Introduction to Optimization with Evolver and RISKOptimizer: Comparing Portfolio Allocation with Deterministic versus Stochastic Assumptions

Optimization is a very important tool in business decisions, but there's a huge difference in outcomes if the business environment deviates from the assumptions used to optimize the strategy. In this webinar we will show the difference between deterministic and stochastic optimization, and how we can develop much more robust strategies by accounting for uncertainties in the models.

Stochastic optimization helps integrate both risk analysis and optimization into a single process, generating a decision strategy that is both optimized and robust in face of an uncertain future. We will demonstrate how to perform Portfolio Allocation under a context of uncertainty using stochastic optimization, and compare the resulting decision strategy with the traditional deterministic optimization.

Introduction to Decision Analysis Using PrecisionTree: Maintenance Plan Costs

Decision trees are structured decision models containing sequences of decisions and events. They allow us to graphically map the plan throughout the lifetime of a project, along with uncertain events in the future, managerial flexibilities of the project, and alternative strategies available.

In most projects, there are several ways to gather more information before making an irreversible decision. Information gathering can be a complex process such as market research (in retail and manufacturing) or seismic tests (in oil and gas), or a very simple thing such as waiting for a competitor to launch a product first and measure the market acceptance.

This webinar will demonstrate how to use decision tree models measure the value of information (VOI), both perfect and imperfect, and the consequences it brings to the decision process. All within Excel and in an intuitive way, but with all the necessary mathematical rigor.

Introdução à Otimização com Evolver e RISKOptimizer: Comparando a Alocação de Portfólio com Premissas Determinísticas Versus Estocásticas

A otimização é uma ferramenta muito importante nas decisões de negócios, mas há uma enorme diferença nos resultados se o ambiente de negócios se desviar das premissas usadas para otimizar a estratégia.

Neste webinar vamos mostrar a diferença entre otimização determinística e estocástica, e como podemos desenvolver estratégias muito mais robustas levando em conta as incertezas nos modelos.
A otimização estocástica ajuda a integrar tanto a análise de risco quanto a otimização em um único processo, gerando uma estratégia de decisão otimizada e robusta diante de um futuro incerto.

Demonstraremos como realizar a Alocação de Portfólio sob um contexto de incerteza usando otimização estocástica e compararemos a estratégia de decisão resultante com a otimização determinística tradicional.

Introdução à Otimização com RISKOptimizer: Alocação de Portfólio

Los árboles de decisión son modelos de decisión estructurados que contienen secuencias de decisiones y eventos. Ellos permiten mapear gráficamente el plan a lo largo de toda la vida útil de un proyecto, junto con los eventos inciertos en el futuro, las flexibilidades de gestión del proyecto y estrategias alternativas disponibles.

En la mayoría de los proyectos, hay varias formas de obtener más información antes de tomar una decisión irreversible. La obtención de información puede ser un proceso complejo, como un market research (en comercio o en fabricación) o pruebas sísmicas (en petróleo y gas), o algo muy simple, como esperar a que un competidor lance un producto primero y entonces medir la aceptación del mercado.

Este webinar demostrará cómo usar modelos de árboles de decisión para medir el valor de la información (VOI), tanto perfecta como imperfecta, y sus consecuencias para el proceso de decisión. Todo dentro de Excel y de forma intuitiva, pero con todo el rigor matemático necesario.

1 - Construcción básica de modelos de árboles de decisión
2 - Modelado de alternativas e información
3 - Interpretación del modelo y cálculos
4 - Análisis de sensibilidad y herramientas para modelos complejos
5 - Formas avanzadas de modelar riesgos e incertidumbres

Introducción al Análisis de Decisiones con PrecisionTree:Valor de la Información

Whether of raw material, intermediate or final product, human or financial resource, or even resources such as hotel rooms and seats on a plane, inventory is a fact of life for the service and manufacturing industries. Most introductory courses in operations research or management science present analytical models (e.g., EOQ) to assist with the related inventory decisions of how much and how often to order in a manner that minimizes total inventory-related costs. If the assumptions behind these models hold they can prove very useful. When the assumptions don’t hold however, simulation is appropriate. Recent experience with supply chain disruptions and customer demand during turbulent economic times should have woken all who work with inventory to the difficulties presented by uncertain demand and order lead time, making most analytical inventory system models, where both demand and lead time are assumed to be constant, inappropriate.

Following a brief discussion of several basic inventory system analytical models and their associated assumptions, this webinar will present @RISK models for simulating inventory systems that handle lost sales and back orders while treating demand and lead time as uncertainties. Several additional embellishments will then be discussed to account for situations where further analytical model assumptions don’t hold.

Modeling Inventory Systems with @RISK: Lost Sales and Back Orders

This webinar presents an introduction on using Monte Carlo Simulation to perform Quantitative Risk Analysis.

On this last webinar of the O&G series we will wrap up everything we presented so far: based on the risk analysis of each project, we will group them in a portfolio and optimize it according to the company's objectives and constraints.

We will discuss which risks are specific to each project (such as its production curve), which risks are systemic to the portfolio (such as crude oil prices), the correct way to model each risk, and the effects of correlations.

