System Configurations

In this paper we describe a new approach and support tool for the modelling and analysis of socio-technical system configurations. This novel approach has been developed for use on systems composed of a wide variety of different components including social and organisational elements, in addition to the more traditional software and hardware aspects. Configuration models of such systems are lightweight and quick to construct and can help to promote understanding by the various stakeholders involved in system development, operation and evolution. These models also provide the data required for performing various useful forms of automated analysis. The results of such analysis can allow managers, administrators, developers and end users to investigate various efficiency, productivity and dependability attributes of the current configuration of a system. This can help support decisions about the evolution of a system by allowing the assessment of proposed changes such as the addition or removal of components, processes and structures. In this paper we utilise a real world case study in order to demonstrate and evaluate the utility of the described approach.

Multiple Criteria Evaluation

Many decision processes in technical and economical sciences require multiple criteria decision making. The most widely applied methods for multiple criteria evaluation of alternatives are based on the evaluation of alternatives in terms of an additive preference function. All of them require the estimation of weights of usually conflicting criteria. There are several methods how to find the weights of the criteria and how to find the evaluation of each solution in each criterion. The decision process based on simple weighted sum of values may not be the best approach in all situations. This paper contains a new approach of the evaluation of measured value set by different mathematical operators than the usually used multiple criteria evaluation methods. The approach was applied in a case study for multiple criteria evaluation. Generally, this new decision-support tool can help in various situations where different types of effects caused by a construction or reconstruction can occur. This is a very frequent situation in dealing with building defects, too.

Reorganization in Multi-Agent Systems plays a crucial role in the dynamic adaptation of the structure and the behaviour of organizations. In order to ensure consistency of the resulting organization, the reorganization process has to be controlled. This paper proposes a novel approach for controlling the reorganization process of Multi-Agent Systems, which are specified and implemented using the Framework OMACS (Organizational Model for Adaptive Computational Systems). The proposed control process is accomplished using the Framework MOP (Monitoring Oriented Programming) for supporting the verification of some reorganizational properties. The proposed approach, supported by a software tool that we developed, is illustrated using a concrete case study.

Purpose Conventional resource-intensive methods for child phonetic development studies are often impractical for sampling and analyzing child vocalizations in sufficient quantity. The purpose of this study was to provide new information on early language development by an automated analysis of child phonetic production using naturalistic recordings. The new approach was evaluated relative to conventional manual transcription methods. Its effectiveness was demonstrated by a case study with 106 children with typical development (TD) ages 8–48 months, 71 children with autism spectrum disorder (ASD) ages 16–48 months, and 49 children with language delay (LD) not related to ASD ages 10–44 months. Method A small digital recorder in the chest pocket of clothing captured full-day natural child vocalizations, which were automatically identified into consonant, vowel, nonspeech, and silence, producing the average count per utterance (ACPU) for consonant and vowel. Results Clear child utterances were identified with above 72% accuracy. Correlations between machine-estimated and human-transcribed ACPUs were above 0.82. Children with TD produced significantly more consonants and vowels per utterance than did other children. Children with LD produced significantly more consonants but not vowels than did children with ASD. Conclusion The authors provide new information on typical and atypical language development in children with TD, ASD, and LD using an automated computational approach.

The idea of the “garden city” was developed theoretically to offer solutions to serious city development problems such as traffic congestion, population, and environmental pollution, among which the transportation is considered the most important. The question is how to develop balanced transportation in a garden city. Transportation is a complex system, particularly in a garden city. Therefore, we establish a new approach named the transportation multiobjective optimization system dynamics  (SD-MOP) model, which firstly calculates the optimal proportion of different transport means with an MOP approach and then applies them to the dynamic transportation system to analyze the results and analyze the influence on the whole system using different transportation means variation. In this paper, we take Chengdu as an example, one of the few cities in the world declared as building a garden city, and then develop some recommendations about world modern garden city transportation system development.

