Material

Tracking material

A Tracking material is an entity that models a physical amount of material at a specific process location. The tracking material is the representation of a limited amount of mass or discrete unit of material with related information in the Apis Click&Trace database and the tracker application.

TraMaID

The tracking material has a unique database identifier called the TraMaID. The TraMaID is a database generated serial number of all the Tracking materials generated in the database.

Amount

The numeric Amount property of a tracking material describes the physical amount of material represented by the tracking material entity. The amount property is nonzero when the actual tracking material represents a physical material that currently is located at the position indicated by the tracking material. When the physical material moves from this location, the amount property is set to zero.

TraMaQualityCode

The data quality of the tracking material entity is defined by the TraMaQualityCode of the tracking material.

Genealogy

Genealogy is a term that describes relations between ancestors and descendants (parents and children) in large hierarchies. In the case of tracking the genealogy concept covers the relation between Tracking materials, i.e. what parent material a specific material is built up of, and how the material has moved through the process.

Material lot

A Material Lot (ML) is a virtual model of a discrete material that moves in the process topology. The ML describes a chain of single-ancestor, single-descendant tracking materials in the Genealogy. The Material Lot is actually a collection of TrackingMaterials that form the lifecycle of a discrete material entity. The Material lot concept is used with discrete tracking. When concept is used, every TrackingMaterial is related to a Material Lot and given a sequence number inside the material lot. This concept has great advantages in terms of reporting. The data quality of the material lot entity is defined by the QualityCode of the material lot.

Individual probability

The individual probability is a property of the Material lot. The individual probability is a concept that describes the probability that a material lot is exactly identified, i.e. the probability that the material mapping in the Apis Click&Trace database is correct and that the material lot references the correct physical lot. By default the individual probability is 1.0. When a new probability is assigned, the current probability of the material lot is multiplied by the new probability. New probabilities should be assigned wherever there is uncertainty in the material identification, and the resulting individual probability will be the product of all the uncertainties.

Material definition

The material definition is a way to classify different types of material by physical properties. Examples of Material Definitions may be liquid metal, gas, water and meat. The Material definition does not specify what type of gas, type of meat, the vendor of the meat and so on, which is the purpose of the article. A material definition can be considered as “the type of material that can flow in this pipe”, “the type of material that is produced by this machine” or “the type of material that can be stored in this container”. 

Material Lot definition

The Material Lot definition is used to distinguish several types of discrete traceable units in the production. A material lot is a non dividable and non mixable unit of material, and the purpose of the material lot definition is to model several different types of non dividable and non mixable material units.
