Extended organisational learning methods for the reduction of unrequested nonlinear dynamic effects in supply networks
In logistics networks with close interdependencies and large flexibility requirements still unwanted nonlinear dynamic effects in the development of the inventory numbers arise - in pure delivery networks this effect is called Bullwhip-effect. The research within this range divides into two different approaches. The so called normative research approach looks for the reasons in the system, e.g. in system internal time delays and suggests as counter measures regulation strategies, which are directed toward the overall system and not on individual enterprises, and thus are accompanied by a restriction of the freedom of choice of the individual enterprises.
The descriptive research approach however looks for the reasons for the Bullwhip-effect in the limited rationality of the decision makers. Therefore among other things it comes to an underestimation of the supply lines. As counter measures here different learning strategies were developed. In the long run to the instabilities can only be worked against with by elements of both approaches lastingly. Basic questions with the linkage of both approaches are: which causes can be eliminated with which of the two approaches best or possibly exclusively? A goal of this research project is the development and study of a integrative, holistic and adaptive regulation and learning strategy for the lasting reduction of instabilities in delivery networks.
