And 11 were identified as non-value added activities as shown in Table 2with this, number of activities were
reduced from 42 to 31. As given in Table 1 there is a reduction of operation time by 54.72 seconds and in Table
2 there is an elimination of operation time by 3 minutes and 4 seconds, hence the total operation time for Body
Side Panel Bonding Process gets reduced to 5 minutes and 53 seconds. With the changes made in 5 activities and
elimination of 11 activities there is a reduction of 41% of operation time. Table 3 shows MOST estimation sheet
with newly established standard time for Body Side Panel Bonding Process.
7. Conclusion
Study of existing set up for assembly of body side panel has revealed that there are 11 non-value added activities
which have been removedthere by reducing the sequence of operations to 31 from 42. These 11 activities put
together were taking assembly time of 3 minutes 4 seconds. And 5 activities were found to be taking more time
than required i.e.; 54 seconds, for these activities new time standards were established. After modification of 5
activities and elimination of 11 activities assembly time reduced to 5 minutes and 57 seconds from earlier 9 min
56 seconds, a reduction of 41% in assembly time.
This work has revealed that the three sequence models such as ‘General Move’, ‘Control Move’, and ‘Tool Use’
used in MOST are found to be very effective in identifying unnecessary movements in assembly process. And
these sequence models were effectively used in the present work to establish new standard times for certain
activities and elimination of unnecessary movements.
