To speak ‘Biological Computer Laboratory’ also speaks ‘Heinz von Foerster.’ To invoke von Foerster also invokes the BCL community that he gathered through his unerring identification of original thinkers and his unparalleled clarity about second-order cybernetics. Having chosen well his lab’s collaborators, von Foerster contributed seminal thinking that became foundations and superstructures for practitioners in the generations that followed.

The design of a complex regulator often includes the making of a model of the system to be regulated. The making of such a model has hitherto been regarded as optional, as merely one of many possible ways.

Keywords: cybernetics, systems theory, the VSM, Viable System Model, project management, complex systems analysis
The paper is made to understand modern (especially cybernetic) methods of complex systems analysis and management, to explain scientiﬁc basis of the Viable System Model, to compare theoretical model with developed project management system in Company.

This paper is concerned with the organization and the operational viability of Solid Waste Management Authorities (SWMA). The frequently changing performance requirements, the continuous search for alternative technological, financial and institutional options, the unstable market of recyclables, the variations in waste characteristics, and the need for public-private partnerships are only some of the factors that shape and drastically affect the operating environment of a SWMA. Consequently, for any such Authority (be it a small
municipal department or a huge organization serving a megapolis), there is an emerging need for:
Enterprise-architecture, service-architecture and the Viable System Model
Tom Graves : Tetradian Consulting
– enterprise architects, service architects, operations
strategists, process analysts, IT-systems analysts
– increase business take-up of enterprise architecture
– demonstrate tools to review service-architecture
– extend enterprise-architecture beyond IT-systems
– extend service-architecture across all service types
– use ‘systems-theory’ tools to improve services
– business benefits of extended architecture

The Viable System Model (VSM) is recursive and helps explaining the general production management model of the ERP system. The recursion level explains the development
starting from warehouse management to Material Requirement Planning (MRP), to Manufactory Requirement Planning (MRPII), to Enterprise Resources Planning (ERP), and
to Supply Chain Management (SCM).
In each recursion level, the emergent concepts helps explaining the discovery of the two categories of demand: independent demand and dependent demand, the feedback concept
helps explaining the closed cycles in ERP, the local, future and total environment concept helps explaining the interactions between the market and the Production System and the
Law of requisite variety helps to manage complexity.
In Antarctica in January, 2013 – the summer at the South Pole – scientists released 20 balloons, each eight stories tall, into the air to help answer an enduring space weather question: when the giant radiation belts surrounding Earth lose material, where do the extra particles actually go? This NASA-funded mission is called BARREL, for Balloon Array for Radiation belt Relativistic Electron Losses. Each balloon launched by the BARREL team floated for anywhere from three to 40 days, measuring X-rays produced by fast-moving electrons high up in the atmosphere.BARREL works hand in hand with another NASA mission called the Van Allen Probes, which travels directly through the Van Allen radiation belts. The belts wax and wane over time in response to incoming energy and material from the sun, sometimes intensifying the radiation through which satellites orbiting Earth must travel. Scientists need to understand this process better, and even provide forecasts of such space weather, in order to protect our spacecraft.› Read MoreImage Credit: NASA Read More
