    The simulation of Decision Support Systems (DSS) based on the Assets Management procedure (in managing rock slopes systematically) was demonstrated in this paper. Rock fall Hazard Rating System (RHRS) and Rock fall Mitigation Cost Estimate (RMCE) methods were applied in this paper to mapping, evaluate, and analyze rock fall hazard at the road section of Pekanbaru- Bukittinggi KM 75 to KM 115. Two major elements are subjects to investigate as follow; (i) technical aspect; and (ii) economy one. Based on the RHRS criteria, there should be the riskiest slopes and potential rock fall hazard be prioritized to be managed, they are slopes at KM 80.2 (left), KM 77 and KM 10.3 with RHRS values of 581, 542 and 420 points. The higher RHRS value of the slope the riskiest the slope to the road users. RMCE considers economy aspect to be put into consideration together with RHRS values. Cost estimate for managing rock fall is divided with RHRS is known as cost risk (CR). The CR may comprehensively assist process of DSS for managing the slopes within the road section above by offering flexible options such as; prioritizing the riskiest slopes with moderate CR values eg. Slopes of KM 109.3, KM 77 and KM 80.2 with the BR values of 200.000, 351.000, and 312.000 respectively; or prioritizing the rock fall hazard slopes with the lowest CR values (eg. CR below300.000) for slopes at KM. 109.5, 109.3, 112 dan 80.23.For the first option, it may yield 3 slopes can be repaired, and at second option it may repair 4 slopes.
