Stockyard Configuration
A stockyard is a location that is used to store bulk material prior to despatching. A stockyard can have multiple stock rows, each of which can contain multiple stockpiles. Additional detail can be recorded about the position of stockpiles within stock rows, including defining metre marks and dead zones.
The stockyard stores the bulk material in First-in-first-out (FIFO) Stockpiles, Last-in-first-out (LIFO) Stockpiles or Weighted-average-grade (WAG) Stockpiles by product, held within the geographical constraints of a stock row. A stockpile is a physical grouping of bulk material, but can be broken up into smaller piles (represented via metre marks). This is done either if it is commercially beneficial, or just not physically possible to keep the stockpile in a single physical pile. The allocation of space that these smaller piles consume is represented by start and end metre marks for each specified stock row.
Stockyard Configuration
When a stockyard is created, no viewing settings or report templates, stock rows, dead zones, stock row joins or stockpiles are defined for it. The stockyard must be first configured before it is used.
Stockyards are configured to contain multiple stock rows which are geographically positioned within the stockyard. Stock rows can contain dead zones in which no stockpiles can be placed.
Stock row joins can be configured to allow a stockpile to physically sit across multiple stock rows. Joining stockpiles in stockyards is constrained by configured rules. The rules are a simulation of the physical constraints that exist in the stockyard, for example, a concrete barrier preventing joins between particular stock rows.
The configured stockyard can be viewed by timeline or from a bird's eye view.
Timeline View
A timeline view of a stockyard displays the stockpiles' occupation of physical space via the geographical length versus a date range. The representation of the stockyard assumes that each stock row has a fixed width, and thus is omitted. The timeline view shows the stock rows' physical length via a vertical graduation scale on the left and the horizontal date range via a graduation scale on the top. The timeline start and the number of days at the top of the screen control the date range display. The stockyard view settings defined by the stockyard configuration control the gap size between the stock rows, and whether stockpile names or stock row names display, and whether stock row names display horizontally or rotated vertically.
The timeline view display allows for the editing of each stockpile, its meterage or joins. The timeline view can zoom to fit the view into the screen, and you can copy the current display view to the clipboard, save the current display view to file as a bit-map file, print and print preview the current display view.
Bird's Eye View
A bird's eye view of a stockyard shows the physical layout of the stockpiles within the stockyard, on a given snapshot date. The bird's eye view settings defined by the stockyard configuration control whether tonnage, stockpile age, product, metre marks and analyte quality details display, whether this text displayed is trimmed to the meterage of the stockpile, the height of each stock row, the time of day at which the data is taken on the snapshot date, and whether joint stockpiles display as joined.
The bird's eye view can zoom to fit the view to the screen, and you can copy the current display view to the clipboard, save the current display view to file as a bit-map file, print and print preview the current display view.
Stockyard Breakdown
The breakdown shows the location, product and age of the small piles (defined by metre marks) of the stockpiles in the stockyard, and the total aggregated tonnage of the stockpile.
Note that the tonnage is not the tonnage of the individual metre marks but of the entire stockpile.
