Distribution center, failure

In the second quarter of 2008, Levi Strauss Company s net income dropped by 98 percent because of the failure of an IT project for ERR Three U.S. distribution centers were forced to close for a full week and the company took a f 92.5 million hit to its bottom line. David Bergen, chief information officer, was forced to resign. ... 

In January 2008, Walmart announced its first real compliance penalties for failure to tag products, specifically for shipments to its Sam s Club chain. Walmart said in a letter to suppliers that a failure to tag pallets sent to its distribution center (DC) in DeSoto, Texas, or directly to one of its stores served by that DC after January 31 would be charged a service fee, starting at 2 per untagged pallet on February 1, 2008, and capping at 3 per pallet on January 1, 2009. 

Failure to understand the underlying patterns and the reasons for variances — Business people generally do not make enough use of the information they have in collective databases to improve the accuracy of sales forecasts. In a typical retail firm, for example, there is data on trade sales and marketing results, retail store transactions, warehouse and distribution center releases, and promotional results, all of which could span five or more years, only a portion of which is integrated into the forecasting process.

The finished packaged product is shipped by various methods to distribution centers and care centers. During shipping, the carton undergoes random vibration, which causes the folds and creases to flex repeatedly. While this was observed to lead to some deformation and deterioration of the film surface at the tip of a crease, flexing of the creases alone did not lead to panel leak formation, except under very extreme vibration conditions. Under those conditions, however, the failure morphology was very different from the panel leaks observed in the field. Again, crease formation and/or vibration (either alone or in combination) did not lead to panel leak formation. 

If estimated of distribution parameters are desired from data plotted on a hazard paper, then the straight line drawn through the data should be based primarily on a fit to the data points near the center of the distribution the sample is from and not be influenced overly by data points in the tails of the distribution. This is suggested because the smallest and largest times to failure in a sample tend to vary considerably from the true cumulative hazard function, and the middle times tend to lie close to it. Similar comments apply to the probability plotting.

Williams (49), Ward (79), and Jancar et al. (89) proposed an approximate model of mixed mode of fracture to account for the effect of finite specimen dimensions for Kc and G, respectively. The basic idea in both theories is a substitution of the actual distribution of fracture toughness across the cross-section by a simple bimodal distribution, assuming plane strain value in the center and plane stress value at the surface area of the specimen. Size of the plastic zone IR relative to the specimen width B gives the contribution of plane stress regions and is a measure of the displacement of the state of stress at the crack tip from the plane strain conditions. Note that this approach can be used only if the mode of failure does not change with the test conditions or material composition (i.e., it attains its brittle character). 

Despite these advances, however, many of the logistical problems faced in emergencies are not caused by shortages of medical and technological resources but rather by failures to coordinate their distribution [30], with significant possibilities for error and destruction, as occurred at the New York s World Trade Center command post on September 11, 2001 [31-32]. 

H. M. Clearfield joined Martin Marietta Laboratories in January, 1985. Since then, he has primarily investigated surface and interfacial phenomena in adhesive bonding, including surface preparation of titanium alloys for structural applications at high service temperatures, mechanisms of bond failures that occur at high temperatures, and bonding of the thermal protection system to the space shuttle external tank. Additionally, he has investigated dopant depth distributions in ion-implanted and laser-annealed silicon. Dr, Clearfield is supervisor of surface analysis facilities at Martin Marietta Laboratories. Recently, Dr. Clearfield joined IBM s T. J. Watson Research Center. 

The imiformity and stability of nanotube dispersion in polymer matrix are probably the most fundamental issue for the performance of composite materials. A good dispersion and distribution of CNTs in the polymer matrix minimizes the stress concentration centers and improves the uniformity of stress distribution in composites [80]. On the other hand, if the nanotubes are poorly dispersed within the pol mier matrix, the composite will fail because of the separation of the nanotube bundle rather than the failure of the nanotube itself, resulting in significantly reduced strength [117], Mazinani et al. studied the CNT dispersion for electrospun composite fiber, as well as its effect on the morphologies and properties of electrospun CNT-polystyrene nanocomposite [42]. They demonstrated that the CNT dispersion is an important controlling parameter for final fibers diameter and morphology.
