Create a Rectangular Warehouse Layout from COPRAS Locations

Description

This function generates a rectangular warehouse layout matrix based on COPRAS-assigned locations, given the warehouse dimensions.

Usage

rectangular_warehouse_from_copras_locations(
  locations,
  warehouse_width,
  warehouse_height
)

Arguments

locations	A numeric vector representing the COPRAS-assigned locations of items in the warehouse.
warehouse_width	An integer specifying the width of the warehouse.
warehouse_height	An integer specifying the height of the warehouse.

Details

The function maps the given COPRAS-assigned item locations to a rectangular warehouse layout. The x and y coordinates are calculated based on the warehouse dimensions and adjusted for the warehouse structure. Additional rows are added for boundary positions at the top and bottom of the warehouse.

The resulting matrix contains the following columns: - 'x': The x-coordinate (column) of the warehouse. - 'y': The y-coordinate (row) of the warehouse.

The matrix is sorted by x and y coordinates and ensures unique rows in the layout.

Value

A matrix representing the rectangular warehouse layout. Each row corresponds to a coordinate in the warehouse.
