Answering these 12 questions tell more about your supply chain performance than nearly all benchmarks and audits that the market has to offer. This test should take about 5 minutes of your time.
Can supply chain operate without Excel? Is ABC analysis regarded as obsolete? Is all relevant data documented by the supply chain teams? Do you record historical stock levels? Do supply chain teams monitor the quality of their data?

Thanks to the probabilistic forecasting engine that we released last year, our capacity to optimize supply chains has dramatically improved over the last couple of months. Through our growing experience, we have come to realize that there are 5 principles that drive the success of the supply chain initiatives undertaken by Lokad:
All possible futures must be considered; a probability for each possibility. All feasible decisions must considered; an economic score for each possibility.

The dashboards produced by Lokad are composite: they are built of tiles that can be rearranged as you see fit. We have many different tiles available: linechart, barchart, piechart, table, histogram, etc. This tile approach offers great flexibility when it comes to crafting a dashboard that contains the exact figures your company needs. Recently, we have introduced two extra tiles in order to help fine-tune your dashboards even further.
The Summary tile offers a compact approach for displaying KPIs (key performance indicators).

How long does it take to get started with Lokad? Answering this question is tough because often our answer is about 3 to 6 months. Hell, 6 months! How can your software be so clunky that it can take up to 6 months to get started? Well, our typical set-up phases can be broken down as follows:
90 to 180 days: preparing the data 3 to 30 days: configuring Lokad This shows that Lokad’s setup is actually lightweight.

Forecasting promotions is notoriously difficult. It involves data challenges, process challenges and optimization challenges. As promotions are present everywhere in the retail sector, they have been a long-term concern for Lokad.
However, while nearly every single retailer has its share of promotions, and while nearly every forecasting vendor claims to provide full support for handling promotions, the reality is that nearly all forecasting solutions out there are far from being satisfying in this regard.

Supply chains moved quite early on towards computer-based management systems. Yet, as a result, many large companies have decade-old supply chain systems which tend to be sluggish when it comes to crunching a lot of data. Certainly, tons of Big Data technologies are available nowadays, but companies are treading carefully. Many, if not most, of those Big Data companies are critically dependent on top-notch engineering talent to get their technologies working smoothly; and not all companies succeed, unlike Facebook, in rewriting layers of Big Data technologies for making them work.

Yes. To a noticeable extent. And I would never have ventured to put forward this opinion when founding Lokad nearly a decade ago.
By compilation I refer to the art of crafting compilers, that is, computer programs that translate source code into another language. Few people outside the ranks of programmers know what a compiler does, and few people within the ranks of programmers know how a compiler is designed. At first, compilation concerns appear distant (to say the least) to supply chain concerns.

The future is uncertain, and one of the best mathematical tools we have for coping with this fact is the distribution of probability. Lokad features both a probabilistic forecasting engine and an algebra of distributions. These two capabilities get along pretty well when it comes to dealing with complex, erratic and very uncertain supply chain situations. At their core, these capabilities rely enormously on processing distributions of probabilities. Yet, until recently, Lokad was lacking convenient ways to visualize these distributions.

The releases of Lokad are done on Tuesdays, and every Tuesday, we release a few more useful bits. Sometimes we release major components - like our latest probabilistic forecasting engine - but nearly every week comes with a few more features and enhancements. Software development at Lokad is very incremental.
A few weeks ago, we improved our line chart. So far, it was only possible to specify one color - the primary color - for the line chart, and then, if multiple lines were to be present, Envision was auto-picking one color for each line.

The future is uncertain. Yet, nearly all predictive supply chain solutions make the opposite assumption: they assume that their forecasts are correct, and hence roll out their simulations based on those forecasts. Implicitly, the future is assumed to be certain and complications ensue.
From a historical perspective, software engineers were not making those assumptions without a reason: a deterministic future was the only option that the early - and not so early - computers could process at best.

File formats are staggeringly diverse. At Lokad, our ambition is to support all the (reasonable) tabular file formats. We were already supporting CSV (comma-separated values) files with all their variants - which can involve varying separators or varying line returns.
However, tabular files can become very large, and in order to make the file transfer to Lokad faster, these files can be compressed. Lossless compression of flat text files works very well, frequently yielding a compression ratio below 10%, i.

A little over one year ago, we unveiled quantile grids as our 3.0 forecasting technology. More than ever, Lokad remains committed to delivering the best forecasts that technology can produce, and today, our 4th generation of forecasting technology, namely our probabilistic forecasting engine, is live and available in production for all clients. This new engine consists of a complete rewrite of our forecasting technology stack, and addresses many long-standing challenges that we were facing.

When data scientists work with Envision, our domain-specific language tailored for quantitative optimization for commerce, we want to ensure that they are as productive as possible. Indeed, data scientists don’t grow on trees, and when you happen to have one available, you want to make the most of his time.
A data analysis begins by loading input data, which happens to be stored as flat files within Lokad. Therefore, an Envision script always starts with a few statements such as:

Proofs of concept are one of the most frequent requests we get from our prospect clients looking to try out our supply chain optimization service. Yet, we frequently decline such requests; first because they hurt client’s company itself, and second because they also hurt Lokad in the process. Since POCs – or proofs-of-concept – are so widespread in B2B software, it is usually hard to grasp why they can be downright harmful in the specific case of quantitative supply chain optimization (1).

Under the supervision of Prof. Dr. Stefan Minner, Leander Zimmermann and Patrick Menzel are writing a thesis at the Technical University of Munich. The goal of this study is to compare inventory optimization software. Lokad did receive their questionnaire, and with the permission of the authors, we are publishing here both their questions and our answers.
1. When did you introduce your optimization software to the market?
Lokad was launched in 2008, but as a pure demand forecasting solution at the time.

The web was not really intended to transfer giganormous files. In order to do that, there are other (older) protocols like FTP (the File Transfer Protocol) or its secure alternative FTPS and SFTP. Lokad was already supporting many file receiving options, including web uploads. However, until today, our web uploads were restricted to files weighing less than 200MB.
Today, we have released a new version of our web upload features, and it’s now possible to upload arbitrarily large files through your favorite web browser into Lokad.

When it comes to supply chain optimization, it’s important to accommodate the challenges while minimizing the amount of reality distortion that get introduced in the process. The tools should embrace the challenge as it stands instead of distorting the challenge to make it fit within the tools.
Two years ago, we introduced Envision, a domain-specific language, precisely intended as a way to accommodate the incredibly diverse range of situations found in supply chain.

The technology of Lokad has evolved so much that people who have had the chance to trial Lokad even two years ago would barely recognize the app as it stands today.
The “old” Lokad was completely centered around our forecasting engine - i.e. what you can see as a forecasting project in your Lokad account today. As a result, our forecasting engine gradually gained tons of features not even remotely related to statistics.
