  • Publication number: 20170147964
    Abstract: A method of reallocating inventory in a fulfillment network is disclosed herein. The fulfillment network can include a plurality of distribution centers. An allocation plan can be created in a one of a variety of different manners, where the allocation plan involves allocating an item to one or more distribution centers in the fulfillment network. Thereafter, the allocation plan can be analyzed for feasibility. If the allocation plan is not feasible, each distribution center in the allocation plan can be analyzed to determine if using the distribution center is feasible. If the distribution center cannot be used, another distribution in the same cluster of distribution centers is examined for feasibility. This process is repeated for each distribution center in the allocation plan. Once an alternative allocation plan has been developed in this maimer, items can be allocated. Existing inventory can be taken into account in the allocation plan.

  • Publication number: 20140304453
    Abstract: This invention discloses methods for implementing a flash translation layer in a computer subsystem comprising a flash memory and a random access memory (RAM). According to one disclosed method, the flash memory comprises data blocks for storing real data and translation blocks for storing address-mapping information. The RAM includes a cache space allocation table and a translation page mapping table. The cache space allocation table may be partitioned into a first cache space and a second cache space. Upon receiving an address-translating request, the cache space allocation table is searched to identify if an address-mapping data structure that matches the request is present. If not, the translation blocks are searched for the matched address-mapping data structure, where the physical page addresses for accessing the translation blocks are provided by the translation page mapping table. The matched address-translating data structure is also used to update the cache space allocation table.
