91.The operation process chart To shows the sequence of all operations ,time ,materials used. From arrival of raw material to the packaging of the finished product.Only Operation and Inspection symbol. ( Out line Process Chart )
11After completing an operation process chart, analysts should review each operation and inspection. 4W 1HWhy is this operation necessary?How can the operation be performed better?Where could the operation be performed at a lower cost or improved quality?
132. The flow process chart แผนภูมิการเคลื่อนที่ The flow process chart contains more detail than the operation process chart.Recording hidden costs such asdistances traveled, delays and temporary storage. ( Nonproductive should be reduce )
23Construct The flow diagram 1. Drawing the plant area ,showing the location of all activities on the flow process chart.2. To sketch in the flow lines indicating the movement of the material one activity to the next.3. Identify each activity the symbol and numbers corresponding to the flow process chart4. The direction of flow is indicated by the arrow.
