RC-LIBSEARCH takeAssignmentMain.do?inwokee Locatoraassignment alse Lead Time Audio Max Electronics Company manufactures electronic stereo equipment. The manufacturing process includes printed dirouilt (PC) board assembly, fieal assembly, besting and shipping. In the PC board assembly operation, a number of individuals are responsible for assembling electronic components into printed circuit boards Each operator is responsible for soidering components according to a given set of instructions. Operators work on batches of 50 printed drouit boards Each board requires 4minutes of assembly time. After each batch is completed, the operator moves the assembled boards to the final assembly area. This move takes 9 minutes to complete The final assembly for each stereo unit requires 19 minutes and is also done in batches of 50 units. The batch of 50 stereos is moved into the test building, which is across the street. The move takes 20 minutes. Before conducting the test, the test equipment must be set up for the particular stereo model. The test sebup requires 30 minutes The units wait while the setup is performed. In the final test, the 50-unit batch is tested one at a time. Each test requires 9minutes. The completed batch, after all testing is sent to shipoing for packaging and final shipment to customers. A complete batch of 50 ueits is sent from testing to shipping. The Shipping Department is located next testing. Thus, there is no move tive between these two operations. Packaging and labelieg requires t1 mibutes er t 1. Determine the amount of value-added and non-value-added lead ime and the value-added ratio in this process for an average stereo unit ln a batch of 50 units Categorize the non-value-added time leto wait and move time. Round the percentage be one decimal place s) valu-added minutes 13 mis Non-value-added minutes wat time 2.150 x mi 29 min 2.179 x min ,193 xmin Total lead time value-added ratio (as a percent 2. Move timme i n this process could best be reduced by a. Doing mothing from a process orientation to a product orientation tecreasing banch sizes Ciminatino the testing stapExplanation / Answer
1.
Value added minutes = Board Assembling + Final Assembling + Testing + Packaging and Labelling
..................................= 4 min. + 19 min. + 9 min. + 11 min.
..................................= 43 min.
Move Time = Time needed from assembling to final assembling + Final Assembling to testing
...................= 9 min. + 20 min.
...................= 29 min.
Wait Time = [Total time required x (Batch Size - 1)] - Time Required for 1 batch
.................= (43 min x 50) - 43 min
.................= 2,100 min
Total Wait time = Wait time + Testing setup time
........................= 2,100 min + 30 min
........................= 2,130 min
Total Non Value Added Time = Total Wait time + Move Time
...............................................= 2,130 min + 29 min.
...............................................= 2,159 min.
Total Lead Time = Total Non Value Added Time + Value Added Time
..........................= 2,159 min. + 43 min.
..........................= 2,202 min
Value Added Ratio = Value Added Lead Time / Total Lead Time
...............................= 43 min. / 2,202 min
...............................= 1.9 %
2. Move time in this process could best be reduced by, changing the layout from a process orientation to a product orientation.
Value Added Minutes 43 min Non-value-added minutes: Wait Time 2,130 min. Move Time 29 min. Total non-value added time 2,159 min. Total lead time 2,202 min. Value-added ratio (as a percent) 1.90%Related Questions
