Inventory-related metrics

INVENTORY-RELATED METRICS Inventory-related decisions affect the cost of goods sold, the C2C cycle, the assets held by the supply chain, and its responsiveness to customers. A manager should track the following inventory-related metrics that influence supply chain performance ... 

The chemicals stored in the inventory can be searched by exact structure, substructure, or similarity [26], Similarity searching aims at retrieving compounds that are similar to a query compound by one or more measures of similarity. A set of structural features of the target molecule is compared with those of each chemical in the database, generating a similarity measure by a chosen metric such as the Tanimoto coefficient [27]. More details about chemical similarity are given below in relation to the chemical similarity tool. 

Just over 20% of the electricity generated in the United States is produced by nuclear power plants. In 1995, 32,200 metric tons of spent fuel, with a total activity of 30,200 MCi, was stored by the electric utilities at 70 sites (either in pools or in dry storage systems) (Ahearne 1997, Richardson 1997). By 2020, the projected inventory will be 77,100 metric tons of heavy metal (MTHM) with a total activity of 34,600 MCi. Although the volume of the spent fuel is only a few percent of the volume of HLW, over 95% of the total activity (defense-related plus commercially generated waste) is associated with the commercially generated spent nuclear fuel (Crowley 1997). At present in the United States, none of the spent fuel will be reprocessed all is destined for direct disposal in a geological repository at Yucca Mountain, Nevada (Hanks et al. 1999).
