Available in PDF, EPUB and Kindle. Book excerpt: Flexible system design has received increasingly more attention in the last a few decades. Flexibility can increase systems' ability to adjust against fast-changing environment, and thereby improves efficiency and reliability, and avoids huge cost from rare but severe disruptions, or loss due to congestions caused by system uncertainties. In this dissertation, we focus on the design and management of flexible systems. In particular, we study three types of flexibility: process flexibility, network flexibility, and payment flexibility. We present quantitative formulations for these problems, and develop different methodologies to solve them. We further conduct numerical studies to generate insights as guidelines for the design of flexible systems in practice. \\ Flexible supply chains have been widely used by companies to deal with uncertainties. It is well known that chaining structure is very efficient in balanced supply chains. However, it is not clear whether it will work well when supply chains are unbalanced. We study the flexibility design problem of a general supply chain with unbalanced and nonhomogeneous structure. Both demand uncertainty and disruptions are considered in our model. We derive exact solutions for several special cases of the uncapacitated problem where the number of links is fixed, propose an efficient algorithm for solving the general uncapacitated problem, and use simulations to derive some managerial insights for the capacitated problem.\\ A similar idea is applied to network design. Air transportation networks suffer a lot from disruptions caused by severe weather, natural disasters, power outage, etc. We propose a flexible hub-and-spoke structure in which airports are allowed to have up to $N$ hubs, and formulate the problem as a mixed-integer program that minimizes fixed cost, flexibility cost, and expected transportation cost and penalty cost. Benders decomposition algorithm is applied to solve this problem. Numerical studies show that the performance of the network can be improved substantially with flexible hub assignment, and a flexible structure with $N=2$ can achieve most of the benefit of those with greater $N$. We also demonstrate the impact of the correlation between airport disruptions and address the importance of considering it in stochastic air transportation models.\\ Trade credit, as a form of flexible payment, is a major tool used by small businesses to obtain external finance. It benefits the buyer and the supplier in multiple ways, and brings risk to them at the same time. We investigate the impact of trade credit on growing small businesses and their suppliers. By looking at a one-supplier-one-retailer supply chain, we study the expansion and inventory policies of the retailer when trade credit is extended or not. It is shown that the retailer grows faster and orders more with trade credit. It is also shown by numerical study that the effect of trade credit depends on demand correlation. When demand is positively correlated, trade credit makes the retailer more likely to go bankrupt, and thereby lowers the supplier's long-term profit and may even cause the failure of the supplier.

Available in PDF, EPUB and Kindle. Book excerpt: An introduction to a powerful and flexible network modeling tool for developing and understanding complex systems, with many examples from a range of industries. Design structure matrix (DSM) is a straightforward and flexible modeling technique that can be used for designing, developing, and managing complex systems. DSM offers network modeling tools that represent the elements of a system and their interactions, thereby highlighting the system's architecture (or designed structure). Its advantages include compact format, visual nature, intuitive representation, powerful analytical capacity, and flexibility. Used primarily so far in the area of engineering management, DSM is increasingly being applied to complex issues in health care management, financial systems, public policy, natural sciences, and social systems. This book offers a clear and concise explanation of DSM methods for practitioners and researchers.

Download or read book Community Biodiversity Management written by Walter Simon de Boef and published by Routledge. This book was released on 2013-03-12 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation and sustainable use of biodiversity are issues that have been high on the policy agenda since the first Earth Summit in Rio in 1992. As part of efforts to implement in situ conservation, a methodology referred to as community biodiversity management (CBM) has been developed by those engaged in this arena. CBM contributes to the empowerment of farming communities to manage their biological resources and make informed decisions on the conservation and use of agrobiodiversity. This book is the first to set out a clear overview of CBM as a methodology for meeting socio-environmental changes. CBM is shown to be a key strategy that promotes community resilience, and contributes to the conservation of plant genetic resources. The authors present the underlying concepts and theories of CBM as well as its methodology and practices, and introduce case studies primarily from Brazil, Ethiopia, France, India, and Nepal. Contributors include farmers, leaders of farmers’ organizations, professionals from conservation and development organizations, students and scientists. The book offers inspiration to all those involved in the conservation and use of agrobiodiversity within livelihood development and presents ideas for the implementation of farmers’ rights. The wide collection of experiences illustrates the efforts made by communities throughout the world to cope with change while using diversity and engaging in learning processes. It links these grassroots efforts with debates in policy arenas as a means to respond to the unpredictable changes, such as climate change, that communities face in sustaining their livelihoods.

Book excerpt: Synthesizes the empirical literature on organizationalstructuring to answer the question of how organizations structure themselves --how they resolve needed coordination and division of labor. Organizationalstructuring is defined as the sum total of the ways in which an organizationdivides and coordinates its labor into distinct tasks. Further analysis of theresearch literature is neededin order to builda conceptualframework that will fill in the significant gap left by not connecting adescription of structure to its context: how an organization actuallyfunctions. The results of the synthesis are five basic configurations (the SimpleStructure, the Machine Bureaucracy, the Professional Bureaucracy, theDivisionalized Form, and the Adhocracy) that serve as the fundamental elementsof structure in an organization. Five basic parts of the contemporaryorganization (the operating core, the strategic apex, the middle line, thetechnostructure, and the support staff), and five theories of how it functions(i.e., as a system characterized by formal authority, regulated flows, informalcommunication, work constellations, and ad hoc decision processes) aretheorized. Organizations function in complex and varying ways, due to differing flows -including flows of authority, work material, information, and decisionprocesses. These flows depend on the age, size, and environment of theorganization; additionally, technology plays a key role because of itsimportance in structuring the operating core. Finally, design parameters aredescribed - based on the above five basic parts and five theories - that areused as a means of coordination and division of labor in designingorganizational structures, in order to establish stable patterns of behavior.(CJC).
