To help manage, track, and reserve equipment effectively, our system organizes everything into a clear four-tier hierarchy. This structure ensures you always know what class of machinery is available, which model best fits the job specs, and exactly which physical asset is heading to the field.
Category (High-Level Classification)
- What it is: The highest organizational grouping used to separate completely different operational divisions (e.g., Excavation, Aerial Lifts, Power Generation).
- Necessity: Optional but highly recommended. You do not strictly need both Categories and Product Groups to run the system, but you must use at least one of the two to keep your fleet structurally organized.
Product Group (Size & Capacity Class)
- What it is: A subdivision within a category that groups machinery by its weight class, size, or power capacity (e.g., 25k lbs Excavators vs. 35k lbs Excavators).
- Necessity: Optional but highly recommended. This works alongside Categories to help users or clients filter directly to the specific capability scale they need. Remember: your system must utilize at least a Category, a Product Group, or both to function cleanly.
Product (Manufacturer & Model)
- What it is: The generic template representing a specific manufacturer make and model (e.g., Komatsu PC88MR-11 or Cat 315 GC). It houses all the permanent engineering specs, dimensions, and manuals.
- Necessity: Mandatory. Every system setup requires a Product profile. However, you cannot directly deploy or rent out a generic "Product"—it must contain active physical inventory.
Inventory (The Serialized Asset or Bulk Count)
- What it is: The actual, tangible machine parked in the equipment yard. Each individual inventory piece is a serialized item tied directly to its parent manufacturer and model.
-
Necessity: Mandatory. A product profile is just an empty placeholder without it. Each unique physical unit has its own dedicated Serial Number (e.g.,
KM-PC88-F849201) to track its lifetime hours, lifecycle history, and active field assignments.
Think of the Product as a book title (like 'The Great Gatsby') and the Inventory as the physical copies on the bookshelf. When you want to buy or rent the book, you don't take the abstract concept of the title home you pick up a physical copy with a specific barcode. If you have two identical Komatsu PC88MR-11 excavators in your yard, they share the exact same Product profile, but they are two completely separate Inventory assets with different serial numbers, lifetimes, and rental schedules.
