DSS ? an interactive computer-based system or subsystem intended to help decision makers use communications technologies, data, documents, knowledge and/or models to identify and solve problems, complete decision process tasks, and make decision interactive computer-based system
DSS ? general term for any computer application that enhances a person or group’s ability to make decisions. enhances a person or group’s ability to make decisions.
DSS ? a computer-based system that represents and processes knowledge in ways that allow decision making to be more productive, agile, innovative, and/or reputable productive, agile, innovative, and/or reputable
DSS ? academic field of research that involves designing and studying Decision Support Systems in their context of use.
Before we continue…. DSS should be : interactive computer-based system enhances a person or group’s ability to make decisions More productive, agile, innovative, and/or reputable
DSS for IS Increasing complexity of decisions Technology Information: “Data, data everywhere, and not the time to think!” Number and complexity of options Pace of change Increasing availability of computerized support Inexpensive high-powered computing Better software More efficient software development process Increasing usability of computers
Let’s get realistic…. For your final project ? Fearness : Is it all about algorithm ? Is it hard to do ? Am I capable to do this ? Confusion : I don’t have the problem I am very weak at math Programming must be difficult
Let’s get realistic…. IS + DSS = Value added IS IS + DSS = easy to do IS + DSS = should be easy to represent IS + DSS = should be fast if you already have the IS IS + DSS = should be easier because you have focus in it
Before we continue… This course : should not teach many algorithms Should just teach the concept and introductory Should be resulting good project for your final project proposal Should become the door to open your mind before you graduate
Decision ? Decision: a reasoned choice among alternatives Examples: Where to advertise a new product What stock to buy What movie to see Where to go for dinner Decision Making: a process of choosing among alternative courses of action for the purpose of attaining a goal or goals
Type of Decision Unstructured Structured Semi-Structured
Before we continue….. So, is MIS course has already being forgotten ? Do you really think management science is non-sense ? Do you already think that expert system and artificial intelligence is nothing ? Have you already have final project proposal ?
Types of DSS uses storage and processing technologies to document retrieval and analysis. It manages, retrieves and manipulates unstructured information in a variety of electronic formats provides specialized problem solving expertise stored as facts, rules, procedures, or in similar structures. It suggest or recommend actions to managers. emphasizes access to and manipulation of a statistical, financial, optimization, or simulation model. Model-driven DSS use data and parameters provided by users to assist decision makers in analyzing a situation; they are not necessarily data intensive use network and communication technologies to facilitate collaboartion on decision making. It supports more than one person working on a shared task emphasizes access to and manipulation of a time series of internal company data and, sometimes, external data.
