Inventory constitutes a major component of working capital. To a large extent, the success and failure of a business depends upon its inventory management performance. The basic objective of inventory management is to optimize the size of inventory in a firm so that smooth performance of production and sales function may be possible at minimum cost. Galloping inventories in recent years, the cr...

We study the value of component commonality in a periodic review assemble-to-order system, introduced by Akçay and Xu in 2004, where an independent base stock policy and a first-come-first-served allocation rule are used, and the base stock levels and the component allocation are optimized jointly. We show that lowering component commonality may yield a higher type-II service level. The lower d...

As advancing technology makes Flexible Manufacturing Systems (FMS's) a viable option for an increasing number of firms and products, determining their economic value has become increasingly important. Despite considerable research in this area, the effect of the ability or inability to hold interperiod inventories on the value of FMS's has received relatively little attention. This paper propos...

Finland’s forest resources have been investigated by means of National Forest Inventories since 1921. The inventories have produced a detailed picture of forest resources and the state of forests as well as long time series. Although the structure of the growing stock and the forest balance have been the most important characteristics, the whole scope is much wider, including information on for...

I examine the behavior of inventories and their role in the short-run dynamics of commodity production and price. Competitive producers of a storable commodity react to price changes by balancing costs of changing production with costs of changing inventory holdings. To determine these costs, I estimate a structural model of production, sales, and storage for copper, heating oil, and lumber. I ...

Practical intelligence as measured by tacit-knowledge inventories generally has shown a weak relation to other intelligence constructs. However, the use of assessments capturing specialized, job-related knowledge may obscure the generality of practical intelligence and its relation to general intelligence. This article presents three studies in which three new everyday tacit-knowledge inventori...

[1] We evaluate the suitability of a three-dimensional chemical transport model (CTM) as a tool for assessing ammonia emission inventories, calculate the improvement in CTM performance owing to recent advances in temporally varying ammonia emission estimates, and identify the observational data necessary to improve future ammonia emission estimates. We evaluate two advanced approaches to estima...

One of the key components regarding heat transfer and tritium inventories in deuterium-tritium nuclear fusion reactors is the (tritium) Breeding Blanket, called Test Blanket Module or TBM in ITER experiment. Several designs are going to be tested in ITER, one of those is the HCLL (Helium Cooled Lithium Lead) design. Before being tested, it is of major interest to predict in detail several flow ...

This study quantitatively estimates the spatial distribution of anthropogenic methane sources in the United States by combining comprehensive atmospheric methane observations, extensive spatial datasets, and a high-resolution atmospheric transport model. Results show that current inventories from the US Environmental Protection Agency (EPA) and the Emissions Database for Global Atmospheric Rese...
