Peripass uses different concepts to model logistics flows in the yard. Some concepts describe who is entering the site, others describe what operational work needs to be done, and others describe how references or assets are handled.

This article explains how the following concepts fit together:

Peripass models a logistics visit in different layers. Each layer answers a different question:

The highest level is the driver.

In Peripass, a driver can be represented by a Certified Person. This allows the platform to recognise the person and reuse trusted identity or certification data during the logistics flow.

A Certified Person is therefore linked to the person performing the transport, not directly to a specific order or reference.

A transport represents a group of related operations performed by the same truck or driver visit.

In Peripass, this is supported through Combined Transports. A Combined Transport groups multiple visitors together by using a shared grouping number.

This is useful when one truck visit contains multiple operational flows, for example:

The operation is the level where most operational tracking happens.

In Peripass, an operation is represented by a visitor. This is the level used to track:

A visitor can contain one or multiple order references, depending on the logistics flow.

Asset Management defines whether the driver stays with the truck during the operation, or whether a trailer is dropped off or picked up.

This is what we call the operation type. Because this describes how the operation is executed, the operation type belongs to the visitor / operation level.

Examples:

The lowest level is the order or reference.

Multiple order references can be part of one operation. For example, a visitor may refer to multiple references that will all be loaded at the same dock. In that case, the operation is still tracked as one visitor in Peripass, even though multiple references are involved.

A simple visitor being represented by a single reference.

The driver is identified as a Certified Person and has one operation to execute: picking up a trailer that has been loaded for a dedicated reference.

The driver needs to execute two operations that are grouped under one visit number.

The driver has:

The trailer being picked up may itself contain multiple delivery numbers. These delivery numbers are handled as multi-references within the pick-up operation.

There are two exceptional operation types where two asset movements are bundled into one operation (visitor).

This is technically a combined flow:

However, the driver often does not have a reference for the empty trailer being picked up. For that reason, the flow is bundled into one operation and linked to the drop-off visitor, which does have a reference.

This works in the same way, but in the opposite direction:

Multiple Check-in is a different concept.

With a Combined Transport, one truck or driver visit can contain multiple visitors or references.

With Multiple Check-in, the opposite happens: there is one reference, but that reference can be used by multiple drivers or trucks within a specific period.

This is useful when one order, contract, or reference needs to be executed across multiple physical visits.
