An Interval Based Approach To Model Input Uncertainty In Discrete-Event Simulation, Ola Batarseh

Electronic Theses and Dissertations

The objective of this research is to increase the robustness of discrete-event simulation (DES) when input uncertainties associated models and parameters are present. Input uncertainties in simulation have different sources, including lack of data, conflicting information and beliefs, lack of introspection, measurement errors, and lack of information about dependency. A reliable solution is obtained from a simulation mechanism that accounts for these uncertainty components in simulation. An interval-based simulation (IBS) mechanism based on imprecise probabilities is proposed, where the statistical distribution parameters in simulation are intervals instead of precise real numbers. This approach incorporates variability and uncertainty in systems. In …

Adaptive Pain Management Decision Support System, Ching-Feng Lin

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Pain management is an international health issue. The Eugene McDermott Center for Pain Management at the University of Texas Southwestern MedicalCenter at Dallas conducts a two-stage interdisciplinary pain management program that considers a wide variety of treatments. Prior to treatment (stage 1), an evaluation records the patient's pain characteristics, medical history and related health parameters. A treatment regime is then determined. At the midpoint of their program (stage 2), an evaluation is conducted to determine if an adjustment in the treatment should be made. A final evaluation is conducted at the end of the program to assess final outcomes. The …

Corporate Environmental Performance Rating Methodology, Arunapprakasini Sankaranarayanan

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Environmental issues are becoming increasingly important to all kinds of stakeholders and companies themselves, not only for cost avoidance due to regulations, laws, cleanup costs, litigations, controversies, etc, but to improve their intrinsic ethical worth as a company for better environmental sustainability. Off late, companies are increasingly investing in environmental initiatives for cost savings and to generate profits as well. However, since no clear definition of greenness exists, companies are finding it difficult to measure environmental performance as an internal and external benchmark and hence a sound performance measurement system with formal guidelines is yet to be in place. What …

Goal Approach To Risk Scenario Identification In Systems Development, Cesar Ariel Pinto, Andreas Tolk, Rafael Landaeta

Engineering Management & Systems Engineering Faculty Publications

The scope of this paper is the exploration of fundamental issues in identifying risk scenarios during systems development. Systems development refers to a series of processes which span conceptualization, designing the architecture, obtaining the elements, and eventually integrating all these elements into the fully developed final system. For truly sustainable and green systems, identifying risk scenarios early and continuously over the system development processes is vital. This paper contains various descriptions of risk from the project (i.e. programmatic) and technical perspectives, an exploration of the generally accepted risk management process, and how these relate to systems development through system goals. …

Towards A Center For Modeling And Simulation: The Case For Jordan, Ghaith Rabadi, Hazem Kaylani, Joseph Barjis (Ed.), Murali Mohan Narasipuram (Ed.), Ghaith Rabadi (Ed.), Jolita Ralyt (Ed.), Pierluigi Plebani (Ed.)

Engineering Management & Systems Engineering Faculty Publications

Modeling and Simulation (M&S) has recently become an important area that is pursued by many researchers and practitioners due to the role it plays in understanding complex systems and problems. We have therefore witnessed the establishment of many M&S organizations in the last two decades especially in the more developed world. Less developed countries are starting to recognize the need for such capability especially that the problems they face are not less complex. In this paper, we present a preliminary study towards a business plan for establishing a scientific center for Modeling, Analysis, Simulation and Animation in Jordan (JoSAMA) and …

Environmentally-Conscious Supply Chain Design In Support Of Food Security, Caroline C. Krejci, Benita M. Beamon

Industrial, Manufacturing, and Systems Engineering Faculty Publications - Archive

This paper seeks to design food supply chain structures that can provide food security for every person in the world while supporting long-term environmental sustainability. In particular, we provide alternatives to the current food supply chain structure and analyze their potential for providing food security, in terms of productive capacity and long-term environmental sustainability. Given the current world population and expected continued growth, our analysis suggests that environmentally-sustainable food supply chains would be most effectively supported by local and organic agriculture, while maintaining a parallel industrial agricultural system. This hybrid system would adopt environmentally-sustainable principles whenever possible, seeking to increase …

Measurement And Analysis Of Temperature And Pressure In High Altitude Air Shipments, Sher Paul Singh, Jay Singh, J. Stallings, Gary J. Burgess, K. Saha

Industrial Technology and Packaging

This study was performed (at the request of the FAA) to measure temperature and pressure conditions observed by standard packages in the FedEx Next Day Air network and the environmental conditions of passenger aircrafts. To measure the single parcel environment, two destinations known to be served by non-pressurized feeder and pressurized aircrafts in the USA, San Luis Obispo, California, and Twin Falls, Idaho, were used to represent higher altitude paths. Test packages (0.30 × 0.30 × 0.30 m) containing one MadgeTech PRTemp110 recorder were shipped Priority Overnight by FedEx from East Lansing, Michigan. For 6 weeks, two test packages were …

Measurement And Analysis Of ‘Small’ Packages In Next-Day Air Shipments, Sher Paul Singh, Jay Singh, K. C. Chiang, K. Saha

Industrial Technology and Packaging

Packaged goods are shipped globally using various means of transportation. Over the past two decades, there has been a continuous increase in studies that measure and analyze dynamic events that occur to packages during transportation and handling. These data offer useful information to design and test packages, and provide protection from potential hazards like drops and impacts. However, none of the past studies are directed towards single packages regarded as 'smalls'. 'Smalls' or small-package product systems are defined as those with volume of less than 0.013 m³, a longest dimension of 0.356 m and a weight of 4.54 …

E.J. Gallo Winery Spirit-Makers Facility, Aaron Pickar

Industrial and Manufacturing Engineering

With growing demand for E.J. Gallo spirit brands, the cramped and cluttered facility allocated to the spirit-makers does not provide an adequate work environment to design and test new hard alcohols. E.J. Gallo Winery wants to relocate the spirit-makers to a new facility located near the brandy production floor for under 200,000 dollars. In order to do this, a revised systematic approach to facility design is used.

