Mature Oil Fields And Real Options Valuation: Simulation In The

Brazilian Oil Industry

Carlos Abreu, Adjunct Professor, Federal University of Rio Grande

do Norte State (UFRN), Avenida das Brancas Dunas, Natal,

Real Option Valuation in the Oil industry is an important tool for decision-making

valuating a potential flexibility caused by the uncertainties in oil projects. Mature

fields are a considerable portion of producing oil fields around the world. These

oil fields production projects need positive future expectations regarding oil prices

to get a positive investing decision. The Real Options models valuates the decision

to wait for better expectation in prices. In this paper we have a Real Options

analysis in two simulations for mature oil field in the northeastern of Brazil

applying a decision-making rule using Real Options Valuation, net present value

and return on investment indicator.

Class-based Warehouse Location Allocation For Textile Products

This study focuses on building a layout plan by allocating storage space to

products in a warehouse of a textile company (English Home) which allows for

the minimum total travel distance of operators for order picking or placing. The

study is carried out by (1) performing regression analysis for sales forecasting for

each product class, (2) applying Analytical Hierarchy Process for determining

product class weights, and (3) formulating and solving a linear program to

minimize the weighted total distance between storage locations, collecting area,

and loading dock using GAMS. Optimal solution results in 26.8% less distance

required for order picking than the previous layout.

Application Of Advanced Analytics In Banking Big Data

Mou Dutta, Genpact Analytics & Reserach, Danbury, CT,

mou.dutta@genpact.com

Data is meaningful when it delivers insights. Data analysis is smart when insights

are actionable. In today’s world big data and analytics is transforming the business

end to end with smart intelligent insights challenging the conventional thought

process and enabling the marketers to optimize strategies to build a genuine

customer connect and cultivate a positive relationship. This presentation aims to

highlight how marketers are shifting their attention to the application of cutting

edge advanced analytics solutions to gain in-depth knowledge of consumer

buying preferences and product affinity and hence optimize existing cross selling

and up selling marketing strategies.

Efficient Algorithm To Improve Scheduling Problem Solutions

Golshan Madraki, Ohio University, Athens, OH,

g.madraki@gmail.com

Any choice-free manufacturing system can be represented by a directed acyclic

graph (DAG) where the nodes and edges represent the operations, the sequence

of the operations, and with the scheduling of the jobs respectively. Graphical wise,

perturbation may occur over structure of the graph denoting scheduling or

sequencing of operations. The goal of current research is to find the efficient

algorithms to calculate changes to the makespan in a system under multiple

structural perturbations. The paper will show that there will be savings in the

complexity of the calculations if the perturbations are not extensive. As an

example, a buffered job shop system is considered.

Comparing Two Goods-to-person Order Picking Systems For

Online Retailing

Francisco Jose Aldarondo, University of Michigan, Ann Arbor, MI,

faldaron@umich.edu

Using simulation modeling and an on-line retail setting, we compare the

performance of two types of goods-to-person order picking (OP) systems, namely,

the Kiva system and the Miniload-AS/RS with a conveyor loop (to connect the

pick stations). The two systems are compared on the basis of quantitative factors

such as expected throughput (line items picked per hour), expected picker and

material handling equipment utilizations, and order completion times. We also

compare the two systems in terms of qualitative factors that are relevant for OP

systems.

Two-dimensional Cutting Problem And Pallet Loading Problem

Using Industrial Robots

David Alvarez Martinez, Los Andes University, Colombia, Bogotá,

, Guillermo A. Camacho

Muñoz

We developed an automatic cutting and palletizing system, solving the two-

dimensional single knapsack problem and the distributor’s pallet loading problem.

The system is composed by: optimization stage, code-generator, manipulator and

plasma cutter (vacuum gripper). At the optimization we use a GRASP algorithm;

at the code generation we use the forward kinematic model (FKM) of the

manipulator. The GRASP was validated by using the classical benchmarks. The

FKM was validated using the simulator and the controller provided by the Robot

vendor. Finally, we enhanced the cutting procedure through a post-processing. It

reduces the time and keeps the accuracy, but increases particulate generation.

Meaningful Use Of Health Information Technology And Process

Quality Of Care At Hospitals: A Patient Safety Culture Perspective

Based on the Resource Based View and Sociotechnical System Theory, we

examined the synergetic effect of meaningful use of health information

technology (IT) and patient safety culture on hospital quality of care performance.

Hospital safety culture was measured using composite score derived from

confirmatory factor analysis. Health IT meaningful use was measured as

composite index of nine meaningful use criteria with patient days as weights. We

analyzed data from 305 nonfederal acute care hospitals using two-step Heckman

estimation approach and adjusting for autocorrelation in performance outcomes.

Our results show empirical support for the hypothesized relationship.

Gait Assessment: Correlation Of Gait Parameters With Falls

Among Patients With Cognitive Impairment

Idil Arsik, Georgia Institute of Technology, 765 Ferst Drive,

In aging, alteration in the customarily stable gait pattern is one of the most

consistent predictors of falls. Adults with cognitive impairment fall 5x more than

their cognitive intact peers. In this study, we assess the correlation between gait

characteristics captured by gait mat technology and history of falls among patients

with Mild Cognitive Impairment and Alzheimer’s Disease diagnoses.

On Optimization Of Carbon Capture, Utilization, And Storage

Supply Chains Under Uncertainty

Mahnaz Asghari Khankandi, Virginia Tech, Blacksburg, VA, 24060,

United States,

mahnaz@vt.edu

Carbon capture, utilization, and storage (CCUS) is a crucial technology to mitigate

climate change. Due to the high costs of the technology, a great deal of attention

has been focused on how the captured Co2 can be optimally utilized or stored.

We study optimizing CCUS supply chains under an uncertain environment. In

this poster, we present an algorithm to generate a candidate network for Co2

transportation and a model for optimizing the utilization and storage of the

captured Co2 in CCUS systems.

Ethanol Risk Management Modeling

Iddrisu Awudu, Quinnipiac University, 12 Kaye Plaza, Apt E-22,

Hamden, CT, 06514, United States,

iddrisu.awudu@quinnipiac.edu

A theoretical model is developed including margins and risk is measured using

value at risk (VaR). An empirical model is developed and extended to VaR using

copulas to analyze the marginal distribution and dependence structure for input

and output prices on margins. Efficient frontier curves analyzing VaR with and

without copula are discussed. The results compare varying risk-strategy measures

for long corn, short corn, and combining short and long corn. Sensitivity analyses

are conducted for functional changes in the margin as a result of ethanol price

changes.

A Location Allocation Model For Facility Planning To Minimize

The Operational Cost

Damitha Bandara, Dr., Albany State University, 2805, Albany, GA,

31721, United States,

damithb@g.clemson.edu

Locating and allocating distribution centers optimally is a crucial and systematic

task for decision-makers. Optimally located distribution centers can significantly

improve the logistics system’s efficiency and reduce its operational costs. In this

research, we develop a mathematical model to determine the optimal locations

and allocations for distribution centers that minimizes the operational cost. The

model is used to find the optimal location and allocation of distributions centers

for a leading company in the USA. Computational results show that the company

can reduce their operational cost significantly by implementing new optimal

distribution locations.
