated or very simple. Regardless of how large and comprehensive they grow, or how simple they remain, the same steps are used to create the rehab plan object.
Below are the basic steps for creating a rehabilitation plan:
- In the Operation Center - Analysis tab, rehabilitation plans are the final option for particular facilities. Right-click on the drop-down option and select New.
- Assign the newly created rehabilitation plan with a unique ID and a description. The unique ID may not contain special characters or spaces and is difficult to edit later; the description is more flexible and can easily be edited.
- After clicking OK, the first rehab plan window will open asking you to specify basic parameters.
Facility Scope - Allows you to specify the facilities for which this Rehab Plan may evaluate. Like many analyses in InfoAsset Planner, the facility scope can either include the entire network, only a particular facility selection created by the user, or only facilities with a particular value in the Zone field.
Analysis Result - Here you specify a default Risk ID and/or Survey Import which the rehab plan will be primarily based on. Rehab plans may incorporate multiple risk results or survey imports, but certain conditions statements will specifically look at the risk or survey import specified here. A Risk ID must always be specified here, while the Survey Import is optional.
For most asset types, the Survey Import option is not available. It is only available for gravity mains, laterals, and manholes in the Sewer network.
Replacement Option - You can specify whether a material change will occur during facility replacement. For example, if part of the capital improvement project includes replacing all pipe with PVC pipe, this can be specified here. If the replacement option is not specified, the material of the replacement will be the same as the asset material to be replaced (DI pipe will be replaced with DI pipe, PVC pipe will be replaced with PVC pipe, etc.).
Rerun invalid results only - This last options allows you to rerun only those facilities which have the Pending Rerun field flagged.
This option will still not run Locked facilities; only unlocked facilities with the Pending Rerun field flagged.
- Once the parameters are specified, you may click Next to enter the rehab plan decision tree window. This window is where you may specify your rehab logic. For certain asset types, a default decision tree may be displayed automatically. These default decision trees are only meant to provide you with a starting point; Innovyze does not provide direct engineering advice for rehab planning. Every client's needs are different when it comes to rehabilitation, so it is very difficult (if not impossible) to prescribe a one-size fits all decision tree for rehabilitation.
- In this workspace, you may access the toolbar to help customized the decision tree to meet your logic. Notable options in this toolbar include:
Open/Save/Save To - These first options allow you to save your decision trees to recall in other InfoAsset Planner projects or within the same project. With Save To, you may save decision trees within the database, as media files (.png), or as .xml documents to share between InfoAsset Planner projects.
- You should pay special attention when sharing decision trees between different projects and datasets, however. Because every project contains different data, IDs, and tags, decision trees imported to other projects may try to search for data which does not exist in the new project.
Add Condition/End/Comment - These options allow you to add the three different blocks to the rehab decision tree workspace. The toolbar will highlight the block currently selected.
Conditions are 'Yes, No' questions used to input user logic and point facilities in one direction vs. another. Ends are rehab actions used to classify facilities at the end of a decision tree analysis. Comments do not change facilities direction in the decision tree, but may add supplementary information if desired.
Setting - In rehab plans with survey import data, certain built-in condition statement options reference Major and Minor defects which are categorized with this option. You may enter the scores which specify defects as major vs. minor in this window. Defects scoring greater than or equal to the Major defect threshold are Major defects; defects equal to or below the Minor defect threshold are minor.
For rehab plans without survey import data, this option is not relevant.
- In the workspace, you may drag and draw conditions, ends, and comments. All these items may be connected by dragging and drawing flow arrows. To connect boxes with arrows, simply click and drag within the workspace from one block to the next. The first arrow from a condition (blue) will be "Yes", and the second will be "No." To delete an arrow, select it and click Delete on the keyboard.
Condition statements may be edited by clicking on them and adjusting the parameters in the top-right corner of the window.
- Once the decision tree is complete, you may click Run in the toolbar to evaluate the analysis. If the decision tree is new, InfoAsset Planner may prompt you to save the decision tree to the InfoAsset Planner database so it can be recalled later.
- After running, the rehabilitation summary report will automatically open in the Dashboard. This report should show each facility, the rehab action or end assigned to it, costing information, and other basic information about each facility.
*Note: Be sure to re-run the decision tree any time that the underlying input data changes to reflect the latest results.
