Sistem Informasi Kerja Praktek dan Tugas Akhir Program Studi Sistem Komputer

Information technology development today resulted in the growing number of internet users. Easy access of the internet makes it as a media presentation of data to both individuals and institutions. It is similar with Computer System major that has taken advantage of the Internet to provide a variety of information to both academic and community service in the field of information technology. But it is still using manual method to organize and inventory data associated with the On-Job Training (KP) and Final Project (TA) in a site. One way to ease the data organization is to design an information system that can record and organize all the data held by the Computer System. Design and Implementation phase begins with system requirement analysis. Its objection is to get a proper system specification. In design phase, Data Flow Diagram is used to represent data in a logic way. The result from design phase then implements with PHP programming language, associated with Database Management System MySQL, and Javascript to generate a dynamic web-based information system. The previous research “Perancangan Sistem Informasi Seminar dan Tugas Akhir Mahasiswa Jurusan Teknik Elektro Undip” was to organize database final project consist of schedule, seminar schedule, and test schedule. It used Unified Modeling Language (UML) consist of use case and activity diagram. The users of this information system were two, that were called admin and student. The result from information testing showed that all features like organizing students data, organizing teacher data, printing KP and TA data, uploading KP and TA data, alerting KP and TA coordinator about the schedule of the students worked well. The current research use Entity Relationship Diagram model system. This information system has five users, that are admin, student, teacher, KP coordinator, and TA coordinator.

UML을 이용한 GIS기반 새만금 DIPSDRM 공법 모바일 관리 시스템 설계 및 구현

The world largest land reclamation project in the name of Saemangeum(Ariul) from 1991 to the present has been implementing in a part of the west coast of Korea. In the Saemangeum reclamation project, the large-scale project cost is used for the landfill reclamation. A number of landfill reclamation methods have been studied in order to reduce the large-scale cost of the Saemangeum project under construction. There are many studies related to the on-site real-time monitoring with mobile systems for operating a wide range of landfill. In order to apply the work method for efficient cost-savings in the landfill operations to the Samangeum project, this paper develops a mobile management system that is composed of a mobile interface module, a data server module for data transmission and storage, and an analysis server module to analyze the input data and derive the results. The mobile system is designed by analysing user`s and system requirements, functional interactions, and data flow using unified modeling language(UML). The user interface is developed for the on-site real-time monitoring through the status and related attributes of land reclamation by using the digital maps of the Samangeum coverage via mobile devices. Finally, a mobile management system would be developed that can provide a 3D GIS service based on the Dry Internal Project Site Digging Reclamation Method(DIPSDRM).

Extending the UML use case metamodel with behavioral information to facilitate model analysis and interchange

Use case diagrams are primary artifacts used for modeling functional requirements. Use case diagrams are part of the Unified Modeling Language (UML) suite of models that has become a de facto standard for modeling object oriented languages. Each model in this suite is described by a metamodel that dictates its syntax and semantics. The use case diagram is considered the most controversial diagram in UML. Practitioners claim that the use case diagram cannot be used as a valuable artifact for requirement analysis. The main reason behind this concern is the lack of behavioral description of a use case depicted within the model. Quite a few extensions to the use case metamodel have been proposed in literature to incorporate behavioral aspect of a use case within the metamodel. All these extensions omit a few important features like generalization and most of them can only be used for model representation and cannot be used for model analysis and evaluation. In this paper, we propose an extension to the UML use case metamodel with use case behavior specification elements. The main objective of the proposed extension is to provide a complete metamodel for use case diagrams which includes representation for all its elements and relationships in a conflict-free manner and one that includes information for model analysis, evaluation, and interchange among modeling tools. In order to include all valuable information related to a use case, a number of use case representation templates were considered for the proposed extension. Simultaneously, to enable the use case models generated based on the proposed metamodel to be used for analysis, pertinent information related to model usage in analysis such as effort estimation, use case scheduling, and use case metrics evaluation were considered from published studies, tools, and paradigms and included within the proposed metamodel.

Experimental development based on mapping rule between requirements analysis model and web framework specific design model

Model Driven Development is a promising approach to develop high quality software systems. We have proposed a method of model-driven requirements analysis using Unified Modeling Language (UML). The main feature of our method is to automatically generate a Web user interface prototype from UML requirements analysis model so that we can confirm validity of input/output data for each page and page transition on the system by directly operating the prototype. We proposes a mapping rule in which design information independent of each web application framework implementation is defined based on the requirements analysis model, so as to improve the traceability to the final product from the valid requirements analysis model. This paper discusses the result of applying our method to the development of a Group Work Support System that is currently running in our department.

