Question

The photo to the right shows an operator folding cartons. Assume she does one t a time. She pulls one flat cardboard sheet from the right side with the right hand (RH) to the assembly area. She grasps the end flaps with both left hand (LH) and RH simultaneously. She bends the flaps in ward and locks them. She grasps the top open end with the RH, leaving the LH at the folded end, and rotates the carton 90 degree. She grasps the end flaps with both hands, be bends them inward and locks them. She moves the finished carton to the holding area to the left (not visible). Calculate the normal time for performing one carton assembly using MOST Develop an allowance factor for an assembly element where the operator is standing in a slightly awkward position, regularly lifts a weight of 15 pounds, and has good light and atmospheric condition. The attention required is fine, the noise level is continuous at 70 dBA, and the mental strain is low, as is the monotony and the tediousness of the work.

Explanation / Answer

Solution:

Constant allowance = 9%
Standing = 2%
Weight lifted(15 lbs) = 2%
Fine attention = 2%
Total = 15%
