Cynthia P. C. Lee

Abstract

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 (SDSS) .

In contrast, Keen (1980) claims that it is impossible to all give the a precise of definition the DSS.

...Introduction 1.1 Company Background Akademi Teknikal Laut Malaysia (ATLAM) was establish on 15 August 1991 but then subsequently privatized on 1st January 1997. It is located in Melaka and Terengganu. ATLAM’s vision is to be a leader in maritime education and training, while its mission is to facilitate value added learning via a conducive environment and offer services to its clients. ATLAM revamped its Information Technology (IT) facilities in 2000. Before 2001, ATLAM relied on a customized single-user system bought from a vendor. The desktop computers (PCs) were only used to enter accounting entry but had not been functioned to produce financial report. Consequently, ATLAM needed to look for alternative to upgrade its accounting system. On December 2001, the management of ATLAM had been asking to upgrade its accounting system with the PETRA group-wide Systems, Applications and Products (SAP) system. It is an incorporated business applications package that covered most function of an organization. There are some factors to look into the company especially on IT infrastructure, accounting system and acceptance the new system for ATLAM staff. Mr. Zulkifli Osman, as the Finance Manager since 1995, had to critically assess the risks associated with the decision of whether changing to SAP system suggested by PETRA Group or ACCPAC System suggested by Mr. Lim (User Representative).

...Case study: When radiation therapy kills When new expensive medical therapies come along, promising to cure people of illness, one would think that the manufacturers, doctors,and technicians, along with the hospitals and state oversight agencies, would take extreme caution in their application and use. Often this is not the case. Contemporary radiation therapy offers a good example of society failing to anticipate and control the negative impacts of a technology powerful enough to kill people. For individuals and their families suffering through a battle with cancer, technical advancements in radiation treatment represent hope and a chance for a healthy, cancer-free life. But when these highly complex machines used to treat cancers go awry or when nedical technicians and doctors fail to follow proper safety procedures, it results in suffering worse than ailments radication aims to cure. A litany of horror stories underscore the consequences when hospitals fail to provide safe radiation treatment to cancer patients. In many of these horror stories, poor software design, poor human-machine interfaces and lack of proper training are root causes of the problems. The deaths of Scott Jerome-Parks and Alexandra Jn-Charles, both patients of New york City hospitals, are prime examples of radiation treatments going awry. Jerome-Parks worked in southern Manhattan near the side of the World Trade Center attacks, and suspected that the tongue cancer he developed later was related to...

Then make recommendations as to what the Canadian should do choosing from the list below, ranking them in order of priority, adding any other actions you think necessary. Dave Thompson is a Canadian working for a ‘Baby Bell’ company which owns shares in a Taiwanese mobile phone company. They have recently acquired a license to operate in this crowded and competitive market. Dave has been posted to Taiwan on a three-year contract. He now has been living there for three months. He has good experience of the mobile phone business, both technically and strategically, and was previously involved in the start-up of a new mobile company in Lithuania. He believes he has the opportunity to make the new company a great success by adopting the management style of his home company: open, innovative, confident and aggressive. In Taiwan he faces a tradition based on Chinese hierarchies and family-run businesses. The Taiwanese company Dave works for belongs to one of these families, but the current generation sees the advantages of a western approach in what is for them a new kind of business. So they back his efforts to ‘turn the company around’. Dave’s biggest problem is one of time: he wants to get on with building up a western-style...

...Electrochemistry Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (the electrode: a metal or a semiconductor) and an ionic conductor (the electrolyte). These reactions involve electron transfer between the electrode and the electrolyte or species in solution. If a chemical reaction is driven by an externally applied voltage, as in electrolysis, or if a voltage is created by a chemical reaction as in a battery, it is an electrochemical reaction. In contrast, chemical reactions where electrons are transferred between molecules are called oxidation-reduction (redox) reactions. In general, electrochemistry deals with situations where redox reactions are separated in space or time, connected by an external electric circuit. Principles Oxidation and reduction The term "redox" stands for reduction-oxidation. It refers to electrochemical processes involving electron transfer to or from a molecule or ion changing its oxidation state. This reaction can occur through the application of an external voltage or through the release of chemical energy. Oxidation and reduction describe the change of oxidation state that takes place in the atoms, ions or molecules involved in an electrochemical reaction. Formally, oxidation state is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic. An atom or ion that gives up an electron to another atom or...

Unusual behaviour - Jamel’s body language Unusual behaviour is seen through an individual's recognizable behaviour pattern to attempt to cope with the stress. The guilty leads to fear; fear leads to stress; and stress leads to behaviour changes. Research in psychology reveals that when a person, especially a first-time offender, commits a crime, he or she becomes engulfed by emotions of fear and guilt. Those emotions cause the individual to experience a significant amount of stress, and in order to cope with the stress, the individual will exhibit unusual and recognizable behaviour patterns. In this case, Jamel’s behaviour is very suspicious. First, body language such as the facial expressions and body posture can show people emotion and thinking especially...

...Case Study: Snyder's of Hanover: New Systems for an Old Family Company Harry V. Warehime began tempting the taste buds of southern Pennsylvanians with his Hanover Olde Tyme Pretzels in 1909. Since then, Snyder's of Hanover, as the company came to be known, has expanded its business beyond any scope that its founder might have dared to imagine. Snyder's of Hanover remains a family-owned and family-run company, but it has become the world's second largest pretzel maker, with 12.1 percent of the pretzel market. Snyder's pretzel and chip varieties include Old Tyme Pretzels, Jalapeno Pieces, Butter Snaps, and EatSmart All Natural Veggie Crisps, as well as other popular snacks. In 2002, Snyder's posted revenues of $164 million, trailing only Rold Gold, the reigning champion of the pretzel industry. In addition to manufacturing its complete line of snack foods, Snyder's distributes its own products, as well as those of other snack food companies such as Tasty Baking Company's Tastykakes. With 40 distribution facilities all over the United States and Europe, over 4,500 products, and over 150 product lines, the home office in Hanover, Pennsylvania, has a considerable amount of data to manage. If there was one last vestige of old-fashioned business left at Snyder's, it was the company's method of managing and analyzing data. Although Snyder's sells more than 78 million bags of pretzels, chips, and organic snack items each year, some of its core systems were still heavily manual and paper-based...

...UNIX for DBA`s Author: Sandeep Akkasani 1. INTODUCTION TO UNIX 1.1 Single-User Systems The personal computer (PC) is a small General-purpose system that can execute programs to perform a wide variety of tasks. The PC, however, was designed for use by one person at a time, that is, it is Single-User oriented with MS-DOS as the de facto standard operating system for this range of machines. Single user systems became very popular due to the low cost hardware and wide range of software available for these machines. 1.2 Multi-User Systems As opposed to single-user systems there are also larger systems, which more than one person can use at any time. Such systems are referred to as multi-user systems. Multi-user systems would be required when a number of applications have to be run simultaneously, or common resources, like printers and disks, are to be shared by a number of users. 1.3 Hardware – Multi-User Systems While the hardware components of a multi-user system are similar to that of a singleuser system, the following differences should be noted. The CPU of a multi-user system is more powerful and has capabilities to support multi-programming and multi-tasking, two features essential for multi-user systems. The Hard disk of a multi-user system is bigger in capacity. Most multi-user systems use magnetic tape as external storage for backup of software.
