WSC 2067: What Are The Chances?
At the November 1967 “Conference on the Applications of Simulation Using GPSS” it seems unlikely that anyone was wondering if the conference would still be occupying a big hotel in 2017. Conferences persist for many reasons, but a technical conference like WSC has to remain relevant to users, vendors, researchers and consumers (not just hotels) to survive. If our kind of simulation vanished, then so (eventually) would WSC. What is required for simulation to “remain relevant” for the next 50 years? Without fear of having to answer for my crimes in 2067, I boldly speculate on what SHOULD matter for the next 10-20 years, if not the next 50, with a focus on our strength: dealing with uncertainty.

A Perspective on Fifty-Five Years of the Evolution of Scientific Respect for Simulation
This presentation will give a personal perspective on the evolution of how discrete-event simulation moved from having an image from the 1950s through the 1980s of being a “brute force programming effort” and as a problem solving “method of last resort” to today’s status where simulation enjoys “considerable scientific respect” as simulation is often the solution “method of choice” and has much “scholarly respect”. This evolution changed simulation from using “ad hoc methods” of solution on “early digital computers” to using simulation software systems containing “science-based methods” of solution on “modern day computers”.

Why Should We Develop Simulation Models in Pairs?
The conventional approach to model construction for simulation is to focus on a single model and follow a more or less structured development cycle. Why we put in twice the time and effort to develop two models rather than one? The answer lies in the fact that like most greedy heuristics, short-sightedness at the beginning may be much more costly in the end. This talk will champion the cause of the pairs-of-models (perhaps families of models) with discussion of multiresolution modeling. We show how the pair-of-models approach leads to be better results overall than construction of a complex model followed by a simpler model developed subsequently by necessity under stress when complexity overwhelms. Benefits include the ability to perform mutual cross-calibration, avoiding the usual difficulties in harmonization of the underlying ontologies as well as ability to better reconcile and correlate predictions of referent system outcomes.

Achievements and Lessons Learned from a Long-term Academic-Industrial Collaboration
I had the opportunity to work for about 14 years on many different projects with two manufacturing sites of the French-Italian semiconductor company STMicroelectronics. Supported by European, national and industrial projects, this still active long-term academic-industrial collaboration led to many scientific and industrial achievements, spreading to other companies. Through regular exchanges, engineers, researchers, PhD and Master students were able to present their problems, their advances and generate new research projects. After some history of the collaboration, the presentation will survey some of the main research and industrial results in qualification and flexibility management, production and capacity planning, scheduling, automated transportation, dynamic sampling and time constraint management. Challenges faced and lessons learned when applying Operations Research and Industrial Engineering in practice, and in particular in semiconductor manufacturing, will be discussed. Benefits for both practitioners and researchers will be emphasized, such as the opportunity to propose and study new relevant problems and develop and apply novel approaches using actual industrial data.

Military Simulation: A Ubiquitous Future
The Department of Defense uses Modeling and Simulation to support a variety of activities ranging from engineering to theater-level analytical studies, training, strategy evaluation and test. This talk presents some of the current challenges, research directions and promising opportunities to further exploit this powerful tool to understand complex system dynamics and predict performance.

History of Simulation in the United Kingdom
Discrete-event simulation first emerged in the late 1950s and steadily grew in popularity to become the most frequently used of the classical Operational Research techniques across a range of industries and users. The leading advances in the evolution of discrete-event simulation software came from the United Kingdom and the USA and this presenter was engaged for some 30 years with its development and use. The presentation reviews that history as a first-hand account, specifically in the United Kingdom.
