Workshift scheduler for a helpline

Workshift scheduler for a helpline

Code written in Python finds the best possible schedule for volunteers while incorporating constrains and special requirements using CP-SAT Solver (Constraint Programming - boolean SATisfiability problem Solver).

Java version is in development.

The problem

Arranging volunteers for a helpline service for the period of one month.

There are three types of work that could be done on the same day:

• Phone shift: Every day.
• Chat shift: Mondays and Wednesdays.
• Observer shift: Any day.

Constraints:

Properties of each volunteer:

• Available days.
• Function: doing phone, chat, both or observation for training purposes.
• Maximum amount of weekend shifts.
• Whether their shifts have to be on separate weeks.
• Whether they welcome observers.
• Whether they want to work alone.
• Whether they cannot yet work alone.
• List of people they do not want to work with.

Each volunteer has to have 4 days between their shifts.

Priorities:

1. Have minimum one volunteer for each day.
2. Fill chat shifts.
3. Have a second volunteer even on phone days.
4. Employ observers on days when there is only phone shift.

Objective:

Maximize filled shifts.
