4.4.2 Computers and inventory management
Computing power remains the platform on which all modern inventory management systems depend. Special software is constantly being developed and integrated to manage inventory; and computing hardware provides more and more effective computers on which to run the software. When bar coding, for example, RFID and GPS are linked together with a wider management system, and a streamlined logistics management process evolves. Within this process specific components can be identified for which specialised software is used. Examples include warehousing management systems, terminal operations management systems, yard planning and control systems, equipment control systems, vehicle booking systems and so forth. With suitable software, communications between the various nodes of the logistics chain (warehouses, terminals, workers, planners, etc.) is maintained by the use of radio signals. The labour intensive practice of updating information has been replaced with technology that carries out the mundane tasks of counting, recording and transmitting information.
Intelligent transport systems (ITS). Intelligent transport systems are complex IT related technologies applied to various transport and logistics functions. They include traffic, transport and commercial vehicle operating systems using powerful computing and control functions like collision avoidance, ground sensors to maintain track of movement, video camera linked vehicle management, electronic guidance systems, automatic vehicle location and GPS. This is new technology that is making inroads into warehousing and terminal operations. The ability to implement these systems is controlled not by what is technologically possible but by what government policies will allow, and social tolerances to technology will accept. The use of these technologies is expected to contribute to greater reliability in the logistics chain and reduce costs to users as well as management.
The integration of the various technologies is contributing strongly to overall management of the logistics chain. New opportunities for conducting operations are offered and are being used. The capacity and productivity of operations are being consistently improved as are the time and cost of operations.
