As Supply chain (German: Delivery chain, logistic chain or also creation of value, creation of value chain, value system) a enterprise-spreading virtual organization thing (network) is designated, which brings specific economic goods out for a defined goal market as efficiency bonus plan which can be regarded collectively.
Examples of Supply chain are for instance the delivery chains of the automobile industry or the textile creation of value chain. In the extreme the Supply chain can thereby from the raw material extraction to the recycling (sometimes also the disposal) of old products is enough (from dirt ton dirt). The interorganisationale division of labor between the independent enterprises involved defines expansion and structure of the Supply chain. By the tendency for concentration on core authority (outsourcing, decrease of the intraorganisationalen division of labor) increasingly more differentiated (i.e. arbeitsteiligere) Supply chain develops.
In the result not vertically integrated single manufacturers compete, but on the respective goal markets instead structured complex alternative creation of value systems (delivery chains), which consist of systemically connected, but autonomously acting business units. Competition advantages attain such decentralized organized value systems esp. by an market-adequate configuration of their structure as well as by a superior co-ordination of the autonomously steered activities in the Supply chain.
The Supply chain management (SCM) aims in this sense at a long-term (strategic), medium-term (tactical) and short term (operational) improvement of effectiveness and efficiency of industrieller creation of value chains off. Alternatively also the terms supplying chain management and delivery chain management are used.
SCM and logistics are often synonymously used. Indeed SCM aims such as logistics at the organization of object rivers (goods, information, values) along the process stages of the delivery chain, whereby they aim at an increase (END) of the customer use (effectiveness) and at a system-far improvement use/cost relationship (efficiency). In particular during transport and storekeeping in the enterprise the transition makes a qualitative jump the modern Supply chain management. While logistics regarded the object rivers to a large extent independently of institutional questions, the SCM refers the structuring and co-ordination of autonomously acting business units in a creation of value system explicitly into the analysis. The SCM stresses thus in demarcation to logistics the interorganisationalen aspect of the logistic task of management.
The special characteristics (entire) of the system "Supply chain "result from specific dynamic cooperating of the delivery track links. These system properties cannot be derived from the sum of the characteristics of the single members involved, on the contrary new characteristics of the overall system step out as result of complex dynamic processes (Emergenz). The scientific argument with the SCM supports itself therefore (which concerns those formally/mathematical side) strongly by the realizations of the system theory as well as the chaos and complexity research from economical view finds with the analysis of SCM problem definitions in particular explanation beginnings of the new (transaction cost theory, theory of the rights of disposal, principle aluminum agent theory) as well as the resources Based View application.
Characteristic problem definitions of the Supply chain management are for example:
As in former times expression of the turn of the industry to SCM concepts those can be regarded about 1980 using Just in Timemovement (JIT). JIT aims at a temporally closely coordinated coupling of the production processes of manufacturer and supplier. Special attention found this concept in the automobile industry. A condition for a successful conversion of the JIT thought were apart from purposeful making flexible and qualitative stabilization of the achievement processes on the delivery side in particular the logistic coupling of the production processes of supplier and manufacturers over the consumption determination, through large renouncement of stocks as problem buffers, as well as using standardized charge carriers and processes. Exemplary meaning attained the Kanban control coming from Japan in this connection (Pull principle in the production control).
In the trade and in the consumer goods industry the Supply chain management manifests itself in particular as part of the Efficient Consumer Response concept (ECR). Here it concerns a industry-far initiative to the optimal offer structure for consumers in trading firms with simultaneous rationalization of Supply chain processes. The concept building relies on a set of specific fundamental technologies (e.g. bar code, standard for electronic data exchange), logistic standard processes (e.g. CROSS Docking, VMI=Vendor Managed Inventory or CO-Managed Inventory) and a process of marketing-oriented offer optimization: Category management, which is linked in a spreading common planning process (CPFR, Collaborative Planning, Forecasting and Replenishment).
A industry-spreading initiative of relevant large-scale enterprises created Supply chain with the development operation of the Reference of model (SCOR model) the basis for the modelful representation, the power measurement and the efficiency comparison as well as for the Reengineering of Supply chain processes. The SCOR model wants to facilitate communication over Supply chain structures and Supply chain processes between the enterprises involved, by creating a general conceptual and conceptional reference framework for this.
Specific software systems, which are directed toward operational planning and controlling of the Supply chain activities, find increasing employment. These systems become bspw. Advanced Planner and Optimizer (APO), APS system (Advanced Planning and Scheduling) or also as ERP II systems calls. As operators of such planning systems in particular large electronic market places offer themselves.
Software, which supports SCM, tends recently to it to represent the condition of the delivery chain in (almost) real time. In addition the goods seized along the chain on determined (delivery) points by BDE systems. This can take place e.g. via scanning of an individual bar code or via vintages RFID tags. By the possibility of the linkage of these real time data also in the system deposited being exists the possibility with the help of a Supply chain Event management (SCEM) purposefully in the logistics system to intervene to be able.
The transport costs sank by the liberalisation and the Ausflaggen, therefore the transportation expenditure per volume around unit or Masseneinheit plays no role in that of JIT systems often planning particularly produces however two substantial problems in practice:
Telematics systems can intervene here lindernd without however the problems at the root to pack. Clear defaults the pressure create remedy for co-operation under the suppliers exercise and a minimizing the risk by introduction of additional criteria when planning of the creation of value chain. Regional reduces the latencies, increases thus the controllability of the system and decreases the risk of long routes of transportation.
