Abstract: With the rapid development of Cloud Computing and Service Oriented Computing, the process of selecting web services which gives the same functionality with different quality of service (QoS) become an important issue. To deal with the large number of Web services candidates, K-representative Skyline is appeared as a Skyline variant to find the short list of the most relevant Web services that represent a summary about the full skyline Web services result. However, it returns generally a conflicting result. To rank-order K-representative Skyline Web Services, we propose an improved Fuzzy AHP which allows to: i) elicit the QoS importance level using linguistic terms based on natural language, asking fewer efforts to users, ii) reduce the number of inputs and generate automatically all pair-wise matrix of Skyline Web services with respect to each attribute. The experimental evaluation conducted on real world dataset illustrates the feasibility and the effectiveness of our framework in comparison with existing works.

Abstract: This research shows how different educational forms such as schooling and apprenticeship are related to the development of artistic creativity from the interdisciplinary perspective based on educational anthropology of performing arts and management studies. This topic has been insufficiently explored by previous studies in both fields. More specifically, by applying the concept of schoolnization, the research compares two contrasting case studies of Chinese Qin opera and Japanese Nohgaku, based on first-hand data acquired from years of ethnographic research, to formulate a hypothesis on the ideal relationship between the enhancement of artistic creativity and process of career development. The hypothesis serves as a practical analytical framework for future research in the field.

Abstract: This article proposes an approach for transforming UML Statecharts, Sequence Diagrams and activity Diagrams to Time Petri Nets with Action Duration (DTPN) using graph transformation. By this transformation the author aims to bridge the gap between semi-formal models generated by UML and formal models DTPN. UML is considered to be the standardized language for modelling and describing systems behaviors for analysis. In other hand, DTPN models are tools for the specification and performance analysis of distributed and concurrent systems. However, the proposed approach allows to generate automatically a visual modeling tool for DTPN. The cost of building a visual modeling tool from scratch is prohibitive. Meta-modeling approach is useful to deal with this problem since it allows the modeling of the formalisms themselves, by means of graph grammars. The meta-modeling tool AToM3 is used.

Abstract: The adoption of the Business Process outsourcing strategy has been accentuated with the advent of Cloud computing that brings a new model for consuming and paying resources. Nevertheless, companies hesitate between a high distribution allowing to combine several Cloud offers adapted for process fragments and guarantee a good level of obfuscation or a weak distribution to minimize the data transfer which is charged by most suppliers and which may slow down the execution of processes. Hence, this paper proposes a novel selection method based on a heuristic algorithm that aims to find the right balance by optimizing the cost and performance while ensuring the protection of outsourced processes. To this end, several criteria are considered such as data transfer, task separation constraints and tolerated delay margins. The results obtained through a case study and comparisons with other selection methods show that the configurations selected by the algorithm meet companies’ requirements and are at the same time inexpensive, efficient and secure.

Abstract: Automatic Summarization is one of the very important tasks that are performed to improve the searching experience in the internet world. Software Repositories are one of the greatest sources of information for the software development community as it contains varied information like the team behavior, intentions, emotions, the bugs, the project style, project management information, etc. The paper is an extension to the previous work where we have used just the feature-based technique to generate the summary for the Bug Reports. Here in this paper, we have used machine-learning approaches along with the Features to find out how the results vary. For the machine learning approaches, as there are many approaches which are available, we use the very popular approaches KNN, CART, NB and SVM for the observation. We observed that when the machine learning approaches are integrated with the feature-based approach, the results improve.

