1 - A Lagrangian Relaxation Approach For A Multiproduct Stochastic

Production Planning Problem

We model a single-stage multi item capacitated production-inventory system with

stochastic demand. We present a chance-constrained production planning model

that considers forecast evolution, which is solve using Lagrangian relaxation.

Computational results show that the proposed approach outperforms previous

myopic capacity allocation procedures.

2 - Order Scheduling For A Class Of Electronic Ceramic

Manufacturers In Make To Order Environments

Motivated by the applications for a class of electronic ceramic manufacturers, we

study the order scheduling on sintering operations in make-to-order

environments, where sintering furnaces are modeled as batch processing

machines. The order consists of multiple types of jobs with specific demand

quantity. We consider the total weighted order completion time as objective

function and prove the problem is strongly NP-hard. Efficient heuristics with

worst-case analysis and asymptotic performance analysis are also developed.

Numerical results demonstrate that the proposed heuristics can give near-optimal

solutions for different production scenarios.

3 - A Lagrangian Approach For Coordinating Capacity Negotiations

In A Semiconductor Firm

We model the negotiations between a product development organization and a

production organization for access to manufacturing capacity for product

development activities in the semiconductor industry. We develop a negotiation

framework based on Lagrangian decomposition that maximizes overall firm

contribution subject to the resource constraints of both organizations. The

approach aims to achieve coordinated decisions between the two organizations,

and provides a benchmark for alternative models of negotiations.

4 - Modeling And Solution For Supply Chain Scheduling In

This paper studies a supply chain scheduling problem which is derived from steel

production. The problem is to make coil schedules with the aim of balancing the

capacity of each production line, and minimizing the total setup cost. To describe

the problem, we formulate a MILP model with consideration of practical

technological requirements. Then we develop an improved discrete differential

evolution (DE) algorithm to solve it. The computational experiments show that

the proposed DE algorithm outperforms the compared DE algorithms for solving

this problem. In addition, the proposed algorithm is also competitive in

comparison with the commercial optimization solver CPLEX.

5 - Analysis Of The Barriers To Implement Additive Manufacturing

Technology In The Indian Automotive Sector:

A Fuzzy-ISM Approach

This paper analyzes the interaction among barriers to implement additive

manufacturing (AM) technology in the Indian automotive sector. We use Fuzzy-

Interpretive Structural Modeling (Fuzzy-ISM) method to derive hierarchy and

direction and to measure the strength of relations among these barriers.

Dominant barriers are identified using this approach. The findings may be useful

for managers to develop suitable mitigation strategies. This study contributes to

AM literature by the structured presentation of the barriers.

Technologoy Tutorial: Palisade Corporation/Bayesia

1 - Palisade: Introduction To Risk And Decision Analysis Using

@RISK And The Decision Tools Suite

José Raúl Castro, Palisade Corporation, Ithaca, NY,

raul.castro.gc@gmail.com

This software presentation is designed to provide an entry-level introduction into

probabilistic analysis and will show how Monte Carlo simulation and other

techniques can be applied to your everyday business analyses. Using Monte Carlo

simulation, @RISK will analyze many different scenarios all at once, giving you

more insight into what could happen. We’ll look at example models including a

basic revenues/cost/profits model, an NPV model, and a Cost Estimation model, to

give you an idea of how quickly you can get started in probabilistic modeling in

Excel. If you build models in Excel then Palisade solutions can almost certainly

help you to make more informed decisions, right from your desktop. Palisade

software and solutions have been used to make better decisions. Cost estimation,

NPV analysis, operational risk registers, portfolio analysis, insurance loss

modeling, reserves estimation, schedule risk analysis, budgeting, sales forecasting,

and demand forecasting are just some of the ways in which the tools are applied.

This presentation will demonstrate how easy - and necessary - it is to implement

quantitative risk analysis in any business.

2 - Bayesian Networks & BayesiaLab: Artificial Intelligence for

Research, Analytics, and Reasoning

Stefan Conrady, BAYESIA USA, Franklin, TN, Contact:

The objective of this workshop is to show that “Artificial Intelligence” should not

be perceived as a quasi-magic technology that is mostly incomprehensible to

normal mortals. We want to illustrate how scientists in any field of study—rather

than only computer scientists—can employ AI to explore complex problems. For

this purpose, we present Bayesian networks as the framework and BayesiaLab as

the software platform. In this context, we demonstrate BayesiaLab’s supervised

and unsupervised machine learning algorithms for knowledge discovery in high-

dimensional, unknown domains. Also, while AI is commonly associated with

another buzzword, “Big Data”, we wish to prove that AI can be useful for dealing

with problems for which we possess little or no data. Here, expert knowledge

modeling is critical, and we describe how even a minimal amount of expertise can

serve as a basis for sound reasoning aided by AI.

1 - Group-wise Sufficient Dimension Reduction: With Applications In

Forecasting The Equity Risk Premium

Haileab Tesfe Hilafu, University of Tennessee,

hhilafu@utk.edu

When there is prior domain knowledge concerning a grouping structure of the

predictors, two different approaches of dimension reduction exist: carry out

dimension reduction of predictors in each group separately which ignores the

inter-dependence among the groups; ignore the grouping structure and reduce

the dimension of the predictors jointly. We present a method that bridges these

two approaches in the sense that it, simultaneously, utilizes the prior domain

knowledge and accounts for potential inter-dependence among the groups of

predictors. The proposed method is applied to forecast the equity risk premium

from a set of well known macroeconomic and a set of technical variables.

2 - Sufficient Dimension Reduction For Treatment Effect Estimation

, Wenbo Wu

For nonparametric methods of estimating the treatment effect, if the dimension of

the baseline covariates is large, implementation becomes difficult and sometimes

infeasible due to the curse of dimensionality. Hence, sufficient dimension

reduction of baseline covariates can be useful before estimating the treatment

effect. We refer to such a dimension reduction subspace as a central treatment

effect subspace (CTES). We propose methods to estimate the CTES and its

structural dimension, investigate the theoretical properties of these estimators,

and demonstrate their effectiveness with numerical studies.
