** Request for Conference Proposals - PSE 2012 ** The PSE Executive Committee is currently requesting conference proposals from potential Asian sponsors of PSE '2012. The purpose of these series of meetings is to bring together researchers and practitioners involved in the creation and application of computational-based methodologies for planning, design, operation, control and maintenance of chemical processes. The meetings are international by design, with representation from Asia and the Pacific, Europe and Africa, and the Americas. The conference, organized by the Executive Committee of the Process Systems Engineering Symposium Series, draws its representation from the Asian Pacific Confederation of Chemical Engineering, the European Federation of Chemical Engineering, and the Inter-American Confederation of Chemical Engineering. Previous conferences were held in Garmisch-Partenkirchen, Germany (2006), Kunming, P.R.China (2003), Colorado, USA (2000), Trondheim, Norway (1997), Kyongju, Korea (1994), Montebello, Canada (1991), Sydney, Australia (1988), Cambridge, England (1985), and Kyoto, Japan (1982). PSE '09 meeting will take place in Salvador, Brazil from August,16 to 20, 2009. For PSE '2012, the conference will move back to an Asian venue (including the Pacific and Australia) and we look forward to continuing the high quality of meetings as in the past. While there is no fixed format to conference proposals, the PSE Executive Committee needs to consider the following factors in a successful bid: - important conference themes for PSE - conference format and mix of invited/contributed presentations - funding sources and suggested conference fees - unique characteristics of the proposed program, venue and facility Conference proposals are welcomed until December 31, 2008. Received proposals will be considered early in 2009, and proposers of the winning PSE '2012 bid will be contacted before the PSE '2009 meeting. G. V. Reklaitis, R. Gani, L. T. Biegler
