  • Patent number: 10489740
    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 manner, items can be allocated. Existing inventory can be taken into account in the allocation plan.

  • Publication number: 20190345033
    Abstract: A high-purity chlorine dioxide gas may use hydrogen peroxide as a reducing agent and may use horizontal generator, evaporation crystallizer, dryer and other devices to produce chlorine dioxide gas (product) and sodium sulfate (by-product). Compared to the conventional chlorine dioxide preparation system, the chlorine dioxide reaction and the sodium sulfate crystallization are performed in two processes. These processes are relatively separate and independent, and continuously produce chlorine dioxide gas with high purity and low moisture content while the by-product salt cake is evaporated, crystallized, filtered and dried, thereby producing sodium sulfate, without generating solid and liquid waste.
