Transcript of 8.Introduction to Work Study

  • GilbrethMotion Study(Brick Laying Study)TaylorTime Study or Work Measurement (Pig Iron Study)

  • Make life easier and more comfortableGet job done completely and faultlessGet people achieve higher level of living standard

  • Problem SolvingProcess AnalysisOperation AnalysisMicromotion StudyTime Study (Work Measurement)etc.. such as Applied Statistics

  • 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

  • Procedure to describe, systematic analyze and improve work methodThus considerWork processRaw materialsDesign of the outputWorkplace, tools, equipment at each step of the work processHuman activities

  • Scope of Work Study

  • Process AnalysisOperation Analysis(Micro) Motion StudyTime StudyWork Instruction Establishing

  • Process AnalysisProcess Chart Flow Diagram Gang Process ChartEffectively collect information about the workOperation AnalysisMan-Machine Chart Operation Chart Layout of work place

  • Separately constructed for Man - Machine - Material FlowsProcess Chart and Flow Diagram are complementaryAlways complete all chart headings & summary table

  • Process Chart (Flow Process Chart)

  • Layout of Workplace

  • What are revealed information?time consumedtransportation distancerequired man-hourWhat Next ?

  • How to develop a better methodGraphic Tools for the analysis5W + 1H QuestionsECRSChecklistsMore details: Micromotion study

  • What is done?Who does the work? Where is the work done? When is the work done?How is the work done?

  • Output of the questionssObjectives of the workCreativity: Could any other people do this work better in other place, at other time, using other method?

  • Along with 5W1H, TRY US!Eeliminate all unnecessary workCcombine operations (elements of work)Rrearrange sequence of operationsSsimplify the necessary operations

  • Improve the equipment performanceIs current production lot size too large or too small?

  • Create and Change the layout to eliminate distanceIncrease the lot size per tripDo the loading & unloading time take too long?Improve transportation equipment

  • 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

  • Can we create to eliminate temporary storage? Can retention times be shorten?
