1. A computer system, comprising:
a database including information regarding a current stock of each of one or more items in each of a plurality of locations, historical data regarding a rate of decrease of a stock of each of the items in each of the plurality of locations, and historical data regarding replenishments of a stock of each of the items in each of the plurality of locations; a historical data analysis module, wherein the historical data analysis module is configured to determine average values and deviation values for the rate of decrease of the stock of each of the items in each of the plurality of locations and average values and deviation values for replenishment durations of the stock of each of the items in each of the plurality of locations; a reallocation scheduling module, the reallocation scheduling module configured to: obtain an objective function including one or more integer-valued decision variables, a first decision variable indicating a quantity of each of the one or more items to be transported between each of the plurality of locations, wherein one or more terms of the objective function include the first decision variable, the current stock of one or more items in the plurality of locations, and the average values and deviation values of the rate of decrease of the stock of the items in each of the plurality of locations and replenishment durations of the stock of each of the items in each of the plurality of locations, and wherein the objective function is a quadratic function with respect to the one or more decision variables; obtain one or more constraints, wherein the one or more constraints are linear with respect to the one or more decision variables; and automatically determine a proposed reallocation scheme for each of the items between the plurality of locations based on the objective function, wherein determining the reallocation scheme includes finding values of one or more decision variables that optimize the objective function while obeying the one or more constraints, wherein determining a proposed reallocation scheme includes solving an integer quadratic programming problem. |
