Assembly operations as a basic unit crucially affect the productivity and
overall efficiency of the entire production and assembly process. To increase
the productivity of the entire production-assembly process is necessary to
analyze the individual steps of assembly cycle, eventually find a solution that
would be optimal and was used the gradual, concurrent or combined form of
production-assembly process.
The
first level creates a conceptual model implementing the assembly process.
Indicates the principle of assembly solutions and determines the sequence of
the production-assembly phases. It is therefore appropriate at this phase to
create several structures (sub-assemblies) in order to clear the sequence and
continuity of assembly steps. Assembly of guard portion is characterized by
concurrent form of assembly process. Parts and assemblies going from department
Pn to department Pn+1, and the total time of protector assembly cycle takes
about 5.4 min/unit (one worker).
