  2. The Positioning of Optimization Services Framework in OR/MS

  3. What is “Optimization Services” (OS)? • A proper noun. It’s intended as a standard, and it’s all new • A framework, NOT a system (cf. constitution, NOT government/Court System) • Only that the specifications are written in XML (NOT English) • Intended for next generation modeling systems as Internet resources. • Distributed Environment (cf. Local Environment is a Special Case, e.g. Monitor and CPU) • Decentralized Environment (Registry Vs. Server) • A Universal Idea (System Decomposition, Interfacing, Representation) • General Principle (4S) • Standard (oasis-open.org: discussion list -> technical committee -> draft -> Standard) • Simple (not the framework, but the framework components. Libraries provided) • Scalable (general OSxL specification design, where ‘x’ stands for any other 25 letters) • Smooth (Service Oriented Architecture or SOA, cf. Utility Services)

  4. System Components • Models and Instances • Modeling Languages Environments, Transformation Engine, etc. • Optimization Servers/Registries • Clients and Interfaces • Preprocessors/Analyzers • Optimization Solvers • Function Evaluators and Simulation Engines • Others? (Benchmark Problem Services etc.)
