Constellation Sports Scheduling Software System is a professional scheduling solutions for sport federations and anyone who organizers sports competition events.

With constellation you can create schedules in minutes, not days or weeks. If you have created sport schedules manually, with pen and paper you know how difficult and time consuming it is. If you are trying to treat each team fairly, it is even more difficult.

As amateur and professional sports leagues proliferate and grow in size and complexity, organizers are increasingly turning to computer assisted scheduling. Sports scheduling is an area in constraint programming. The generation of sport event calendars is a combinatorial problem that combines features both from tournament scheduling problem and from the travelling salesman problem.

In early stage, we concentrate on a core problem that inevitably comes up: determining whether a set of constraints on the schedule is feasible. Through DUE DILIGENCE we will assure a feasible set of constraints which can provide a convergent timetable. This is often called the "timetabling" problem of the scheduling process.

Constellation can handle sports schedules of any size and complexity. Sports scheduling is an important area of constraint programming. Optimised schedules have many benefits for the divisions/leagues and respective clubs/teams: such as higher incomes, best solutions obtained for real-world instances, lower management costs and fairer more balanced seasons.

INVENTION & INNOVATION -The Sport Events Expert System
When you improve something by an order of magnitude, you have not made something better - you have made something new. CONSTELLATION has boosted Italian Football Federation productivity in Milan on unprecedented level.

During enrolment of teams into competitions, the Constellation scheduler enables an easy input and manipulation of:
- scheduling preferences and
- setting all teams scheduling constraints
It gives you absolute control over all aspects of the fixtures, and creates solutions effortlessly and in harmony with the team scheduling and calendar constraints.

The user interface is clean and seamless. The Constellation web application suite comes fully documented with searchable online help pages, with solutions and examples to any use case. Clubs can simply fill in the team preferences and constraints on the web.

Constellation automates the sport season schedules. Constellation automates round-robin league schedules, cross divisional schedules for any sport that requires team pairings (binding) and other constraints.

---------------------------
AUTO ENROLMENT
---------------------------
Constellation eliminates the need to enter information by league managers. Constellation automates the complex data entry.
It is expected that the data of the clubs and their relative teams as well as desires fields, match-time can be entered directly on web, by the club managers, themselves (and not by the league operators) Web form data entry is quick and intuitive.
In other words, in a few minutes, every club can inserts its data and team's scheduling preferences. Immediately, all the information pertaining to the teams enrolled to competitions are available to league operators.

The user interface is clean and seamless. The Constellation web application suite comes fully documented with searchable help system. Clubs can simply fill in the requested data on the web in the wizard like interface.

These, then, can go directly to division grouping, and schedule processing, jumping another step that usually requires weeks of frustrating work and complex control.

MyConstellation features:
-------------------------------

An important feature of the Constellation scheduling software is that it has user access types.
This means that you can control what different organizations, clubs, and users can access when they log in.
They can see only events scheduled for them.
Constellation users' access levels and R/W rights are managed by user-manager-application.


Limiting a user to only see the relevant appointments and events
Allowing a federation help-desk personnel to book a venue, but have limited access to other parts of the system.
Allowing view-only access while restricting the ability to cancel or change already scheduled appointments.
> Simultaneous multi-user support

CONSTELLATION INSCRIPTIONS – SCHEDULING PREFERENCES OF TEAMS
---------------------------------------------------------------------------------------------------------
Constellation database contains:
- all competitions of a sport season,
- all clubs with their respective teams, officials, players, team player rosters, fields/venues and Constellation Graph with preferences:
- geo-localised fields venues,
- scheduling preferences of teams
- complementarity/pairing constraints between the teams playing on the same day home or away

CONSTELLATION GRAPH is a framework for thinking, viewing and manipulating of the scheduling constraints and scheduling preferences of teams. Constellation Graph looks like an ordered interactive table, where you can easily manipulate the preferential week days and times on the venue fields of teams' matches.
It has an intuitive interface. The Constellation Graph is an interactive user-friendly form for specifying scheduling preferences of teams and their XY pairing constraints during the match season.

It also has an interface with a formal syntax that allows a precise definition of the complementarity/pairing constraints between the teams playing on the same day, even between different clubs.
CONSTELLATION GRAPH is an important tool for configuring a feasible set of constraints on the schedule, so that the convergent "timetabling" of the scheduling process can be successfully accomplished.

The software allows you to define up to 200 different competitions, and unlimited number of venues; and to automatically create a divisions schedule for up to 500 teams per competition.

The CONSTELLATION GLOBAL CONTROL will check the correctness and completeness of all required data and possible venue timetable conflicts, before you start with the team assignments in to divisions.

----------------------------------------------
CONSTELLATION VENUES/FIELDS
----------------------------------------------
It is easy to set field timetable constraints, game length for each competition.
There is also a feature for timetable conflict resolution.

----------------------------------------------
CONSTELLATION Data validation
----------------------------------------------
Constellation assures correctness and completeness of all scheduling requirement data.

We focus on a core problem that inevitably comes up in data entry: determining whether a set of constraints on the schedule is feasible and whether some data are missing.

Data integrity control is exerted on every process that uses user specified data to ensure the continued correctness of all information.

Possible stadium timetable conflicts will be eliminated before one starts with the assignment process of teams to divisions.

---------------------------------------------------------
ASSIGNMENT OF TEAMS TO DIVISIONS

Fixtures management
------------------------------
WHAT IS FIXTURE?
The Fixture is scheduled sport event: (match-time, date, venue, home team, guest team)

Constellation Fixtures management utility will help you organize competition events; enable automatic schedule generation and eventual rescheduling of games.
Scheduler employs optimized balanced round robin algorithm. Manual adjustments are possible.

Constellation enlists open game time slots to help you reschedule rainouts or cancellations.
A fixture can be Cancelled, Postponed or Abandoned. But we can say that more than 95% of fixtures become effective sport events.
The Constellation fixture scheduler creates fixtures for all teams in a division on the specified dates and times, respecting all binding/pairing constraints with other teams, whenever it is possible.
FIXTURE should try to meet all constraints.
Before start assigning teams in divisions you have to set all CONSTELLATION GRAPHS for each team of each club:
a/ Set the dates and times when fixtures should take place each week, and venue availability calendars, i.e. availability and preferred calendars for league, divisions, teams and venues
b/ Setup exceptions dates when fixtures should not take place e.g. December 25th
c/ Setup the teams in your club(s) and the venues where teams play.
d/ The CONSTELLATION scheduler enables venue sharing between leagues, divisions and teams
e/ If all constraints cannot be met then conflicts can be resolved via the conflict checker.
f/ venue and team compatibility binding constraints setup

---------------------------------------
FIXTURE STATUS REPORTS
