Conclusion
The detailed study of operation time in chassis preparation area using MOST has identified that operation times for
Assembly Main Line Stage I and Stage II are 587 seconds (9.79 min) and 474.48 seconds (7.9 min) respectively.
These operation times were critically analyzed with respect to index numbers based on TMU. The operations are
modified by providing bins, hooks at the ‘decking fixtures” and ‘pantograph I arresting arms” at the ‘chassis
preparation area’. The modified operation times for assembly main line Stage I and Stage II are 421.54 seconds
(7.025 minutes) and 383.4 seconds (6.39 minutes) respectively.
This work has revealed that the MOST can be effectively utilized for all the three sequence models such as ‘General
Move’, ‘Control Move’, and ‘Tool Use’. These models were effectively used in the present work to establish new
standard times for certain activities and eliminate unnecessary movements.
