Portrayal of reality has a vital role in simulation; since a portrayal of the real system should be utilised in the simulation (Grandy and Mills 2004). Thus, it is advantageous to examine reality/model dichotomy, which relies upon the reason for utilising/referring to the real world or reality (Luke, 1991). Regularly a portrayal of the truth is alluded to as a model (Edvardsson et al. 2008). In the event that when “reality” alludes to something to be built or something fictional, rather than reality, we may utilise the expression “system” or “system of interest” (Zyda, 2005). Some of the time model and reality may have surprising implications (Arva, 2008). We think about the real world/model dichotomy from an expansive point of view of, decision support, conception, illusion, pretence, imitation, perception and anticipation (Oliver and Radkowski 2014). 

In decision support, a substitute (a portrayal) of the reality is a “model“, which is utilised to experiment(s) under conditions that may even not be conceivable or achievable (Arva, 2008). Simulation is generally utilised for decision support (Edvardsson et al. 2008). 

Perception is significant, since the manner in which we see reality influences our emotions, choices, and actions (Oliver and Radkowski 2014). Perception predisposition is a halo effect, which is an exchange of generosity or constructive emotions around one characteristic, (for example, satisfying appearance) of an item or individual to another, conceivably random characteristics, (for example, performance) (Berendsen, 2001).

In conception, an image/picture or a portrayal of a current (real) or non-existing (fictional or to be engineered) entity is developed (Zyda, 2005). This is like perception; be that as it may, in perception, just a current reality is perceived (Choplin, 1996).

Anticipation is a fundamental characteristic for proactive decision making, as it is the situation in most astute systems (Choplin, 1996). In behaviourally anticipatory systems, the present image of the future (or current perception of the future) may influence current choices or decisions and subsequently may influence what’s to come in future (Crooltall et al. 1987).  

An “imitation” of an item is utilised as a substitute of that object (Klopfer and Squire 2007). A portion of the imitation objects are called fake, human-made, refined, counterfeit, and simulated; as it is the situation for “simulated leather”, for instance (Kingsepp, 2007). In this synthetic or human-made world, now and again the reality is adjusted, as it is the situation in genetically modified sustenances or foods (Kirkley and Kirkley 2005).

In everyday parlance as well as in technical terminology, copying or emulation has some similarity yet vary from imitation (Dede and Dunleavy 2014). In regular parlance, copying implies the imitation of behaviour; for instance, a kid may imitate his or her parents (Kingsepp, 2007). In fact, emulation implies that an object acts (for the most part by means of software) as if it is another item; along these lines by extension, copying is additionally utilised of an item (a system) rather than another (since behaviourally they are identical) (Luke, 1991). For instance, a PC can be utilised to imitate another (Klopfer and Squire 2007). Be that as it may, emulation is absolutely unique in relation to the simulation of a PC on another to perform tests utilising a model of the PC (Grandy and Mills 2004).

A illusion is a mistaken perception of reality (François, 1999). Now and again an illusion might be viewed as the reality (François, 2006). Charles Francois gave a superb example of this (Rondot, 1987). He said that what we see on a bright starry sky isn’t reality… yet a illusion; the light of some inaccessible stars (and galaxies) can’t be visible; since their light did not reach us yet; and a portion of the lights we see may have been emanated with tremendous time slips or lapse (François, 1999). Moreover, a portion of the stars (and cosmic systems) that we can see may have already ceased to exist (François, 2006).

At times, a representation (an image) of an element might be taken as though it is simply the substance (Wilmer, 2003). Belgian surrealist painter Rene ́ Magritte (1898–1967) delineated this by a painting of a pipe and titled it, in French “Ceci n’est pas une pipe” (This is not a pipe) (Lipinski, 1995). Indeed, what we see isn’t a pipe yet and a picture of a pipe (Page, 2017).

Pretence: According to Jean Baudrillard (1929– 2007) (French postmodernist) “something whatever imagined or pretended” gives an illusion of reality (Huyssen, 1989). In Simulation and Simulacra, Baudrillard utilises the ideas of the simulacrum (Ören, 2010). The duplicate without an original, and simulation, vital to a comprehension of the postmodern, to address the idea of mass reproduction and reproducibility that characterised our electronic media culture (Baudrillard, 2001). Furthermore, Baudrillard articulates the standard of a major rupture among modern day and postmodern social orders (Kellner, 2009). For Baudrillard, modern social orders are sorted out around the production and utilisation of commodities, while postmodern social orders are composed around simulation and the play of signs and images, signifying a circumstance where in codes, models, and signs are the arranging forms of another social order where simulation rules (Kellner, 2003). 

According to Jean Baudrillard, postmodern social orders are sorted out around “simulation” by which he implies the social methods of representation that “simulate” reality as in television, PC the internet, and virtual reality (Huyssen, 1989). Baudrillard has been a compelling figure in pointing this dichotomy of the reality and illusion of reality (Kellner, 2009). Within a universe of appearance, image and illusion, Baudrillard recommends, reality vanishes despite the fact that its traces keep on sustaining an illusion of the real (Baudrillard, 2001). A international journal is committed to Baudrillard contemplates and studies (Ören, 2009).

Jean Baudrillard claims that ‘the simulacrum is never that which conceals the truth it is the truth which conceals that there is none” in his book Simulacra and Simulation 1981 (Baudrillard, 2001). The phrase defines the idea of a new reality and simulation through a vintage lens (Huyssen, 1989). As Baudrillard overall point is that reality or rather a truth has ceased to exist and that everything has become a simulation of what was once the human race’s reality, which is why I wanted a vintage 1950s view of future to straighten this post-human race’s truth (Kellner, 2003). This idea itself is the base of the frame as the human and machine is the centre of the message (Ören, 2010). As the perception of future and human is an image of simulacrum as the robot hasn’t replaced the reality of man, but it is merely apart of reality (Kellner, 2009). The simulacrum hasn’t replaced reality, it is merely all that we are left with (Baudrillard, 2001).
