Data Mining Based Threshold Development For Novelty Detection, Poovich Phaladiganon

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

The objective of this dissertation is to develop thresholds for novelty detection with applications to statistical process control (SPC). SPC is a widely used technique for improving process and product quality. The primary tool of SPC is a control chart that is used to monitor and detect abnormal processes. Traditional control chart techniques usually require a specific distributional assumption, typically the normal distribution, to establish their control limits. However, in modern manufacturing processes, the normality assumption is often violated. Novelty detection more generally seeks abnormal (or novel) patterns in data, and novelty detection techniques can be applied to control charts …

The Pricing Of Multiple Exercisable American-Style Real Options, Yu Meng

Doctoral Dissertations

"Real options embedded in a project provide management with the flexibility to alter initial investment decisions, thus making them a practical tool for project planning and budgeting. Additional values are contributed to the underlying project due to the flexibilities that are provided by real options. This dissertation presents two models for pricing multiple exercisable American real options, one that employs the binomial tree method and the other one that employs the finite difference method. Different examples of multiple exercisable real options are discussed to demonstrate the two pricing models. Interactions between options and reality constraints are also considered. These two …

Two Essays On The Domain Translation From Financial Options To Real Options, Hongyan Chen

Doctoral Dissertations

"Real options (ROs) extend the financial option pricing theory to the valuation of real asset investment and managerial flexibility under uncertainty. However, differences between financial and non-financial markets, and the complex real world environment of applications, build obstacles for the domain translation from financial options to ROs.

This dissertation is motivated by the challenges of domain translation and developed in two essays. The first essay studies the incentive function of ROs (named the RO incentive). The essay develops an option-game framework to model the RO incentive, examines the change of investment behavior caused by the RO incentive, and values the …

Enabling Systems And The Adaptability Of Complex Systems-Of-Systems, Charles O. Adler, Cihan H. Dagli

Engineering Management and Systems Engineering Faculty Research & Creative Works

For complex techno-social system-of-systems, the system's robustness and its ability to adapt to changing environments and circumstances over the life cycle of the systems is an important measure of system quality and effectiveness. the IEEE 15288-2004 standard describes the concept of "enabling systems" that provide non-operational services to the system-of-interest at various times in the system life cycle. This concept of enabling systems provides critical components and perspective in the architecting and analysis of systems-of-systems adaptability and capabilities over time. Enabling systems also provide a potential strong link between the technical system and larger environmental effects such as economic conditions. …

Fuzzy Assessor Using Type 1 And Type 2 Fuzzy Sets, Paulette Acheson, Cihan H. Dagli

Engineering Management and Systems Engineering Faculty Research & Creative Works

This paper provides a fuzzy assessor that can be used to evaluate system architectures. the fuzzy assessor includes a method of assigning system architecture attribute values to the lower-level subsystems using type 1 fuzzy sets and type 2 fuzzy sets. Each architecture attribute is evaluated at the lowest subsystem level and then mathematically rolled-up to provide the system level value for each architecture attribute. Then the value for each architecture attribute is combined into an overall system architecture performance value. This provides a mathematical method of qualitatively assessing a system architecture based on key architecture attributes. the fuzzy assessor uses …

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 …

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 …

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 …
