First, a brief summary of nonsequential solution concepts for this class of decision problems on multiprocessor systems will be given. The focus of attention will be put on coarse-grained parallelization and its implementation on multi-computer clusters. The conceptual design objectives for the OpTiX-II Software Environment will be presented as well as the implementation on a workstation cluster, a transputer system and a multiprocessor workstation (shared memory). The OpTiX-II system supports the steps from the formulation of decision problems to their solution on networks of (parallel) computers. In order to demonstrate the use of OpTiX-II, the solution of a decision problem from the field of structural design is discussed and some numerical test results are supplied. date: 1994-08 date_type: published publisher: WP-94-054 iiasapubid: WP-94-054 price: 10 creators_browse_id: 1738 creators_browse_id: 1921 full_text_status: public monograph_type: working_paper place_of_pub: IIASA, Laxenburg, Austria pages: 23 coversheets_dirty: FALSE fp7_type: info:eu-repo/semantics/book citation: Boden, H. & Grauer, M.
