Energy And Carbon Footprint Reduction During Textile-Based Product Design And Manufacturing, S. H. Seyedmahmoudi, Karl R. Haapala, Kyoung-Yun Kim, Gül Kremer

Industrial and Manufacturing Systems Engineering Publications

Due to concerns over non-renewable energy consumption and associated emissions, industry has sought methods and technologies to support energy efficiency practices and use of alternative energy during product manufacturing, use, and end-of-life. Efforts have been undertaken to more precisely calculate environmental metrics, such as energy consumption and carbon footprint, to support broader sustainable design activities. The work reported endeavours to integrate sustainability principles into the design of products, manufacturing processes, and relevant supply chain networks to assist decision makers. Two backpacks are evaluated to examine the influence of design choices on energy consumption and carbon footprint. The study system boundary ...


A Tri-Level Optimization Model For Inventory Control With Uncertain Demand And Lead Time, Mohammad Rahdar, Lizhi Wang, Guiping Hu Jan 2018

A Tri-Level Optimization Model For Inventory Control With Uncertain Demand And Lead Time, Mohammad Rahdar, Lizhi Wang, Guiping Hu

Industrial and Manufacturing Systems Engineering Publications

We propose an inventory control model for an uncapacitated warehouse in a manufacturing facility under demand and lead time uncertainty. The objective is to make ordering decisions to minimize the total system cost. We introduce a two-stage tri-level optimization model with a rolling horizon to address the uncertain demand and lead time regardless of their underlying distributions. In addition, an exact algorithm is designed to solve the model. We compare this model in a case study with three decision-making strategies: optimistic, moderate, and pessimistic. Our computational results suggest that the performances of these models are either consistently inferior or highly ...


A Framework For Collaboration Among Regional Food System Participants, Anuj Mittal, Veronica M. White, Caroline Krejci Jan 2017

A Framework For Collaboration Among Regional Food System Participants, Anuj Mittal, Veronica M. White, Caroline Krejci

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Horizontal collaboration can benefit supply chain partners by increasing their collective competitiveness. However, each participant in the collaboration typically maintains its own individual business objectives. Therefore, such collaborations require a standard operational framework that specifies the allocation of participant responsibilities and benefits. While horizontal collaboration in regional food supply chains is common, very few participants have adopted this type of standard framework. As a result, the sharing of resources and information among partners tends to be inefficient and potentially contentious. This paper describes our efforts to formalize a supply chain collaboration that has developed among several regional food hubs and ...

Engineering Management & Systems Engineering Faculty Publications

The importance and complexity of the problems associated with coordinating multiple organizations to configure value propositions for customers has drawn the attention of multiple disciplines. In an effort to clarify and consolidate terms, this conceptual research examines both supply chain management (SCM) and system of systems (SoS) literature to postulate, from a value-chain perspective, what roles integration and collaboration play in helping supply chains satisfy customer requirements. A literature review analysis was used to identify the commonalities and differences between supply chain management and system of systems approaches to examining interfirm coordination of value creation efforts. Although a framework of ...


Methodology For Simulation And Analysis Of Complex Adaptive Supply Network Structure And Dynamics Using Information Theory, Joshua V. Rodewald, John M. Colombi, Kyle F. Oyama, Alan W. Johnson Oct 2016

Methodology For Simulation And Analysis Of Complex Adaptive Supply Network Structure And Dynamics Using Information Theory, Joshua V. Rodewald, John M. Colombi, Kyle F. Oyama, Alan W. Johnson

Faculty Publications

Supply networks existing today in many industries can behave as complex adaptive systems making them more difficult to analyze and assess. Being able to fully understand both the complex static and dynamic structures of a complex adaptive supply network (CASN) are key to being able to make more informed management decisions and prioritize resources and production throughout the network. Previous efforts to model and analyze CASN have been impeded by the complex, dynamic nature of the systems. However, drawing from other complex adaptive systems sciences, information theory provides a model-free methodology removing many of those barriers, especially concerning complex network ...


Improving Carbon Efficiency Through Container Size Optimization And Shipment Consolidation, Nang Laik Ma, Kar Way Tan, Edwin Lik Ming Chong Sep 2016

Improving Carbon Efficiency Through Container Size Optimization And Shipment Consolidation, Nang Laik Ma, Kar Way Tan, Edwin Lik Ming Chong

Research Collection School Of Information Systems

Purpose: Many manufacturing companies that ship goods through full container loads found themselves under-utilizing the containers and resulting in higher carbon footprint per volume shipment. One of the reasons is the choice of non-ideal container sizes for their shipments. Consolidation fills up the containers more efficiently that reduces the overall carbon footprint. The objective of this paper is to support decisions on selection of appropriate combination of container sizes and shipment consolidation for a manufacturing company. We develop two-steps model which first takes the volumes to be shipped as an input and provide the combination of container sizes required; then ...


