This paper documents a system improvement study conducted by Atlantic Electric (AE) Company using EPRI's reliability analytical tools. With increased emphasis on customer service, reliability and cost control, AE is striving to balance the value of supply reliability to its customers with the costs of system improvement. The paper presents a dollar value quantification of the level of reliability inherent in a given system improvement option.Based on this quantification, the improvement option that best balance the improvement cost and the incremental reliability is selected. Reliability indices including the expected unserved energy (EUE) were computed for each improvement option. Using the EUE, the value of service un-reliability to the customers was computed for each option. Dollar value based analysis is then performed to balance cost and reliability quantitatively. A selection process that a utility engineer or system planner may go through to arrive at the option that best balance the cost and reliability of system improvement is covered in the paper.
Digitalization changes the way people work to a considerable extent. It alters business models and process organizations of whole industries. The ensuing market dynamics and faster innovation cycles cause an increase in complexity. In this article, the interconnection of digitalization and complexity in work systems is analyzed. For this purpose, a framework for comparing relevant complexity definitions is developed. Moreover, complexity drivers in digitalized labor systems in six different organizational dimensions (process organization, organizational structure, technology, working conditions, product and personnel) are explored. 23 experts from the academic and industrial sector were interviewed using semi-structured interviews. The results of a qualitative content analysis show that the consideration of complexity and digitalization has extensive impact what becomes evident in interdependent relations amongst the organizational dimensions. Furthermore, complexity drivers in digitalized work systems are determined as a result of the analysis procedure. Finally, the implications of the expert interviews for cooperative forms of work are discussed. The concept of a "task complexity mountain range" is presented to explain the effect of task complexity on performance and motivation in the context of work groups.
Individuelle Produkte, komplexe Prozesse und hohe Produktivitäts- und Flexibilitätsanforderungen - Bedingungen, die viele Unternehmen vor große Herausforderungen bei der Planung ihrer Produktionssysteme stellen. Simulationsverfahren können hierbei unterstützen, in der Praxis sind allerdings diverse Hürden zu überwinden. Am Beispiel einer simulationsbasierten Optimierung der Maschinenbelegungsplanung des Presswerks eines Herstellers weißer Ware werden mögliche Lösungsansätze demonstriert.*)
ZusammenfassungProjekt- und Teamarbeit sind in der betrieblichen Praxis etabliert und bestimmen die Arbeits- und Belastungssituation vieler Beschäftigter. Als Formen kooperativer und flexibler Arbeitsorganisation besitzen sie durchaus Potenziale, die Herausforderungen dynamischer und komplexer Arbeitswelten zu bewältigen. Mit den technologischen, marktökonomischen und gesellschaftlichen Veränderungen ändern sich allerdings auch die Bedingungen, unter denen Projekt- und Teamarbeit heute stattfindet. Im Beitrag werden einige wesentliche Entwicklungslinien von Projekt- und Teamarbeit skizziert, um darauf aufbauend zentrale Herausforderungen zu benennen, vor denen die Arbeitsgestaltung heute steht. Diese Herausforderungen waren Gegenstand der Forschung einer themenspezifischen Schwerpunktgruppe im BMBF-Förderschwerpunkt „Arbeit in der digitalisierten Welt“. Der Beitrag schließt mit einem Überblick über den Sammelband, der die Ergebnisse dieser Schwerpunktgruppe bündelt.
