  • Patent number: 7853466
    Abstract: Methods, systems and computer program products for supporting supply chain facility performance analysis. Methods include maintaining supply chain facility configuration information for a plurality of supply chain facilities. The method also includes identifying variables that are attributed to performance of the supply chain facilities. Data corresponding to one or more of the variables for selected supply chain facilities in the plurality of supply chain facilities is collected. Performance analysis is performed for the selected supply chain facilities using the data as input. The performance analysis includes executing a data envelope analysis (DEA) based three-stage performance analysis model, executing a statistical analysis and executing a sensitivity analysis. The results of the performance analysis are output. The results include a performance ranking of the selected supply chain facilities, a prescription for performance improvement, a correlation analysis, and a sensitivity analysis.

  • Patent number: 7325845
    Abstract: A latch assembly includes a plunger having a ramp and a lip, with a support member defining an opening through which the plunger extends. A support surface partially defines the opening and supports the plunger. The plunger is selectively movable between an extended position, in which the plunger protrudes a first distance from the opening, and a retracted position, in which the plunger protrudes a second distance from the opening, with the second distance being less than the first distance. In the extended position, the ramp and the lip are on a first side of the opening. In contrast, in the retracted position, the ramp and the lip are on a second side of the opening, with the lip engaging the support member to maintain the retracted position.

  • Patent number: 7280977
    Abstract: The present invention provides a model for assessing performance of a dynamic collaborative relationship. The present invention provides a method of modeling dynamic relationships by inputting data related to the collaborative relationship into a model, which comprises a plurality of components key to the collaborative relationship. Each of these components is interrelated with the model, and the model generates a value indicative of a condition or performance of the relationship. The relationship value can be analyzed by comparison with baseline values correlated to exemplary collaborative relationships. The present invention further provides methods of developing a model capable of assessing dynamic collaborative relationships.

  • Patent number: 7121603
    Abstract: A sliding load floor assembly for a motor vehicle comprises a sliding platform configured to receive a load floor and slidable along a support frame fixed to the vehicle. The support frame includes upper and lower flanges. An axle extends outward from the sliding platform, with a roller rotatably attached thereto and movable along the upper and lower flanges. The roller configuration elevates the sliding platform above a vehicle floor, while allowing the sliding platform the move between a stowed position and an extended position. A wedge is configured to exert a vertical force upon a portion of the sliding platform in the stowed position, thereby preventing vertical movement of the roller to reduce vibration. At least one detent member and at least one latch member are selectively engageable with one another to restrict movement of the sliding platform with respect to the support rail.
