PRESANTATION ON CHARTS AND DIAGRAM USE IN

METHOD STUDY

WHAT IS A PROCESS CHART ?

Graphical representation of the sequence of steps or tasks (workflow) constituting a process, from raw materials through to the finished product. It serves as a tool for examining the process in detail to identify areas of possible improvements.

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 CHART

• When 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.

SYMBOLS USED IN FLOW PROCESS CHART

   Operation: Steps in a process of modifying a material, part or product

   Inspection: For quality (test) or quantity (count); doesn't change shape or move product

  Transport: Movement of workers, material or equipment from one operation to another; not  if

movement is part of  an    operation

  ,

Delay: Work waiting between operations

Storage - Controlled, authorization needed to put/retrieve part into storage

EXAMPLES

OF

FLOW PROCESS CHART

Information shown in a flow process chart :-

(1) Type of the flow process chart.

(2) Information of the person producing the part

(3) Information , place ,time & name of operator for whom the product or process is prepared.

(4) Different stages and their involved in the process.

(5) Transport activity , its various stages and distance travelled in it

(6) Different stages of delay ,storage and inspection

(7) Summary information of activities
