System and Method of Segmented Modelling for Campaign Planning in a Very Large-Scale Supply Chain Network

A method, comprising:

• providing a supply chain network comprising a robotic inventory system, wherein the robotic inventory system is configured to adjust inventory levels;
• interconnecting via a network a planner and the robotic inventory system;
• modeling, by the planner comprising a processor and a non-transitory computer-readable storage medium, the supply chain network over a planning horizon, the planning horizon comprising one or more time buckets;
• formulating, by the planner, a supply chain master planning problem comprising a hierarchy of objective functions and one or more constraints, wherein each objective function of the hierarchy of objective functions is expressed as a minimization;
• identifying, by the planner, one or more campaignable buffers and one or more campaignable resources;
• dividing, by the planner, the supply chain master planning problem into a first segment, a second segment comprising the one or more campaignable buffers and the one or more campaignable resources, and a third segment comprising one or more items and operations downstream of the one or more campaignable resources and the one or more campaignable buffers;
• modeling, by the planner, one or more campaign objective functions specific to a campaign planning solution;
• segmenting, by the planner, a campaign planning problem into three stages;
• solving, by the planner, a campaign planning problem of a first stage of the three stages to determine prioritized production demands on the one or more campaignable buffers;
• solving, by the planner, a campaign planning problem of a second stage of the three stages to determine a timing and a sequence for allocating the one or more campaignable resources;
• solving, by the planner, a campaign planning problem of a third stage of the three stages to determine a quantity of one or more products to produce on at least one of the one or more campaignable resources by solving the campaign planning problem of the second stage;
• and
• instructing, by the planner, the robotic inventory system to adjust inventory levels at various stocking points determined by the solution of the campaign planning problem of the third stage.

A non-transitory computer-readable medium embodied with software, the software when executed configured to:

• interconnect via a network, a supply chain network comprising a robotic inventory system and a planner, wherein the robotic inventory system is configured to adjust inventory levels and the planner comprises a processor and memory;
• model the supply chain network over a planning horizon, the planning horizon comprising one or more time buckets;
• formulate a supply chain master planning problem comprising a hierarchy of objective functions and one or more constraints, wherein each objective function of the hierarchy of objective functions is expressed as a minimization;
• identify one or more campaignable buffers and one or more campaignable resources;
• divide the supply chain master planning problem into a first segment, a second segment comprising the one or more campaignable buffers and the one or more campaignable resources, and a third segment comprising one or more items and operations downstream of the one or more campaignable resources and the one or more campaignable buffers;
• model one or more campaign objective functions specific to a campaign planning solution;
• segment a campaign planning problem into three stages;
• solve a campaign planning problem of a first stage of the three stages to determine prioritized production demands on the one or more campaignable buffers;
• solve a campaign planning problem of a second stage of the three stages to determine a timing and a sequence for allocating the one or more campaignable resources;
• solve a campaign planning problem of a third stage of the three stages to determine a quantity of one or more products to produce on at least one of the one or more campaignable resources by solving the campaign planning problem of the second stage;
• and
• instruct the robotic inventory system to adjust inventory levels at various stocking points determined by the solution of the campaign planning problem of the third stage.
