Routing an asset can sometimes be more complicated than deciding where to put it- it can also become a question of what to put. For example, should OHLs be routed around an Ancient Woodland, or should a cable be HDD'd under it? How do you ensure that these variations are being considered? How can you take the endless combinations of asset types and construction methods into account when you are routing infrastructure?
Luckily, Optioneer has built-in multi-asset functionality. This allows the user to configure Optioneer to consider multiple asset types and installation methods and determine which is best based on many factors such as:
π© technical constraints
π³ environmental sensitivities
π° consenting risk
πͺ¨ geology
π How Optioneer Selects an Asset
First, Optioneer determines what can be placed. As part of the standard configuration setup, the technical limits associated with each asset are specified. This includes no-go zones, elevation limits and slope limits.
Optioneer determines for each point along a route, what can be placed based on these inputs. Letβs take the following example.
Table 1. Example technical limits for wood poles, steel towers and cables. These are all configurable in Optioneer.
Asset Type | Nogo zones | Slope Limit | Elevation Limit |
πͺ΅ Wood Pole | Rivers, ancient woodland | 10Β° | 200m |
β‘οΈ Steel Tower | Rivers, urban areas, ancient woodland | 12Β° | 300m |
π Cable |
| 12Β° | - |
Take the route points in Table 2 as an example. A route point is a sample point along the length of the route. These are typically every 30 meters in Optioneer but for the sake of this exercise, this is simplified to six points. Each route point has a constraint, an elevation and a slope associated with it. First, Optioneer will determine what can be placed at each point. This has been filled out in the bottom three rows of Table 2 below and is depicted in Figure 1.
Table 2. Example route points have associated constraints, elevation and slope values. Based on these, suitable assets can be selected.
Route Point | 1 | 2 | 3 | 4 | 5 | 6 |
Constraint | Agricultural Land | Urban Area | Agricultural Land | River crossing | Agricultural Land | Ancient woodland |
Elevation | 150m | 152m | 150m | 150m | 148m | 130m |
Slope | 2Β° | 11Β° | 2Β° | 2Β° | 6Β° | 5Β° |
πͺ΅ Wood Pole | β | β | β | βοΈ | β | βοΈ |
πΌ Steel Tower | β | βοΈ | β | βοΈ | β | βοΈ |
π Cable | β | β | β | β | β | β |
Figure 1. From the technical limits, Optioneer will determine the candidate assets that can be placed at each point. This example shows the results for the assets shown in Table 2.
None of the route points exceed the elevation in place for the assets.
The slope limit is exceeded for wood poles in a stretch of urban area.
This section of the route contains an urban area, a river and ancient woodland which limit the assets that can be placed here.
For the fourth and sixth route points, we can see that cable is the only suitable asset for these route points, and therefore can be selected. But for the remainder of the route points, Optioneer needs to choose. To do this, Optioneer uses the user inputs from the Installation Priority Component.
From these inputs, Optioneer can deduce user preference, which will typically relate to the cost of the asset. Optioneer can now assign the suitable asset to each route point. See below for the result.
Table 3. Based on the user preference, Optioneer will select the most suitable asset for each route point.
Route Point | 1 | 2 | 3 | 4 | 5 | 6 |
Constraint | Agricultural Land | Urban Area | Agricultural Land | River crossing | Agricultural Land | Ancient woodland |
Elevation | 150m | 152m | 150m | 150m | 148m | 130m |
Slope | 2Β° | 11Β° | 2Β° | 2Β° | 6Β° | 5Β° |
πͺ΅ Wood Pole | β | β | β | βοΈ | β | βοΈ |
πΌ Steel Tower | βοΈ | βοΈ | βοΈ | βοΈ | βοΈ | βοΈ |
π Cable | βοΈ | βοΈ | βοΈ | β | βοΈ | β |
Figure 2. Using the user-defined priorities or preferences, Optioneer will select the most suitable asset at each point from the candidate assets.
π§ Extra things to know about multi-asset functionality:
If there is a point along a route, that Optioneer doesnβt have a suitable asset for, the entire route will be considered infeasible.