A novel approach for supporting the development cycle of automation systems

The growing complexity of current automation applications demand clear methodologies and procedures in order to assure that the system under design meets the requirements. Within the industrial automation field there are several methods, techniques, tools and standards that have captured the experience of designers through years of practice. On the other hand, the software engineering discipline offers different methodologies covering the different phases of the life cycle (analysis, design, test and maintenance). This work pretends to take advantage of both: the maturity of the software engineering discipline and the well-spread methods and standards of the industrial automation field. In particular, the proposed methodological approach uses model based engineering principles for developing automation control systems combining modeling methods of automation field. Specifically, it combines GEMMA (Guide d'Etude des Modes de Marches et d'Arrets), UML (Unified Modeling Language) use case diagrams and GRAFCET (GRAphe Fonctionnel de Commande, Etapes, Transitions) for assisting the designer during the analysis, design and coding phases. Using GEMMA, the states of the automated process are identified. Use case diagrams allow identifying the actors that participate in the operation modes. Finally, a set of GRAFCET templates assists in the design of use cases. Thus, the user is guided through the development phases in which the concepts used are familiar to him/her. The final step includes the automatic generation of the Program Organization Units (POUs) in PLCopen XML interface. The proposed methodology is illustrated by means of a simple but illustrative mechatronic case study.

An object-oriented model to support healthcare facility information management

Facility management within healthcare is required to ensure that complex systems are maintained and operational while causing minimum interruption to clinical activities and maintaining patient safety. Their tasks are complicated by fragmented and sometimes incomplete information. To help facility managers better manage lifecycle information pertinent to managing the facility and responding to facility related patient safety events, an object oriented product model is proposed in the context of developing a healthcare facility information management framework. The product model is developed as a result of various case analyses that were conducted using Unified Modeling Language (UML) Use Cases to examine information needs for existing healthcare facility maintenance operations. The resulting classification system and its uses to respond to patient safety events are discussed in this paper.

Dynamical and Mechanistic Reconstructive Approaches of T Lymphocyte Dynamics: Using Visual Modeling Languages to Bridge the Gap between Immunologists, Theoreticians, and Programmers

Dynamic modeling of lymphocyte behavior has primarily been based on populations based differential equations or on cellular agents moving in space and interacting each other. The final steps of this modeling effort are expressed in a code written in a programing language. On account of the complete lack of standardization of the different steps to proceed, we have to deplore poor communication and sharing between experimentalists, theoreticians and programmers. The adoption of diagrammatic visual computer language should however greatly help the immunologists to better communicate, to more easily identify the models similarities and facilitate the reuse and extension of existing software models. Since immunologists often conceptualize the dynamical evolution of immune systems in terms of “state-transitions” of biological objects, we promote the use of unified modeling language (UML) state-transition diagram. To demonstrate the feasibility of this approach, we present a UML refactoring of two published models on thymocyte differentiation. Originally built with different modeling strategies, a mathematical ordinary differential equation-based model and a cellular automata model, the two models are now in the same visual formalism and can be compared.

Research on the MIS of Product Drawing Based on UML

Around the development process of product drawing management system, a model is established by making use of unified modeling language (UML). The whole process from function analysis system design and physics model design and system development is described by a series of diagrams. The model makes a complex command system expressed in plain and visual graphics; it provides the valid path to the MIS of product drawing system.

Secured Workstation to Process the Data of Different Classification Levels

The paper presents some of the results obtained within the ongoing project related with functional requirements and design models of secure workstation for special applications (SWSA). SWSA project is directed toward the combination of the existing hardware and software virtualization with cryptography and identification technologies to ensure the security of multilevel classified data by means of some formal methods. In the paper the requirements for SWSA, its hardware and software architecture, selected security solution for data processing and utilized approach to designing secure software are presented. The novel method for secure software design employs dedicated tools to verify the confidentiality and the integrity of data using Unified Modeling Language (UML) models. In general, the UML security models are embedded in and simulated with the system architecture models, thus the security problems in SWSA can be detected early during the software design. The application of UML topology models enables also to verify the fundamental requirement for MLS systems, namely the hardware isolation of subjects from different security domains.

