Life Cycle of Item of Supply
The capabilities of the ISL support an item of supply during the whole life cycle of materiel. The basic scheme of the item life cycle supported by the ISL functions is depicted on the diagram.
The Provisioning compares the current inventory level (from the Materiel Record Keeping) with the norms for units, formations, etc. (from the Logistic Requirements) and as the result calculates the future needs of the armed forces. This result is corrected according to a budget taken for example from the PPBS (Planning, Programming and Budgeting System). The corrected result is submitted for implementation to the Acquisition and Procurement Directions and information concerning the surplus or useless materiel enters the Disposal.
The Acquisition and Procurement Directions sum the directions created in the Provisioning according to possible suppliers and create requirements for the acquisition centre. The data about a concluded contract enter the Acquisition and Procurement Directions where they are followed. The information about expected supplies is then distributed to the Receiving on the individual servers.
The Receiving supports the process of receiving of materiel from civil organizations to the armed forces. It compares incoming materiel with contracts and creates reports about fulfillment of the contracts for the Acquisition and Procurement Directions. The Receiving also generates data, so called transaction documents, which are sent using modules of the Materiel Record Keeping to the Financial Information System for accounting purposes.
The Storage supports activities performed in warehouses like storing items in a proper location, stocktaking, etc.
The Disposal processes materiel to be disposed of.
The Distribution Directions create directions for the complementing of the inventory level according to the amount standard defined for each organizational unit of the armed forces. These directions are the input for the Issuing.
The Issuing creates plans for issuing according to the directions obtained from the Distribution Directions. It supports a process of collecting materiel from a warehouse and prepares data about the collected materiel for the Movements and Shipments.
The Movements and Shipments support the process of packing, completion and shipping shipments. It monitors physical movements of materiel amongst the organizational units of the armed forces and provides the Materiel Record Keeping with data – transaction documents, for accounting in the Financial Information System.
Issued and distributed materiel is used, maintained and consumed in the armed forces and information about the actual inventory level is used by the Provisioning for new calculation of armed forces’ needs.
