3 - 3 IE (Industrial Engineering) Analysis Techniques

IE (Industrial Engineering) analysis techniques are techniques for the numeric and engineering management and operation of work. These aim to eliminate irrational effort (i.e., a state of burden or load exceeding capacities), wasted efforts (i.e., a state of burden or load falling short of capacities), and irregular efforts (i.e., a state of the previous two states appearing in turn).

(1) Work analysis

Work analysis investigates and analyzes actual work conditions to clarify work (i.e., work to be improved) that generates irrational, irregular, and wasted efforts.

• • Process analysis
  This analyzes work processes to clarify how resources are involved in each process.
• • Motion analysis
  This clarifies the human behaviors that are necessary for carrying out work.
• • Therbligs
  Therbligs are used in motion analysis. They are 18 basic motions that are broken down from human motions, and the 18 symbols that are used to represent the basic motions.
• • Time analysis
  This clarifies the times for motions that are necessary for carrying out work.
• • Stopwatch method
  This is a work time analytical technique that measures work time by using a stopwatch or other timer.
• • Operation analysis
  This clarifies the operational status of persons or machines that is involved in work.
• • Work sampling method
  This is a technique that performs numerous instantaneous observations of what work status the observation target was in at certain points in time, and from that, estimates operational status, work time, and other factors. · 1 question

(2) Work improvement

Work improvement is the elimination of the irrational, irregular, and wasted efforts in work that are targeted for improvement. It sets standard work times and other measurements for making effective use of human and physical resources.

• • PTS (Predetermined Time Standard) method
  This is a method that breaks down the work that is performed by people into basic operations, and from the standard time that is defined in advance for each basic operation, calculates the standard work time. It may be used in time analysis of work for which measurement of work time is difficult, and in estimating work time.
• • Experience estimate method
  This is a method that determines standard work time through the experiential decision of people who are involved in the work.