Mission Critical

Cyber-Physical Systems (CPS) often involve complex networks of interconnected software and hardware components that are logically combined to achieve a common goal or mission; for example, keeping a plane in the air or providing energy to a city. Failures in these components may jeopardise the mission of the system. Therefore, identifying the minimal set of critical CPS components that is most likely to fail, and prevent the global system from accomplishing its mission, becomes essential to ensure reliability. In this article, we present a novel approach to identifying the Most Likely Mission-critical Component Set (MLMCS) using AND/OR dependency graphs enriched with independent failure probabilities. We address the MLMCS problem as a Maximum Satisfiability (MaxSAT) problem. We translate probabilities into a negative logarithmic space to linearise the problem within MaxSAT. The experimental results conducted with our open source tool LDA4CPS indicate that the approach is both effective and efficient. We also present a case study on complex aircraft systems that shows the feasibility of our approach and its applicability to mission-critical cyber-physical systems. Finally, we present two MLMCS-based security applications focused on system hardening and forensic investigations.

Abstract The United Arab Emirates Vision 2071 expects the country to become one of the best in the world in several sectors, including education and infrastructure. Highlighting today’s global tendency towards a knowledge-based economy, it drives the need to bridge the academic gap in UAE’s educational system to enhance the nation’s innovation. This gap is best addressed from three different levels, policy level, pedagogical level, and socio-urban level. The UAE is working on developing its educational system by emphasizing its importance through the UAE future strategies and policies, that will upgrade it with its new pedagogical facilities. This study proposes the “District-Learning”, a novel approach to upgrading the UAE educational system/sector by providing the necessary new pedagogical functions in a building located in the barycenter of a school district and serving all its existing facilities. The concept focuses on boosting the communication between schools in the same district and enables sharing resources between them. This non-physical connectivity will be translated into physical connectivity which bridge each existing school to the new building. The construction process fosters modularity and flexibility, allowing the project to fit the demand of different districts. The study present the results of a test of this new approach to the case study of Al Jurf 2 zone in Ajman.

Problem statement. Analysis of traditional methods for predicting the states of complex organizational and technical systems for power structures has shown that these methods are not always acceptable for solving decision support problems.Objective. Determining the causes of forecasting failures, developing a new approach to the design of decision support systems for organizational and technical systems of a particular purpose.Results. The system analysis of the class of specialized organizational and technical systems showed that the systems under consideration are non-linear. Traditional forecasting methods do not take into account the curvilinearity of systems. It is proposed to use simulation modeling, one of the staging methods, to simulate the change of system and environment states. Programs that implement simulation modeling include system software layouts and simulation programs. Simulation mockups, layouts, and simulation programs are defined in more detail. The concept of closure software is introduced. It is shown that the simulation modeling programs provide closure. The scheme of decisionmaking in competition, which is implemented by simulation modeling programs, is given.Practical implications. Examples of the use of simulation modeling in system development are given. It is shown that the used approach of simulation modeling application not only provides the software closure but also reduces the cost of creating a simulation model of the system operation and allows creating it in the process of software system development.

Ecological environments research helps to assess the impacts on forests and managing forests. The usage of novel software and hardware technologies enforces the solution of tasks related to this problem. In addition, the lack of connectivity for large data throughput raises the demand for edge-computing-based solutions towards this goal. Therefore, in this work, we evaluate the opportunity of using a Wearable edge AI concept in a forest environment. For this matter, we propose a new approach to the hardware/software co-design process. We also address the possibility of creating wearable edge AI, where the wireless personal and body area networks are platforms for building applications using edge AI. Finally, we evaluate a case study to test the possibility of performing an edge AI task in a wearable-based environment. Thus, in this work, we evaluate the system to achieve the desired task, the hardware resource and performance, and the network latency associated with each part of the process. Through this work, we validated both the design pattern review and case study. In the case study, the developed algorithms could classify diseased leaves with a circa 90% accuracy with the proposed technique in the field. This results can be reviewed in the laboratory with more modern models that reached up to 96% global accuracy. The system could also perform the desired tasks with a quality factor of 0.95, considering the usage of three devices. Finally, it detected a disease epicenter with an offset of circa 0.5 m in a 6 m × 6 m × 12 m space. These results enforce the usage of the proposed methods in the targeted environment and the proposed changes in the co-design pattern.
