Maestro Workflows in Tryton

This article is part of a series on the Tryton framework, and complements the Maestro project on GitHub. This article explores a number of Maestro workflows using Tryton.

This article is a work in process.

Background

The Swift Construction Company (SCC) manufactures a radio receiver called an Aircraft Wireless. The SCC buys assembled electronics circuit boards (part number 20000003) in lots of 5 from Trilogy-Net. The circuit boards are used in the assembly of Aircraft Wireless units (part number 10000003). When circuit boards arrive from Trilogy-Net at the SCC, they are inspected, identified with a serial number and stocked in inventory. The SCC has a number of customers for Aircraft Wireless units, including B&E Submarines who purchased an Aircraft Wireless system to evaluate.

Workflows

Serialized Stock Purchased by a Customer

This workflow explores serialized stock in the context of a customer purchase. B&E Submarines desires to purchase a spare parts kit for the Aircraft Wireless unit they previously purchased. A serialized circuit board is used in the assembly of the spare parts kit (preferably a phantom-type BoM to make the parts in it visible), which is then sold and delivered to B&E.

Sometime later, Ed Bentley calls from B&E. He says he found a circuit board, but he doesn’t know if it is the circuit board from the spares kit. Ed is not sure, but he thinks the original board might have failed and he swapped it with the one from the spare parts kit. Ed wants to know if the serial number on the board is the same as the board shipped in the spare parts kit he bought.

Serialized Stock Consumed by a Project

Explore serial numbers in the context of a project. B&E Submarines plans to upgrade 5 of their submarines with Aircraft Wireless systems. A contract is negotiated between the SCC and B&E, and the SCC initiates a Project to capture all related activity (of which the physical receiver units are only one portion). Complete radio receivers PN 10000003 are manufactured, each with its own serial number, traceable to the serialized electronics circuit board within. The completed radio receivers are sold and delivered to B&E as part of the overall project.

Sometime later, Ed Bentley calls from B&E. He has a circuit board in his hand again, and wants to know where the serial number came from. Ed asks if the circuit board was from one of the 5 receivers delivered as part of the upgrade project.

Create, sell, ship, and return a field spares kit

  • Create manufacturing order
  • Issue material to order (serialized PCA)
  • Deliver order to customer
  • Return order from customer
  • Return material to stock (serialized PCA)
