Manufacturing System Flexibility: Product Flexibility Assessment

Meriem Lafou, Luc Mathieu, Stéphane Pois et al. · Procedia CIRP · 2016

Current manufacturing industries are experiencing a paradigm shift towards more flexibility to respond quickly and efficiently to constant changing customers’ requirements, new technologies and increasing product variety. Product flexibility is the ability of the manufacturing system to cope with the growing product variety to ensure better system performance. The aim of this paper is to point out the importance of product - resources interfaces in product flexibility assessment. Based on industrial experience, three product flexibility inductors are identified, which are gripping, setting and tooling interfaces, in order to build indicators as close as possible to real industry conditions. This research work investigates new factors to quantify product flexibility and provide manufacturing system designers with efficient decision-making support tools. In order to show the relevance of our approach, experimental results from the automotive industry are presented.

Flexibility test system.

Xi Wang (15032), Jing Xu (15337), Yuexing Zhu (669722) et al. · Figshare · 2015

<p>The specimen was fixed on the working table. Laser balls were used to simulate planes of representative vertebral bodies. An unstrained spinal 3-D motion was obtained by cables connected to loading discs. A suspended counterweight transferred equal but opposing forces on to the top of the specimen. The movement of the laser balls was tracked by six cameras hanging at different sites from the ceiling.</p>

VARIABLE FLEXIBILITY TETHER SYSTEM.

Rader,Philip J. · Defense Technical Information Center (DTIC) · 1968

The purpose of this development program was to design, fabricate, and test a prototype variable flexibility tether system, which by virtue of its controllable rigidity and remotely actuated manipulator, may be used as a simple safety tether, a translation aid, an astronaut attachment and positioning tool and a means of moving and recovering objects in space.

Distribution System Operation: Flexibility Services

Aithal, Avinash, Wainwright, Andrew, Atkins, Steve · 2025

This open access book is a coherent and accessible source of knowledge on flexibility services for energy. Local flexibility services are a commercial mechanism which allows participants to be renumerated for delivering a change in their usual power use, in real time or in response to prior request from the Distribution System Operators (DSOs) to help manage network congestion. Summarising key outputs from the Energy Networks Association’s (ENA) Open Networks Programme, the book traces the evolution of local flexibility markets from 'Proof of Concept' to 'Business as Usual'. The book presents detailed technical and organisational insights from the development of local flexibility markets, focusing on inception, standardization, simplification, and transparency in decision-making across GB DSOs and interactions with the National Energy System Operator (NESO). Readers will find valuable comparisons of implementation approaches by different network companies, highlighting technical nuances and best practices. Ideal for researchers, energy professionals, and policymakers, this book provides a critical resource for understanding the complexities and opportunities of flexibility services in energy systems. Whether you are involved in energy management, policy development, or academic research, this book offers essential insights into the future of energy flexibility and grid management.

Controllled flexibility in system design

Allen Brady Montz, Larry Peterson · 1998

Historically, applications have been distributed in order to access more resources than a lone machine could supply, such as CPU power, disks, or the computers themselves (for fault tolerance). We are increasingly seeing applications which are distributed because they are meant to be used by multiple people, and multiple people generally have multiple machines. These applications are distributed by definition. A good example of this is a distributed multimedia application such as multicast video, email, or the World Wide Web. It is well understood how the interaction of software with people.makes the software more complicated; we are entering the realm of software which exists purely to glue people together.

Evaluation of Power System Flexibility

Eamonn Lannoye, Damian Flynn, Mark O’Malley · IEEE Transactions on Power Systems · 2012

As the penetration of variable renewable generation increases in power systems worldwide, planning for the effects of variability will become more important. Traditional capacity adequacy planning techniques have been supplemented with integration studies, which have been carried out in power systems with high targets for renewable generation. These have highlighted the increased variability that a system may experience in the future. As system generation planning techniques evolve with the challenge of integrating variable generation, the flexibility of a system to manage periods of high variability needs to be assessed. The insufficient ramping resource expectation (IRRE) metric is proposed to measure power system flexibility for use in long-term planning, and is derived from traditional generation adequacy metrics. Compared to existing generation adequacy metrics, flexibility assessment is more data intensive. A flexibility metric can identify the time intervals over which a system is most likely to face a shortage of flexible resources, and can measure the relative impact of changing operational policies and the addition of flexible resources. The flexibility of a test system with increasing penetrations of variable generation is assessed. The results highlight the time horizons of increased and decreased risk associated with the integration of VG.

Power system load flexibility forecasting

Şahika Genç · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023

The example embodiments are directed to a system and method for forecasting load flexibility of a power grid. In one example, the method includes receiving temperature values associated with temperature set points of a plurality of loads that are included on a power grid, forecasting a flexibility of the plurality of loads using a polynomial-time mixed-integer non-linear programming (MINLP) optimization based on the received temperature values for the plurality of loads, and outputting information about the forecasted flexibility for display to a display device. The MINLP optimization performs the forecasting of the load flexibility on a fine-grained basis in comparison to conventional methods and is still fast enough that it can be computed in real-time.

"Test System for Energy Flexibility "

Amjad Anvari Moghaddam · IEEE DataPort · 2025

"With the increasing integration of renewable energy and the resulting uncertainty in power generation, system flexibility has become more important than ever. Energy flexibility- an essential component of overall system flexibility- requires long-term studies, often spanning a year or more. However, a major challenge is the lack of well-structured, long-term consumer data for energy districts. Detailed disaggregated profiles are rarely available, as many consumers are unwilling to share such data, and most existing datasets provide only aggregated annual values. At the same time, the growth of multi-energy carrier systems has created a need for test systems that support long-term analysis across multiple carriers. To address this gap, we compiled and processed data from several references to develop a test system integrating electricity and heat. It represents an energy district with three household profiles, three heating profiles, electric vehicles, office buildings, and warehouses. The resulting one-year dataset is user-friendly, comprehensive, and suitable for a wide range of energy flexibility studies."
