On the production line for checking the quality there were three persons but the rate of rejected products were high. The products were tested and pass through but the rate of rejection were in increasing order.
Case study:
In Millat Equipment Limited (MEL) the axial housing line, hydraulic pump assembly and
Cylinder block line was able to produce 10 products per hour. The shift of each production line is
8 hours so in theory the line should make 80 products in that time. In the axial housing production line one machine produce bottle neck because of variance in cycle time that losses 1 hour. So in this 8 hours shift 1 hour loses were included (12.5%). In cylinder block line the skills of the worker is not good enough to achieve …show more content…
The total loses for each production was (12.5+6.25+10) %_28.75%. rejection due to availability loses+defective pieces were
16.25%

Why Millat equipment limited?
One of our group member was an internee engineer at Millat Equipment Limited during the this summer and he discussed the problems facing by that company with us and highlight the big issue of 28.75% rejection ratio of product in production line. We decide to minimize this rejection ratio through our managerial skills developed in MS311 course.
Graphical representation of Production and workers before:
In axial housing line the production was 57 and workers were 33. In cylinder block line the production was 60 and workers were 15. In hydraulic pump assembly the production was 49 and workers were 23.

Some of the picture related to hydraulic pump infrastructure and imported parts by the company for hydraulic pumps are given below: Generalize Implementation for every production line:
1. Keep clean the workplace from product storage etc.
2. For quality control system hire trained checkers, checkers making report while checking, analysis of reports and take action based on the quality check reports
3. Through training program convey checkers how to check piece correctly and catch the defective pieces. Train them to make checking reports of product.
4. Run quality awareness program for your employees.
5. Each employee need to be understood from the quality standard and everybody have to work to meet quality control and achieve their pre decided goal.
6. No low standard work should be accepted by the following department.
7. In production line each product must be completed before forwarding to the next. I. As usual operators throw pieces under tables when they make mistake or receive
