...2000). With Internet-hosted databases and user friendly query device being mostly used, organizations are turning to decision support systems (DSS) software to analyze the company's databases and develop them into information helpful for decision makers. According to Power (2007) information Systems researchers and technologists have built and investigated computerized Decision Support Systems (DSS) for approximately 40 years. For the purpose of this work, I will define DSS as computer software that facilitates and accepts inputs of a large number of facts and methods to convert them into meaningful comparisons, graphs, and trends that can facilitate and enhance decision makers’ decision-making abilities to solve problems (Haitham, 2015). The advantages of using decision support systems for decision making. The use of DSS has been positively associated with success of better decisions that enhanced employees’ productivity (Edwards et al., 2000; Haag & Cummings, 2008).In my team, we have lots of reports to submit as required by OSHA /EPA and DSS software is being used to achieve 76 percent time reduction in information and report generating and a 40 percent rise in user productivity. DSS typically includes analytical and report-writing features, thus enabling users to translate raw data into a form useful for decision support. DSS, which offers users more flexible programming paradigms, can be compared to another type of software, which enhances productivity by accelerating...

...then response to the changing market condition and customer needs. A more defined organizational structure, performance metrics and decision support systems (DSS) in SCM is required to create competitive advantages for an organization. Since Information Technology/Information System (IT/IS) is an integral component of SCM, DSS is inevitable in making available the right information at the right time so that managers can make timely and more accurate decisions. However, there is no best known DSS type that is required to effectively manage a supply chain. A properly designed DSS will help decision makers to extract useful information from raw data, documents, personal knowledge and/or business models with the objective of identifying and solving problems, and making decisions. Decision Support Systems (DSS) are a specific class of computerized information system that supports business and organizational decision-making activities. The DSS in supply chain management can be a model, communication, data, document and knowledge driven. Three fundamental components of DSS architecture are: (i) Input data: database or knowledge base, (ii) Analytical Tool: the model (decision context and user criteria) and (iii) use interface, should be given due consideration while developing supply chain decision support systems (Figure1: DSS Components). B. Introduction The Objective of this paper is to define the importance of decision support systems in Supply Chain...

...TOPic: DECISION SUPPORT SYSTEMS: AN OVERVIEW AND ITS ROLE IN BUSINESS Introduction A decision support system (DSS) is a computer-based information system that supports business or organizational decision-making activities. DSSs serve the management, operations, and planning levels of an organization and help to make decisions, which may be rapidly changing and not easily specified in advance. Typical information that a decision support application might gather and present are: * 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. Making decisions concerning complex systems (e.g., the management of organizational operations, industrial processes, or investment portfolios; the command and control of military units; or the control of nuclear power plants) often strains our cognitive capabilities. Even though individual interactions among a system's variables may be well understood, predicting how the system will react to an external manipulation such as a policy decision is often difficult. What will be, for example, the effect of introducing the third shift on a factory floor? One might expect that this will increase the plant's output by roughly 50 percent. Factors such as additional wages, machine weardown, maintenance breaks, raw material usage, supply logistics, and...

...AN INTRODUCTION TO PCI-DSS COMPLIANCE Author: Nicholas Henry April 2016 Table of Contents 1. Abstract 2. History 3. PCI-DSS Overview 4. Understanding PCI-DSS Compliance 5. Achieving PCI-DSS Compliance 6. PCI-DSS in the IT Department 7. Negatives of PCI-DSS 8. Positives of PCI-DSS Abstract Around the world, consumer migration from traditional cash and check payments to electronic payment methods such as credit, debit or bank transfers continue to grow. In 2009 a survey discovered that less than 37% of all payments are now made using cash or check. While there are many benefits to this, there are also significant new issues introduced as a result. As customers use electronic payment methods, there is an expectation of security for the cardholder’s identity and payment information. With all the recent data theft and security breaches, this is becoming a significant issue. To ensure the protection of consumer information, the Payment Card Industry, or PCI, developed a set of data security standards (DSS) that merchants and financial service providers must maintain to be able to process debit and credit cards. While PCI does not manage compliance or impose consequences for non-compliance, individual card associations may initiate financial/operational penalties to businesses that are non-compliant...

...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...

...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 types of DSS usage and deployment, and Social decision support system...

...Australia. Tel: þ 618-92667390; Fax: þ 618-92663076; E-mail: pervang@cbs.curtin.edu.au Abstract This paper critically analyses the nature and state of decision support systems (DSS) research. To provide context for the analysis, a history of DSS is presented which focuses on the evolution of a number of sub-groupings of research and practice: personal DSS, group support systems, negotiation support systems, intelligent DSS, knowledge management-based DSS, executive information systems/business intelligence, and data warehousing. To understand the state of DSS research an empirical investigation of published DSS research is presented. This investigation is based on the detailed analysis of 1,020 DSS articles published in 14 major journals from 1990 to 2003. The analysis found that DSS publication has been falling steadily since its peak in 1994 and the current publication rate is at early 1990s levels. Other findings include that personal DSS and group support systems dominate research activity and data warehousing is the least published type of DSS. The journal DSS is the major publishing outlet; US ‘Other’ journals dominate DSS publishing and there is very low exposure of DSS in European journals. Around two-thirds of DSS research is empirical, a much higher proportion than general IS research. DSS empirical research is overwhelming positivist, and is more dominated by positivism than IS research in general. Design science is a major...

...of the Current State of Technology With the increasing demand for up- to- date, correct and relevant information in the business world, it is crucial for each business to take advantage of breakthroughs in information technology specifically in the field of information systems. Information generated is used by decision makers to gain competitive advantage against competitors and to take advantage of opportunities to increase business performance, effectiveness and efficiency. One of the several information systems which are considered to be of the great help for managers in decision making is the decision support system. Decision Support System (DSS) combines models and data in an attempt to solve semi- structured and some unstructured problems with extensive user involvement. With correct gathering and manipulation of data, DSS can provide several alternative solutions which in turn can lead to correct decision making. Today, there are many companies adopting decision – support systems and data mining software not only in the U.S. but also in the Philippines. However, there is limited literature on companies in Iloilo City adopting this technology. For this reason, the proponents saw the need to study the process of one company in Iloilo City where this type of information system can be adopted. That company is Westvis Marketing Corporation. Westvis Marketing Corporation (WMC) was founded by Mr. Honesto Tomas Hsia on April 2011. Mr. Hsia was a former managing partner in...

...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. Four DSS systems that could be implemented in a business are communication driven, knowledge driven , data driven , and document driven . Hybrid DSS systems are computerized systems that take advantage of combined DSS systems. A DSS may present information graphically and may include...
