Factors Impacting Technology Transfer: The Maquiladora Industry In Yucatan, Mexico, Ana Maria Canto, Carlos Blanco, Pilar Pazos

Engineering Management & Systems Engineering Faculty Publications

Technology transfer and knowledge transfer are the building blocks for innovation, efficiency and increased competitiveness. The topic of technology transfer in the context of multinational companies has been the focus of technology management researchers for well over two decades. Developing countries housing twin plans have been exposed to technology transfer from very diverse countries with different approaches to the technology transfer process and different levels of success. This cultural and national diversity adds an additional level of complexity to the technology transfer domain that has been largely unexplored. This paper will explore critical factors that had an impact in successful …

Decision Support Models For The External Variety Of Configurable Products, Erkan Isikli

Wayne State University Dissertations

The decision of what configurations of a product to offer is a difficult one for marketing and sales departments. In this study, we developed decision support models that can help decision makers when using operational models to manage external variety of configurable products. Our main objective is to reduce the number of product variants offered in a proper way so that inventory and demand models do not suffer from the curse of dimension. Due to its ability and flexibility, our framework can be employed under various marketing actions. We applied our framework to both qualitative and quantitative data.

Impact Of Rotated Aisles On Travel Distance In Manufacturing Facilities, Dale Masel, Samantha Hedges

12th IMHRC Proceedings (Gardanne, France – 2012)

To design a facility, expected flows between the resources is one of the most important input. Flows are usually calculated given some statistics of previous periods or from the expected demand and the process required. However, in a refurbishing and recycling facility, flows are very fluctuating and not trivial to predict. The quantity produced by such facility not only depends on the demand but also on the supplies which are returned products under guaranty or discarded products after their end-of-use. The uncertainty and the variability on these supplies are often higher than the one on the demand which makes it …

Simulation-Based Performance Improvement Of A Defense Logistics Warehouse, Banu Y. Ekren, Gerald W. Evans, Sunderesh S. Heragu, John S. Usher

12th IMHRC Proceedings (Gardanne, France – 2012)

Warehouses play a critical role in supply chains. They serve as a vital link between manufacturers and customers. In this study, we investigate performance of the largest warehouse (Eastern Distribution Center - EDC) of the Defense Logistics Agency (DLA) located in New Cumberland, PA and propose a near optimum design for the receiving area of the warehouse to improve its performance. First, we develop a simulation model of the system. Second, we interface an optimization model with the simulation in order to optimize the number of people working at the induction stations. In the optimization model, our goal is to …

Optimal Design Of Container Terminal Layout, Debjit Roy, Ren´E De Koster

12th IMHRC Proceedings (Gardanne, France – 2012)

Due to rapid growth in foreign trade using sea vessels, there is a growing focus in improving the infrastructure and operational efficiencies at the container terminals. Particularly, the operational responsiveness of loading and unloading of containers, affects the vessel idle times and profitability of the shipping liners. In this research, we deter- mine optimal stack layout design, which minimizes the container unload times using Automated Guided Vehicles (AGVs). To analyze alternate stack layout designs, we develop integrated queuing network models that capture the stochastic interactions among the container terminal processes (quayside, vehicle transport, and stack side), and provides realistic estimates …

Cycle Time Models For Aisle Changing As/Rs Considering Acceleration/Deceleration, Jörg Oser

12th IMHRC Proceedings (Gardanne, France – 2012)

In multi-aisle AS/RS systems one or more S/R machines serve several aisles with storage racks on both sides of the aisle. An important feature of multi-aisle configurations are aisle changing devices with transfer cars, curve guided aisle switching mechanisms or closed loop rail tracks with curved sections for a two-aisle layout. These systems offer an economic solution, when the number of storage and retrieval transactions is low and storage volume is high. One or several S/R machines each serving a specified number of aisles can be arranged in various layouts to meet the required storage capacity and throughput.

The Order Picking Problem In Fishbone Aisle Warehouses, Melih Celik, Haldun Sural

12th IMHRC Proceedings (Gardanne, France – 2012)

A recent trend in the layout design of unit load warehouses is the application of layouts without conventional parallel pick aisles and straight middle aisles. Two examples for such designs are flying- V and fish bone designs for single and dual command operations. In this study, we consider the same layout types under the case of multiple-item pick lists and show that, for both layout types, the routing problem can be solved in polynomial time. We also propose simple heuristics for this problem inspired by those put forward for parallel-aisle warehouses. Our computational results reveal that under certain cases, fish …

How To Choose An Order-Picking System, Marita Ellinger, Tim Geißen, Detlef Spee

12th IMHRC Proceedings (Gardanne, France – 2012)

Order-Picking-Systems are the parts of material flow systems, which have the largest variance of deployment alternatives. Since a long time there have been many attempts to systematize the way of identification of the order-picking- ystem that the “correct” solution can be found. The previous methods could not be enforced universally. Thus nearly all the material handling system suppliers have their own approach to find the right system, as it turned out at a market analysis of Fraunhofer IML. With the presented concept of finding a solution, a structured, fast method for system identification shall be presented. A stepwise approach to …

Evaluation Of Environmental Benefits Of Che Emerging Technologies By Using Lca, Nenad Zrnić, Andrija Vujičić

12th IMHRC Proceedings (Gardanne, France – 2012)

In the era of climate change combat transport industry is recognized as a sector with one of the largest environmental footprints. A part of transport industry is container shipping and handling division, which is currently growing with the fastest rate. This massive growth of container sector is due to containers pouring from Asia, mainly from China. Thus, container port operations are also experiencing significant increase in port emissions. This fact puts port authorities in position to find a way to reduce environmental impact of port operations and at the same time withhold increase in number containers being handled. In response …

Robust Design Of Public Storage Warehouses, Yeming Yale Gong, Rene De Koster

12th IMHRC Proceedings (Gardanne, France – 2012)

We apply robust optimization and revenue management in public storage warehouses. We optimize the expected revenue of public storage warehouses against the worst cases with a max-min revenue objective, and the decision variables are mainly the number of storage units for each storage type. With the robust design, we can observe worst-case revenue improvement.

