This paper presents a variant of a spare parts inventory model with cold stand-by redundancy on system level. Redundancy on system level implies that not all systems need to be operational in order to have the whole system operational. The cold stand

Aim: To develop general applicable models for analysing the capacity needed in appointment-based hospital facilities. Method: A fairly simple analytical queuing model was used to obtain rapid global insight into the capacity needed to meet the norm o

Coordinated condition-based repair strategies for components of a multi-component maintenance system with discounts

Autor: Diederik J.D. Wijnmalen, J.A.M. Hontelez

Publikováno v: European Journal of Operational Research. 98:52-63

This paper presents a heuristic algorithm for computing upper and lower control limit values for the repair of components (which need not be identical) in a multi-component system. The cost structure is composed of repair, operating and failure costs

Optimum condition-based maintenance policies for deteriorating systems with partial information

Autor: Helen H. Burger, J.A.M. Hontelez, Diederik J.D. Wijnmalen

Publikováno v: Reliability Engineering & System Safety. 51:267-274

Systems are considered which deteriorate as time goes on and whose conditions can be observed. The optimum maintenance policy with respect to cost is determined, based on a continuous deterioration process, by formulating the decision process as a di

Review of a Markov decision algorithm for optimal inspections and revisions in a maintenance system with partial information

Autor: J.A.M. Hontelez, Diederik J.D. Wijnmalen

Publikováno v: European Journal of Operational Research. 62:96-104

In a previously published paper Tijms and van der Duyn Schouten proposed a special-purpose policy iteration algorithm for optimal inspections and revisions in a maintenance system with partial information. In this paper we point out some shortcomings

Background. Little research has been performed on designing appointment systems for the preoperative assessment clinic (PAC). We aimed to investigate how two organizational planning difficulties, (i) long access times and (ii) long waiting times, cou

An Unmanned Air Vehicle (UAV) is an unmanned, remotely controlled, small air vehicle. It has an important role in anti-surface warfare. This implies over-the-horizon detection, classification, targeting and battle damage assessment. To perform these