In this process, the departments are first defined, then the relationships between these departments and the space requirements are documented. Once these planning steps are complete, alternative layouts are constructed and analyzed until …

Implementing Rfid To Improve Animal Shelter Inventory And Allocation, Adam Mach

Industrial and Manufacturing Engineering

The purpose of this project is to observe the best way to incorporate Radio Frequency Identification (RFID) technology into the animal inventory system present in animal shelters, while also observing the benefits of implementing this system. The Woods Humane Society was used in this project as a sample animal care facility that could benefit from this application.

Many RFID systems can be observed in other industries, but very few examples this technology exist in animal shelters or smaller animal care facilities. Part of the reason for that is because funds are scarce at most animal care facilities, like the Woods …

Accidents Will Happen. Do Safety Systems Improve Warehouse Safety Performance?, Rene B. M. De Koster, B. M. Balk, I Davelaar, M. Martens

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Safety is becoming more and more an issue in warehouses. In the literature, effective measures leading to increased occupational health and safety have hardly been researched. Most research focuses on the impact of perceived safety-related leadership of managers and worker safety consciousness on ‘safety climate’ and workers’ safe behavior. We have carried out exploratory research into which measures really improve the safety performance of a warehouse. We particularly focus on the effects of (1) safety-related work procedures, (2) safety leadership, and (3) workers’ safety consciousness. Based on a survey we show that safety leadership and safety-related work procedures significantly drive …

Optimizing The Rearrangement Process In A Dedicated Warehouse, Hector J. Carlo, German E. Giraldo

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Determining the optimal storage assignment for products in a dedicated warehouse has been addressed extensively in the Facility Logistics literature. However, the process of implementing a particular storage assignment given the current location of products has not received much attention in the existing literature. Typically, warehouses use downtime or overtime to remove products from their current location and move them to the suggested location. This work presents the Rearrange-While-Working (RWW) policy to optimize the process of rearranging a dedicated warehouse. The RWW policy seeks to relocate products in a warehouse from the initial arrangement to the optimal arrangement while serving …

A New Milp Approach For The Facility Layout Design Problem With Rectangular And L/T Shaped Departments, Yossi Bukchin, Michal Tzur

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

In this paper we propose a new approach for the facility layout problem (FLP) and suggest new mixed-integer linear programming (MILP) formulations. The proposed approach considers simultaneously the location of the departments within the facility and the internal arrangement of the machines. Two models are suggested, where the first addresses the rectangular department case and the second allows nonrectangular departments defined by an L/T shape. New regularity constraints are developed to avoid irregular department shapes.

Strategic Design Of A Robust Supply Chain, Marc Goetschalckx, Edward Huang

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

The strategic design of a robust supply chain has as goal the configuration of the supply chain structure so that the performance of the supply chain remains of a consistently high quality for all possible future scenarios. We model this goal with an objective function that trades off the central tendency of the supply chain profit with the dispersion of the profit as measured by the standard deviation for any value of the weights assigned to the two components. However, the standard deviation, used as the dispersion penalty for profit maximization, has a square root expression which makes standard maximization …

Evaluating The Effect Of Operational Conditions And Practices On Warehouse Performance, Andrew L. Johnson

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Analyzing warehouse performance across different environments is critical to improving overall productivity and reducing costs. Although two-stage DEA estimators have been shown to be statistically consistent, the finite sample bias of DEA in the first stage carries over to the secondstage regression, which causes bias in the estimated coefficients of the contextual variables. The bias is particularly severe when the contextual variables are correlated with inputs. To address this shortcoming, we apply insights from Johnson and Kuosmanen (2010), who demonstrate that DEA can be formulated as a constrained special case of the Convex Nonparametric Least Squares (CNLS) regression to develop …

Comparing Transport Policies In A Full-Scale 300mm Wafer Manufacturing Facility, J. E. Kiba, S. Dauz`Ere-P´Er`Es, C. Yugma, G. Lamiable

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

Research in semiconductor manufacturing ideally wants to determine the “best” transport policy to ensure continuous production. Determining such a policy is difficult because it depends on many factors such as the layout, the product types, the equipment, etc. Most of the transport policies found in the literature combine dispatching policies (scheduling of transport requests) and routing policies (selection of the path to move from one point to another). This paper investigates a policy called "minimum service" which consists in keeping a minimum number of available vehicles in bays, so that they can quickly answer transport requests and empty travel times …

The Human-Centric Warehouse, Kevin R. Gue

11th IMHRC Proceedings (Milwaukee, Wisconsin. USA – 2010)

In theory and in practice, the objective of warehouse design has long been to meet operational requirements of throughput and service performance at minimum cost. A natural product of this “bottom line” approach has been warehouse buildings and operations ill-suited to the humans who spend their working lives interacting with them. We offer an explanation for the current approach, and argue that a new approach— a new paradigm —is needed. We then describe a comprehensive approach to warehouse design that includes human well-being as a primary goal.
