Gaps and requirements for applying automatic architectural design to building renovation

The renovation of existing buildings provides an opportunity to change the layout to meet the needs of facilities and accomplish sustainability in the built environment at high utilisation rates and low cost. However, building renovation design is complex, and completing architectural design schemes manually needs more efficiency and overall robustness. With the use of computational optimisation, automatic architectural design (AAD) can efficiently assist in building renovation through decision-making based on performance evaluation. This paper comprehensively analyses AAD's current research status and provides a state-of-the-art overview of applying AAD technology to building renovation. Besides, gaps and requirements of using AAD for building renovation are explored from quantitative and qualitative aspects, providing ideas for future research. The research shows that there is still much work to be done to apply AAD to building renovation, including quickly obtaining input data, expanding optimisation topics, selecting design methods, and improving workflow and efficiency

Achieving manufacturing excellence through the integration of enterprise systems and simulation

This paper discusses the significance of the enterprise systems and simulation integration in improving shop floor’s short-term production planning capability. The ultimate objectives are to identify the integration protocols, optimisation parameters and critical design artefacts, thereby identifying key ‘ingredients’ that help in setting out a future research agenda in pursuit of optimum decision-making at the shop floor level. While the integration of enterprise systems and simulation gains a widespread agreement within the existing work, the optimality, scalability and flexibility of the schedules remained unanswered. Furthermore, there seems to be no commonality or pattern as to how many core modules are required to enable such a flexible and scalable integration. Nevertheless, the objective of such integration remains clear, i.e. to achieve an optimum total production time, lead time, cycle time, production release rates and cost. The issues presently faced by existing enterprise systems (ES), if properly addressed, can contribute to the achievement of manufacturing excellence and can help identify the building blocks for the software architectural platform enabling the integration

10. Interuniversitäres Doktorandenseminar Wirtschaftsinformatik Juli 2009

Begonnen im Jahr 2000, ist das Interuniversitäre Wirtschaftsinformatik-Doktorandenseminar mittlerweile zu einer schönen Tradition geworden. Zunächst unter Beteiligung der Universitäten Leipzig und Halle-Wittenberg gestartet. Seit 2003 wird das Seminar zusammen mit der Jenaer Universität durchgeführt, in diesem Jahr sind erstmals auch die Technische Universität Dresden und die TU Bergakademie Freiberg dabei. Ziel der Interuniversitären Doktorandenseminare ist der über die eigenen Institutsgrenzen hinausgehende Gedankenaustausch zu aktuellen, in Promotionsprojekten behandelten Forschungsthemen. Indem der Schwerpunkt der Vorträge auch auf das Forschungsdesign gelegt wird, bietet sich allen Doktoranden die Möglichkeit, bereits in einer frühen Phase ihrer Arbeit wichtige Hinweise und Anregungen aus einem breiten Hörerspektrum zu bekommen. In den vorliegenden Research Papers sind elf Beiträge zum diesjährigen Doktorandenseminar in Jena enthalten. Sie stecken ein weites Feld ab - vom Data Mining und Wissensmanagement über die Unterstützung von Prozessen in Unternehmen bis hin zur RFID-Technologie. Die Wirtschaftsinformatik als typische Bindestrich-Informatik hat den Ruf einer thematischen Breite. Die Dissertationsprojekte aus fünf Universitäten belegen dies eindrucksvoll.

Automatische Generierung eines Simulationsmodells zur Unterstützung der Umplanung einer Baustellenmontage

Fixed-Layout Assembly (FLA) systems are used to assemble large and bulky products. These products are often unique and require customer-specific engineering and customization. FLA systems are frequently prone to disturbances and plan deviations throughout operations: delayed deliveries, incompatibility or failures of equipment, and unplanned absences of operators. Planners therefore need a simple and efficient tool to quickly forecast the impact of changes on the whole assembly system. A solution concept has been presented by the authors in a previous publication (Billiet and Stark, 2022). The authors presented a method to automatically generate a simulation model by using data concerning the products, orders and shifts from the ERP system. This paper describes the implementation of the previously presented solution concept by applying it to a FLA for the production of Large Motors and Converters (LMC) in Berlin

Designing an Open Virtual Factory of Small and Medium-sized Enterprises for Industrial Engineering Education

Curriculum of Industrial Engineering program must accomplish the requirement that graduates have the ability to design, develop, implement, and improve integrated system that include people, materials, equipment and energy. However, it is not easy to implement a curriculum that fosters such competencies. One of the strategies to achieve that is using an innovative learning media, so that the problem-based learning (PBL) can be accustomed. In this paper, we design a web-based enterprise resources planning. It is aimed to capture the real problem of small and medium-sized enterprises (SMEs) in bottled drinking water industries. The integrated system can be illustrated as ERP application that designed by using free open source software (FOSS). This research aimed to utilize the application to improve teaching methods in IE education. The result of the research can be used to improve the competencies of IE students, especially the abilities to identify, formulate, and solve the activities of the business process improvement in SMEs. Keywords Industrial engineering education, FOSS, innovative learning media, problem-based learnin

Digital Supply Chain Twins in Urban Logistics System – Conception of an Integrative Platform

Current trends in urban areas pose several challenges to city logistics stakeholders while also offering opportunities for optimization. With its analytics, modelling and simulation capabilities, the Digital Supply Chain Twin (DSCT) technology provides a possibility to optimize urban logistics processes. However, a number of barriers have limited the implementation of holistic DSCTs so far. An integrative, collaborative platform could decrease these barriers. By applying design science research methodology and expert interviews, this paper develops an architecture for a high-level cross-institutional platform for the generation of DSCTs. This framework includes a modular design of the platform through eight functional modules. The platform can facilitate the implementation of DSCTs for urban stakeholders and thus optimize urban logistics processes
