Flow Process chart

What is the purpose of a flow chart?

• It is a picture of a process• It is drawn with symbols representing different types of activities• It defines the system being studied.• It documents changes to the process.

Why are flow charts useful?• They provide a visual for students to see steps in a process.• They can be used as an assessment to check for student understanding.• They can help organize classrooms and minimize transition times.

Flow Diagram

A flow diagram is a graphical means of presenting, describing, or analyzing a process & movement of material, men etc.

This is done with the help of all five symbols which represent steps in a chain of steps.

These all symbols are connected to other one by lines and arrows which represent sequence and dependency relationships (i.e., X must be done before Y can be done).

Definition

Objectives Of Flow DiagramThe flow charts indicates the sequence of events they do

not show the movement of men, material etc but the path of movement can be better visualized by a flow diagram.

Flow diagram is drawn to scale.It shows the relative position of machines, jigs, fixture,

gangway etc and mark the paths followed by men and material.

Distances between two location is indicated in flow diagram.

Steps in drawing a Flow DiagramDraw to scale the plan of the work area.Mark the relative position of machine tools, benches,

store, racks, inspection tables etc.From the different observations, draw the actual

movement of the material or worker on the diagram.Indicate the direction of movement.Mark the distances between consequence two locations.

CHARTS AND DIAGRAMS USED IN METHOD STUDY

Following chart are used in method study :-

(1) OPC - Outline process chart

(2) FPC - Flow process chart

Man type

Material type

Equipment type

(3) Two handed process chart

(4) Multiple activity chart like man and machine chart

(5) SIMO chart

The following diagram are also used in method study.

(1) Flow diagram

(2) String diagram

(3) Cycle graph

(4) Cronocycle diagram

(5) Travel diagram

FLOW PROCESS CHART

FLOW PROCESS CHARTWhen the overall idea of the process has been established it is

possible to go into greater details. Flow process chart can be defined as a graphical presentation of all operations, inspections, delays and storages occurring during a process or procedure which includes information considered necessary for analysis like time required, quantity and distance moved etc.

TYPES OF FLOW PROCESS CHART

Man type - It records what the worker does.

Material type - It records what happens to the material.

Equipment type - It records how the equipment is used.

Flow Process Charts A flow process chart is a chart of all the

activities involved in a process. It is similar to an operations process chart,

except that more detail is shown by including transportations and delays as well as operations, inspections, and storages.

Not usually used for entire assemblies, it is used for just one component (or operator)

Add in information on: Operation duration (time to complete) Distance traveled (for transport operations)

Good for showing savings of a new method.

Flow Process Charts (Cont.)

Process charts summarizes the whole process

They are used to compare the existing and the proposed methods

Process is observed, who, what, where, when, and how questions are asked

Every detail is understood and the chart of the existing situation is drawn

Process Chart Symbols

Indicates the main steps in a process, method or procedure.Usually the part, material or product concerned is modified or

changed during the operation.

2.Inspection

Indicates an inspection for quality and / or check for quantity

1.Operation

3.Transport

Indicates the movement of workers, materials or equipment from place to place

4.Temporary Storage or Delay

Indicates a delay in the sequence of events : for example, work waiting between consecutive operations, or any object laid aside temporarily without

record until required.

5.Permanent Storage

Indicates a controlled storage in which material is received into or issued from a store under some form of authorization; or an item is retained for reference purposes.

6.Combined Activities

Indicates a controlled storage in which material is received into or issued from a store under some form of authorization; or an item is retained for reference purposes.

Before and After Comparison Flow Chart

Example Typist has to take dictation from the author’s

office. He has to type the letter, copy the letter and get letters attested by the author. He has to prepare the envelope and put these letters in the envelope. Finally place the letter and copy aside the tray. Author’s office is 20 feet away from typist office.
