Social learning and networking have also become important aspects of e-learning, allowing students to learn from each other.
This document discusses how the presenter, a PhD student, uses AWS for high performance modeling in his research on financial capital structure. He first provides an overview of his research question on explaining how firms use debt and equity to finance themselves. He then presents a mathematical model of the firm's optimization problem. Solving this model is challenging due to the curse of dimensionality. The presenter explains how he uses AWS to overcome this by parallelizing the value function iteration algorithm across many compute instances.

Reimagine your enterprise: Make Human Centered Design the Heart of Your Digit...Kenneth Kwan
Companies in every industry are trying to find new sources of value
through digital technology. But most of their efforts have not translated
into enough market impact and growth. They need something bolder
and more disruptive, but still very simple. They need reimagination.
Reimagination means putting the user at the center of everything
your company does — strategy, product development, operations,
marketing, sales, and customer service. It means using the full power
of digital media and technology to build empathy with that user, and
weaving that relationship into the fabric of your company. This practice
is known as “human centered design” (HCD): the reshaping of an entire
enterprise and its capabilities system around the customer or user
experience.
HCD represents a new way of life for business. It evokes many of the
attributes of a startup — creativity, speed, bias for action, flexibility
with risk, and radical collaboration. To achieve this entrepreneurial
vigor in your company, you may have to consciously break down long
established internal barriers. You must embrace five basic principles:
Embed human centered design in everything you do, build brand value
holistically, design for three years out (but build for today), stand up
new structures and teams, and nurture your existing digital culture.
Flowsheet Decomposition Heuristic for Scheduling: A Relax & Fix MethodAlkis Vazacopoulos
Decomposing large problems into several smaller subproblems is well-known in any problem solving endeavor and forms the basis for our flowsheet decomposition heuristic (FDH) described in this short note. It can be used as an effective strategy to decrease the time necessary to find good integer-feasible solutions when solving closed-shop scheduling problems found in the process industries. The technique is to appropriately assign each piece of equipment (i.e., process-units and storage-vessels) into groups and then to sequence these groups according to the material-flow-path of the production network following the engineering structure of the problem. As many mixed-integer linear programming (MILP) problems are solved as there are groups, solved in a pre-specified order, fixing the binary variables after each MILP and proceeding to the next. In each MILP, only the binary variables associated with the current group are explicit search variables. The others associated with the un-searched on binary variables (or the next in-line equipment) are relaxed. Three examples are detailed which establishes the effectiveness of this relax-and-fix type heuristic.

Time Series Estimation of Gas Furnace Data in IMPL and CPLEX Industrial Model...Alkis Vazacopoulos
Presented in this short document is a description of how to estimate a deterministic and stochastic time-series transfer function models in IMPL using IBM’s CPLEX applied to industrial gas furnace data. The methodology of time-series analysis involves essentially three (3) stages (Box and Jenkins, 1976): (1) model structure identification, (2) model parameter estimation and (3) model checking and diagnostics. We do not address (1) which requires stationarity and seasonality assessment, auto-, cross- and partial-correlation, etc. to establish the transfer function polynomial degrees. Instead we focus only on the parameter estimation and diagnostics. These types of parameter estimation problems involve dynamic and nonlinear relationships shown below and we solve these using IMPL’s nonlinear programming algorithm SLPQPE which uses CPLEX 12.6 as the QP sub-solver.

Social media advertising provides a cheaper way for companies to expand their business and reach a large audience, with platforms like YouTube receiving 1 billion daily views and Facebook having 400 million users. The document discusses how social media advertising can be very profitable for companies by allowing them to reach extensive audiences on major platforms like YouTube, Facebook, MySpace, and Twitter at a lower cost than traditional advertising methods.
The document provides an introduction to Industrial Modeling Language (IML), which allows users to configure data for modeling and solving large-scale industrial optimization problems. It describes how IML data is categorized into quantities, logic, and quality dimensions. The reference manual focuses specifically on configuring quantity data using frames with different features and fields. Frames are similar to sheets in a spreadsheet and are used to apply quantity-logic-quality attributes to unit-operation-port-state superstructure keys. The document outlines several basic frames and their fields for configuring quantity-only problem types.
- Large optimization models are increasingly challenging to solve optimally due to super-linear growth in solving effort as model size increases. Parallel heuristic methods provide good quality solutions within practical time limits by solving smaller submodels simultaneously on multiple processor threads.
- Testing on scheduling, supply chain, and telecommunications models found parallel heuristics found high quality solutions for most models in hours, while optimal solutions were impossible within days for some larger models. However, using too many threads showed diminishing returns and even degradation in solution quality due to memory bus bandwidth limitations.
The document summarizes how the magazine "Retro" attracted and addressed its target audience. It did this through:
1) Including popular artists like Katy Perry and The Beatles that would appeal to the audience's musical tastes.
2) Using strong photography and vintage fonts/styles that related to the interests of the target audience in photography, fashion from the 1950s/60s.
3) Providing quick facts and summaries about artists/music in a concise way that would engage the target audience.
This short quiz consists of 4 questions to test if you are qualified to be a professional. The questions test things like overcomplicating simple tasks, thinking through consequences, memory, and learning from mistakes. Most professionals get all the questions wrong, while preschoolers get several right, disproving the idea that professionals have four-year-old level brains.
Generalized capital investment planning of oil-refineries using CPLEX-MILP an...Alkis Vazacopoulos
Performing capital investment planning (CIP) is traditionally done using linear (LP) or nonlinear (NLP) models whereby a gamut of scenarios are generated and manually searched to make expand and/or install decisions. Though mixed-integer nonlinear (MINLP) solvers have made significant advancements, they are often slow for industrial expenditure optimizations. We propose a more tractable approach using mixed-integer linear (MILP) model and input-output (Leontief) models whereby the nonlinearities are approximated to linearized operations, activities, or modes in large-scaled flowsheet problems. To model the different types of CIP's known as revamping, retrofitting, and repairing, we unify the modeling by combining planning balances with the scheduling concepts of sequence-dependent changeovers to represent the construction, commission, and correction stages explicitly. Similar applications can be applied to process design synthesis, asset allocation and utilization, and turnaround and inspection scheduling. Two motivating examples illustrate the modeling, and a retrofit example and an oil-refinery investment planning are highlighted.
