THE METHOD FOR IMPROVING STABILITY OF CONSTRUCTION PROJECT SCHEDULES THROUGH BUFFER ALLOCATION / STATYBOS VYKDYMO GRAFIKO STABILUMO UŽTIKRINIMAS PASKIRSTANT LAIKO REZERVUS

Abstract. The actual completion time of construction projects is rarely in accordance with initial plans. This is due to unforeseen events that affect the project execution. In the paper, the authors propose a method of improving the construction schedule reliability. The method is based on the idea of buffers allocation, whose proper sizing helps to reduce negative effects of random conditions on the progress and efficiency of project activities. The authors adopt a proactive approach to the construction of robust schedules to cope with multiple disruptions during project execution, applicable to two processes starting policies (as soon as possible or no sooner than on a predefined date). The proposed method, based on simulation technique and mathematical programming, was illustrated by an example. The results obtained by means of the proposed method were compared, in terms of schedule stability, to those of the float factor heuristic and starting time criticality heuristic procedures. The method allowed...
