Resource Planning & Scheduling

Only 5.4% of light & heavy industrial projects meet the cost & schedule
70% of capital projects are over budget
85% behind schedule

Sustainable Model of Design and Construction: Prefabrication

• Reduction of cost and schedule;
• Reduced congestion on site and increased workforce safety;
• Reduced defects and improved quality of components;
• Reduced environmental effects and local impacts.


Multi-Objective Optimisation for Holistic Manufacturing, transportation and Assembly (MtA) of Precast Construction

Resource scheduling of construction proposals allows project managers to assess resource requirements, provide costs and analyse potential delays. The Manufacturing, transportation and Assembly (MtA) sectors of precast construction projects are strongly linked, but considered separately during the scheduling phase. However, it is important to evaluate the cost and time impacts of consequential decisions from manufacturing up to assembly. Through our research, we use a multi-objective Genetic Algorithm-based (GA-based) searching technique to solve unified MtA resource scheduling problems (which are equivalent to extended Flexible Job Shop Scheduling Problems) with the aim of minimising time and cost while maximising safety. Our model is evaluated and compared to other exact and non-exact models using instances from the literature and scenarios inspired from real precast constructions.


Our achievements were development of a multi-objective resource scheduling optimization model to:

• identify and evaluate resource requirements;
• meet customer demand;
• ensure reliable and on time programmes.
