Abstract: We present a new perturbation bound in an / /1 M G queueing system with breakdowns and repairs. Our analysis is based on bounding the distance of stationary distributions in a suitable functional space. This leads to understand how the breakdowns of the server will affect the system's level of performance. In order to give an idea about the application of our approach in practice, we ...

Understanding intentionality is a necessary feature of joint activities involving interdependent agents. This challenge has increased alongside the deployment of autonomous systems that are to some degree unsupervised. This research aims to reduce the number of intentionality recognition breakdowns between people and autonomous systems by designing systems to support the awareness of informatio...

During crisis situations, teams are more prone to coordination breakdowns that characterized by a temporary, diminished ability function effectively as team. However, team research currently lacks robust approaches for identifying transitions from effective functioning breakdowns. With the current study, we aimed develop such approaches, and deepen our understanding of how dynamics across vario...

Breakdowns have variantly been described as symptoms or causes of difficulties in the design process [4], instances that lead to the reframing of problems [3], or in a more general sense, as occurrences of object/idea emergence [7], to mention a few. They seem to play a large role in design behaviour. They directly affect the decision making process and subsequently the course of action, and vi...

This paper presents a comparative analysis of communicative breakdowns experienced by participants collaboratively performing a task in three communication environments: face-to-face, mediated by an audio connection, and mediated by both an audio and a video connection. A quantitative analysis showed significantly less breakdown in the copresent condition than in either of the two technological...

The fundamental function of a cellular manufacturing system (CMS) is based on definition and recognition of a type of similarity among parts that should be produced in a planning period. Cell formation (CF) and cell layout design are two important steps in implementation of the CMS. This paper represents a new nonlinear mathematical programming model for dynamic cell formation that employs the ...

Abstract Hot rolling cylinders are the most important machine parts in plastic deformation equipment. They taken out of operation due to breakage caused by predominant action thermal stresses which cause accidental breakdowns mills. In view these aspects, question arose is knowing nature stresses, as well their evaluation. This paper will experimentally determine mechanical and that arise proce...

In the mining industry, inter-connected machinery operates under harsh conditions 24 hours a day. Naturally, this degrades their state, and can lead to premature breakdowns production losses. Condition-based maintenance (CBM) is strategy that plans schedules depending on condition of equipment, aims improve decision-making processes. Data collected from for CBM purposes must be reliable avoid n...
