Dynamics of Pertinent Project Delay Variables in the Thai Construction Sector: Mathematical Analysis

Abstract Project completion behind schedule is a struggle for the construction sector, affecting time, cost, and quality. This investigation has been necessitated by lingering nature of project delay risks despite many extant analyses. study collated expert opinions from Thai sector on salient variables their influence each other DEMATEL-SD analysis. The data were analysed found consistent with Cronbach’s alpha 0.939. Then, DEMATEL technique was used to establish weight factors System dynamics (SD) It discovered that minimising design error at preconstruction stage significantly reduces magnitude delay. Increasing values change order increase rework profile. Besides, delivery within scheduled 232 weeks can be ensured threat error, change, order, rework, productivity problem, improving management. adopted hybrid mathematical system holistically examine risk comprehensively exploring influencing investigating impact scheme. helps stakeholders arrive an effective decision in overcoming risks, thus cost overrun
