Simo chart

What is SIMO? “SIMO” stands for simultaneous-Motion Cycle chart. It. is one of micro motion study devised by Gilbreth and it presents graphically the separable steps of each pertinent limb of the operator under study. It is an extremely detailed left and right hand operation chart.

What is Simo chart in operations management?

SIMO is an acronym for Simultaneous-Motion Cycle. The chart is used in conjunction with Therbligs to study the detailed activity of a worker, to capture how long the operation takes, and what activities are being performed by each hand. It is one of the tools used by Frank and Lillian Gilbreth.

How is a Simo chart constructed?

A SIMO chart is a chart based on the film analysis, used to record simultaneously on a common time scale the therbligs or a group of therbligs performed by different parts of the body of one or more operators. It is the micro-motion form of the man type flow process chart.

Why is Simo chart important?

A SIMO chart is beneficial since it allows very accurate and detailed analysis. The work cycle form the film can be studied, easily, peacefully and away from the disturbing surroundings of the actual work station.

What is control chart in civil engineering?

The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data.
