Spareparts investigation at Scania Axles

Abstract: An ordinary problem within the industry is a low allocation of resources.
Many industries are only using 50 percentages of their theoretical capacity.
This implies that many companies want to use the existing capacity better,
instead of investing in new machines.

The potential of improvements is large with a resource allocation of 50
percentages. To achieve a better use of these large potential the companies
must have know how of these percentages that are not refined in other words
the losses. How the companies get this knowledge vary depending on the type
of industry. The collection of information can be from case studies to daily
follow-ups. In this report this investigation concentrates on some goods
that are manufactured in low annually series that disturb the ordinary
production.

The work has been done at Scania Axles in Falun and Scania in Argentina. The
report only deals with goods that are produced with cutting machining. Both
factories have modern manufacturing facilities that are adapted for high
volume manufacturing. The production layouts are very flow orientated and
the goods that do not fit to 100 percentages are a disruption.

The aim with this report is to develop a method for analysing flow for the
manufacturing, disturbances and the resource allocation of administrative
resources. In other words, the main focus is to develop a model for
identifying goods that disturb both the administrative- and production
process.

The method used in this thesis is the combining of interviews with survey
investigations of manufacturing personnel, technicians and planning
personnel. This will give a rough view of the goods that are causing the
main disturbances.

The result is that the method developed works very well and certain goods
are identified as large disturbances and need to be investigated more
thoroughly. It was not a surprise that this report found these goods, it was
rather an establishment.
