Inventories and transfers accounting of raw materials and oil as well as semi-finished and finished products is a key point of production management and is a base for overall financials. Transfers modelling and its measurement accuracy directly influences quality of production volume and calendar scheduling. For continuous processes (like petro and petro-chemical industries), this includes calculation and monitoring of oil and gasoline products pumping as well as tank balances at the end of the day or shift. For batch processes (like in metals, chemical and other industries) important things include monitoring of movement and stocks of raw materials, semi-finished and finished products as well as stocks in all locations (intermediate stockpiles and raw materials receiving/finished products shipping warehouses)
