TIME STUDY AS A METHOD FOR MEASURING MACHINERY PERFORMANCE
By T. J. MURRAY and E. MEYER
South African Sugar Association Experiment Statiqn, Mount Edgecombe 4300
Proceedings of The South African Sugar Technologists' Association -June 1982
Time study is a method of measuring work done by man and machine. Time study can be used to establish machinery performance standards and to measure actual productivity for comparison with pre-determined standards.

Elemental Time Studies • Elemental time studies record times for machine activities:– from continuous observation of the machine – for a longer period of time • Machine time is divided into elements.
• Each element: – has clearly recognizable starting and ending points– allows consistent timing in the field
Very Interesting

The question and data missing - What are the machine speeds possible? What is the machine speed used?