An Integrated Strategy For A Production Planning And Warehouse Layout Problem: Modeling And Solution Approaches, Guoqing Zhang, Tatsushi Nishi, Sarina D. O. Turner, Keisuke Oga, Xindan Li Jun 2016

An Integrated Strategy For A Production Planning And Warehouse Layout Problem: Modeling And Solution Approaches, Guoqing Zhang, Tatsushi Nishi, Sarina D. O. Turner, Keisuke Oga, Xindan Li

Mechanical, Automotive & Materials Engineering Publications

We study a real-world production warehousing case, where the company always faces the challenge to find available space for their products and to manage the items in the warehouse. To resolve the problem, an integrated strategy that combines warehouse layout with the capacitated lot-sizing problem is presented, which have been traditionally treated separately in the existing literature. We develop a mixed integer linear programming model to formulate the integrated optimization problem with the objective of minimizing the total cost of production and warehouse operations. The problem with real data is a large-scale instance that is beyond the capability of optimization ...


Evaluation Of The Impacts Of Governmental Policies On The Biofuels Supply Chain Design Under Uncertainty, Narges Kazemzadeh, Guiping Hu Jan 2015

Evaluation Of The Impacts Of Governmental Policies On The Biofuels Supply Chain Design Under Uncertainty, Narges Kazemzadeh, Guiping Hu

Industrial and Manufacturing Systems Engineering Publications

There is a growing interest in the use of biomass as a source of energy around the world. In the United States, the Renewable Fuel Standard (RFS) sets policies and mandates to support the production and consumption of biofuels. However, the uncertainties associated with the governmental and local policies and regulations on both production and consumption have imposed significant impacts on the biofuel supply chain network. This study aims to determine the optimal design of the biofuel supply chain to maximize annual profit under the impacts of governmental policies. In this study, two-stage stochastic programming models are developed in which ...


Multi-Agent Simulation Modeling Of Supplier Selection For Local Food Systems, Hardik D. Bora, Caroline C. Krejci Jan 2015

Multi-Agent Simulation Modeling Of Supplier Selection For Local Food Systems, Hardik D. Bora, Caroline C. Krejci

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Consumer demand for regionally-produced food has increased dramatically in the past decade, in response to concerns over food safety and quality, as well as the serious environmental, economic, and social equity issues that pervade the modern industrial food supply system. As demand grows, distributors of regionally-produced food (i.e., food hubs) face many challenges in their efforts to scale up, particularly with supply chain management. They must find ways to operate more efficiently without undermining their support for the regional farming community. In this paper we describe a multi-agent simulation model of a theoretical regional food system in which multiple ...


The People Dimension In Logistics And Supply Chain Management – Its Role And Importance, Edward Sweeney May 2013

The People Dimension In Logistics And Supply Chain Management – Its Role And Importance, Edward Sweeney

Books/Book chapters

It is widely recognised that the effective application of logistics and supply chain management (SCM) has a vital role to play in European economic recovery. Experience suggests that success in achieving higher levels of supply chain integration (SCI) depends on both physical and technical components (the hard-wiring), as well as human and behavioural components (the soft-wiring). There is significant evidence that the latter has been largely neglected by the logistics and SCM community. Furthermore, it appears that the majority of supply chain improvement initiatives by practitioners have been primarily concerned with technological, structural and process issues. This chapter argues that ...


Has Supply Chain Management Lost Its Relevance?, Natalie Descheres Jan 2013

Has Supply Chain Management Lost Its Relevance?, Natalie Descheres

Books/Book chapters

The context of business has changed dramatically over the last 15 years. The definition of need satisfaction, the shift from “dot to web” competition and the embedding of the organisation into a wider political and societal environment has transformed SCM contributions and the meaning of work for employees. Interdependence must evolve from the do-it-alone approach and yet the ashes are not proving fertile ground. In many ways, traditional models of management have not kept up with the changes and are taken aback by the complexity that surrounds us. Complexity is however not a feature of our world, but one of ...


Where Next For Supply Chain Management?, Des Lee Jan 2013

Where Next For Supply Chain Management?, Des Lee

Books/Book chapters

Supply chain management (SCM) has been so successful that it is largely taken for granted. Its success has been built on improving three key flows – of product, of money and of information – and on one core principle – core competence. What next for SCM? This article outlines the vulnerabilities that are embedded in modern supply chains and the unintended consequences of outsourcing activities that are not core competences. These consequences are global and have the potential to undermine past achievements. Finally, broad suggestions are made as to how these issues can be addressed and the areas on which supply chain management ...

This paper examines the underlying logic behind the rules configured in a RFID middleware to support “smart business processes” in one retail supply chain. Through a detailed investigation of the underlying business processes, we will demonstrate how businesses rules can be defined, configured and refined in a RFID middleware. The results confirm that RFID technology is not a “Plug and Play” solution. RFID middleware configuration will require a high level of customization. Finally, this study allows the improvement of our understanding of the real potential of RFID technology in the supply chain context.
