Title Design and implementation of schedule risk assessment system under multi-resource constraints
Abstract
When managing projects in daily life, inevitably there are always some potential risks in projects owing to large, long-term and a variety of factors. Therefore, the system of this thesis is designed for assessing potential risks in projects. The system help users have a further understanding of projects and be able to prevent risks in advance. This thesis firstly presents research background and research status at home and abroad, then introduces some concepts of project management and risk management. In particular, focusing on resource-constrained project scheduling problem (RCPSP). After that, it states requirement analysis and designs of frame, database and algorithm. Then, describing how to calculate schedule risk and cost risk step by step. Finally, it gives implementation of the system by code and shows effects by interface.
Keywords Schedule risk assessment Monte Carlo simulation Cost risk
