• Basic processes, such as warehous<strong>in</strong>g or orderpick<strong>in</strong>g processes, <strong>in</strong> the sense of process modules oreventually even generic reference processes;• Complex processes composed of basic processes andoperations.However, separation of precisely those basicprocesses is only done accord<strong>in</strong>g to the flow of objects.In future, it will also be necessary to identify autonomousprocesses by their control tasks, which is expected to leadto new k<strong>in</strong>ds of basic processes and an eventuallymodified syntax for compos<strong>in</strong>g complex processes ofavailable operation and process components. To def<strong>in</strong>erespective rules and regulations and to identify andspecify the new process components, these are subjectsof ongo<strong>in</strong>g research.CONCLUSIONSThe <strong>in</strong>creas<strong>in</strong>g <strong>in</strong>terl<strong>in</strong>k<strong>in</strong>g <strong>in</strong>side the supply cha<strong>in</strong>enabled by complex <strong>in</strong><strong>format</strong>ion technology systemsmakes new demands on logistics systems. New materialand <strong>in</strong><strong>format</strong>ion flow technologies have to ensurematerial flow track<strong>in</strong>g and trac<strong>in</strong>g as well as controlwithout any gap and close to real-time. Radio FrequencyIdentification (RFID) technology offers a possibility forl<strong>in</strong>k<strong>in</strong>g material and <strong>in</strong><strong>format</strong>ion flows at a control andmanagement layer as low as possible. Even today, RFIDis already used <strong>in</strong> parts of the retail bus<strong>in</strong>ess processcha<strong>in</strong>; <strong>in</strong> future article movements and account<strong>in</strong>goperations across the entire process cha<strong>in</strong> shallautomatically be recorded and documented (see Figure2).Application of RFID <strong>in</strong> logistics allows and requiresnew control systems and autonomous, decentralizedcontrol strategies which <strong>in</strong>dependently and flexibly adaptthemselves to chang<strong>in</strong>g environmental conditions andconcurrent objectives <strong>in</strong> special logistics doma<strong>in</strong>s (seeScholz-Reiter et al. 2005). In this context, the term<strong>in</strong>telligent logistics pops up mean<strong>in</strong>g <strong>in</strong>telligent logisticsobjects that autonomously and self-controlled movethrough logistics networks. Here, an <strong>in</strong>telligent logisticsobject knows its position and state, perceives itsenvironment, and reacts accord<strong>in</strong>gly, can communicatewith its surround<strong>in</strong>gs, or – <strong>in</strong> case of miss<strong>in</strong>gcommunication – act autonomously and purposefully.Intelligent logistics objects f<strong>in</strong>d their way through thematerial flow on their own and f<strong>in</strong>ally control or organizethe own flow autonomously. For this, resources are<strong>in</strong>dependently allocated and the objects organize localstrategies. Plann<strong>in</strong>g and control processes are shiftedtowards the layer of the physical material flows. Forrealiz<strong>in</strong>g this, the supply cha<strong>in</strong> partners or logisticsoperators need to fulfil a number of requirements, suchas:• Common standards concern<strong>in</strong>g processes, measures,data collection;• New control concepts <strong>in</strong>clud<strong>in</strong>g active action andnavigation or event-oriented navigation, plann<strong>in</strong>g,controll<strong>in</strong>g <strong>in</strong> dependence on the state of thelogistics objects and the process cha<strong>in</strong>.Apart from effects on software design andfunctionality as well as hardware requirements, such ascompletion of a system element’s control component bya decision <strong>in</strong>stance, also effects on the processes andtheir design turn out. However, these effects are expectedto be less related to the physical process structure but tothe logical process structure <strong>in</strong>stead. In future, the lattermight be shaped stronger by decentralized control andmanagement concepts based on self-control and processautonomy. With regard to process design, this goes <strong>in</strong>l<strong>in</strong>e with strengthen<strong>in</strong>g the approach of hierarchicalmodell<strong>in</strong>g and process development, but requires furthermethodological development. In addition to this, genericmeasures and characteristics are needed to supportassessment and selection of process structures.1 23456789999manufacturerdistribution centermarket/shop1 – attach<strong>in</strong>g transponders whilst manufactur<strong>in</strong>g2 – pack<strong>in</strong>g products <strong>in</strong>to boxes;order pick<strong>in</strong>g3 – automatically controll<strong>in</strong>g outgo<strong>in</strong>gconsignments4 – controll<strong>in</strong>g trucks for article protection5 – automatically controll<strong>in</strong>g and account<strong>in</strong>g <strong>in</strong> theMaterial Management <strong>Systems</strong> (MMS)6 – automatically sort<strong>in</strong>g, count<strong>in</strong>g, controll<strong>in</strong>gthe stock7 – automatically controll<strong>in</strong>g the consignment <strong>in</strong>the transshipment area8 – transparent article movement from the marketstorage to the retail<strong>in</strong>g area9 – check<strong>in</strong>g availability (stock-tak<strong>in</strong>g) andarticle protectionFigure 2.
