T
he main focus of Spain’s Mutual Benefit Association, FREMAP, is to ensure
against injuries in the work place. Founded in 1933, FREMAP occupies
25% of this sector with 1995 revenues reaching 80,000 million pesetas ($660
million). FREMAP activities are divided into four areas: injury prevention,
healthcare, financial support and rehabilitation.
In addition to these activities, FREMAP also manages a preventive medicine
program which requires extensive planning and scheduling.
Client companies specify their timetables for health checks.Then the availability
of medical staff, equipment and mobile and fixed health centers must be
matched against that of the clients’ employees.
Since the number of appointments is constantly increasing, it became urgent to
optimize the planning of medical examinations and the procedures for
equipment allocation. ILOG Scheduler helped FREMAP handle this problem.
“ILOG Solver and
ILOG Scheduler
proved to be extremely
powerful products.
Not only were they
intuitive to use but
they also enabled us to
find new approaches
to solving our problem.
They contributed
enormously to a
successful objectoriented planning
application.”

FREMAP works with over 250,000 companies
that employ a total of almost two million
people. It operates four hospitals and 120
dispensaries throughout Spain and employs
over 2,000 people.

ILOG DB Link
ILOG DB Link is a portable C++ interface to
standard RDBMS. It significantly reduces the
amount of time required to connect C++
applications to RDBMSs such as Sybase,
Oracle, CA-Ingres, Informix and SQLBase.
ILOG DB Link automatically passes standard
SQL requests from C++ applications to the
RDBMS, and supports transaction management, data manipulation, and access to the
data dictionary.

ILOG Solver and
ILOG Scheduler
ILOG Solver is a software development tool
to implement resource allocation, planning
and scheduling applications. ILOG Solver is
designed to produce optimum and reliable
solutions for resource allocation problems
while satisfying industry-wide and enterprisespecific constraints and objectives.
ILOG Solver is based on constraint
programming and provides state-of-the-art
and ready to use optimization algorithms.
ILOG Scheduler is its extension module for
scheduling applications. ILOG Solver and
ILOG Scheduler are C++ libraries available
on both Windows and UNIX platforms.

Automatic Appointment Planner
The Challenge
As it sought to expand its preventive medicine program and reach a record of 600,000 completed
appointments before the end of 1996, FREMAP realized it would have to abandon its manual approach to
scheduling and switch to a computerized planning system instead.
FREMAP chose to develop its planning application with ILOG software components. The new system, the
Automatic Appointment Planner, takes into account criteria such as the time and day at which the
employees are available for visits, the location of the appointment, the traveling time, and the availability of
medical staff and equipment. Based on ILOG Solver and ILOG Scheduler, the Automatic Appointment
Planner enables FREMAP to optimize its resources’ usage while improving its ability to react to unforeseen
events.
The ILOG Solution
ILOG Solver and ILOG Scheduler provide the constraint programming engine for the Automatic
Appointment Planner, and ILOG DB Link maintains the connections to the databases. The GUI application is
built using Arthur Andersen Foundation,and is integrated into a client/server architecture distributed over 60
Unix workstations based in Spain. These workstations are used as data servers and are connected to 1,500
486 processor PCs via an X.25 network across 50 regional zones throughout Spain.
Benefits
ILOG Solver can schedule and optimize appointments for 100 people in a few seconds whereas it used to
take hours to produce similar plans manually. The Automatic Appointment Planner can optimize resource
allocations for each plan produced, regardless of the number of individuals to be scheduled - something
which was just not possible using manual scheduling techniques. Further, operators are able to modify
existing plans and immediately recompute examination schedules.
Although the Automatic Appointment Planner was FREMAP’s first object-oriented application, the
developers found the ILOG software components easy and intuitive to use.
By developing a powefull planning application with ILOG Solver, FREMAP is now able to reduce its costs
while offering a better service to its customers.
