The scheme of the Supply Management Sub-system architecture

The ISL manages logistic activities, items, stocks and transactions. The stocks can be found in warehouses, in units, in movement between warehouses and units, and in the process of receiving (stock comes into the armed forces) or process of consumption and disposal (stock gets out of the armed forces). Logistic activities (like maintenance, provisioning, etc.) are also done at different levels of the armed forces.

The main concept is to allow independent work in different sites, but managing logistics in a central armed forces system. This concept lets each site (warehouse, unit or troop recording department) manage stocks and record transactions without regarding to the availability of communications to the central site. On the other hand, the central files will be updated (on-line or by batch) for every transaction, thus allowing to maintain a centralized logistics management, and capability for the provisioning and acquisition of stocks.

To meet the above mentioned concept the ISL is designed as a centralized distributed system. A network of servers is deployed over all the country including extraterritorial locations. The servers are interconnected by WAN, telephone lines or, when electronic connection is not available, data are distributed by a suitable memory medium like CD ROM. Databases in all servers are updated by the sophisticated utility ”Data Distribution” so that information in all locations is always consistent and up-to-date.
