The maintenance and repair of road networks became a key and very important issue,
because of the large increase in length and the limited budget available for maintenance.
This research aims to develop an optimal strategy for maintenance of road i
n order to
distribute the annually limited budget on maintenance programs of road network as a
whole according to multiple objectives.
The proposed mathematical model ensures raising the performance of the road
network in Lattakia for the multiple targets, taking into account the constraints imposed on
the maintenance process, using goal programming technique.
To validate the proposed model we have studied the central road case, and the
samples were Lattakia-Qurdaha and Lattakia-Haffa-Slinfa roads, we have got results
represented by the number of meters can be maintained for each type of maintenance for
every degree and their locations on the road network within the funds available.
A commercial software called lingo has used to solve the linear programming model
(phase 1) and Excel program has used to design the interface for data entry required and
the formation of equations model, Excel program have also used to determine the segments
which have to maintain first on the road network (phase 2).
The proposed model may apply for the different situations of the budget (open,
closed) and for policies and multiple options in order to reach results related to sensitively
model.
