The number of employees required to operate a continuous operation was determined. The fixed and variable costs of the operation were separated, generally along the lines of labour and stores components. Proprietary `MicroPlanner' scheduling software was used to assess resource utilisation under the constraints generated by seven-day operation to determine the level of resources required and ensure that the maximum use was being made of all resources. The mine economic model was used to account for both the fixed and variable costs of the various task to determine the cost and net revenue of the various scenarios. The analysis indicated that mine output could be increased while reducing the unit production cost. Several eight- and 12-hour, seven-day rosters were sourced and ranked for their potential to improve production and communication, and for their effect on employee health and lifestyle.
