DESCRIPTION
The project for DUCSA was to develop a system for the input and optimal dispatch of Liquefied Petroleum Gas orders, in real time. In a peak hour the demand reaches 3.000 orders. The system works with a call center software developed for this purpose. DUCSA is an important company in Uruguay, with a revenue of 800 million dollars. The objective was to build an automated reception and dispatch system on-line (in real time). This system allows the customer to provide a high quality service minimizing the difference between the time a service request is made and the arrival of this service. This is done at lowest operative cost (minimum total travel time) and subject to the current load of the system.

Optimization Engine
What is it, and what does it accomplish?
It’s a set of sophisticated optimization algorithms, developed as a “black box” with easily set-up
parameters specialized designed for programmers, that offers solutions for a wide range of
optimization problems, such us distribution and/or collection of products and/or services

• The optimization engine receives the service requests...
• ... and creates a optimal sequence of visits for the available vehicles.
• The system plans in real time as new requests comes up…
• ... assigning new resources only when necessary.• The planned sequences adapts to the new
requests...• ... by reordering the visits sequences in an optimal
way.

Orders Reception
• The call reception is carried out by an operator.• The call center software determines the best
operator and activates the system for the input of LPG order’s information.
• If the detected phone number is registered in the system, the delivery address is confirmed and the service order is requested.
• It is also possible to see the customer’s previous history.
• In case of a non-registered customer pertinent data is required to comply with the delivery. At this moment this order is located by address matching.

GeoCod Engine
After verifying that the street and crossing streets information is completed the coordinates are obtained (by invoking the geocode engine). Depending on the result of this operation a green or red icon is shown. This enables (or not) the user to confirm the geocode.

After geocoding, spatial analysis tasks are done in order to know the customer’s zone (administrative or distribution).

Dispatch
The dispatch is automaticaly done; the optimization engine defines the better vehicle to carry on with the services. The dispatch supervisor, with the status of the system, is allowed to modify the first assignment.

Work Orders
All vehicles are supplied with a PDA to receive the assigned requests. Communications with the vehicle are supported by
wireless technologies (GSM/GPRS), allowing the direct interaction with the system.

Work Orders
The driver must confirm the request, afterwards he will see in detail destiny and delivery time. Once completed he must confirm the ending of the service.
