Work Study: Its History Gilbreth Motion Study (Brick Laying Study) Taylor Time Study or Work Measurement (Pig Iron Study)

IE Techniques ออกแบบ ปรับปรุง ติดตั้ง ระบบการทำงานร่วมกัน ระหว่าง ออกแบบ ปรับปรุง ติดตั้ง ระบบการทำงานร่วมกัน ระหว่าง คน วัตถุดิบ เครื่องจักร พลังงาน เทคนิคการ คณิตศาสตร์ วิทยาศาสตร์ สังคมศาสตร์ ทักษะ ประสบการณ์ การวิเคราะห์ โดยใช้ความรู้ แสดง คาดคะเน ประเมินผล สิ่งที่ได้จากระบบงานนั้น เพื่อ

The Ultimate Goals Make life easier and more comfortable Get job done completely and faultless Get people achieve higher level of living standard

IE Techniques Problem Solving Process Analysis Operation Analysis Micromotion Study Time Study (Work Measurement) etc.. such as Applied Statistics

Work Study Knowledge dealing with the systematic determination of a preferable work method with the time required for the uses of human and equipment to perform such work as well as a development of material & tools to make the established method and time practical

Motion Study Procedure to describe, systematic analyze and improve work method Thus consider Work process Raw materials Design of the output Workplace, tools, equipment at each step of the work process Human activities Method Engineering

Why? Work Study งานเพิ่มขึ้นเนื่องจากออกแบบไม่ดี งานส่วนที่จำเป็น เวลาสูญเปล่าเนื่องจากความบกพร่อง ของผู้ปฏิบัติงาน เวลาสูญเปล่าเนื่องจากความบกพร่อง ในการจัดการ และควบคุม งานเพิ่มขึ้นเนื่องจากกระบวนการผลิตไม่ดี งานเพิ่มขึ้นเนื่องจากออกแบบไม่ดี งานส่วนที่จำเป็น

Scope of Work Study

Work Study Process Analysis Operation Analysis (Micro) Motion Study Time Study Work Instruction Establishing

Effectively collect information about the work Graphic Tools Effectively collect information about the work Process Analysis Process Chart Flow Diagram Gang Process Chart Operation Analysis Man-Machine Chart Operation Chart Layout of work place

Legends Operation Inspection Transportation Delay Storage

Process Chart (Flow Process Chart) Separately constructed for Man - Machine - Material Flows Process Chart and Flow Diagram are complementary Always complete all chart headings & summary table

Process Chart (Flow Process Chart)

Flow Diagram

Gang Process Chart

Operation Chart Record motions of Left - Right hands Only ‘in-work’ and ‘in-move’ No time recorded

Operation Chart

Man-Machine Chart

Layout of Workplace

Work Study: A Trial 30 min.

What Next ? Pin Points !!! time consumed transportation distance What are revealed information? time consumed transportation distance required man-hour What Next ?

How to develop a better method Process Improvement How to develop a better method Graphic Tools for the analysis 5W + 1H Questions ECRS Checklists More details: Micromotion study

5W + 1H Questions What is done? Who does the work? Where is the work done? When is the work done? How is the work done? ? Why should it be done ? Why does she do it ? Why should it be done here Why should it be done this time ? ? Why is it be done this way

5W + 1H Questions Output of the questions…s Objectives of the work Creativity: Could any other people do this work better in other place, at other time, using other method?

ECRS Along with 5W1H, TRY US! E eliminate all unnecessary work C combine operations (elements of work) R rearrange sequence of operations S simplify the necessary operations

& ECRS 5W+1H To Improve Improve the equipment performance Operation Improve the equipment performance Is current production lot size too large or too small? ECRS 5W+1H & at each operation !!!

& ECRS 5W+1H To Improve Transportation Create and Change the layout to eliminate distance Increase the lot size per trip Do the loading & unloading time take too long? Improve transportation equipment ECRS 5W+1H & at each transportation !!!

& ECRS 5W+1H To Improve at each inspection !!! Inspection Create Improve inspection method Are the quality inspections and volume inspections being done at separate processes? Try to combine the two at the same process ECRS 5W+1H & at each inspection !!!

& ECRS 5W+1H To Improve And Finally! and Can we create to eliminate temporary storage? Can retention times be shorten? ECRS 5W+1H & And Finally!
