In this paper, we consider a retrial and repairable multi-component system with mixed warm
and cold standby components. It is assumed that the failure times of primary (operating) and …

This paper deals with a multi-component machining system consisting of M operating units
along with k types of spare machines. The repair facility comprises of R heterogeneous …

In this article, we survey machine repair problems (MRP) with an emphasis on historical
developments of queuing models of practical importance. The survey proceeds historically …

The present investigation deals with a multicomponent repairable system with state
dependent rates. For smooth functioning of the system, mixed standbys (warm and cold) are …

In this investigation, we deal with performance prediction of machining system with
heterogeneous servers working under N-policy. To make multi-component system more …

The objective of this paper is to study the M/M/R machine repair queueing system with mixed
standbys. The life-time and repair time of units are assumed to be exponentially distributed …

This paper deals with multi-component machine repair model having provision of warm
standby units and repair facility consisting of two heterogeneous servers (primary and …

The present investigation is concerned with the machining system with warm standbys
having R permanent reparimen. When all spares are used, the system begins t-0 work in …

In the present paper we study single server machining system having operating as well as
mixed standby units. The service station is subject to breakdown while in operation. The life …
