robust Global Supply Chain network design under disruption and uncertainty considering resilience strategies a parallel memetic algorithm for a real life case study
Transportation Research Part E-logistics and Transportation Review, 2016Co-Authors: Aliakbar Hasani, Amirhossein KhosrojerdiAbstract:A mixed-integer, non-linear model is developed for designing robust Global Supply Chain networks under uncertainty. Six resilience strategies are proposed to mitigate the risk of correlated disruptions. In addition, an efficient parallel Taguchi-based memetic algorithm is developed that incorporates a customized hybrid parallel adaptive large neighborhood search. Fitness landscape analysis is used to determine an effective selection of neighborhood structures, while the upper bound found by Lagrangian relaxation heuristic is used to evaluate quality of solutions and effectiveness of the proposed metaheuristic. The model is solved for a real-life case of a Global medical device manufacturer to extract managerial insights.

robust closed loop Global Supply Chain network design under uncertainty the case of the medical device industry
International Journal of Production Research, 2015Co-Authors: Aliakbar Hasani, Seyed Hessameddin Zegordi, Ehsan NikbakhshAbstract:Improving performance of Global Supply Chains requires careful consideration of various factors including distance from markets, access to resources, exchange and tax rates, import tariffs, and trade regulations. In this paper, a comprehensive optimization model is proposed to maximise the after-tax profit of a closed-loop Global Supply Chain for medical devices under uncertainty. The uncertainty of the decision-making environment is modelled using the budget of uncertainty concept in interval robust optimization. International financial issues due to the Economic Cooperation Organisation Trade Agreement as well as national regulations including transfer pricing limitations, exchange rates, tax rates, and import tariffs are considered. The proposed model considers various realistic assumptions pertaining to medical device Supply Chains such as multiple products, multiple periods, multiple echelons, and limited warehousing lifetime. In addition, reverse flows of perished and defective products are consider...

an overview of arable land use for the world economy from source to sink via the Global Supply Chain
Land Use Policy, 2018Co-Authors: Xudong D Wu, G Q ChenAbstract:Abstract As an extension of a previous work ( Chen and Han, 2015a ), this study explored the arable land use of the world economy from source of exploitation to sink of final consumption via the Global Supply Chain, by means of embodiment accounting that includes the indirect feedbacks associated with both intermediate and primary inputs. In magnitude, the Global transfer of arable land use is estimated to be around 40% of the total direct exploitation. The connections as well as imbalances of major economies in intermediate and final trades of arable land use are discussed. Canada, Australia, Argentina, Pakistan and African regions turn out to have a massive deficit of arable land use in both intermediate and final trades. In contrast, the United States, Japan, Mainland China, the United Kingdom, Germany and France obtain a surplus of arable land use in both intermediate and final trades by land displacement in those net exporters. Indices in terms of arable land use self-sufficiency rate by source and that by sink are devised. For India as the biggest source region, around 20% of the arable land resources exploited locally are for final consumption abroad. For the United States as the largest sink region, around 40% of its arable land use originates from foreign regions led by Canada. For Japan as the biggest net importer in both intermediate and final trades, over 90% of its arable land use comes from foreign economies led by African and Asian regions. For sustained development, regions are suggested to be more adapted to the Global Supply Chain based on their behaviors in both intermediate and final trades of arable land use.

Global Supply Chain of arable land use production based and consumption based trade imbalance
Land Use Policy, 2015Co-Authors: G Q ChenAbstract:Closely related to food Supply, arable land use has been extensively studied, especially regarding booming Global trade activities. However, the analysis on trade patterns of arable land use, particularly in terms of intermediate use and final demand, is still lacking. To shed light on the complex arable land use relationships among economies, the Global Supply Chain of arable land use is intensively explored in the present work by a systems multi-regional input-output analysis for the year of 2010, with focus on the trade patterns from the perspective of production and consumption. Global arable land use embodied in international trade is estimated near one third the Global arable land use, and that embodied in intermediate use is almost twice that embodied in final demand. Arable land use trade patterns are noted in terms of production-based imports/exports and consumption-based imports/exports. Most notably, Mainland China is shown as the leading production-dominated importer. With regard to other large economies, Canada is found as a production-oriented exporter, in contrast to Australia as a consumption-oriented exporter. Japan is identified as a production-oriented importer, while the United States is a consumption-oriented importer. As heavy trade imbalance is revealed prevailing not only between countries and regions but also between intermediate products and final goods, the study to explore Global Supply Chains of arable land use can provide essential policy making implications for security and sustainability in arable land use and food Supply on both Global and regional scales.

connecting product design process and Supply Chain decisions to strengthen Global Supply Chain capabilities
International Journal of Production Economics, 2014Co-Authors: Erika Marsillac, James Jungbae RohAbstract:Abstract The importance of product design as a main determinant of process design has been emphasized in operations management literature for decades, but the direct and indirect impacts of product design on process and Supply Chain activities is a research area that has received less attention to date. This multiple case study addresses this research gap by assessing how and why changes in product design shape process and Supply Chain practices and in particular, how these changes influence Global Supply Chain behavior and capabilities. Utilizing a 3DCE theory base, multiple manufacturing case studies are compared and contrasted to examine the interrelationships and dependencies among product, process and Supply Chain behaviors and capabilities. Product design changes were found to alter the scope and scale of process and Supply Chain modifications in specific ways that alter firms' competitive product design customization capabilities and competencies; flexible, advanced process technologies; and collaborative supplier practices. This study contributes to operations management literature by providing a rich empirical analysis of operations system interplay. The study develops substantive research propositions and a 3DCE theoretical framework that may be used to drive future operations management research and in addition, provides managerial insights that can be used to strengthen Supply Chain capabilities in a Global and dynamic context.

A stochastic model for risk management in Global Supply Chain networks
European Journal of Operational Research, 2007Co-Authors: Mark Goh, Joseph Lim, Fanwen MengAbstract:Abstract With the increasing emphasis on Supply Chain vulnerabilities, effective mathematical tools for analyzing and understanding appropriate Supply Chain risk management are now attracting much attention. This paper presents a stochastic model of the multi-stage Global Supply Chain network problem, incorporating a set of related risks, namely, Supply, demand, exchange, and disruption. We provide a new solution methodology using the Moreau–Yosida regularization, and design an algorithm for treating the multi-stage Global Supply Chain network problem with profit maximization and risk minimization objectives.
