Today, many global industries have difficulties meeting their transfer of production cost targets; the complexity in transfer of production is often underestimated. The aircraft manufacturing industry is a relevant example of a global industry, as many aircraft manufacturers produce parts in different areas of the world. The aircraft manufacturing industry include highly complex production tech...

This article presents theoretical basis of spare parts inventory management in manufacturing company. Basis definitions, allocation and differences in spare parts inventory management were compared with other manufacturing inventories. The issue of spare parts inventory management is emphasized in aspect of maintaining continuity of production and generated costs of maintaining inventory.

The purpose of the report is to describe the state of the automatic controlling equipment parts market in the Iberian countries, to present actual and retrospective information about the volumes, dynamics, structure and characteristics of production, imports, exports and consumption and to build a forecast for the market in the next five years.

For comparative purposes, a 200 volt dc system for a large modern commercial aircraft has been designed and Its weight compared with that of a conventional three-phase ac system. To obtain necessary design informatlon, studies have been made of a 50 kW brushless dc generator, the problem of circuit Interruption, conversion equipment and brushless motors. The vulnerability of the system due to t...

This paper considers the problem of scheduling maintenance actions for identical aircraft gas turbine engines. Each one of the turbines consists of parts which frequently require replacement. A finite inventory of spare parts is available and all parts are ready for replacement at any time. The inventory consists of both new and refurbished parts. Hence, these parts have different field lives. ...
