Summary

Hastings [1] introduced the concept of repair limits for replacement problems, the basic idea being that if, at a given time, the repair of a vehicle, for example, is sufficiently expensive, then it will be economical to replace the vehicle with a new one. Numerical results also demonstrated that repair limits decreased with age. In addition, it was assumed that, at a certain age, vehicles should be replaced whatever the repair cost. This paper addresses theoretical issues surrounding these questions.

Zusammenfassung

Hastings [1] benutzt Reparaturgrenzen für Ersetzungsprobleme: wenn zu einem Zeitpunkt die Reparatur eines Fahrzeugs (z. B.) hinreichend teuer ist, dann ist es ökonomisch sinnvoll, das Fahrzeug durch ein neues zu ersetzen. Numerische Resultate zeigten, daß diese Reparaturgrenzen monoton fallend sind mit zunehmendem Alter. Außerdem wurde angenommen, daß die Fahrzeuge in einem gewissen Alter unabhängig von den Raparaturkosten ersetzt werden. Die vorliegende Arbeit befaßt sich mit der theoretischen Untersuchung dieser beiden Fragen.
