Preventive maintenance is essential for the smooth operation of any equipment. Still, people occasionally do not maintain their equipment adequately. Maintenance alert systems attempt to remind people to perform maintenance. However, most of these systems do not provide alerts at the optimal timing, and nor do they take into account the time required for maintenance or compute the optimal timin...

The reconfigurable vibrating screen (RVS) machine is an innovative beneficiation machine designed for screening different mineral particles of varying sizes and volumes required by the customers’ through the geometric transformation of its screen structure. The successful RVS machine upkeep requires its continuous, availability, reliability and maintainability. The RVS machine downtime, which c...

This article develops an agent-level stochastic simulation model, termed RAW-ALPS , for simulating the spread of epidemic in a community. The mechanism transmission is agent-to-agent contact, using parameters reported COVID-19 pandemic. When unconstrained, agents follow independent random walks and catch infections due to physical proximity with infected agents. Under lockdown, agent can only i...

Computer networks are present throughout all sectors of our critical infrastructure and these networks are under a constant threat of cyber attack. One prevalent computer network threat takes advantage of unauthorized, and thus insecure, hardware on a network. This paper presents a prototype simulation system for network risk assessment that is intended for use by administrators to simulate and...

The increasing use of on-board sensor monitoring and data-driven algorithms has stimulated the recent shift to predictive maintenance for aircraft. This paper discusses emerging challenges aircraft maintenance. We identify new hazards associated with introduction technologies into using a structured brainstorming conducted panel experts. is facilitated by prior modeling process as an agent-base...

background: chronic infection with hepatitis c virus (hcv) is increasingly recognized as a major global health problem. illicit injection drug use is an important risk factor for the rising hepatitis c virus (hcv) prevalence in ir iran. objectives: the objective of this study was to determine the long-term effectiveness (total quality adjusted life years (qalys) gained) of methadone maintenance...

Agent-based analysis and design is a prospering area of software engineering and several methodologies have been proposed. However, how to evolve the architecture of agentbased system during development is not well addressed. This paper presents 2 kinds of design evolution using a CASE system for OOAD as an example. The first kind of evolution is due to the change of business logic, and the sec...

Industrial necessities claim global management procedures integrating information systems in order to manage and to use the whole information about controlled processes and thus, to assure a good process behaviour. Fault management and maintenance are vital aspects in industrial management, in this sense, maintenance systems should support decision-making tools, new maintenance approaches and t...
