Pallet Loading Problem - Algorithm / Container Loading Calculator

Description The tool is required to have the ability to calculate and optimize the quantity and type of containers and / or quantity and type of vehicles required for the load specified by the customer. This tool must be integrated with the platform developed and the results will be used to calculate the price. Reference [login to view URL] Type of Cargo: Containers Trucks Containers: The customer can specify the number of complete containers he wants to load, identifying the type of container, and the maximum weight of each container. The customer can specify the number of packing units, their weight, measurements and cost of the merchandise so that the tool optimizes and calculates the number of containers per type of container and number of vehicles per type of vehicle. Loose loaded: The customer can specify the number of complete vehicles he wants to load, identifying the type of vehicle, and the weight of the merchandise in each vehicle. The customer can specify the number of packing units, their weight, measurements and cost of the merchandise so that the tool optimizes and calculates the number of vehicles per type of vehicle. Packaging: The customer will decide what type of packaging he will use within these options: Bulk Boxes Packs / Bags BigBag Units Wooden boxes Drums / tanks Load specifications: The customer will specify for each unit of loading the long, width and height dimensions in cm, weight in kg, the value in $ of each packing unit and the number of packing units; for bulk only it will specify the total weight; each unit except boxes and units must preload standard dimensions. It can be added up to 20 different types of units according to the tool of [login to view URL] Load type: The customer will specify if the load will use pallet or not: in case he chooses the pallet, he must specify the dimensions and capacity of the pallet by preloading the dimensions of the standard pallet used in Colombia according to the tool [login to view URL] Type of calculation: The customer will specify whether he wants the tool to automatically calculate the type of container/vehicle or select it manually according to the tool [login to view URL] Containers’ options are: 20 feet 40 feet 40 feet High Cube Vehicles’ options are: "Turbo": Maximum gross weight of the load (4,5 tons) Maximum weight gross vehicle with load (9 tons) Length (4,80 mt) Width (2,25 mt) Height (2,20 mt) Volume (23,76 m³) "Sencillo": Maximum gross weight of the load (9 tons) Maximum weight gross vehicle with load (16 tons) Length (6,00 mt) Width (2,40 mt) Height (2,50 mt) Volume (36,00 m³) ....and / or others.... Cubage: The customer must specify the cubage options, whether the cargo can be positioned as standard, turned up or turned aside, and whether it can be stacked with load down or up. Calculation of cubage: The tool must calculate and optimize the quantity and type of containers / vehicles and showed for each type of container / vehicle the cubage render according to the tool [login to view URL] The application displays the final result how the goods are loaded within the container, how much space has been occupied by the goods and available space within container, how many container / vehicles do we need, and a step by step how we packed the goods. REQUIREMENTS • PHP • Javascript • HTML (Bootstrap) + CSS • Graphic library, for instance GDI • Algorithm to solve the pallet loading problem • Classes and Functions have to be well commented and easily understandable. • The tool should also be consultable by a webservice. Up to you is to define: • Parameters of inputs, outputs, required and allowed values. • Errors and exceptions handling • Safety management (how will the webservice be safely consultable)
