Nearly all known biological warfare agents are intended for aerosol application. Although less effective as potable water threats, many are potentially capable of inflicting heavy casualties when ingested. Significant loss of mission capability can be anticipated even when complete recovery is possible. Properly maintained field army water purification equipment can counter this threat, but per...

Russia's attack on Ukraine provoked a reaction from Western states, which jointly pledged to provide aid the fighting Ukraine. The attitude of countries is very important in terms Ukraine's independence. Military support, despite its large scale, probably insufficient for Armed Forces are now completely dependent supply weapons, military equipment and other materials countries. Ukrainian army c...

This study compared three methods for creating the most centered staging platform (SP) around separated instruments (SI) in curved canals. Green .04 ProFiles, notched at D(3), were separated in the apical third of 42 mesiobuccal canals of maxillary and mandibular molars. Teeth were divided into three groups. SPs were prepared in group 1 with Gates Gliddens (GG) to a size #3; group 2 with LightS...

We find that raw materials inventories in the manufacturing sector in the 1970s and 1980s and 1990s were two to five times higher in developing countries than in the United States, despite the fact than in most developing countries real interest rates are at least twice as high. Given the high costs of capital in most developing countries, the impact of those high inventory levels on the cost o...

This article focus on the behaviour of a multi-product batch production line with fixed capacity which is scheduled according to inaccurate inventories (IRI). We assume an unlimited supply of raw materials and a constant demand for the different finished goods. The ordering policy of this production line is based on a (Q,R) continuous review, lost-sales inventory model and on given priority for...

In many industrial sectors, firms are dealing with a demand which is more and more uncertain often due to the supply chain structure. One of the most critical effects of demand uncertainty is the simultaneous increase of inventories and decrease of customer service. This work describes an integrated system for managing inventories in a multi-echelon spare parts supply chain, in which customers ...

This study uses survey data on several hundred automotive suppliers in North America to evaluate the determinants of inventory levels in high-volume discrete parts manufacturing. We assess the magnitude of raw materials, work-in-process, and finished goods inventories, as well as production lot sizes and through-put times. Results are broadly consistent with the EOQ formula and related models o...

We consider a manufacturing system with preventive maintenance that produces a single part type. An inventory is maintained according to a machine age dependent hedging point policy. We conjecture that, for such a system, the failure frequencies can be reduced through preventive maintenance resulting in possible increase in system performance. Traditional preventive maintenance policies, such a...
