Quality

MineMarket tracks the mass transferred as well as the quality of material through the supply chain. You can create samples for each transaction or movement to record the quality at that point of the supply chain.

However, the larger context of quality involves the specific specifications against which the quality should be measured. The specification defines the set of analytes to be measured for a transaction or movement. In addition, the specification allows for a comparison and tracking of the expected quality and actual quality. Each product has a set specification.

The various objects associated with quality are:

• Analyte—Type of quality measurements that can be recorded.
• Analyte group—Order-dependent grouping of analytes.
• Special sample—Quality samples that include analytes.
• Result type—Type of result and the confidence in the accuracy of the assessment, graded against other result types.
• Sampling template—Templates used to create sample templates for a material flow so that specific analytes can be measured across the material flow.
• Specification template—Generic specification definitions to list the acceptable ranges of analytes and the order in which they should display. Used wherever a specification must be made for a list of analytes (for example, creating product specifications).

Analytes and analyte groups can be used to specify the analytes in specification definition templates, products, brands, sampling templates, surveys and contributor groups.

Quality Assumptions for Transactions

When material is moved to a stockpile, the quality is not always known from samples. Assumptions can be made about the quality of the new location based on the history or ancestry of the material.

The base assumption for a product is used to determine the quality of all analytes in the destination stockpile after a transaction across the material flow has taken place, if the analyte is not specified individually for the material flow.

To override the base assumption for the product, an individual base assumption for an analyte can be specified for the material flow.