Business Process Modelling is an Essential Part of a Requirements Analysis

To perform a requirements analysis of the barriers to conducting research linking of primary care, genetic and cancer data. We extended our initial data-centric approach to include socio-cultural and business requirements. We created reference models of core data requirements common to most studies using unified modelling language (UML), dataflow diagrams (DFD) and business process modelling notation (BPMN). We conducted a stakeholder analysis and constructed DFD and UML diagrams for use cases based on simulated research studies. We used research output as a sensitivity analysis. Differences between the reference model and use cases identified study specific data requirements. The stakeholder analysis identified: tensions, changes in specification, some indifference from data providers and enthusiastic informaticians urging inclusion of socio-cultural context. We identified requirements to collect information at three levels: micro- data items, which need to be semantically interoperable, meso- the medical record and data extraction, and macro- the health system and socio-cultural issues. BPMN clarified complex business requirements among data providers and vendors; and additional geographical requirements for patients to be represented in both linked datasets. High quality research output was the norm for most repositories. Reference models provide high-level schemata of the core data requirements. However, business requirements' modelling identifies stakeholder issues and identifies what needs to be addressed to enable participation.

An online information system to support blended training of rural SMEs on e‐government

PurposeAway from central public authorities, regional (also called rural) enterprises do not have direct, physical access to all the services that governmental or public agencies offer. Very often, these services are essential for enterprises, mostly small and medium‐sized enterprises (SMEs), in such areas, in order to perform their business operations. This paper aims to present an example of how such types of information management and use took place in the case of familiarizing rural SMEs with the use of e‐government.Design/methodology/approachThis paper is a case study of how a practical application is designed and developed for the blended training of rural SMEs. First of all, an identification of the main information resources that will be stored, annotated, shared and accessed through the system took place. Then, an outline of the general architecture and user roles involved was developed. System analysis and specification using Unified Modeling Language (UML) then took place. This was accompanied by design and specification of the database, based on appropriate metadata schemas for describing the information resources. The whole process was completed by the design and prototype development of the interface, which was put into public operation and testing with a sample set of real users.FindingsAlthough there are several information management systems focusing on the education and training of rural stakeholders, their learning resources are not directly relevant to SMEs' needs. The main finding of this paper is that it shows a complete case study of designing, developing and evaluating an information technology application for rural businesses.Originality/valueThe value of the approach presented here is the combination of training resources in an information system with a blended training approach, so that it better matches the learning needs of SMEs. Through this web‐based environment, rural SMEs are able to find information on the e‐government services offered in their region, as well as gaining access to e‐learning content on how they can use such services.

Extensión y Aplicación de AspectZ a la Administración de un Sistema de Fichas de Salud Electrónicas en Chile

This paper presents an extension of AspectZ to model the requirements of software that manages a system of electronic health records in Chile: SYSFIC 1.0. AspectZ is an aspect-oriented language that preserves the basic characteristics of language Z and that aims to encapsulate cross-cutting concerns of a system into separate and independent entities. The application includes the use of Unified Modeling Language (UML) diagrams and a formal modeling of the system using AspectZ. The main features of the aspect-oriented modeling paradigm, such as the separation of concerns and the reduction and elimination of scattered and tangled code, are discussed. The results of this study show that the combination of aspect-oriented modeling and a formal method of software development allow obtaining more reliable solutions for critical information systems such as SYSFIC.

Conceptualization in ideational theory of meaning: Cognitive theories and semantic modeling

The ideational theory of meaning is the theory according to which meanings of words are subjective ideas. In this article, we propose a visual modeling using Unified Modeling Language (UML) which, we believe, clearly represents the semantic of this theory. Additionally, we modify and extend classic ideational theory to provide answers to some of its defects, for instance, second-order concepts. We will show that our modeling is compatible with the cognitive theories about conceptualization such as hierarchical, network and prototype theory.

Maximizing the Profit of Telecom Telcos by a Novel Traffic Scheduling Policy

This paper introduces a novel traffic scheduling policy whose objectives is to maximize the profit of telecom telcos.Telecommunication network management is reconsidered from the business point of view, introducing competition between users forresources of the telecom telcos, in addition to existing competition between telcos themselves. Business control of network is supportedby loop back control that should be realized as on-line technology supplied with intelligent control algorithms. The results odsimulation, obtained through extensive testing, prove the correctness of proposed method for optimizing telco profit and show that,neither pure E nor pure L policy, can give the maximum profit. To specify and implement the proposed system we use unified modelinglanguage (UML).

