Systemic Development

AbstractAs digitization progresses, the integration of information and communication technologies in technical systems is constantly increasing. Fascinating value potentials are emerging (e.g. autonomous driving), but also challenges in the system development. The constantly increasing product complexity and degree of networking require a systemic development, which is fulfilled by established approaches of Model-Based Systems Engineering (MBSE). To ensure the reliability of tomorrow's systems, an integrative and early consideration of security and safety is additionally required. In order to show the possibility and consequences of failures and attacks, the paper develops a modeling language that links established and partly isolated security and safety approaches within a consistent metamodel. The developer is enabled to synthesize system architectures transparently on an interdisciplinary level and to analyze attack and failure propagation integratively. The approach uncovers synergetic and especially contrasting goals and effects of architectural designs in terms of safety and security in order to make adequate architectural decisions based on trade-off analyses.

The course is one of the education provided outside formal (non-formal) schools to develop personal abilities and skills. Eden Everyday English Course Institute is an Institution located in Bogor. In this institution, the registration process for students is done manually by filling in the registration form provided by the admin. Eden Everyday English Course Institute is one of the courses where the number of applicants increases every year, this causes the administration department cannot manage everything properly and feels overwhelmed so that it is not effective. With the increase in the number of students registering each year, it would be better if a web-based registration system was created, so that it could simultaneously serve as a medium for promoting the course institution. The purpose of this research is to create a web-based application to help the process of registration for new students in Eden Everyday English Course Institute using the waterfall method. Many studies, especially in the field of information system development, use the Waterfall method. This online course registration application is effective and efficient because it is supported by an integrated system. This application improves the quality of information and the efficiency of the implementation of online course registration.

And Performance

Abstract An operator was developing a High-Pressure High-Temperature (HPHT) field in the U.S. Gulf of Mexico (GOM). Completion design for the injector wells was cased-and-perforated, with no mechanical sand control. This led to the requirement for a tubing-conveyed perforating (TCP) system, featuring deep-penetrating (DP) charges which would meet specific performance requirements, in order to enable the wells to achieve injectivity targets. A perforating system was therefore developed and qualified to meet these requirements. This was an integrated system development, including both mechanical and explosive components, with simultaneous attention to performance, reliability, and quality assurance in the eventual field environment. The development program yielded a 4-3/4-inch carrier system, perforating charges, firing head, and gun hanger. All key components and systems were qualified in customer-witnessed testing, and demonstrated to meet or exceed operational function and performance requirements. The pressure and temperature rating of the newly-developed system is 30,000 psi at 425 °F. Explosive train function reliability was demonstrated at 380 °F for up to 28 days. The newly-developed perforating shaped charge was confirmed to exceed the stringent penetration depth and casing hole diameter performance requirements at downhole conditions. The firing head offers operational flexibility by being configurable for up to 15 pressure cycles prior to detonation, with an adjustable initiation threshold pressure to reduce risk to the completion string. The gun hanger was customized and demonstrated to exceed load requirements, and reliably set and release, in a test configuration featuring operator-provided field casing.

Is Development

The development of information systems (IS) has for many years been regarded as the domain of the technical expert. In what appears to be a growing number of instances systems appear to be having negative effects on the organization. A regular spate of system failures may have identified serious flaws in the system development process. Organizations may often be significantly affected by the implementation of IS. Future IS development may increasingly be trans-organizational and therefore increase the potential for dysfunctionality. Even changing one line of code may have repercussions within a department/organization. To implement a totally integrated system within an organization without adequate preparation could have serious consequences for the financial well-being of the company. The development of information systems is a complex process, one with many opportunities for things to go wrong. To try and control this complex process a methodology was required that would bring more discipline to the IS development process. There is a need to make more efficient use of the resources that are available. Historically, IS has been developed using the system.development.life.cycle. (SDLC). This has been the prevailing methodology for medium and large system projects. However, the use of accepted methodologies for IS development have not guaranteed the successful implementation of information systems.

Is Integration

Worldwide, regulatory bodies are applying increasing pressure on pipeline operators to manage their pipeline systems in a safe and reliable manner. To respond to these escalating requirements, operators are developing comprehensive integrity management systems. Integrity management begins with developing strong data management capabilities to host and integrate numerous sources of physical data. A key issue in today’s integrity data management system development is integration of all pipeline data from multiple levels of the organization to one central location for easy and effective utilization of the information. Data are often scattered throughout the organization, which often tends towards data duplication, poor decisions, errors, and inefficiencies. The lack of an effective data management process leads to time and resource constrains. In the long run; development of a comprehensive integrated system has proven to be worth the investment. The primary objective of the data model is to account for a common/standard linear referencing of all pipeline features occurring along the pipeline route, and/or within the pipeline right of way. This paper describes the key factors to consider when developing a full data management system and provides some insights into how these integrated data are used to address the need for integrity management.
