Abstract :
How to balance time, cost and quality is crucial to construction project management. Tradeoff optimization among them is significant for the improvement of the overall benefits of construction projects. Based on inter-related linear programming functions, a model of multi-attribute utility function is established to study the tradeoff among time, cost and quality. Critical path method (CPM) and ant colony algorithm based on modified selection strategy and global pheromone are applied to obtain the optimal decision result. At last, a case study on heavy repair of instrument control system for hot blast stove is given to verify the feasibility and practicability of the model.
