Systems and methods for controlling and optimizing order fulfillment from a network of fulfillment centers

A computer-implemented method of controlling order fulfillment from a network of fulfillment centers, the method comprising:

• receiving, at a processor, a first batch of orders defined by either a threshold number of orders received or a predetermined period of time after a first order is received;
• assembling, at the processor, a model based on the first batch of orders, the model comprising a plurality of modules, wherein each module in the model includes algorithms having fulfilment logic and variables based on constraints, external factors and routing objectives of the network related to the first batch of orders, wherein the assembling causes the model to:
• (1) generate an initial allocation of the first batch of orders between fulfillment centers of the network of fulfillment centers that is within a predetermined volume, and (2) apply a reallocation function to direct a change to the initial allocation of the first batch of orders among the fulfillment centers to keep the network of fulfillment centers within the predetermined volume;
• receiving, at the processor, a model output for the model comprising an allocated solution for each of the variables that is resolvable to a shipping outcome for each order in the first batch of orders;
• performing, at the processor, an optimization on the model output to obtain optimal routes for each of the first batch of orders based on the constraints;
• performing, at the processor, post-processing on the optimal routes to generate fulfillment data comprising fulfillment instruction data for filling complete order from the first batch of orders, the fulfillment instruction data including:
• identifying product, quantity, packaging instructions, and shipping instructions;
• displaying the fulfilment logic and the variables for the first batch of orders, in a graphical user interface;
• displaying one or more affordances to adjust the fulfillment logic or the variable;
• in response to receiving a user input to select the one or more affordances, applying a pre-processing algorithm to adjust at least one of the variables based on the user input;
• based on the adjusted at least one of the variables, repeating, assembling the model, receiving the model output for the model, and causing retransmission of the fulfillment data, based on the user input;
• and
• transmitting, by the processor, the fulfillment data to each fulfillment center to fill the complete order from the first batch of orders.
