Abstract:
Productivity measures have been widely used in
manufacturing industry in order to indicate how well resources like
materials, energy and labour are used. The study was carried out on
raw material utilization at blanking stage for firms that process sheet
metal into round blanks for subsequent operations like drawing into
finished products. Blanking data was obtained from selected
companies involved in making of aluminium and steel blanks. From
this data a mathematical model and FORTRAN code was developed
to simulate expected material utilization for various blank sizes.
The findings of the study present model utilization results that are
comparable to actual utilization. The results can thus be used by firms
to bench mark expected actual utilization and continuously improve
to attain the set standards.
