Assembly Line Balancing under Uncertain Task Time and Demand Volatility


Book Description

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.

Energy Efficiency in Manufacturing Systems


Book Description

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.




EBOOK: Operations and Supply Chain Management, Global edition


Book Description

Resourceful companies today must successfully manage the entire supply flow, from the sources of the firm, through the value-added processes of the firm, and on to the customers of the firm. The fourteenth Global Edition of Operations and Supply Chain Management provides well-balanced coverage of managing people and applying sophisticated technology to operations and supply chain management.




Rwanda


Book Description

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.
