Energy And Carbon Footprint Reduction During Textile-Based Product Design And Manufacturing, S. H. Seyedmahmoudi, Karl R. Haapala, Kyoung-Yun Kim, Gül Kremer Jun 2018

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 ...


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 ...


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 ...
