Progressive Approach to Modeling: Modeling for decision making involves two distinct parties, one is the decision-maker and the other is the model-builder known as the analyst. Therefore, the analyst must be equipped with more than a set of analytical methods.

Specialists in model building are often tempted to study a problem, and then go off in isolation to develop an elaborate mathematical model for use by the manager i.

Unfortunately the manager may not understand this model and may either use it blindly or reject it entirely. The specialist may feel that the manager is too ignorant and unsophisticated to appreciate the model, while the manager may feel that the specialist lives in a dream world of unrealistic assumptions and irrelevant mathematical language.

Such miscommunication can be avoided if the manager works with the specialist to develop first a simple model that provides a crude but understandable analysis.

After the manager has built up confidence in this model, additional detail and sophistication can be added, perhaps progressively only a bit at a time. This progressive model building is often referred to as the bootstrapping approach and is the most important factor in determining successful implementation of a decision model.

Moreover the bootstrapping approach simplifies otherwise the difficult task of model validating and verification processes. What is a System: Systems are formed with parts put together in a particular manner in order to pursuit an objective.

The relationship between the parts determines what the system does and how it functions as a whole. Therefore, the relationship in a system are often more important than the individual parts.

Tools for Decision Analysis

In general, systems that are building blocks for other systems are called subsystems The Dynamics of a System: A system that does not change is a static i.

Many of the systems we are part of are dynamic systems, which are they change over time. Whether a system is static or dynamic depends on which time horizon you choose and which variables you concentrate on. The time horizon is the time period within which you study the system.

The variables are changeable values on the system. In deterministic modelsa good decision is judged by the outcome alone.

However, in probabilistic models, the decision-maker is concerned not only with the outcome value but also with the amount of risk each decision carries As an example of deterministic versus probabilistic models, consider the past and the future:Get the latest news and analysis in the stock market today, including national and world stock market news, business news, financial news and more.

An information system (IS) is an organized system for the collection, organization, storage and communication of specifically, it is the study of complementary networks that people and organizations use to collect, filter, process, create and distribute data.

The global financial system is the worldwide framework of legal agreements, institutions, and both formal and informal economic actors that together facilitate international flows of financial capital for purposes of investment and trade emerging in the late 19th century during the first modern wave of economic globalization, its evolution is .
