The Ethics of Computer Simulations: Challenges and Perspectives for the Future of Science and Technology

Juan M. Durán
University of Stuttgart

Brief Bio
Juan M. Durán studied computer science (1998-2003) and philosophy (2003-2008) in Argentina. Before moving to Germany for his PhD (2009-2013), he had worked for the National Aerospace Agency, taught at the University, and worked in private business. His PhD was carried out within the German Excellence Initiative Graduate School Simulation Technology, where he wrote his dissertation on the epistemology and methodology of computer simulations. After these studies, he returned to Argentina with a postdoc position granted by the National Scientific and Technical Research Council for a project on scientific explanation for computer simulations (2014-2016). After two years of research and teaching, he returned to Germany as a Research Associate at the High-Performance Computing Center Stuttgart, at the University of Stuttgart (2016-2018). His work focuses on the philosophy of computer simulations broadly conceived, from the methodology and epistemology, to his more recent work on ethics and the place of computer simulations in knowledge society.

Computer simulations represent, without a doubt, a scientific novelty in contemporary research. But in what sense do they also raise philosophical concerns? Although there are a number of issues that philosophers have pointed out as central to the analysis of computer simulations, admittedly many revolve around philosophical debates with little interests for researchers working with computer simulations. The question that we should be asking, then, is what sort of issues of a philosophical nature are tailored to computer simulations and attract the interest of practitioners? A good way to approach to this question is by addressing the ethics of computer simulations. Surprisingly, there is very little discussion on this matter. Nevertheless, three viewpoints can be identified. First, it is claimed that computer simulations raise ethical concerns in cases where their results are not reliable. Second, computer simulations raise ethical concerns when they are biased (for instance, in their representations). Finally, it is claimed that computer simulations raise ethical concerns if the researchers do not behave professionally. Each viewpoint emphasises a different and relevant aspect of computer simulations. But unfortunately more needs to be said. This talk will examine all three approaches to the ethics of computer simulations and ask, furthermore, whether there are more ethical issues that are currently going under the radar of philosophers (and thus requires the aid of professional practitioners).

Artificial intelligence is one of much talked about topics these days, and it is considered to be a crucial factor for an effective and efficient solution of many key problems facing the technology, economy and society. This hope is amplified by its remarkable ability to make use of large data sets that are omnipresent and, when analyzed and processed properly, can make it possible to obtain and codify much knowledge about what is done, or should be done, in a variety of situations. This remarkable ability of broadly perceived artificial intelligence based approaches is amplified by an universally accepted requirement they have to satify, namely to provide transparency, comprehensibility, etc. of the reasons behind and processes employed to find a solution, to just mention a few.Yet, in spite of that remarkable progress in all kinds of artificial intelligence tools and techniques, there are still many situations when a fully automated analysis and derivation of decisions is not the best solution. It may be often more expedient to explicitly include the human being in the process, notably when sophisticated problems are considered, human judgments are to be taken into account with all their subtle semantics, etc.. There are numerous examples in both, to just quote a few examples, economic planning, automation and robotics, traffic control, etc. This all calls for new computing paradigms that can be termed as human centric, in general, human-in-the-loop, in a more specific context, with many other cases.


First, we briefly present the essence of some new computing paradigms that try to attain a synergy, and bridge the gap between the human user and computer systems, notably the so-called: human centric computing, human centered computing, human computing, etc. Then, we will discuss in more detail some approaches to the so-called human-in-the-loop, on some examples of planning and intelligent robotics. We will consider them in the context of systems modeling and decision making. We present a brief account of modern approaches to real world decision making, emphasize the concept of a decision making process that involves more factors and aspects like: the use of explicit and tacit knowledge, intuition, individual habitual domains, non-trivial rationality, different paradigms, etc. We advocate the need for computer based decision support systems. After a short presentation of their history and classification, we indicate that decision support systems should incorporate some sort of “intelligence”, and we first briefly mention some views of intelligence in an individual and collective perspective. We also mention the role of modeling and simulation for solving complex problems. We indicate possible advantages of using those new human-centered computing paradigms in the decision making and support context, and advocate the use of human consistent forms of presentation of data and results, and decision suggestions. We will concentrate on the use of some novel tools of verbalization, notably the use of linguistic summaries of large sets of data. Finally, we show an example of our own implementation of a data/document driven decision support system for a computer retailer in which linguistic database summaries, elements of business intelligence and Web intelligence are combined.

Recent advances in computer technology have influenced simulation techniques to become an effective approach to understand physical systems. In recent years, grid-shaped cellular models have gained popularity in this sense. In particular, Cellular Automata (CA) have been widely used with these purposes. Despite their usefulness to describe complex behavior, CA can require large amounts of compute time, mainly due to its synchronous nature. The use of a discrete time base also constrains the precision of the model. Besides this, CA do not describe adequately most of existing physical systems whose nature is asynchronous. The Cell-DEVS formalism was defined in order to attack these problems. The goal of Cell-DEVS is to build discrete-event cell spaces, improving their definition by making the timing specification more expressive.
We will introduce the main characteristics of the Cell-DEVS formalism, and will show how to model complex cell spaces in. We will present different examples of application, and discuss open research issues in this area. We will then focus on advanced models of pedestrian flow and crowds. The methodology uses a cellular modeling approach in which each cell is defined as a discrete event agent, and defines a procedure to couple cells evolving the state of the influenced neighbors.
