Databases, resource allocation

Pull-based ATP Models Pull-based ATP models perform dynamic resource allocation in direct response to actual customer orders. Models of this type can range from a simple database lookup to sophisticated optimization. The purpose of pull-based ATP models is to make best use of available resources (including raw materials, work-in-process, finished goods, and even production and distribution capacities) to commit customer order requests over a period of time across a supply chain. The time horizon in pull-based ATP models is usually so short that a company can assume full knowledge about the availability of production resources. Pull-based ATP models are responsible for matching complicated customer requests with diversified resource availability. The specific decisions usually involve which orders to accept and, for each order, what quantity and which due date to promise. 

Consideration of feasibility of control. National authorities sometimes debate whether resources should be allocated to monitoring chemicals that the country or water supply organization lacks the resources to control. Depending on the potential for adverse health effects, it is often desirable to build up a water-quality database so that an informed analysis can be made of the costs and benefits of controlling such chemicals. 

Can the need for PMV be accurately predicted Early identification of patients likely to require PMV is of considerable interest as allocation of ICU resources and timing of decisions to perform tracheostomy and transfer to a long-term care may be facilitated. Using clinical judgment alone at ICU day 7, the ability to predict need for MV at 21 days was no better than a chance (76). Utilizing the APACHE III database of nearly...
