МОДЕЛЬНИЙ ПІДХІД У МЕТОДОЛОГІЇ УПРАВЛІННЯ ПРОЕКТАМИ

Вступ. У деяких математичних моделях управління проектами виникає потреба встановлення максимального радіусу гіперсфери, зануреної в поліедральну галузь. Сучасний математичний апарат теорії оптимізації сумісно із застосуванням комп’ютерних технологій дає змогу розв’язувати нелінійні задачі оптимізації, але завжди існує доцільність лінеаризації складних нелінійних задач. Таке спрощення дає змогу використовувати точні класичні методи оптимізаційного розв’язку, на відміну від наближених, для нелінійної оптимізації. Поставимо завдання строгого математичного зведення (лінеаризації) багатовимірної нелінійної задачі оптимізації про занурення гіперсфери максимального радіусу в опуклу ділянку типу поліедру. Нехай маємо замкнений поліедр, поданий системою лінійних алгебраїчних нерівностей. У ділянці замкненого поліедру необхідно розмістити гіперсферу максимального радіусу. Мета. У статті проаналізовано модель установлення максимального радіусу гіперсфери, розміщеної (зануреної) у поліедральну ділянку (опуклу множину, обмежену прямими лініями), яка забезпечує врахування великої множини факторів, серед яких – управління інтеграцією (Project Integration Management); предметна ділянка проекту (Project Scope Management); управління якістю (Project Quality Management); управління часом (Project Time Management); управління вартістю (Project Cost Management); управління комунікаціями (Project Communication Management); управління контрактами (Project Procurement Management); управління ризиками (Project Risk Management). Результати. У моделі запропоновано строге математичне зведення (лінеаризація) нелінійної оптимізаційної задачі про розміщення гіперсфери максимального радіусу в опуклу ділянку типу поліедру до задачі лінійної оптимізації. Таким чином, задача про розміщення гіперсфери найбільшого радіусу в поліедрі формулюється як задача лінійної оптимізації. Висновки. Строго доведено можливість лінеаризації задачі про занурення гіперсфери максимального радіусу у поліедр. Задачу зведено до класичної задачі лінійної оптимізації, яка може бути розв’язана відомими методами. Запропонований підхід узагальнюється на задачі довільної скінченої вимірності.

Impact of integration management on performance in the UAE

Integration management is a significant factor of success in different types of organizations. Yet, the definition of integration management and ways to measure performance in a comprehensive framework need to be investigated in different environments. This paper analyzes the impact of integration management practices on company performance in the United Arab Emirates (UAE). The study uses a questionnaire that was designed with constructs and dimensions following the literature review. The components of integration management are supply chain integration, supplier integration, customer integration, knowledge transfer with customers, and managing knowledge transfer channels with customers. A questionnaire was distributed among organizations in the UAE. Statistical analysis methods were employed to analyze 94 responses, e.g. reliability tests, ANOVA, and correlation analysis. The results show that integration management improves organizational performance to a considerable degree in the UAE. The impact of these practices was positive and significant on the performance of organizations, with an average correlation coefficient of 0.81. The comprehensive assessment for integration best practices and performance and their relationship are done for the first time in the context of the UAE organizations.

Integration management – adaptive life cycle approach in solar plant construction project – experience report

The objective of this experience report was to present the solutions used in the Management Process of the Construction and Assembly project of a Solar Photovoltaic Plant in utilitarian scale, in complex, uncertain and conflicting contexts. As a leading issue, it is intended to demonstrate that new approaches adopted in the project reported here – distinct from the traditional model and practices – allowed the mitigation of the main problems common to construction projects, including divergences between executive project and field activity, delays in delivery and deadlines initially contracted, and consequent additional expenses to the base budget. As a methodology, its theoretical foundation was based on bibliographic survey, addressing aspects such as: project management and life cycle ofthem,integration between the various processes and stakeholders, and Solar Energy on a utilitarian scale, in the scope of construction. This experience report aimed to discuss and demonstrate the approach used in the Guañizuil II A project, located in Argentina, in which agility, flexibility and innovation resulted in the mitigation of delays and additional costs, the achievement of notable records and the development of practical alternatives that can be applied to other construction projects. It is concluded that engineering projects, in their executive phase, need to be aligned with reality in the field, where an adaptive approach can bring positive gains and impacts throughout the life cycle.

