Correct Answer - Option 1 : Flow diagram
- In a manufacturing shop, there is the movement of men and material from one location to another.
- The flow diagrams indicate the movements while the work is being accomplished.
- A flow diagram is drawn to scale, in which the relative position of machinery, jigs, fixtures, are shown and the path followed by the men and materials are marked.
Steps in drawing a flow diagram:
- The plan of the work area is drawn to the scale
- The relative positions of the machine tools, benches, stores, racks, inspection booths, etc. are marked.
- From the different observations, the actual path of the materials or the worker on the diagram indicates the direction of movement. Different movements are marked with different colours. The process symbol can also be used in the diagram.
Flow process chart -A flow process chart records all the events in sequence using process chart symbols and marks distance and time taken to complete an activity. It utilizes symbols of operation, transportation, inspection, delay, and permanent storage.
Types of flow process chart:
- Man/worker type
- Material type
- Equipment type
Two-handed process chart - The two-handed process chart gives a synchronized and graphical representation of the sequence of manual activities of the worker. It is called two-handed process chart since it records the activities of the left hand and the right hand of the worker as related to each other. A time scale can also be provided on the chart. This chart is used for repetitive works of short duration.
Gang process chart - Gang process chart is another type of multiple activity chart that portrays the relationship of the activities carried out by the different members of a group (gang) with respect to the one another while doing a job. The aim of the gang chart is to reduce idle and ineffective time and to improve the efficiency of gang operation.
