Abstract
The article presents issues related to creating and realizing added value
by logistic processes and processing in a casting enterprise.
It discusses possibilities of improving systems of casts production by
evaluating labour intensity of casts manufacture and analyzing
manufacturing prime costs. Operations with added value, processes indirectly
creating added value and operations without added value
have been specified. The problem was presented on the example of materials
flow design in a foundry, where casts are manufactured
in expendable moulds and using automated foundry lines. On the basis of the
Pareto analysis, a group of casts was specified whose
manufacture significantly influences the functioning of the whole enterprise.
Finishing treatment operations have been
particularly underlined, as they are performed away from the line and are
among the most labour-consuming processes during casts
production.
