Inventory research

The purpose of this paper is to provide a review of inventory management articles published in major logistics outlets, identify themes from the literature and provide future direction for inventory management research to be published in logistics journals. Articles published in major logistics articles, beginning inwhich contribute to the inventory management literature are reviewed and cataloged.

The articles are segmented based on major themes extracted from the literature as well as key assumptions made by the particular inventory management model. Two major themes are found to emerge from logistics research focused on inventory management. First, logistics researchers have focused considerable attention on integrating traditional logistics decisions, such as transportation and warehousing, with inventory management decisions, using traditional inventory control models.

Second, logistics researchers have more recently focused on examining inventory management through collaborative models. This paper catalogs the inventory management articles published in the major logistics journals, facilitates the awareness and appreciation of such work, and stands to guide future inventory management research by highlighting gaps and unexplored topics in the extant literature.

The problem can be modeled using mathematical techniques of optimal controldynamic programming and network optimization. The study of such models is part of inventory theory.

One issue is infrequent large orders vs. Large orders will increase the amount of inventory on hand, which is costly, but may benefit from volume discounts. Frequent orders are costly to process, and the resulting small inventory levels may increase the probability of stockoutsleading to loss of customers.

In principle all these factors can be calculated mathematically and the optimum found. A second issue is related to changes in demand predictable or random for the product. For example, having the needed merchandise on hand in order to make sales during the appropriate buying season s. A classic example is a toy store before Christmas : if the items are not on the shelves, they cannot be sold. And the wholesale market is not perfect' there can be considerable delays, particularly with the most popular toys.

So, the entrepreneur or business manager will buy speculatively. Another example is a furniture store. If there is a six-week, or more, delay for customers to receive merchandise, some sales will be lost. A further example is a restaurant, where a considerable percentage of the sales are the value-added aspects of food preparation and presentation, and so it is rational to buy and store somewhat more to reduce the chances of running out of key ingredients.

The situation often comes down to two key questions: confidence in the merchandise selling, and the benefits accruing if it does? A third issue comes from the view that inventory also serves the function of decoupling two separate operations. For example, work in process inventory often accumulates between two departments because the consuming and the producing department do not coordinate their work.

With improved coordination this buffer inventory could be eliminated. This leads to the whole philosophy of Just In Timewhich argues that the costs of carrying inventory have typically been underestimated, both the direct, obvious costs of storage space and insurance, but also the harder-to-measure costs of increased variables and complexity, and thus decreased flexibility, for the business enterprise.

The store has costs that are related to the number of items in store and the number of items ordered:. Inventory models can be based on different assumptions: [1] [2]. Although the number of models described in the literature is immense, the following is a list of classics:. From Wikipedia, the free encyclopedia. This section possibly contains original research.

Women make up only Women receive as much media coverage as male candidates; however the press is often sexist. Women raise as much money as men but must work harder.

Greater efforts are required to raise the same amount of money PACs led by men give less money to female candidates than male candidates Women seem to be less comfortable asking for money than men.

Fundraising is a deterrent for women when deciding to run for office Lack of PACs run by women aimed at female Republican candidates makes it more difficult for them to establish financial credibility early in the race Women as Donors Women give less often and in smaller amounts to political campaign Democratic women are more likely to give to female candidates than Republican women Women are less likely to be donors on a large scale Future Research How often do women decide not to run after encountering initial fundraising difficulties?

In Bologna, there was a guild of experts who appraised the objects in estates. In Rome, nothing similar seems to have existed, and notaries would consult individual artists to get a more precise idea of the value of certain objects.

Art historians have studied inventories extensively and enthusiastically in recent years. It should also be kept in mind that paintings are often listed in inventories with no reference to their provenance, dimensions, or value.

Even when this information does appear, it can be highly subjective: attributions are sometimes optimistic or, in any case, not particularly trustworthy, especially when they are more distant chronologically from the time in which a particular work of art was created. When specified precisely, measurements were usually given in palms a Roman palm was equivalent to approximately Values were indicated only occasionally and obviously were often a sign that the family wished to sell a particular work.

Reliability is the degree of consistency with which a test measures what it is said to measure. Test length greatly affects reliability coefficients, with longer tests traditionally producing higher scores.

For example, the well-researched Myers-Briggs Type Indicator reports internal consistency reliability for its four scales on general population samples to range from. Thirty day test-retest reliability produced scores ranging from. The validity scores of a test estimate how well the test measures what it purports to measure. Personality assessment tests usually produce validity scores for each of the individual traits measured.

When scores on the traits of a test correlate well with scores on similar traits on other tests, the test is said to have good concurrent validity. Thirty-two terms, primarily adjectives and short descriptive phrases derived through factor analysis, make up the item pool. The Inventory takes approximately ten minutes to complete and an additional five to ten minutes to score.

Item analysis establishes the statistical relationship between items of an inventory and the traits they measure. An initial sample of individuals completed the INSIGHT Inventory and a factor analysis of their scores was computed to select the items which loaded most heavily on the four factors scales. Reliability Reliability is the degree of consistency with which a test measures what it is said to measure. Validity The validity scores of a test estimate how well the test measures what it purports to measure.