UXSOM

Software developers are increasingly using Unified Modeling Language (UML) tools to automate source code generation. Therefore, nowadays calculating software metrics from UML diagrams to evaluate software quality is an important trend in the software industry. However, acquisition of software metrics from Extensible Markup Language (XML) export of UML tools has been predominantly tool dependent. Moreover, each new tool may have different specifications in XML. Despite the overall need for a process to automate XML unification, no current solution has yet been proposed. Creating a framework to automate this assessment would streamline development and increase efficiency in software industry. With the aim to overcome this deficiency, we developed a parser-based framework, named UXSOM, to calculate software metrics independently from the UML tool. Particularly UXSOM is able to generate software metrics from the XML-based outputs of the tools, ArgoUML, UMLET, MagicDraw, Sparx Systems, and ESS Model. We showed a very general case of UML class diagram, in which we extracted and compared software metrics from these five different tool.

Visualizing and Assessing a Compositional Approach to Service-Oriented Business Process Design Using Unified Modelling Language (UML)

In the context of Service-Oriented Architecture (SOA), complex systems can be realized through the visualization of business driven processes. The automation of Service Supported Systems (SSS) is the future integral part of core SOA which provides preprocessed information and solution suggestions for the Cloud Computing Users (CCU). CCU requires compact and fast decision supporting displays and user interface in order to handle the increasing work load. This requires intelligent, intuitive and robust preprocessing system as a backbone for automation lifecycle management. Complex business management processes often entail complex environmental decision-making procedures. This process can be greatly enhanced if it is based on an exploratory-envisioning system such as Information Exploration and Visualization Environment. Current scientific research has taken advantage of e-science to enhance distributed simulation, analysis and visualization. Many of these infrastructures use one or more collaborative software paradigms like Grid Computing, High Level Architecture (HLA) and Service Oriented Architecture (SOA), which together provide an optimal environment for heterogeneous and distant, real-time collaboration. While significant progress has been made using these collaborative platforms, often there is no particular software suite that fulfils all requirements for an entire organization or case study. End-user must cope manually with a collection of tools and its exporting/importing capabilities to obtain the output needed for a particular purpose. We presents how service oriented architecture can be utilized in automation services support system using RCD framework as underlying composition platform. The introduced framework combines rapid analysis development and intelligent process state visualization for CCU and discusses the challenges met in building reliable cloud computing services for web services. Unified Modeling Language (UML) is used as a specification technique for the system analysis and design process which is the only way to visualize one’s design and check it against requirements before developers start to code.

Improving tests infrastructure through a model-based approach

Software tests have a high impact on the cost of software development. In practice, they are generally created at random and without any methodology, and do not have sufficient documentation. Commonly used approaches also perform the tests outside the application environment (e.g. web servers and containers). Besides, the test cases are usually restricted to target business components behavior, leaving a huge gap by not evaluating the presentation layer. Most of these practices can be explained by the overhead required to maintain manually the whole test artifacts. Applying a Model-based Approach (MBA), the creation and maintenance of test artifacts can be automated. This paper proposes a method that applies the Model-driven Architecture (MDA), a strategy of MBA, to determine the flow of test cases. The proposed method was based on the use of Unified Modeling Language (UML) activity diagrams. These diagrams allow determining the test flows and the objective of each activity, such as testing of business and presentation layers. Moreover, the generated test artifacts allow for performing the tests inside the application environment.

Implementation and evaluation of a queuing systems modelling course using Unified Modelling Language (UML)

In this paper, we present a new approach in the way that a network modelling and simulation or a queuing theory course can be done. Beyond the mathematical model that sometimes is too difficult for students to understand, this paper introduces the use of Unified Modelling Language (UML) as the mean to teach modelling of discrete event systems such as queues and networks. The basic course scheduling and teaching material are presented too. It is also shown how this method was evaluated by the teachers and the students that attended the course and answered a questionnaire.

Enterprisewide Information Management System for Transportation Right-of-Way Activities

Given the current state of technology–with service-oriented architecture, decentralized information, and desktop access to cloud computing and data management–enterprise systems for managing the information associated with business operations are necessary for improving efficiency and quality while optimizing resources. In transportation agencies, this situation is particularly true in the data-intense real estate offices that purchase and manage right-of-way property before construction. A structure is presented for a logical model of an enterprisewide information management system for transportation right-of-way activities. The business processes are based on the federal requirements as mandated by law and outlined in the Project Development Guide of FHWA's Office of Real Estate Services for appraisal, acquisition, relocation, and property management. The logical model is developed with the use of unified modeling language, which is considered to be a standard computer system modeling language rich in well-defined graphical notations for representing complex systems and provides the structure for developing an operational information management software program.