Humanitarian Logistics – The First Week, Selina Begum, Bill Ferrell

12th IMHRC Proceedings (Gardanne, France – 2012)

Decisions made on material flow during the first week of a natural disaster are critical for victims. Currently, decision makers appears to be making important choices based on experience and intuition with little or no support from quantitative approaches because they do not exist. This research proposes a paradigm and offers two supporting models that will assist decision makers regarding the routing of materials during the first week of a disaster. It explicitly includes information regarding the victims’ needs and the degree to which routes are available in a quantitative way that allows updating as information improves. The paradigm involves …

A High-Density, Puzzle-Based Order Picking System, Kevin R. Gue, Onur Uludag

12th IMHRC Proceedings (Gardanne, France – 2012)

We present a new semi-automated system for carton and piece picking operations in the distribution centers. The system features decentralized control based on a message-passing protocol in which cells communicate with their neighbors to determine action in each step. The result is a dynamically changing pick face that provides high sku density and reduced worker travel. We describe an example in which pickers are 20% to 50% more productive than they would be in an equivalent ow rack system.

Using Buffers And Work-Sharing For Minimizing Makespan Of Small Batches In Assembly Lines Under Learning Effects, Yossi Bukchin, Efrat Wexler

12th IMHRC Proceedings (Gardanne, France – 2012)

The effect of workers’ learning curve on production rate in manual assembly lines is significant when producing relatively small batches of different products. This research analyzes this effect and suggests applying work-sharing among the workers in such an environment to improve the time to complete the batch, namely, the makespan. Work-sharing refers to a situation where adjacent workers help each other in order to reduce idle times caused by blockage and starvation. The effect of work-sharing and existence of buffers on the makespan is examined and compared to a baseline situation, with no work-sharing and buffers. We present mixedinteger linear-programing …

12th IMHRC Proceedings (Gardanne, France – 2012)

Environmental issues have been the focus of much discussion and debate. In light of environmental concerns, many companies have focused on creating sustainable products and systems. While there is still much disagreement about what is “sustainable,” there is a lot of on-going activity cover a wide range of areas and topics. However, relatively speaking, there is much less attention and activity within a facility logistics context. In this paper, sustainability issues related to facility logistics are explored. An overview of existing related research across a range of areas is provided. Major issues of concern for facility logistics will be discussed …

Column Generation For The Container Relocation Problem, Elisabeth Zehendner, Dominique Feillet

12th IMHRC Proceedings (Gardanne, France – 2012)

Container terminals offer transfer facilities to move containers from vessels to trucks, trains and barges and vice versa. Within the terminal the container yard serves as a temporary buffer where incoming containers are piled up in stacks. Only the topmost container of each stack can be accessed. If another container has to be retrieved, containers stored above it must be relocated first. Containers need to be transported to a ship or to trucks in a predefined sequence as fast as possible. Generally, this sequence does not match the stacking order within the yard. Therefore, a sequence of retrieval and relocation …

Functional Design Of Physical Internet Facilities: A Road-Based Transit Center, Russell D. Meller, Benoit Montreuil, Collin Thivierge, Zachary Montreuil

An Object Oriented And Axiomatic Theory Of Warehouse Design, Leon F. Mcginnis

12th IMHRC Proceedings (Gardanne, France – 2012)

Despite the conceptual simplicity of warehousing, the development of integrated computational tools for warehouse design has remained an elusive goal. In recent years, there has been some progress toward this goal, with a growing body of research addressing topics as diverse as the design process itself, decision support for specific design decisions, warehouse representation, integrating warehouse representation and analysis, and conceptual approaches for developing integrated warehouse design tool chains. Until now, however, there has not been a suitable warehouse design theory that would provide an integrating framework for all these disparate efforts. This paper presents an object-oriented and axiomatic warehouse …

A Comparison Of Priority Rules For Non-Passing Automated Stacking Cranes, Hector J. Carlo, Azaria Del Valle-Serrano, Fernando L. Martinez-Acevado, Yaritza M. Santiago-Correa, Iris F.A. Vis

12th IMHRC Proceedings (Gardanne, France – 2012)

A recent trend in container ports is to operate dual non-passing Automated Storage Cranes (ASCs) that collaborate to serve storage and retrieval requests from opposite ends of a storage block. Since the ASCs are unable to pass each other, there is an exchange zone that serves as a temporary storage location so that one crane can start a request and leave it to the other crane to complete it. In this study, twelve priority rules are introduced and evaluated to determine which rule minimizes the total makespan for serving all requests, given the sequence in which each ASC will serve …

Analysis Of Material Handling Systems Based On Discrete Time Design Modules, Furmans Kai, Ozden Eda, Stoll Judith, Epp Martin, Schmidt Thorsten, Meinhardt Ingolf, Schulze Frank

12th IMHRC Proceedings (Gardanne, France – 2012)

In this paper, we present a method for the performance evaluation of material handling systems in an early planning stage. We are mapping typical material handling elements onto stochastic analytical models. Our intention is to build a toolbox of material handling modules that allows a fast analysis of typical continuous conveying systems. The tool should enable the identification of bottlenecks and the computation of lead time distributions for intra-logistic systems.
