Since its development in the Japanese automotive industry, Lean Management has essentially supported enterprises with the elimination of waste. Waste, among others, occurs by means of overproduction, idle times of people and machines (waiting for the next production step), unnecessary transports, an oversized stock of inventory and defective products. Each form of waste represents a consumption of resources without getting any service in return, as the customer is not willing to pay a higher amount for it. Taiichi Ohno (one of the two fathers of the Toyota Production System) already postulated this in his homonymous book: Each form of wastage has to be avoided as possible. The factor time and the control of complexity and dynamics become more and more important, not only out of the Lean Management's point of view. The Just-in-time (JIT) approach and the connection of activities and processes to continuous running, demand-driven flows of information and material within supply chains (SC), do reflect this change. The flow is understood as a metaphor to whose ideal - which is a continuous, uninterrupted flow - the processes should be orientated. Current analyses deal with models and methods for a continuous and smooth flow of material in SCs. By means of a resolution of 'barrages' (production without taking any inventories), idle times can be eliminated, which thereby supports the Lean-approach. The basic edition about science discipline of Cybernetics appeared in 1948 by Norbert Wiener. The title of the book is: Cybernetics or Control and Communication in the Animal and the Machine'. Nowadays, cybernetics is further distinguished, among others, within the systems theory and control engineering. Fundamental ideas and concepts of cybernetics are also applied in economics, e.g. in a cybernetic oriented modelling and an experimental simulation of economic processes. Cybernetics is understood as a formal science of the structure, relations and the behaviour of dynamic systems. Within this article the analysis of formal cybernetic principles occurs for a stable operation in order-related production networks (OPN).
