...Decision Support System (DSS) A Decision Support System (DSS) is an interactive computer-based system or subsystem which is meant for helping out decision makers in using several communications technologies, data, documents, knowledge and/or models for the identification and resolution of a number of problems, completion of tasks related to decision process, and formulation of adequate decisions. The term, Decision Support System is generally used to refer to any computer-based application which is designed to enhance the abilities of a person or a group of individuals in making efficient and effective decisions. In addition to that, Decision Support System is also a frequently explored academic field of research which takes of designing and implementation processes of Decision Support Systems along with the analysis of their areas of application. All in all, Decision Support Systems come under an umbrella of the computerized information system which can effectively manage and support all activities related to effective decision making. There are five more specific types of Decision Support Systems as listed below (DSS Basics): * Communication-driven Decision Support System * Data-driven Decision Support System * Document-driven Decision Support System * Knowledge-driven Decision Support System * Model-driven Decision Support System In general, decision support systems usually gather and present organizational information that help them generating (decision...

...Decision Support Managers in any organization face decision-making scenarios in almost every segment of their operations; whether if it is deciding to use a business-to-business (B2B) commerce model, which security system to use for its IT department, and even deciding on employee benefit plans. The bottom line is organizations cannot be competitive without making crucial decisions. Executives use decision-making systems to enhance their sales because most of their decisions are unstructured or semi structured. Accordingly, they need the best tools to help them. In addition, the more information they have, based on internal experiences or from external sources, the better their decisions. “By combining massive amounts of data with sophisticated analytical models and tools, and by making the system easy to use, they provide a much better source of information to use in the decision-making process” (Studymode.com, 2012) In relation to Information Technology, a decision support system (DSS) is a computer-based, information system intended to assist decision makers in approaching ill-structured problems by offering diagnostic models and access to databases (Haag & Cummings, 2008, pg. 162). Advantages and disadvantages of using decision support systems for decision-making The advantages of using decision support systems are (1) increased productivity, (2) increased understanding, (3) increased speed, (4) increased flexibility, (5) reduced problem complexity, and (6) reduced...

...Decision support systems are a lesson of computer-based information systems plus knowledge based systems which support decision making activities. Since there are numerous methods for decision-making, moreover, because of the wide range of dominions in which decisions are made, thus, the concept of decision support system (DSS) is very wide-ranging. A DSS may take several different formulae. In general, we can assure that a DSS is a computer system in order to aid for making decisions. A decision is an optimal among alternatives based on estimations, valuation and of the standard of those substitutes. However, supporting a decision means assisting employee working alone, or in a group gathers intelligence as teamwork and the best and appropriate for the organization. In addition, supporting the optimal making process involves backup, the appraisal and/or the comparison of alternatives. In practice, references of DSS are commonly references to computer applications that perform by means of supporting role. The decision support system has been well-defined in various ways by different scholars and managers. On contrary, others define a DSS rather mainly is "a computer-based system that aids the process of decision making." For instance, Turban expresses exactly as "an interactive, flexible, and adaptable computer-based information system, specially developed for supporting the solution of a non-structured management problem for improved decision making. It utilizes data, provides...

...Decision Support Systems December 22, 2014 Decision Support Systems Many businesses are faced with situations that need critical analysis, compilation of raw data, circulation of precise documents and effective utilization of computer systems. Frito Lay is an example of a company who implemented various decision support systems (DSS) into their business model. A DSS is a “highly flexible and interactive IT system that is designed to support decision making when the problem is not structured.” (Haag, Cummins p.162) Managers require information to guide their organization in the right direction. DSS increases productivity, efficiency, and enhances understanding of business processes. DSS helped carve their business success, facilitate management making qualitative decisions, and turned their raw data into valued information that was needed by employees and management. DSS assist the management and employees of Frito-Lay by delivering statistical and data retrieving systems. Employees of Frito-Lay also used DSS systems in searching information that was germane to their job function. The three main components of a DSS are model management, data management and interface management. “The model requests the information from the data management component, analyzes the information, and sends the results to the user interface management component, which in turn passes the results back,” (Haag, Cummins p.163) to the user. There are many types of DSS systems and hybrid DSS systems...

...Moriarty Technologies have developed a Decision Support System to analyse Steam Age Emporiums sales data and different business options in order to determine the best case scenario for the business. It was established that the best business strategy for your company would be to adopt Store Recommended Mark-up as your pricing method, Monsieur Bonacieux Transport as your freight solution and Brunei as your country of import. Additionally, recommendations for the business to offer discounts, free freight delivery and to monitor fluctuations in exchange rates have been made. A Decision Support System (DSS) is an information system built to support the phases of a users decision making process (Mora, Forgionne & Gupta 2003, p. preface). It provides assistance in manipulating and evaluating large amounts of detailed data to choose from many different courses of action (Baltzan, Lynch & Blakey 2013). These features make it the appropriate tool for this project as over 1000 rows and 29 columns of data needed to be manipulated and analysed to create 8 different scenarios to allow the best decision to be made. The DDS was utilised to analyse sales data to determine that the Store Mark-up type would be the most beneficial option for the business. Analysis of the ‘Selling Price’ column of the Report was conducted to ensure that other factors such as discounts would not affect the outcomes. The DDS determined that the Store Recommended Mark-up would generate $169 559.42 versus...

