Decision Support System


Decision support system (DSS) is an information system that supports business or organizational decision-making activities. DSSs serve the management, operations and planning levels of an organization (usually mid and higher management) and help people make decisions about problems that may be rapidly changing and not easily specified in advance—i.e. unstructured and semi-structured decision problems. Decision support systems can be either fully computerized or human-powered, or a combination of both.

DSS include knowledge-based systems. A properly designed DSS is an interactive software-based system intended to help decision makers compile useful information from a combination of raw data, documents, and personal knowledge, or business models to identify and solve problems and make decisions.

Typical information that a decision support application might gather and present includes
·         inventories of information assets (including legacy and relational data sources, cubes, data warehouses, and data marts),
·         comparative sales figures between one period and the next,
·         projected revenue figures based on product sales assumptions

Decision support systems are interactive, computer-based systems that aid users in judgment and choice activities. They provide data storage and retrieval but enhance the traditional information access and retrieval functions with support for model building and model-based reasoning. They support framing, modeling, and problem solving. Typical application areas of DSS are management and planning in business, health care, the military, and any area in which management will encounter complex decision situations. Decision support systems are typically used for strategic and tactical decisions faced by upper-level management decisions with a reasonably low frequency and high potential consequences in which the time taken for thinking through and modeling the problem pays off generously in the long run.

DSS is an application that produces comprehensive information. This is different from an operations application, which is used to collect data. A DSS is primarily used by mid- to upper-level management and is key for understanding large amounts of data. For example, a DSS may be used to project a company's revenue over the upcoming six months based on new assumptions about product sales. Due to a large number of variables that surround projected revenue figures, this is not a straightforward calculation that can be done manually. A DSS can integrate multiple variables and generate an outcome and alternate outcomes, all based on the company's past product sales data and current variables.

Artifical Neural Network

Artificial Neural Network  is a computational model based on the structure and functions of biological neural networks. Information that flows through the network affects the  a neural network changes or learns, based on that input and output. So the point is  to create a computational system that could solve problems like a human brain. The Neural Networks was founded by  Warren McCulloch and Walter Pitts in 1943. Then it was upgraded with AI (Artificial Intelligence) in 1975 by Kunijiko Fukushima called Artificial Neural Network (ANN) .   Warren McCulloch and Walter Pitts Today  Neural Networks are important in information age, because help society to solve complex problems in real life condition. They can learn from model the relationships between inputs and outputs that are nonlinear and complex; make generalizations and inferences; reveal hidden relationships, patterns and predictions (such as financial time series data) and varianc...

RFM in Business Strategy

RFM Analysis For Successful Customer Segmentation Analysis RFM in Big Data RFM (Recency, Frequency, Monetary) analysis is a proven marketing model for behavior based customer segmentation. It groups customers based on their transaction history – how recently, how often and how much did they buy. RFM helps divide customers into various categories or clusters to identify customers who are more likely to respond to promotions and also for future personalization services. RFM analysis evaluates which customers are of highest and lowest value to an organization based on purchase recency, frequency, and monetary value, in order to reasonably predict which customers are more likely to make purchases again in the future. What are Recency, Frequency and Monetary? ·         Recency      : How much time has elapsed since a customer’s last activity or transaction with the brand. ·     ...

A Thing called Ransomware

A Thing called Ransomware Ransom malware, or   ransomware , is a type of malware that prevents users from accessing their system or personal files and demands ransom payment in order to regain access. The earliest variants of ransomware were developed in the late 1980s, and payment was to be sent via snail mail. In this day, ransomware authors order that payment be sent via cryptocurrency or credit card. There are several different ways that ransomware can infect your computer. One of the most common methods today is through malicious spam, or  malspam , which is unsolicited email that is used to deliver malware. The email might include booby-trapped attachments, such as PDFs or Word documents. It might also contain links to malicious websites. Malspam uses  social engineering  in order to trick people into opening attachments or clicking on links by appearing as legitimate—whether that’s by seeming to be from a trusted institution or a friend. Cybercriminals...
