Methods-Time Measurement Questions and Answers fully solved 2023 Frederick Winslow Taylor: who he be, what did he do? Father of Scientific Management, developed methods to cut costs and increase labor productivity. Taylorism Eliminate idle time. Eliminate duplication of effort. Streamline flow of work. Rearrange task sequences. Make jobs more short to be repititive. Reduce skill requirements of job.

Simplify necessary motions. Speed up motions. Use the most favorable motion sequence. Therbligs 18 kinds of basic motion that are used by workers. PDTS: Predetermined Time Standards (What is the unit and how much is it worth?) Therbligs time measurement. Stated in terms of TMU = 0.036 Seconds. Methods-Time Measurement (4 steps, assumptions) 1) Break tasks into essential elements. 2) Design optimal sequence. 3) Assign predetermined times to elements. 4) Adjust of learning/rest. Assumption: independent, sequential operations How to calculate move TMU? move TMU = (table value) x (weight factor) + constant TMU What is Time Study? What does it determine? What do you need to know for iit? It measures the time it takes to complete components of an activity. It is used to redesign processes and determines standard times for a job. Which elements to define? Beginning and ending task component. Exclusive activity definition. Define parallel activities. Procedure for Time Study (7) 1. Observe preliminary work methods 2. Break job into elements. 3. Find an acceptable operator. 4. Record the time it takes to do an elemental task. 5. Observe enough cycles. 6. Determine performance ratings (Westinghouse system) 7. Assign allowance for learning, delays, fatigue. Time Study: How to calculator normal time and standard time? Normal Time = Mean elapsed elemental time * performance rating % Standard Time = Normal time x (1 + allowance factor) What are some problems with time study sampling? Enough # of samples? Is the task well defined enough, is it consistently developed?