When Blockchain Meets the AEC Industry: Present Status, Benefits, Challenges, and Future Research Opportunities

Blockchain is regarded as a potential technology for transforming the architecture, engineering, and construction (AEC) industry, and the number of related publications is increasing rapidly. However, a systematic review of blockchain applications in the AEC industry is lacking. The objective of this study was to review the current status of blockchain applications via a bibliometric analysis combined with a systematic literature review. According to related articles collected from databases, the present status of blockchain was analysed with regard to the distribution of articles over publication years, journals, institutions, countries, cooperation networks between authors, keyword co-occurrence networks, and research methodologies. The results indicated that research on blockchain applications is still relatively new and fragmented with regard to several topics. Five areas of benefit were identified: (i) supply chain management, (ii) contract management, (iii) information management, (iv) stakeholder management, and (v) integration management. On the basis of the technology–organisation–environment framework, nine types of challenges were identified. Future research opportunities were proposed according to the research findings. This study contributes to the current body of knowledge and provides guidelines for further research on blockchain applications in the AEC industry.

Developing a Diamond Framework Model Based on “Integration” of Project Success Measures for Construction Project Management in Yemen

The most prominent obstacle facing the construction industry in Yemen is mismanagement. Developing appropriate tools, approaches, and standards for managing construction projects will contribute effectively to the development and prosperity of the Yemeni construction industry. This study aims to provide the tools, approaches and standards for project management based on the opinions of the Yemeni advisory bodies. It presents an Integrated Cost, Quality, Time, and Scope (ICQTS) diamond framework model by developing the traditional triangle model in project management providing a practical contribution to researchers and companies working in the construction industry. The study uses a descriptive and analytical approach through a comprehensive literature review followed by a field study using a designed questionnaire distributed to the relevant Yemeni advisory bodies. The study concluded with the development of the traditional triangle model resulting in the introduction of the diamond framework model in the management of construction projects. Integration management was found to have a strong impact on project success presenting the framework model as an easy and flexible tool that unifies and integrates the processes and roles in the project and directing it towards achieving project stakeholder objectives. The literature largely neglects the impact of integration management in the various models and is mostly overlooked. Inclusion of integration management in the presented model will highlight measures of project success stressing the need to integrate and manage them together. Future studies may research the differences in the opinions of construction companies.

Multi-level Governance in Refugee Housing and Integration Policy: a Model of Best Practice in Leverkusen

This paper will explore a model of best practice, the Leverkusen Model, as well as its impact on both the city and the refugees it serves by utilising key stakeholder interviews, civil servants, non-profits, and Syrian refugees living in Leverkusen. The core argument to be presented here is that the dynamic fluidity of the Leverkusen Model, where three bodies (government, Caritas, and the Refugee Council) collaborate to manage the governance responsibilities, allows for more expedited refugee integration into society. This paper utilises an analytical model of multi-level governance to demonstrate its functional processes and show why it can be considered a model of best practice. Started in 2002, the Leverkusen Model of refugee housing has not only saved the city thousands of euros per year in costs associated with refugee housing, but has aided in the cultivation of a very direct, fluid connection between government, civil society, and the refugees themselves. Leverkusen employs a different and novel governance structure of housing for refugees: with direct consultations with Caritas, the largest non-profit in Germany, as well as others, refugees who arrive in Leverkusen are allowed to search for private, decentralised housing from the moment they arrive, regardless of protection status granted by the German government. This paper fills a gap in the existing literature by addressing the adaptation of multi-level governance and collaborative governance in local refugee housing and integration management.

DAMPAK PANDEMI COVID-19 TERHADAP MANAJEMEN SEKOLAH MINGGU KOREA DI INDONESIA UNTUK PENGINTEGRASIAN PEMBELAJARAN IMAN [THE IMPACT OF THE COVID-19 PANDEMIC ON THE MANAGEMENT OF FAITH-LEARNING INTEGRATION OF KOREAN SUNDAY SCHOOL IN INDONESIA]

