Ergodic and light traffic properties of a complex repairable system
Kovalenko, Igor - In: Computational Statistics 45 (1997) 3, pp. 387-409
A repairable system is composed of components ofI types. A component can be loaded, put on standby, queued or repaired. The repair facility is here assumed to be a queueing system of a rather general structure though interruption of repairs is not allowed. Typei components possess a lifetime...

Optimal Scheduling of a Two-stage Hybrid Flow Shop
Haouari, Mohamed; Hidri, Lotfi; Gharbi, Anis - In: Computational Statistics 64 (2006) 1, pp. 107-124
We present an exact branch-and-bound algorithm for the two-stage hybrid flow shop problem with multiple identical machines in each stage. The objective is to schedule a set of jobs so as to minimize the makespan. This is the first exact procedure which has been specifically designed for this...

On the construction of component importance measures for semi-Markov systems
Hellmich, Mario; Berg, Heinz-Peter - In: Computational Statistics 77 (2013) 1, pp. 15-32
In this paper we consider semi-Markov reliability models of systems with discrete state space in a setup general enough … based on transition rates and interval availability, respectively. For these importance measures we study both the time …

Range reliability in random walks
Vallois, Pierre; Tapiero, Charles - In: Computational Statistics 45 (1997) 3, pp. 325-345
This paper introduces a definition of reliability based on a process range. Thus, process failure is defined when the … probability distribution of the range is then given and the process reliability over long periods of system operations are then … reliability) are also used to motivate the usefulness of range processes in reliability studies. Finally, we point out that there …
