Sustainable Business Models


Book Description

This book provides a comprehensive exploration into the identification and development of sustainable business models as well as their implementation, management and evaluation. With ever-increasing pressure on organisations to respond to societal change and improve competition through sustainable business model innovation (SBMI), this book aims to contribute to the knowledge of their design and management. The chapters explore the role of partnerships, the Internet of Things and the circular economy, among other factors, in developing SBM and how SBMI is facilitated through ideation and in entrepreneurial settings. Providing new typologies, patterns and a framework to evaluate the level of sustainability of business models, this book critically reviews existing literature on the topic to examine the potential of SBMI in research and in practice. The contributing authors employ a number of case studies and case examples to illustrate the integration of sustainable business models throughout the value chain, and their influence on wider social, environmental and business activities.




Spacecraft Formation Flying


Book Description

Space agencies are now realizing that much of what has previously been achieved using hugely complex and costly single platform projects—large unmanned and manned satellites (including the present International Space Station)—can be replaced by a number of smaller satellites networked together. The key challenge of this approach, namely ensuring the proper formation flying of multiple craft, is the topic of this second volume in Elsevier's Astrodynamics Series, Spacecraft Formation Flying: Dynamics, control and navigation. In this unique text, authors Alfriend et al. provide a coherent discussion of spacecraft relative motion, both in the unperturbed and perturbed settings, explain the main control approaches for regulating relative satellite dynamics, using both impulsive and continuous maneuvers, and present the main constituents required for relative navigation. The early chapters provide a foundation upon which later discussions are built, making this a complete, standalone offering. Intended for graduate students, professors and academic researchers in the fields of aerospace and mechanical engineering, mathematics, astronomy and astrophysics, Spacecraft Formation Flying is a technical yet accessible, forward-thinking guide to this critical area of astrodynamics. - The first book dedicated to spacecraft formation flying, written by leading researchers and professors in the field - Develops the theory from an astrodynamical viewpoint, emphasizing modeling, control and navigation of formation flying satellites on Earth orbits - Examples used to illustrate the main developments, with a sample simulation of a formation flying mission included to illustrate high fidelity modeling, control and relative navigation
