Center for Research on The Application of Mathematics (P2MS) was created to promote the roles of mathematics in modeling and simulation in 1994. In the past few years, P2MS has consistently shown its direction towards an applied profile by carefully moving into a multi-disciplinary center. The task to create the linkages among scientists, engineers, and industry practitioners requires solid group in which P2MS is currently, actively building this group involving local and international scientists. A major breakthrough has been indicated from the success of P2MS in coordinating a Research Consortium: OPPINET (Optimization on Gas and Oil Pipeline Network) sponsored by major Indonesian Oil and Gas Companies since 2001. Collaborations with a number of institutions, national as well as international, have been built and constantly developed.
