On advancing modelling methodology

"Variable structure systems have been introduced as a new system class by Oeren [Oer75]." (p.8).

"T.I. Ören introduces a new paradigm of modelling. A Simulation model can be automatically tailored as a piecewise continuous system with a set of discontinuities representing changes in parameters, dynamics etc." (p. 48).

"A new paradigm, structural simulation (as opposed to conventional 'trajectory' simulation) is needed to avoid having to force structural changes down to the same level as behavioral ones (Ören 1975; Zeigler 1976; Davis 1986; Hogeweg and Hesper1986; Elbert and Salter, 1986; Sampson, 1984.)"

"Advances in simulation environments toward support of hierarchical, modular model construction are typified by MAGEST (Oren, 1983; Aytac and Oren, this volume) and BORIS (Decker, 1980)." (p. 195). ... "In an early paper (Oren, 1975), and more recently in a taxonomy of models (Oren , 1979, 1985), Tuncer Oren introduced the term "variable structure model" in the sense in which we shall use it here."

"In the 1970s a series of more systematic and profound studies aimed at providing a theoretical foundation for modelling. Three names are strongly associated with this theoretical foundation for simulation modelling: Bernard P. Zeigler, Tuncer I. Ören and Maurice S. Elzas. Their series of books (Zeigler, 1976, 1984, Zeigler et al. 1979, Ören, 1978, Ören et al, 1984, Elzas et al., 1986, 1989) was the stage for publication of novel views by many authors whose contributions to the modelling process and its technology are still very relevant today. ... Next to the ‘godfathers’ of modelling and simulation, some of these authors inspired me and have to be mentioned here ..."
