Abstract: We present the web service composition system TripICS, which allows for an easy and user-friendly planning of visits to interesting cities and places around the world in combination with travels, arranged in the way satisfying the user’s requirements. TripICS is a specialization of the concrete planning of PlanICS viewed as a constrained optimization problem to the ontology containing services provided by hotels, airlines, railways, museums etc. The system finds an optimal plan by applying a modification of the most efficient concrete planner of PlanICS based on a combination of an SMT-solver with the algorithm GEO. The modification has been designed in order to solve quickly multiple equality constraints. The efficiency of the new planning algorithm is proved by experimental results.
