Introduction
In this section, we will describe our decision model. First, a description of what a decision model actually is will be given, to give a basic understanding of the concept. After that, we will explain what our decision model in fact does on a higher level, without all the details inside the decision model. After that, we will explain how the decision model is derived, and how our decision model works on a lower level.
What is a decision model?
A decision model
As described before, our decision model gives as output the best solution for anti-UAV systems based on the input of the user. This user can be, for example, an airport seeking to improve on its anti-UAV systems. Due to the enormous growing list of # Solutions for this, airports may find it difficult to decide for themselves. After our thorough analysis on solutions and types of airport, we have seen that some solutions fit certain airports better than others, and thus we decide to give a systemized model to consult users in this difficult choice.
How does our decision model work?
Our model is a so-called attributed-based decision model. This means that we deconstruct the concept of anti-UAV systems into a set of attributes. Each of these attributes will be quantified by a score between 1 and 10. Then, by asking our user
Attributes of the decision model
We will create a decision model that e.g. airports can use to decide on which type of anti drone system to use. For this decision model, we will look at the main attributes that the anti drone systems have. We will first summarize a list of these attributes to get a clear overview of what we all need to take into account when creating the decision model. These attributes are based on the recommendation report. Here, we distinguished between three different types of airports and identified all the USE-stakeholders for each type. Using this stakeholder analysis, we came up with the following list of attributes.
Airport specific attributes
- Type of the airport (Commercial, Military, Recreational)
- Size of the airport
Preference specific attributes
- Cost of the solution
- Initial costs (purchase)
- Long term cost (maintenance)
- Range of the solution
- Deployment speed of the solution
- Safety of the solution
- Emmision of the solution (CO2)
- Reliability of the solution
- Hindrance to immediate environment of solution
- Types of drones that the solution can be used for
- Scalability of the solution in terms of a growing airport
Questions in the decision model
The next step is for the decision model to rank or score these attributes, so that the decision model can link the final outcome of the attributes to actual solutions. To score these solutions, multiple choice questions were used.
Determining the outcome of the decision model
At the end of the model, we thus get an outcome for each attribute. We then assign weights to each attribute, and this is the final result that will uniquely determine the solution proposed by the decision model.
