Large Scale Parametric Value Stream Model of BOXARR
Updated: Jun 3
Modern aerospace production systems and their supply chains are notoriously complex, global, and interwoven. The same can be said for many other sectors with highly engineered products. This is compounded by the trend to dual source, assemble at multiple sites, for multiple customers, and cope with rate increases year on year.
In response to this, and inspired by the challenges across all BOXARR’s industrial customers, BOXARR’s Chief Solutions Officer, Ian Poccachard, has developed the Large Scale Parametric Value Stream Model application of BOXARR, and commented:
"Thanks to our Solutions Engineer, Romain Roques’ tenacity, our clients’ enthusiastic participation, and our Chief Architect, Steve Jonik’s technical leadership, we have been able to reach another significant advancement of the BOXARR platform."
The screenshots in this article illustrate several views of a large-scale parametric value stream model application in BOXARR.

The model is built automatically from ERP and other data or can be developed collaboratively by hand. It’s flexible, scales, is economic, and powerful, letting your organisation understand and optimise its production system, and its supply chain together. It also helps you operate the production system with greater understanding so that everyone understands where the risks, opportunities, and impacts are. The product structure runs through the model, but so do the other dimensions of organisation, commodity group, geography, and others (dimensions are configurable).

The model integrates the value stream map, suppliers, internal plants, your customers, their locations, transport hubs, parts produced, their cost, cycle times, and transport routings. It calculates inventory on the fly (work in progress, expedition and reception stock, and in-transport stock). As rates, work-share, and other parameters are adjusted, the cost, load, and flow attributes on each node in the value stream are recalculated and can be compared with, for example, capacity. Mass and volumes are also recalculated, which in turn drives the transport cost model simultaneously with the other cost, inventory, and critical path calculations. The transport itself can be calculated based on % routine and % critical. Price grids can be loaded.c
The user can easily create scenarios, save them, apply them as layers, and then revert to the master model or merge in changes. Complex changes to the topology are handled with sophisticated copy and paste capabilities that are unparalleled, for example, to create duplicate sources, or simulate large work transfers. Transport and other flows are reconnected with ease.

With BOXARR you finally have the ability to economically do expanded supply chain design, optimisation, and operations in a visually compelling quantitative tool. Scenarios can be played, and the model immediately recalculates itself!
You can trade cost, lead-time, cash & inventory, risk, and other characteristics. This lets you prioritise investment and effort, make smarter purchasing decisions, release cash, and will let you avoid costly mistakes.