...Computerized Decision Support System Computerizing health care is said to be an effective method not only transforming the quality of health care, but also reducing the cost as well. Electronic health records have been implemented in healthcare facilities throughout the nation to enhance their outcomes. Electronic health records can enhance healthcare with a variety of means collectively known as computerized decision support system (CDSS). The purpose of a CDSS is to deliver patient-specific information centered on substantial knowledge. Implementing a CDSS is expected to depress numerous challenges in healthcare. Challenges such as treatment blunders and high costs will no longer be an issue for concern. The CDSS may function as an instrument to aid clinicians in management as well as a memory aid. The CDSS is an information technology that assists healthcare professionals with the medical process to improve the patients’ health and the quality of the healthcare system. By providing patient data, medical content, clinical recommendations, and explanations, physicians can effectively treat his or her patients in a timely fashion. Initially physicians would merely input information about the patient into his or her data system, and the CDSS would present him or her with the diagnosis solution for the patient. At that point, the physician would take the appropriate steps to act on the output that the CDSS provided them with. Today physicians work together with the CDSS to produce...

...Identify a problem within an area of Management responsibility and create a Decision Support System to solve it. INTRODUCTION Managers are often faced with problems that may affect the flow of work. It is crucial that managers find the most suitable way of solving the problems they encounter. Some of the many problems encountered involve decision making, and managers need to come up with the most effective system in order to make decisions in a quick and effortless manner. The decision support system is one such system. According to Laudon et al (2006), decision support systems are “information systems at the organization’s management level that combine data and sophisticated analytical models or data analysis tools to support semi-structured and unstructured decision making”. (p. 462) STATEMENT OF PROBLEM The Entertainers Credit Union Limited has been in existence for twenty years. Its main revenue building products are loans. At present, however, management has noticed a significant downturn in revenues linked directly to a persistent reduction of loans inflow as well as a decline in applications for membership. The marketing team was tasked with the responsibility of researching the source of this worrying trend, and it was discovered that one of the most significant grouses maintained by most members was that the length of time between signing of the Loan Application and getting meaningful feedback on whether their loans were approved or not, took an unbearably...

... Exercise 1 What is a Decision Support System? A decision support system is a processor information technique that assists with the company’s managerial endeavors. Decision support systems operate administration, business procedures, and product development of a company and assist to formulate conclusions, within a changing environment. Some of the responsibilities of a decision support system include the following: planning and organizing organization activities, provide data, conduct training programs, evaluate computer products, and provide support. Organizations depend on decision support systems to assist them with answering all business related questions and concerns. Decision support systems rely heavily on information, as the operations management technique uses the information to evaluate and examine. The Problem According to Watson and Carr (1987), “There are a number of organization structure alternatives for supporting decision support systems, and each alternative has its advantages and disadvantages” (p.84). Each organization has to be able to support the efforts of the decision support system, which consist of assisting clients to assess the computer products, supply access to information, and partake in product development. The issue of the “Organizing for Decision Support System Support: The End-User Services Alternative” article argues which division within a company is responsible for the decision support system. This determination has a considerable...

...CURRENT ISSUES OF DECISION SUPPORT SYSTEM Cynthia P. C. Lee Abstract This paper emphasized on the Decision Support System (DSS) defined in various ways depending upon the author’s point of view by Turban (1995), Little (1970), Moore and Chang (1980), Keen (1980), and Power (1997); history of DSS during late 1950s and early 1960s until millennium approached of Web-based analytical applications; the Decision support system (DSS) has been used in many different ways (Alter 1980, Power, 2002). Turban (1995) defines it as "an interactive, flexible, and adaptable computerbased information system, especially developed for supporting the solution of a nonstructured management problem for improved decision making. It utilizes data, provides an easy-to-use interface, and allows for the decision maker's own insights." For Little (1970), a DSS is a "model-based set of procedures for processing data and judgments to assist a manager in his decision-making." Moore and Chang (1980) define DSS as extendible systems capable of supporting ad hoc data analysis and decision modeling, oriented toward future planning, and used at irregular, unplanned intervals. importance of DSS to assist in high-level decision-making, assist academic advising staff, improve the quality and timeliness of marketing decisions, and medical diagnosis process; and current issues of DSS where decision-making as the most important activities for human beings, Clinical Decision Support Systems (CDSSs), several...