<p>This research is a case study that analyzes the problem of the Faith-Learning Integration management process for the Korean Sunday School “Y” in Indonesia during the COVID-19 pandemic. In this research, data collection was carried out with 5 informants, 58 questionnaires from respondents consisting of students, parents and teachers as well as recordings of student activity results. From the results of this study, it can be seen that there are several obstacles experienced by students, teachers and parents in the Faith-Learning Integration management process. First, students are not satisfied with centering on video learning platforms because there is no interaction between teachers, students and their friends so it needs to be changed from a one-way platform, such as video to an interactive platform between students and teachers such as Zoom or Google Classroom, etc. In addition, students from parents of other religions do not get support and attention from their parents to carry out Faith-Learning Integration with Work From Home (WFH) so that Faith-Learning Integration activities stop. Second, teachers' technical skills are very limited, so interactive online classroom training is required. Third, parents feel burdened and stressed when they have to give examples of faith, morals and good discipline to children in Faith-Learning Integration during WFH. The last obstacle, the 5 dimensions of the Faith-Learning Integration are not tightly integrated with each other so they do not run in harmony. The dimensions of Leitourgia and Didache were implemented well, while Kerygma, Koinonia, and Diakonia were not carried out well due to social distancing obstacles. For this reason, it is recommended that "Y" management use an interactive platform and develop innovative and creative ways that can motivate students so that they do not feel the distance between teachers and students and the surrounding environment is getting farther away even though they participate in social distancing.</p><p><strong>BAHASA INDONESIA ABSTRACT: </strong>Penelitian ini adalah studi kasus yang menganalisa masalah proses manajemen pengintegrasian pembelajaran iman Sekolah Minggu Korea “Y” di Indonesia pada masa pandemi COVID-19. Dalam penelitian ini dilaksanakan pengumpulan data dengan 5 orang narasumber, 58 hasil kuesioner dari responden yang terdiri dari siswa, orangtua dan guru serta rekaman hasil aktivitas siswa. Dari hasil penelitian ini terlihat adanya beberapa kendala yang dialami oleh siswa, guru dan orang tua dalam proses manajemen pengintegrasian pembelajaran iman. Pertama, siswa tidak puas dengan berpusat pada media pembelajaran video karena tidak terjadi interaksi antara guru, siswa dan teman-temannya sehingga perlu diubah dari media yang bersifat satu arah, seperti video ke berbagai media yang interaktif antara siswa dan guru seperti <em>Zoom</em> atau <em>Google Classroom</em>, dll. Selain itu, siswa dari orangtua yang beragama lain kurang mendapat dukungan dan perhatian dari orangtuanya untuk melakukan pengintegrasian pembelajaran iman dengan pembelajaran daring dari rumah sehingga aktivitas pengintegrasian pembelajaran iman jadi terhenti. Kedua, keterampilan teknis guru sangat terbatas sehingga diperlukan pelatihan kelas online secara interaktif. Ketiga, orangtua merasa terbebani dan stress ketika harus memberikan contoh iman, moral dan disiplin yang baik kepada anak-anak dalam pengintegrasian pembelajaran iman selama pembelajaran daring dari rumah. Kendala yang terakhir, 5 dimensi dari pengintegrasian pembelajaran iman tidak terintegrasi satu sama lain secara erat sehingga tidak berjalan selaras. Dimensi <em>Leitourgia</em> dan <em>Didache</em> dilaksanakan dengan baik, sedangkan <em>Kerygma, Koinonia</em>, dan <em>Diakonia</em> tidak terlaksana dengan baik karena adanya hambatan <em>social distancing</em>. Untuk itu disarankan manajemen “Y” menggunakan berbagai media yang interaktif dan mengembangkan cara yang inovatif dan kreatif yang dapat memotivasi siswa supaya tidak merasakan jarak antara guru dan siswa serta lingkungan sekitarnya semakin jauh walaupun mengikuti <em>social distancing</em>.</p>

Postmigrant Spatial Justice? The Case of ‘Berlin Develops New Neighbourhoods’ (BENN)

This article discusses the introduction of a new urban policy in Berlin, Germany, in the frame of postmigrant spatial justice. In 2017, Berlin established so-called ‘integration management programs’ in 20 different neighbourhoods around large refugee shelters as a response to the growing challenges local authorities faced after the administrative collapse in 2015/16. A new policy agenda provides the opportunity to learn from previous policies and programs—especially when it is addressed to the local dimension of integration, a widely and controversially discussed issue. Drawing on fieldwork conducted in Berlin in 2018 and 2019, this article discusses how migration is framed in urban social policy against both postmigrant and spatial justice theory.
