ABSTRACT: A false legend about maintenance is that it is only a cost. Of course maintenance costs exist, but in some cases these costs can be seen as investments that increase productivity which reduces the impact of fixed costs and variable costs on the final product, thus increasing the profit.
Maintenance costs include both visible costs and hidden costs, the latter is often more incisive, thus, an effective continuous improvement by sensibly reducing hidden costs can create a tangible profit for a company. The maintenance manager should keep in mind this when asking for maintenance funds, because company boards should be made more conscious of both: profits and costs of continuous improvement.
This thesis answers the question about how maintenance can be used to improve the performance of a production system.
As earlier studies have highlighted, within the electronic industry the variability of effective process time plays a major role in the final performance of the production system, it being the reason that we have focused and developed our tools in order to put under control the variability of effective process time. Continuous improvement is a subject that has been discussed in many papers; the innovation of the methodology here introduced lies in the simplicity and in the quantitative indexes introduced to pursue the continuous improvement in the semiconductor industry.
