DV&O Plan application

Judicial Institutions Department

The Transport and Support Service (hereinafter DV&O) is part of the Judicial Institutions Department (hereinafter DJI). Among other things, the DV&O takes care of the transport of individuals under investigation. For example, from court to prison. Transport orders are planned using the Plan application algorithm.

Responsible use

Goal and impact

This text uses the term litigants. We first explain this term: litigants are all people detained by DJI. The DV&O transports different target groups of people, including litigants.

The algorithm Plan application aims to make a good planning according to the (legal) rules. The most important thing in planning is that litigants reach their destination on time. It is further important in planning that all tasks are carried out properly with the available people and resources (vehicles and equipment). A litigant should be transported as quickly and as safely as possible. This means, among other things, not making unnecessary detours, taking safety into account and making sure any medication an inmate needs is taken care of. The algorithm schedules employees as efficiently as possible. And employees must have the right skills for their tasks.

Considerations

An algorithm is used for transport planning because there are a lot of requests to be processed (about 200,000 per year). These are too many to plan by hand. There are also many rules and exceptions that the DV&O has to take into account.

Human intervention

The algorithm first creates a transport planning and a staff deployment planning. Then a DV&O employee reviews both the algorithm's schedules. If necessary, the employee can change the schedules. After being checked by the DV&O employee, the employee releases the planning. The planning is then put into the Drife information system. And the DV&O employees who have to carry out the assignments are notified.

Risk management

The processing of data by the algorithm must be done safely and carefully. Then nothing can go wrong with the processing of (personal) data. Therefore, only authorised employees are allowed to use the Algorithm Plan Application. What these employees do in the Plan application is properly tracked and monitored. The information system of which the Plan application algorithm is part, meets the requirements for information security of the central government.

Legal basis

By law, the DV&O may transport litigants and process personal data. Listed below are the most important laws governing this.

Under articles 51a to 51d of the Judicial and Criminal Records Act, personal data are processed for the execution of a punishment or measure imposed by the court. For transport of litigants, this is elaborated in:

- Articles 18f and 18g of the Custodial Institutions Act;

- Articles 19a and 19b of the Custodial Institutions Act;

- Articles 11 and 12 of the Custodial Institutions Act;

- The Transport of Offenders Regulations.

Elaboration on impact assessments

When DJI uses important algorithms, DJI always does a study first (a DPIA and an IAMA). This means that DJI looks carefully at the risks and consequences for someone's privacy and interests beforehand. In this way, DJI ensures safer and more reliable use of algorithms.

Impact assessment

• Data Protection Impact Assessment (DPIA)
• Impact Assessment Mensenrechten en Algoritmes (IAMA)

Operations

Data

Below is what data the algorithm uses to schedule transport assignments of litigants:

- the assignment data;

- the data (and risks) of litigants;

- the roster data of employees;

- employees' skills and certifications.

Technical design

Several algorithms are used in the Plan application. These work independently, but are not self-learning. Below, we explain the algorithm for planning transport and deploying security guards during transport.

The Plan application uses an algorithm called VRP. VRP stands for Vehicle Routing Problem. This algorithm calculates how to best plan trips. VRP is often used in logistics and ensures optimal results.

Then, special allocation algorithms are used. These algorithms ensure that each trip is carried out by DV&O employees who have the right skills for it.

When planning, a number of important rules are taken into account. For instance, the algorithm looks at the skills of employees and the characteristics of vehicles (e.g. whether there are separate rooms in the vehicle). But also how exactly the task is to be performed. This involves, for example, determining whether someone can be transported alone or together with others. And which combinations of subjects are possible in that case. Account is also taken of the times when an assignment must be carried out. For example, because an individual has an appointment with a doctor in a hospital. And finally, at which address someone has to be picked up or dropped off.

There are also certain rules that rule out combinations of transport or solutions. This is done according to laws and safety requirements for DV&O staff, litigants and society.

External provider

The algorithm was developed and is managed by More Optimal BV. The Judicial ICT Organisation of the Ministry of Justice and Security ensures that DJI can use the Plan application.
