Logistics is the management of the flow of resources, between the point of origin and the point of destination in order to meet some requirements, for example of customers or corporations. The resources managed in logistics can include physical items as food, materials, equipment, liquids and staff as well as abstract items as information, particles and energy. The logistics of physical items usually involves the integration of information flow, material handling, production, packaging, inventory, transportation, warehousing and oftentimes security. Furthermore the complexity of logistics can be modeled, analyzed, visualized and optimized by dedicated simulation software. Minimizing time and use of resources, are common goals.
