Differentiable  programming to optimize over large scale relational data

Differentiable programming to optimize over large scale relational data

Paul Peseux's PhD research on differentiating relational queries - another under-researched area of supply chain - introduced TOTAL JOIN operator, Polystar and a mini-language ADSL to differentiate relational queries, all of which Lokad integrated into its DSL Envision as part of autodiff for optimizing daily inventory decision-making.

RFI, RFP and RFQ madness in supply chain

Over the years, Lokad has gained some notoriety, and we have earned the privilege of being part of an increasingly large number of RFI (request for information), RFP (request for proposal) and RFP (request for quote) related to supply chain optimization.

The maintenance of the optimization

Lokad offers a flat monthly fee for software and expert services, ensuring optimal supply chain performance. Traditional optimization software fails due to inadequate maintenance. Lokad's supply chain scientists maintain automation, requiring ongoing engineering resources to prevent reverting to inefficient spreadsheet management.

The role of IT

In many, probably most, large companies operating a supply chain, the IT department has years of backlog. The backlog is made of a myriad of glitches, inconsistencies, or fragilities that could be fixed but aren’t. Besides creating vast bureaucratic overheads, this endless series of pointless annoyances demotivates everyone.

Supplier Analysis through Envision - Workshop #1

Lokad launches its first Envision Workshop, teaching students (and supply chain specialists) how to analyze retail suppliers using Lokad's probabilistic, risk management perspective.

Pitfalls of supply chain for aeronautics

Aeronautics companies are fundamentally risk adverse – for very good reasons – and this reflects in the management of the companies’ activity in every area. However, this mentality can be a hindrance when it comes to supply chain, as avoiding risk and not integrating the very concept of risk at the heart of the supply chain means losing sight of what you are optimizing.

Let’s try Lokad

The engineering teams at Lokad have spent the last decade refining Envision, a specialized programming language dedicated to the predictive optimization of supply chains. As it turns out, most supply chain optimization challenges are, well, weird (for lack of a better word) and mainstream software technologies fall flat on their faces when confronted with such challenges.

LokadTV reaches 6000 subscribers

Almost exactly 18 months ago, I wrote a post to celebrate passing 3,000 subscribers on LokadTV. That post, in fact, was written almost 18 months after we celebrated passing 1,000 subscribers. Curiously enough, we passed 1000 subscribers about 18 months after we began actively promoting the channel.
