IE WORK STUDY LESSON

An application of direct time study. You need, 6 papers, a stopwatch, a direct time study form, pencil box with 3 different coloured pen and e.g. whatever you arrange for your direct time study. The work elements are given for paper folding and stamping process". Aim of this job is to fold 6 papers that are signed with 3 different colours as if they were enveloped. a) 1) Take one paper with your left hand and place it on the table. 2) Take a coloured pen from the pencil box with your right hand.* 3) Write your name on the paper. 4) Use your two hand and fold the papers in half. 5) Put the folded paper 25 cm next to your right with your right hand. 6) Put the coloured pen on table.* Repeat the cycle until all the papers finished. * 2nd and 6th work element are repeated for every two cycle. Apfd is 0.15. Construct the direct time study form and apply all the steps of direct time study. And determine number of observations for 95% confidence, find normal time, standart time, production rate and effectiveness of the worker who is working %70 pace in 8 hour shift (1 hour rest). b) Make your suggestions to improve the process given above. Construct the direct time study form and apply all the steps of direct time study. Find normal and standart times. c) Construct the Therbligs for the job given in part a. (Using two hands) d) Find the predetermined normal times for a and b using MTM-1 and MOST. Compare the results. e) Suppose that this job is one of the task that takes 60% of your working time. For 0.95.5% confidence interval and 20.04 of the true proportion, how many observations should be taken. 1 2 (22/2) p(1-P) n = 20,025= 1.96 20,01=2.33 20.05=1.65 n = za/ p 720/20p ABGABPA ABGMXIA ABGABP*ABPA dof=6 degrees of freedom and a = 0.05, t=2.447 dof=5 degrees of freedom and a =0.05, t = 2.571 dof=5 degrees of freedom and a = 0.10, t = 2.015 An application of direct time study.
