There are many definitions of system. One dictionary definition calls it “a group or combination of interrelated, independent or interacting elements forming a collective entity”. A system is an assembly of components or elements having a functional relationship to achieve a common objective for a useful purpose. A system is composed of components, attributes, and relationships. These are described as follows: Components are the operating parts of the system consisting of input, process, and output. Each system component may assume a variety of values to describe a system state, as set by some control action and one or more restrictions.Attributes are the properties or discernible manifestations of the components of a system. These attributes characterize the system.Relationships are the links between components and attributes.

In order to create and display Web pages, some type of markup language is necessary. While there are many types of markup languages, we will briefly introduce three common types here: Hypertext Markup Language (HTML), dynamic Hypertext Markup Language (dynamic HTML), and Extensible Markup Language (XML). HTML, D-HTML, and XML are members of a family of markup languages called Standard Generalized Markup Language (SGML). Despite the name, SGML itself is not a markup language but a description of how to create a markup language. To put it another way, SGML is a metalanguage. HTML is a set of codes inserted into a document that is intended for display on a Web browser. The codes, or markup symbols, instruct the browser how to display a Web page’s text, images, and other elements. The individual markup codes are often referred to as tags and are surrounded by brackets (< >). Most HTML tags consist of an opening tag, followed by one or more attributes, and a closing tag. Closing tags are preceded by a forward slash (/). Attributes are parameters that specify various qualities that an HTML tag can take on. For example, a common attribute is HREF, which specifies the URL of a file in an anchor tag (<A>).

Systems Engineering is a process whereby engineers analyse and optimize the whole technical system, which is composed of components, attributes and relationships, to achieve a specified goal. Components, attributes and relationships, in an engineering sense, are defined as follows: Components are the operating parts of a system (see Figure 2.4), consisting of input, process and output. Each system component may assume a variety of values to describe a system state set by control actions and restrictions.Attributes are the properties or discernible manifestations of the components of a system. These attributes characterize the system.Relationships are the links between components and attributes.

In discrete event simulation, attributes, variables, and event notices serve as the input to a model, with the performance measures as the corresponding output [20]. Attributes and variables collectively describe the properties of an entity (e.g. machine, product, or buffer) in a model. The difference is that attributes take on a fixed value in a model, whereas variables take on values that can be varied during each model run. The resource parameters and the variables defined previously translates into the attributes and variables, respectively, while event notices provide a record of event occurrences along with the necessary data to execute the events. A model represents an abstraction of a manufacturing environment containing structural, logical, or mathematical relationships that, with the attributes, variables, and event notices (collectively known as a system), describe the state of a model at any time. A performance measure displays an evaluated aspect of the system’s performance.
