Alastri is pleased to announce the release of v21.2
v21.1 versions will only run on v2.0.77 of the Alastri Hub and higher. View the new Hub release notes here: 2.0.77 The new hub can be downloaded from the Alastri Server - https://licensing.alastri.com.au/Download/Latest
Starting with v21.2, the concept of Early Access has been retired. All users now have access to all versions - for assistance on which version to use, consult this guide: /wiki/spaces/DED/pages/27230462
If you work for a large company, consult your company’s central Alastri contact for when to switch versions.
Upgrading to v21.2 of ATS and APS may require updates to your scripts if you are coming from a version prior to 20.5. Consult your friendly Alastri Support team for assistance - it’s included as part of your subscription.

Truck Optimisation
Problem: In version 21.1 we introduced the Truck Dispatch system which was a significant improvement over the previous trucking system which mixed instantaneous logic with TUM logic. When using the Truck Dispatch mode, it was highlighted that it was very difficult to troubleshoot why the optimiser was doing certain things, i.e. – sending material to a stockpile despite the crusher being starved. This was a result of the schedule needing to complete two passes to assign the trucks. Other limitations existed around the period-based digger assignments.
Solution: In version 21.2, trucks have been included as part of the optimisation equation. Introducing the trucks into the objective function results in the truck allocation being fully optimised. The digger priority table in the calendar has been removed as cash flows dictate where trucks are assigned. The truck allocation is now determined by how much diggers are contributing to the maximisation of the objective function. In most situations, the highest cash flow will be to feed ore to the crusher. As a result, when a new steady state is created causing the optimisation to run, diggers which are sourcing crusher feed should be first in line to receive trucks.
Delay Sequence
Problem: It is common practice to model tramming delays for drills and in some cases diggers. The only way to achieve this in APS currently is to have multiple sequence bars containing one pattern with delay bars inserted between them. This process is rather inefficient, and users lose the ability to quickly draw their sequence in one go using the sequence painter. If during the schedule, a pattern is delayed, all of the delay sequence bars need to be repositioned which is a time-consuming task.
Solution: A new Sequence type has been developed called a ‘Delay Sequence’ which enables users to insert delays directly between blocks chosen in the block picker. The delays can be configured in the XXX which is found in the Sequence Painter UI or in the properties panel of the selected sequence.
The type of delay to be applied to the end of the record can be set by either clicking in the duration box next to the pattern name and selecting the delay from the list, or from the drop-down list in the multi-select input located down the bottom. Like the delay type, the delay duration can be entered directly in the duration box or in the delay length input located down the bottom. Delays can be inserted at the start of the sequence or at the end end of the sequence by using the two buttons located on the far left of the toolbar.
