Abstract. A simple step-stress accelerated life testing plan is considered when the failure times in each level of stress are geometrically distributed under Type-I censoring. The problem of choosing the optimal plan is investigated using the asymptotic variance-optimality as well as determinant-optimality and probability-optimality criteria. To illustrate the results of the paper, an example i...

Individual-based simulations are an important class of applications where a complex system is modeled as a collection of autonomous entities, each having its own identify and behavior in the underlying simulated space. The main drawback of such simulations is that they are extremely compute-intensive. We consider the class of individual-based simulations where the simulated entities interact wi...

The theory of distributed detection is receiving a lot of attention. A common assumption used in previous studies is the conditional independence of the observations. In this paper, the optimization of local decision rules for distributed detection networks with correlated observations is considered. We focus on presenting the detection theory for parallel distributed detection networks with fi...

This paper presents a methodology that allows the modeling of distributed discrete-event systems to be used in a single threaded simulation. It is assumed that the distributed system is described by a collection of independent models, one for each component. This is in contrast to distributed simulation where the simulation itself is distributed. We accomplish this task by including all of the ...

A mis padres, que valen más que cien maestros. ABSTRACT I ABSTRACT Despite the well known advantages of distributed processing for intensive computations like simulation, frameworks often fail to exploit them. A distributed simulation is harder to develop than a sequential one, because it is necessary to interface and map activities to processors and handle the ensuing communication and synchro...

Distributed simulation is generally not considered as an option when companies are deciding about their simulation methods. This might be due to the lack of distributed simulation software available or the complexity of implementing a distributed simulator. This paper presents aspects which should be considered when planning a distributed simulator and an experimental distributed simulator, Diw...

Parallel and distributed simulation (PDS) over the one and a half decade of its existence has turned out to be more foundational than merely solving the causality preservation di lemma in partially ordered event structures as they occur in parallel and distributed simulation executions. Today’s availability of parallel and distributed computing and communication technology ha.s given a new rele...

The efficient simulation of a multi-agent system presents particular challenges which are not addressed by standard parallel discrete event simulation (PDES) models and techniques. While the modelling and simulation of agents, at least at a coarse grain, is relatively straightforward, it is harder to apply conventional PDES approaches to the simulation of the agents’ environment. The efficient ...
