Hi all,
In my company (large steel-processing) the welding machine to create welds between coils faces a lot of availability losses.
Besides this weld breaks in the production line downstream the welding machine are occuring, resulting in quality losses. It is obvious that the weld breaks are caused by bad welding quality, which may be a result of a bad condition of the welding machine.
In order to improve the performance of the welding machine and simplify the analysis I divided the welding machine in several sub-systems. It is possible to allocate the availability losses to specific sub-systems by analyzing the failure registration system. Based on the allocation of the availability losses it is possible to define new maintenance policies to utimately improve the performance of the welding machine.
However, I have no idea how to allocate the quality losses to the identified sub-systems? And how to determine which maintenance policies can be used to avoid quality losses.
Do you know some methods of how to do this? A quantitative method would be most desirable, however a qualitative method is also sufficient. The ultimate aim is to improve the maintenance strategy (consisting of different policies) for the welding machine.
Thanks in advance!
