Summer Internship and
Mahindra and Mahindra
Project
- Validate and update the data in
MOST sheets (Maynard Operations Sequencing Technique, a method used by
industrial engineers to compute the work content of a given job) used for the
manufacture of Mahindra Double Cabin and Single Cabin Vehicle models.
This required frequent visits to the shop floor to validate
the various moves. It also required a thorough understanding of the process of
assembly.
- On the basis of the above MOST data
sheets compute a precedence diagram ( a chart showing the dependencies of
various tasks)
This required a very thorough understanding of the assembly
procedure – so that sequences could be arrived at.
- Using the precedence diagram,
arrive at a heuristic line balancing code in order to ensure uniform work
distribution.
This required lots of innovative coding – especially to
arrive at the Precedence Matrix (440 x 440)
4. Come up with a
plant layout to unify two assembly lines: The Single cabin and the Double Cabin
lines – in order to de-clutter the inventory and reduce the Non Performing
Assets (NPAs).
Project
completed in stipulated time of 6 weeks and confidential report submitted to
Mahindra and Mahindra Ltd.
Main Problems Encountered In The Project
- Misleading MOST Sheets: The
MOST sheets in use at Mahindra were incorrect. They were misleading. All
these mistakes had to be corrected by going to the shop floor.
- The Precedence diagram required
for the task was unavailable. A diagram had to be made after understanding
the entire process properly.
- After the diagram was made, we
had a matrix of 432 x 432 tasks.
Inputting the matrix by hand would prove to be impossible. So, the
diagram was fed into excel in a connectivity format
- Since the matrix was 432 x 432, and the only compiler
available was Turbo C (which did not accept more than 255 x 255) and the
only computer available a Pentium I, we had to use files to access the
matrix.