Authors:Kithulwatta; W. M. C. J. T., Jayasena, K. P. N., Kumara, Banage T. G. S., Rathnayaka, R. M. K. T. Pages: 1 - 22 Abstract: Docker containerization is a newly emerging technology, which brings virtualization to software applications. Specifically, lightweight-ness has brought higher advantage for the Docker containers. Often, the deployment of distributed net centric applications on cloud hosted Docker containers is a new approach for enterprise applications. This emerging approach has been discussed on many online forums, but currently there is no secondary research study to consolidate this approach. This research study aims to identify, systematically compare and taxonomically classify the existing research studies and their practical approaches. The systematic study was conducted of fifty-seven (57) selected research studies. Selected research studies were classified and compared based on the characterization framework. The study brings the results in a discussion of emerging concerns in the Docker based deployments. Furthermore, the study is moving closer to current concerns in distributed, microservices based net centric software applications Keywords: Systems and Software Engineering; Computer Science & IT; Systems & Software Design Citation: International Journal of Systems and Service-Oriented Engineering (IJSSOE), Volume: 12, Issue: 1 (2022) Pages: 1-22 PubDate: 2022-01-01T05:00:00Z DOI: 10.4018/IJSSOE.297136 Issue No:Vol. 12, No. 1 (2022)

Authors:Seghiri; Akram, Belala, Faiza, Hameurlain, Nabil Pages: 1 - 17 Abstract: Systems of systems (SoS) are a set of independent systems that are constantly evolving. These systems cooperate in order to achieve a common goal, known as an SoS mission. It is difficult to capture their behaviours while operating in a hierarchical, cooperative and evolutionary structure. Thus, a software architecture based approach is defined in order to model and analyze these systems, reducing their increasing complexity. It ought to describe an SoS on both structural and behavioural levels. In this paper, ArchSoS, an ADL dedicated to describe SoS software architectures, is extended with a syntax-driven formal description, based on Bigraphic Reactive Systems (BRS). SoS defined via ArchSoS have both a graphical and a textual view. For this syntax to be executable, and to verify SoS evolutions, an operational semantic for ArchSoS is defined. It is implemented in Maude language to permit ArchSoS behavioural simulations, and its formal analysis is done through Linear Temporal Logic (LTL). The proposed approach is illustrated through a Crisis Response SoS as a case study.

Authors:Chan; Agnes Wai Yan, Chiu, Dickson K. W., Ho, Kevin K. W. Pages: 1 - 16 Abstract: This paper proposes a framework for career information management and guidance systems (CIMGS) to support career decision-making by providing relevant career information and recommending suitable training courses based on individuals' characteristics. A survey was conducted to collect user requirements and opinions regarding the difficulties in identifying employees' relevant career information. The findings demonstrated that users' subject knowledge at work and age affects their information-seeking behaviors, thus, the system requirements. Further, we identify three underlying factors affecting individuals' career decisions, i.e., opinions from other individuals; abilities, affections, and career plans; and personalities and family influences. The four factors that influence training decisions are information perceived, physical constraints, affections, and resources.

Authors:Raza; Zahid, Jangu, Nupur Pages: 1 - 14 Abstract: Traditional cloud-only architecture faces the challenge of coexistence with the ever-increasing IoT devices and demands for the need of the hybrid cloud computing and fog/IoT architecture to realize better handling of workload/requests. Determining where the user-workload should be assigned depends on the workload itself, and thereby, the workload classification gains the pivotal role. This location and offloading decision to the right resource affects both users and the providers. This work describes various cloud-fog workloads and relates them to their suitable place of execution in such a hybrid environment. The workloads have been classified based on their different parameters and characteristics with the aim to identify appropriate resources for efficient resource provisioning. The workload classification and characterization promises a significant role in the resource management by efficient capacity planning, future resource requirement predictions, workload offloading and an improvement in the Quality of Service (QoS) leading to an improvement in the system performance.

Authors:Nakamura; Jun, Nagayoshi, Sanetake Pages: 1 - 16 Abstract: The authors are interested in knowledge engineering for small and medium-sized enterprises (SMEs) suffering from the difficult post-COVID19 business environment. We conducted fixed-point observation using eye tracking in a production site, aiming to improve the work efficiency of industrial production. Results showed that the experts not only paid attention to a large number of points but also spent considerable attention time, moving quickly among points of attention within the constant overall work time. The number of attention points and the attention time were measured over time. The results showed a learning effect, but experts paid more attention to the critical task. Based on these findings, knowledge engineering is discussed in terms of skill transfer.
