Development Of A Systems Engineering Model Of The Chemical Separations Process, Yitung Chen, Darrell Pepper, Sean Hsieh
Separations Campaign (TRP)
The chemical processing of used nuclear fuel is an integral component of any strategy for the transmutation of nuclear waste. Due to the large volume of material that must be handled in this first step of the transmutation process, the efficiency of the separations process is a key factor in the potential economic viability of transmutation strategies. The ability to optimize the chemical separation systems is vital to ensure the feasibility of the transmutation program.
Systems analysis, or total systems modeling, is one of the strongest tools available to researchers for understanding and optimizing complex systems such as chemical separations ...

We review a large multidisciplinary effort to develop a family of autonomous robots capable of rapid, agile maneuvers in and around natural and artificial vertical terrains such as walls, cliffs, caves, trees and rubble. Our robot designs are inspired by (but not direct copies of) biological climbers such as cockroaches, geckos, and squirrels. We are incorporating advanced materials (e.g., synthetic gecko hairs) into these designs and fabricating them using state of the art rapid prototyping techniques (e.g., shape deposition manufacturing) that permit multiple iterations of design and testing with an effective integration path for the novel materials and ...

This paper proposes a new network centric architecture that can be used by first responders to effectively respond to crisis situations. The powerful networkcentric concept originally developed for and mainly used in the military environment, can be effectively used for civilian security and emergency response missions. This paper also proposes the use of a swarm of intelligent robots as a part of the networkcentric architecture to aid the first responders. The swarm of robots works in tandem with the first responders and provides them with the necessary information on a real time basis. The proposed network centric architecture with a ...

We initiate a study of mathematical models for specifying (discrete) simulationbased control systems. It is desirable to specify simulationbased control systems using a model that is intuitive, succinct, expressive, and whose state space properties are relatively easy computationally. We compare automatabased models for specifying control systems and find that all systems that are currently used (such as finite state machines, communicating hierarchical finite state machines (FSM), communicating finite state machines, and Turing machines) lack at least one of the abovementioned features. We propose using sequential dynamical systems (SDS)  a formalism for representing discrete simulations  to specify simulationbased control systems. We ...

Allocating Work In Process In A MultipleProduct Conwip System With Lost Sales, Sarah M. Ryan, Jumpol Vorasayan
Industrial and Manufacturing Systems Engineering Publications
To operate a multipleproduct manufacturing system under a CONWIP control policy, one must decide how to assign kanbans to products. With a fixed total number of kanbans in a competitive environment, the goal is to determine their allocation to product types in order to minimize lost sales equitably. In particular, we consider systems in which the products may make multiple visits to the same station with a different processing time distribution on each repeat visit. With a fixed number of kanbans dedicated to each product, the system is modeled as a multiplechain multipleclass closed queuing network. A nonlinear program simultaneously ...

On The Validity Of The Geometric Brownian Motion Assumption, Rahul Ratnakar Marathe, Sarah M. Ryan
Industrial and Manufacturing Systems Engineering Publications
The geometric Brownian motion (GBM) process is frequently invoked as a model for such diverse quantities as stock prices, natural resource prices and the growth in demand for products or services. We discuss a process for checking whether a given time series follows the GBM process. Methods to remove seasonal variation from such a time series are also analyzed. Of four industries studied, the historical time series for usage of established services meet the criteria for a GBM; however, the data for growth of emergent services do not.
LikelihoodBased Statistical Estimation From Quantized Data, Stephen B. Vardeman, ChiangSheng Lee
LikelihoodBased Statistical Estimation From Quantized Data, Stephen B. Vardeman, ChiangSheng Lee
Industrial and Manufacturing Systems Engineering Publications
Most standard statistical methods treat numerical data as if they were real (infinitenumberofdecimalplaces) observations. The issue of quantization or digital resolution can render such methods inappropriate and misleading. This article discusses some of the difficulties of interpretation and corresponding difficulties of inference arising in even very simple measurement contexts, once the presence of quantization is admitted. It then argues (using the simple case of confidence interval estimation based on a quantized random sample from a normal distribution as a vehicle) for the use of statistical methods based on "rounded data likelihood functions" as an effective way of handling the matter.

Sheppard's Correction For Variances And The "Quantization Noise Model", Stephen B. Vardeman
Industrial and Manufacturing Systems Engineering Publications
In this paper, we examine the relevance of Sheppard's correction for variances and (both the original and a valid weak form of) the socalled "quantization noise model" to understanding the effects of integer rounding on continuous random variables. We further consider whether there is any real relationship between the two. We observe that the strong form of the model is not really relevant to describing rounding effects. We demonstrate using simple cases the substantial limitations of the Sheppard correction, and use simple versions of a weak form of the model to establish that there is no real connection between ...

Likelihood And Bayesian Methods For Accurate Identification Of Measurement Biases In Pseudo SteadyState Processes, Sriram Devanathan, Stephen B. Vardeman, Derrick K. Rollins Sr.
Industrial and Manufacturing Systems Engineering Publications
Two new approaches are presented for improved identification of measurement biases in linear pseudo steadystate processes. Both are designed to detect a change in the mean of a measured variable leading to an inference regarding the presence of a biased measurement. The first method is based on a likelihood ratio test for the presence of a mean shift. The second is based on a Bayesian decision rule (relying on prior distributions for unknown parameters) for the detection of a mean shift. The performance of these two methods is compared with that of a method given by Devanathan et al. (2000 ...

Light Rail And Brt: Competitive Or Complementary?, Vukan R. Vuchic
Departmental Papers (ESE)
Since the 1970s great progress has been made to develop transit systems which provide service considerably better than buses can offer in mixed traffic, but which require significantly lower investment than metro systems with exclusive ways. This “semirapid transit” category of modes, using mostly partially separated ways, has been introduced extensively in mediumsized cities, as well as supplementing metros in suburban areas of large cities.
