Download or read book Assembly Line Balancing under Uncertain Task Time and Demand Volatility written by Yuchen Li and published by Springer Nature. This book was released on 2022-09-10 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces several mathematical models in assembly line balancing based on stochastic programming and develops exact and heuristic methods to solve them. An assembly line system is a manufacturing process in which parts are added in sequence from workstation to workstation until the final assembly is produced. In an assembly line balancing problem, tasks belonging to different product models are allocated to workstations according to their processing times and precedence relationships among tasks. It incorporates two features, uncertain task times, and demand volatility, separately and simultaneously, into the conventional assembly line balancing model. A real-life case study related to the mask production during the COVID-19 pandemic is presented to illustrate the application of the proposed framework and methodology. The book is intended for graduate students who are interested in combinatorial optimizations in manufacturing with uncertain input.

Download or read book Balancing and Sequencing of Assembly Lines written by Armin Scholl and published by Physica. This book was released on 1999-02-26 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with two main decision problems which arise when flow-line production systems are installed and operated. The assembly line balancing problem consists of partitioning the work, necessary to assemble the product(s), among different stations of an assembly line. If several models of a product are jointly processed on a line, this medium-term problem is connected with the short-term problem of determining an operating sequence of the models. In Part I balancing and sequencing problems are discussed, classified, and arranged within a hierarchical planning system. In the present second edition special emphasis is given to u-shaped assembly lines which are important components of modern just-in-time production systems. Part II is concerned with exact and heuristic procedures for solving those decision problems. For each problem type considered, a survey of existing procedures is given and new efficient solution methods are developed. Comprehensive numerical investigations showing the effectiveness of the new methods and their superiority over existing approaches are reported.

Download or read book Energy Efficiency in Manufacturing Systems written by Sebastian Thiede and published by Springer Science & Business Media. This book was released on 2012-04-23 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy consumption is of great interest to manufacturing companies. Beyond considering individual processes and machines, the perspective on process chains and factories as a whole holds major potentials for energy efficiency improvements. To exploit these potentials, dynamic interactions of different processes as well as auxiliary equipment (e.g. compressed air generation) need to be taken into account. In addition, planning and controlling manufacturing systems require balancing technical, economic and environmental objectives. Therefore, an innovative and comprehensive methodology – with a generic energy flow-oriented manufacturing simulation environment as a core element – is developed and embedded into a step-by-step application cycle. The concept is applied in its entirety to a wide range of case studies such as aluminium die casting, weaving mills, and printed circuit board assembly in order to demonstrate the broad applicability and the benefits that can be achieved.

Download or read book Rwanda written by International Monetary Fund. African Dept. and published by International Monetary Fund. This book was released on 2022-12-19 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supported by a large policy package, Rwanda’s economy rebounded in 2021 after contracting in the preceding year due to the COVID-19 shock. However, the country now faces multi-faceted challenges—pandemic scars, headwinds from the war in Ukraine, and climate-related shocks, meanwhile inflationary pressures have increased markedly. Downside risks are significant from the war spillovers, through further pressures on energy, food, and fertilizer prices, global financial tightening, and slowdown in major trading partners, in addition to climate-related shocks. Against this backdrop, the authorities have requested a new Policy Coordination Instrument (PCI) and an arrangement under the Resilience and Sustainability Facility (RSF) to support their efforts in maintaining macroeconomic stability, advancing their reform agenda, including on climate to enhance Rwanda’s resilience to climate-related shocks, and insuring against downside risks. They will cancel the current PCI (expiring in June 2023) upon approval of the new PCI.
Download or read book Managing in a VUCA World written by Oliver Mack and published by Springer. This book was released on 2015-07-15 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines volatility, uncertainty, complexity and ambiguity (VUCA) and addresses the need for broader knowledge and application of new concepts and frameworks to deal with unpredictable and rapid changing situations. The premises of VUCA can shape all aspects of an organization. To cover all areas, the book is divided into six sections. Section 1 acts as an introduction to VUCA and complexity. It reviews ways to manage complexity, while providing examples for tools and approaches that can be applied. The main focus of Section 2 is on leadership, strategy and planning. The chapters in this section create new approaches to handle VUCA environments pertaining to these areas including using the Tetralemma logics, tools from systemic structural constellation (SySt) approach of psychotherapy and organizational development, to provide new ideas for the management of large strategic programs in organizations. Section 3 considers how marketing and sales are affected by VUCA, from social media’s influence to customer value management. Operations and cost management are highlighted in Section 4. This section covers VUCA challenges within global supply chains and decision-oriented controlling. In Section 5 organizational structure and process management are showcased, while Section 6 is dedicated to addressing the effects of VUCA in IT, technology and data management. The VUCA forces present businesses with the need to move from linear modes of thought to problem solving with synthetic and simultaneous thinking. This book should help to provide some starting points and ideas to deal with the next era. It should not be understood as the end of the road, but as the beginning of a journey exploring and developing new concepts for a new way of management.