Oil & Gas Webinar Series 5: Project Portfolio Analysis and Optimization

On this forth webinar of the O&G series will present how to represent and forecast crude oil prices using time series models. We will use historical data to fit/calibrate a model for spot prices, and then use this model to forecast future prices for the valuation of an E&P project.

Oil & Gas Webinar Series 4: Modeling Commodity Price Risk with Time Series

This is the third webinar of the O&G series, and here will present how to model the uncertainty around drilling times, including a risk matrix and risk drivers such as NPT (non-productive time) and WOW (wait on water). We will also see an example of how to measure the impact of these risks based on historical data.

Bombeo de Agua en Minería: Aprovechando las Diferencias de Precios en Mercado Spot con @RISK.

El mercado spot de electricidad en Chile, ya desde el 2021 ha presentado una característica que ha resultado notoria, diferencias de precios importante en ciertas horas del día, lo anterior originado fundamentalmente por una gran capacidad de generación renovable del tipo fotovoltaica instalada en el sistema eléctrico. Es así como en horas de sol y en la zona del norte de Chile donde operan las principales compañías mineras, el precio del energía o costo marginal del sistema, presenta características del tipo mostrada en la gráfica adjunta la cual corresponde a S/E Crucero nivel 220 kV; más aún en ciertas horas se han presentado precios nulos en determinados días. Destacamos esta subestación tanto por la zona en donde se ubica como al hecho que es la que presenta mayor número de horas con precios nulos, vertimiento, dentro de las principales subestaciones del país.

La existencia de las características en los precios del mercado spot, presenta cualidades que pueden ser aprovechadas por clientes y/o empresas generadoras para una reducción de los costos asociados en el suministro de ciertos procesos mineros que presentan holguras y capacidad de almacenamiento (pulmones). Es así como procesos asociados al bombeo de agua en minería presenta características que permiten aprovechar el perfil de precios mostrado. En el webinar desarrollaremos el análisis de un bombeo de agua típico en Minería, considerando aspectos estocásticos con ayuda de @RISK, como el bombeo de agua y la eficiencia asociada, demanda de agua, fiabilidad del suministro eléctrico como la evaporación del insumo en las piscinas de almacenamiento, al cambiar de un bombeo tradicional a uno que considere una mayor impulsión en horas de sol bajando en terceras horas, de forma de bajar los costos asociados e impulsar el bombeo hacia uno Verde, aprovechando mayor presencia de generación de energía renovable.

Risks, uncertainties and probabilistic decision making in an increasingly volatile engineering & construction – A case study assessing optimum delivery strategy for procuring a major water pipeline project

Post COVID-19, the Engineering & Construction sector is changing fundamentally, leading to significant risk exposure faced by both public and private organizations. Beyond the recent economic uncertainties, more frequent catastrophic events are expected in future, as well as disruptions including climate change, digital revolution, limited capability and capacity, supply chain constraints, social license to operate, stakeholder expectations and political risks. 

One of the best ways to embrace uncertainty in our approach is to learn to think probabilistically, like a professional gambler. Developing a probabilistic mindset allows us to be better prepared for uncertainties, complexities, and different scenarios for making better informed decisions. 

With a global investment of approximately US$60 trillion, including a potential pipeline of $800b projects in Australia over the three decades to 2050 net zero emission targets, across power, mining and metals, hydrogen, carbon capture and oil & gas projects, Pedram believes there are good opportunities for the industry to improve the way it selects, develops, and delivers major projects by better utilizing the risk engineering techniques such as probabilistic decision tree analysis. 

By sharing a recent case study of using a probabilistic decision tree analysis (by using Palisade Decision Tools software) for comparing and selecting the most optimum delivery strategy for procuring a major water pipeline project, Pedram will explain the fundamentals of decision-making process. According to Pedram, organizations that arm themselves with probabilistic thinking and capabilities will become more resilient and put themselves in a much better position to safeguard for uncertainties ahead.

How to account for correlation in price models for commodities?

On this fifth webinar of the Forecasts with Uncertainty Webinar Series we will present how to estimate and forecast prices of groups of correlated commodities - for example, petroleum and its refined products or soy bean, oil and meal. 

Correlation adds an extra layer of complexity when creating realistic forecast models, especially for commodities. We will use historical data to fit, calibrate and simulate correlated time series models for commodities, and discuss some pitfalls and practical insights on modeling.

Forecasts with Uncertainty Webinar Series 5: Forecasting Correlated Commodities

If your cost model includes an Ordinary Least Squares (OLS)-based Cost Estimating Relationship (CER) and you are not explicitly modeling the associated error, for a linear regression you are implicitly assuming that there is no error.  On average that’s a safe assumption; it’s individual occurrences however that can make this risky.  

After a brief review of OLS regression fundamentals (yeah, calculus), this webinar will show how @RISK can be used to model a regression equation’s error term for both linear and nonlinear (intrinsically linear) CERs.  Along the way you will improve your skill working with the normal distribution and, if it’s not already part of it, add the lognormal distribution to your repertoire.
