Explain 3 Multiple Choice Operations Concept
Problem- Nine (9) welders who perform the identical short-cycle job were observed by a time + motion engineer over four (4) cycles each. The total time recorded was two-hundred-ten (210) minutes. The performance rating for a particular welder was established at ninety-two percent ( 92% ). Additionally, each welder is granted a twelve percent (12%) allowance for personal needs, fatigue, and routine delays.
Part 1- What is observed time (OT) for this job
Part 2- What is normal time (NT) for the selected welder
Part 3- What is the standard time (ST) for the selected welder
You need to describe the three multiple choice operation concept and solve the above problem.
