Demantra forecasting models -Part1

Demantra spectrum product has a set of various mathematical models geared up for capturing various demand patterns. It utilizes Bayesian modeling technique to combine the result of forecast generated by individual 15 mathematical models. The final forecast doesn't merely represents results based on prediction done by just selecting a mathematical model which can best fit the historical pattern of demand. Demantra's patented Bayesian modeling forecasting engine, instead captures the qualitative prediction done by multiple models and thus resulting in one of the best forecasting results in industry.

Oracle's Demantra Demand Management module only provides 9 basic mathematical models and 6 configurable Causal Factors, rest of the 6 advanced statistical models and flexibility of creating unlimited Casual Factors are given away with Advanced Forecasting & Demand Modeling (AFDM) module.

Demand Management module's forecast library has following set of models for usage:
1. Regression
2. Transformation Model(log)
3. Regression for Intermittent
4. Holt
5. Croston for Intermittent
6. Combined Transformation Model(elog)
7. Multiplicative Monte Carlo Regression(CMReg)
8. Integrated Causal Exponential Model(BWint)
9. Auto & Linear Regression

Let's try to get a feel of what are these models and how they work ?
1. Regression: These models are statistical models which are capable enough of describing the variation(trend/pattern) one or more variable(s), based on the variation of one or more other variable(s). Inferences based on this kind of methodology are known as Regression analysis.
e.g. Variation of Demand of a product in market based on time variation.

2. Transformation Model(log): Log transformation model utilizes the log function which squeezes the large values of data together and stretches the small values apart, thus leading to correction data issues like skewed data, outliers and unequal variation.
e.g. Normally demand data has various such problems, the log transformation model tries to minimize those.

3. Regression for Intermittent: This model uses regression analysis for intermittent kind of data. There are parameters related to defining intermittent part of data in the application.

4. Holt: An extension of exponential smoothing can be used when time-series data exhibits a linear trend.

5. Croston for Intermittent: Croston’s Intermittent Model is specifically designed to deal with sporadic demand (no seasonality) with a two-step process. Croston’s Intermittent model recognizes both : the demand size and the demand occurrence.

Downloading Demantra - Too many choices

Demantra under Oracle brand name has now completed more than 18 months and by now Oracle has released three versions of product with Oracle name on it. Oracle's E-delivery site as of today shows following list of products:

The latest release is 7.2 and is only 2 weeks old. Previous releases are 7.1.1 which now is 6 months old and quite a few implementation of this version are either completed or are towards completion phase. 7.1.0.1 version was the first release made by Oracle, which is more of an Oracle christened Demantra product.

Which one I need?

There are lot many factors which will drive this decision, but the differentiators here in terms of integration offered by Oracle will be a key to decision making.

- Demantra 7.2: For business which wants to do an integrated S&OP using Demantra spectrum.

- Demantra 7.1.1: For those who want to have just the basic Demand Planning environment to start with, but need the integration with EBS.

- Demantra 7.1.0.1: For stand alone Demantra installation.

As per standard practise, it is always recommended to go for the latest version of product when it comes to buying licence of a product. But again points like stability of a release, industry examples, need of business and budget etc. play a vital role in making a call.

Oracle Demantra's 7.2 version has brought three major seeded integration and also with this release Oracle has first time revealed three other Demantra modules with Oracle flavor. The list compromises of Real time Sales & Operations Planning, Predictive Trade Planning & Deduction Settlement Management. All these modules were available earlier as well in Demantra Spectrum, but now in 7.2 release Oracle has provided integrated versions of these with it's ERP applications. S&OP has got integrated with Oracle EBS and APS modules, while PTP(Predictive Trade Planning) & DSM(Deduction Settlement & Management) modules have been integrated with JD Edwards Enterprise One(JDE E1).

S&OP integration comes in line with the earlier release 7.1 where Oracle integrated Demand Management module of Demantra with Oracle's EBS & JDE E1. Oracle Demantra Demand Management offered an out of box configured web based collaborative demand planning environment for achieving best in class, unconstrained accurate forecast. This unconstrained consensus forecast was then available for being referred and used by down the line Supply chain components and ERP system for supply planning.
S&OP integration on top of it, empowers you to bring in all the capacity & material constraints with all the supply plan information into Demantra application. The inbound integration in 7.2 has grown to ASCP(Advanced Supply Chain Planing) & SNO(Strategic Network Optimization) modules, along with EBS. This seeded integration fetches in supply chain intelligence information & cost data too, for being utilized in S&OP process. Outbound seeded integration available in this release are to ASCP, SNO, IO(Inventory Optimization) & PS(Production Scheduling).

Demantra Application - Components

Demantra has two set of applications, one which are Browser based applications and others which are desktop based. Typically used Demantra applications are:

1. Browser based applications: These applications provide a web-based collaborative environment with a customizable and user-friendly user interface. Most used applications in this category are Collaborator Workbench, Workflow Management and Demand Planner Anywhere

2. Client based applications: Desktop applications are used mostly by only few key users as these applications serve as administrative tools. Few important ones in this category are Business Modeler, Demand Planner, Scheduler, Engine Administrator etc.

Basic Components of Demantra:
Worksheets: This is an online working environment provided for viewing and editing data. Worksheets are created for supporting need of specific business functions/processes. The worksheet application is the environment on which a demand planner/analyst works for most of the hours of his day.

Workflow: A browser based application for executing functions and processes from front end. This act as a software process which can be utilised to support complex processes & flows and also can automate it.

Content Panes: Dashboards with graphical or tabular views in a read only format, to present all the information on your fingertips. Content Panes become very handy for Executives and Managers for information which can be fetched from the worksheets and represent KPIs.

Collaborator Workbench: Browser based collaborative workbench environment which serves as a launch pad for various applications as well as for quick information & updates with access to KPIs. Workbench can be personalized for each business user as per their needs and roles.

Analytical Engine: Forecasting Engine which generates forecast using Bayesian modeling technique by utilizing multiple statistical models(number depends on licence).
