Conventional Decision Support
          System (DSS)
• Current DSS facilitate a wide variety of decision
  tasks:
           Information Gathering and Analysis

                         Model Building

                      Sensitivity Analysis

                   Alternative Evaluation

                  Decision Implementation



             Jasour A.Obeidat – Middle East University, Jan.2013
Why Internet & World Wide Web?

• The global internet is now enabling technologies
  for delivering computerized decision support
  systems.

• There are many on-going efforts to develop and
  implement Web-Based DSS in various areas such
  as:
    Health Care.
    Private Companies.
    Governments.
    Education.


             Jasour A.Obeidat – Middle East University, Jan.2013
Web-based Decision Support
            System
• Delivering decision support information or tool to
  manager or business analyst.

• The computer that is hosting DSS application is
  linked to user’s computer via computer networks
  with TCP/IP.
Web-based Decision Support
            System
• Main Terms:

   Web-Based
    The entire application is implemented using web
    technologies.



   Web-Enabled
    key part of an application like a database remain on a
    legacy system, but the application can be accessed from
    a web-based component and displayed in a browser.



             Jasour A.Obeidat – Middle East University, Jan.2013
Web-based Decision Support
            System
• Approaches used to deliver Web-Based DSS:

    Data Driven Approach
     Which helps managers to {Organize, Retrieve, Analysis}
     large volume of relevant data using database and OLAP
     techniques.

    Model Driven Approach
     Formal representations of decision model and provide
     analytical support using the tools of decisions such as:
   - Decision Analysis.
   - Decision Simulation.
   - Decision Statistics.
              Jasour A.Obeidat – Middle East University, Jan.2013
Decision Technology As A Service

• Web technologies can be classified as:



        Facilitate platform
    independent and universal                        Allow more capabilities to
    access to decision support                       be embedded in the user
            application                                     interface


      Relevant Technologies                            Relevant Technologies

Recent Research in Web-based
              DSS
• Researches in this area concentrate on two point
  of views:




            Jasour A.Obeidat – Middle East University, Jan.2013
Recent Research in Web-based DSS-
  Architecture & Technologies (1)

  Idea & Concentration
DSS meta data model for distributing decision support
system on the web.


      EXPLANATION
 The ability to find appropriate resources on the web and
determine their situation ability.

 Meta data helps end users to locate and understand a
specific DSS capability on the web.



             Jasour A.Obeidat – Middle East University, Jan.2013
Recent Research in Web-based DSS-
      Architecture & Technologies (2)
.     Idea & Concentration
    Investigate customers satisfaction with web-based decision
    support system

          EXPLANATION
     Proposing three independent variables:
        -System Quality {Ease of use, convenience of access}.
        - Information     Quality     {Relevance,   Accuracy,
        Completeness, Timeliness}.
        -Information Presentation.
     As a results: System quality and information quality are
    correlated to end users satisfaction.
     Information representation : did not have a statistically
    significant impact on an end users.

Recent Research in Web-based DSS-
     Application and Implementation(1)
.
           Application
    Web Based DSS for Hospital Management.


         Implementation


    It is a customer relationship management system for
    physician relationship management , called physician
    profiling system




               Jasour A.Obeidat – Middle East University, Jan.2013
Recent Research in Web-based DSS-
     Application and Implementation(2)
.
            Application
    Web-based DSS that used a model based on fuzzy set
    theory to perform risk analysis for e-commerce
    development


          Implementation
     In Prototype:
      - Web browser : Used as Interface component.
      - Database / DSS Models : Hosted at Servers.
     Prototype Usage:
      - Helps managers to { identify , Analyze , Prioritize} risks.

Recent Research in Web-based DSS-
     Application and Implementation(3)
.          Application
    Web-based DSS framework for portfolio selection.

         Implementation
     Uses Online Analytical Processing OLAP and Parallel
    Virtual Machine PVM.
     In Prototype:
    -Enables multiple computers to handle a large-scale
    decision support problems .
     Performance: IMPROVED !!!
    - By using multiple user interfaces (i.e. Web browser)
    accessing database hosted over servers and analyzed
    based on DSS models hosted too.
                Jasour A.Obeidat – Middle East University, Jan.2013
Benefits of Web-based DSS


The benefits of building web-based decision support
  system are :

      Increasing the availability.
      Growing sophistication of web technologies.
      Providing remote controlling.
      Distributed computations.
      Exchange of complex multimedia information.
Challenges faces Web-based DSS

 Technological Challenges :
 The basic web architectural model designed for random
  jumps in hyperspace, without providing a persistent
  connection or state. But DSS generally needs repeated
  interactions with a model and exchange a large amount
  of data speared across interactions.

 Economical Challenges:
  To offer decision support as a service, providers must
  experiment the new payments methods.

 Social and behavioral challenge:
  The type of users by applying Web-based DSS casual
  users , where , the previous users were professionals.
