Features related to systems and methods for network planning based on optimization modeling of equipment and item transmissions. The network planning may include a model to plan for transmission of items over a network to maximize overall efficiencies over alternative transmission modes. The model may produce a network plan that schedules transmissions, determines the number and types of equipment needed to support the transmissions, assigns equipment to specific locations, and optimally routes items throughout the network.

Network planning and optimization

Techniques for heuristic customer order fulfillment planning. A method may include iteratively partitioning ordered items into shipment groups according to a set partition algorithm. Of a working set including the unassigned items, the algorithm may determine the subset that optimizes fulfillment cost per member of the subset, and may assign this subset to a shipment group. To determine the subset, the algorithm may iterate over the set of combinations of fulfillment decision variables. For each combination, a list of members of the working set that may be shipped according to the combination is generated. The subset of this list that optimizes, per member of the subset, the costs of shipping according to the combination is then identified.

Heuristic methods for customer order fulfillment planning

A method and system for determining analyzing an inventory purchasing opportunity with respect to inventory health. A method may include receiving an offer to purchase units of an inventory item via a purchasing channel for a purchase price per unit; determining a rate of sales demand of the item; and determining a breakeven holding time of existing units of the item, where a cost of holding a unit until the breakeven holding time equals, within an equality threshold, a difference between a sales channel value and the offer purchase price. The method may additionally include determining a healthy inventory level of the item that exceeds a target inventory level by a function of the sales demand rate and the breakeven holding time, and, if a current inventory level of the item exceeds the healthy level, declining to purchase units of said inventory item for the purchase price.

Method and system for analyzing inventory purchasing opportunities with respect to inventory health

A method and system for determining inventory health with respect to a disposition channel. A method may include specifying a target inventory level of an inventory item; determining a rate of sales demand of the item; and determining a breakeven holding time of units of the item in excess of the target level, where a cost of holding a unit until the breakeven holding time equals, within an equality threshold, a difference between a sales channel value and a disposition channel value for the item. The method may additionally include determining a healthy inventory level of the item that exceeds the target inventory level by the product of the sales demand rate and the breakeven holding time, and, if a current inventory level of the item exceeds the healthy level, disposing of excess units of the item via the disposition channel.