Download or read book Decision Making Under Uncertainty written by Mykel J. Kochenderfer and published by MIT Press. This book was released on 2015-07-24 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to decision making under uncertainty from a computational perspective, covering both theory and applications ranging from speech recognition to airborne collision avoidance. Many important problems involve decision making under uncertainty—that is, choosing actions based on often imperfect observations, with unknown outcomes. Designers of automated decision support systems must take into account the various sources of uncertainty while balancing the multiple objectives of the system. This book provides an introduction to the challenges of decision making under uncertainty from a computational perspective. It presents both the theory behind decision making models and algorithms and a collection of example applications that range from speech recognition to aircraft collision avoidance. Focusing on two methods for designing decision agents, planning and reinforcement learning, the book covers probabilistic models, introducing Bayesian networks as a graphical model that captures probabilistic relationships between variables; utility theory as a framework for understanding optimal decision making under uncertainty; Markov decision processes as a method for modeling sequential problems; model uncertainty; state uncertainty; and cooperative decision making involving multiple interacting agents. A series of applications shows how the theoretical concepts can be applied to systems for attribute-based person search, speech applications, collision avoidance, and unmanned aircraft persistent surveillance. Decision Making Under Uncertainty unifies research from different communities using consistent notation, and is accessible to students and researchers across engineering disciplines who have some prior exposure to probability theory and calculus. It can be used as a text for advanced undergraduate and graduate students in fields including computer science, aerospace and electrical engineering, and management science. It will also be a valuable professional reference for researchers in a variety of disciplines.
Download or read book Chile written by International Monetary Fund. Western Hemisphere Dept. and published by International Monetary Fund. This book was released on 2016-12-09 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2016 Article IV Consultation highlights that GDP growth in Chile has been weak, with activity slowing in October. However, conditions are in place for the economy to recover. After expanding by a moderate 1.7 percent in 2016, growth is forecast to increase to 2 percent in 2017. Faster growth in main regional partners and more stable copper prices are expected to lift exports and investment. The recovery is, however, projected to be gradual, held back by slow wage and job growth and still low business confidence. The financial sector appears healthy. Banks’ profitability is declining, but capital buffers are adequate and nonperforming loan rates are low.

Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.
Download or read book Completing the Forecast written by National Research Council and published by National Academies Press. This book was released on 2006-10-09 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty is a fundamental characteristic of weather, seasonal climate, and hydrological prediction, and no forecast is complete without a description of its uncertainty. Effective communication of uncertainty helps people better understand the likelihood of a particular event and improves their ability to make decisions based on the forecast. Nonetheless, for decades, users of these forecasts have been conditioned to receive incomplete information about uncertainty. They have become used to single-valued (deterministic) forecasts (e.g., "the high temperature will be 70 degrees Farenheit 9 days from now") and applied their own experience in determining how much confidence to place in the forecast. Most forecast products from the public and private sectors, including those from the National Oceanographic and Atmospheric Administration's National Weather Service, continue this deterministic legacy. Fortunately, the National Weather Service and others in the prediction community have recognized the need to view uncertainty as a fundamental part of forecasts. By partnering with other segments of the community to understand user needs, generate relevant and rich informational products, and utilize effective communication vehicles, the National Weather Service can take a leading role in the transition to widespread, effective incorporation of uncertainty information into predictions. "Completing the Forecast" makes recommendations to the National Weather Service and the broader prediction community on how to make this transition.
