Introduction
Companies are making greater efforts to petitiveness through enhanced labor productivity,
flexibility, product quality, and automation. The need to adapt products to customer requirements and
yet guarantee short delivery times has emerged a predictor equally as important as price and quality. At
a time petitive advantage is determined by pany’s production, flexibility, and quality,
the area of maintenance management has grown in importance for all kinds of industries (Paz, Leigh,
and Rogers 1994). Maintenance management must look at new ways of ensuring high standards and
reliability of machinery and equipment. A prime factor hindering a rapid improvement of equipment
effectiveness is a centralized anization reflecting a specialist control model. According to
this model, mechanical and electrical specialists are responsible for maintaining and repairing the
machinery and equipment (Wall, Corbett, Martin, Clegg, and Jackson 1990). The shop floor personnel
is involved only to a minimal extent, with little or no responsibility for diagnosis, service, or repair tasks.
However, the specialist control model suffers from various drawbacks:
• The maintenance personnel is often not available.
• The maintenance personnel has to cover a long distance between maintenance workshop and
machine location.
• The tools for diagnosis and repair are stored in the maintenance workshop.
• The required spare parts are not available and must be ordered.
