ABSTRACT
Capacity decisions affect the ability of management in construction industries to meet future demand for clients' requirements and competitiveness in effective project delivery. However, managing multiple construction projects with constraints in equipment and machine capacities requires a systematic and proactive approach towards scheduling and machines loading. This study explores and applies the principles of priority sequencing using Johnson's algorithm in the development of a model for the management of multiple projects under capacity constraints. Hypothetical data was generated for the machines and projects, which were subjected to iterative processes. Priority sequencing rules and scheduling in the order control Gantt chart easily display each equipment formation/loading on each project. The result of the analysis indicates an improvement of 178.74% in the schedule performance due to efficient and systematic utilization of equipment and machine capacities, taking research assumptions into consideration. Training and motivation of managers are recommended to be employed for appropriate capacity planning skills and expertise's required for the management of multiple projects with capacity constraints.
