Manufacturing is the key player in applied intelligent configuration, but software businesses are catching up too. Factoring out dependencies between components (or classes, services etc.) to separate configuration issues from application logic, is a well-tried SW-variability principle likely to evolve further in the era of machine learning (ML).\u00a0 \u00a0<\/span><\/b>

<\/span><\/b>Dependency\u2026.\u00a0<\/span><\/b>
\u2026inversion, injection, \u201cintermediation\u201d (broker pattern, bus pattern), factoring-out (configuration-file pattern), etc; well-known SW architecture tasks. Some \u201ctricks of the trade\u201d in product configuration elsewhere turn out useful in IT as well and, judging from some recent papers, ML becomes augmentative for those.<\/span>

Intelligent configurators assist, or replace in part, a human role such as a technical salesperson. Which in turn implies a \u201ctranslation\u201d from a customer\u2019s wishlist to a matching selection of components and their configuration, without redesign. The result: a custom-fit product offer (sometimes even one-of-a-kind) without any new components. Quote-to-Order & Configur-to-order. The logic (figuratively \u201cgrammar rules\u201d of \u201ctranslation\u201d) is expressed in constraints, inclusion\/exclusion rules, and more recently even stored as relationships within a component cluster (\u201cpool\u201d) in a noSQL database like for example, Graph. On the product & product-data side, this implies quite a degree of architecture and modular design-to-configure.<\/span>

If you\u2019re looking for an insightful update on applied analytics, AI, and ML in cloud ERP, especially for automotive and manufacturing, make sure to read this Forbes article by Louis Columbus from July 2018.<\/span>

Component Configuration<\/b><\/span><\/p>\n

This is the simpler case where the customer knows which components in which configurations match the requirements (functional and nonfunctional). The customer has enough application-and-component knowledge to make a good \u201ctranslation\u201d upfront, from a wishlist to product-data compatible, along the lines of a Bill of materials. The configurator compares similar possible configurations, and also, checks that applicable rules and constraints are met; for example, doors must open and shut smoothly even when the selected interior extras are in place, or in SW, latency limits must be met even with all necessary firewalls in place.<\/span>
Especially in the software realm, this tends to underline structure.\u00a0\u00a0<\/span>

Functional Configuration<\/b><\/span><\/p>\n

This is the challenging case where it\u2019s up to the configurator and salesperson to figure out how the customer\u2019s wishlist (of both FR and NFR) maps onto components, parameters, and particular configurations. Here, the configurator contains both domain knowledge and application-and-component knowledge necessary for a sufficient translation. Knowledge-based configurators are quite good in this within well-defined domains, not least in manufacturing industries. Today, BI and CI (Customer Insight) also enable configurators to estimate customer preferences, so that they can suggest components more accurately.<\/span>

Especially in the software realm, this tends to underline behavior and functional requirements (from user stories, use cases, features, etc.)<\/span>

Machine Learning<\/b><\/span>
Sometimes, it\u2019s profitable, as a first choice, to \u201creplay\u201d configurations from recent similar orders (those with good margins and customer ratings), using simpler ML technologies such as Case Based Reasoning. If none of the orders fits, then we\u2019ve the current tradeoff between on one hand, ML from order statistics to fine-tune the configurator logic, and on the other hand, auditability, comprehensibility, predictability, traceability, V&V.<\/span>

A hybrid approach is ML (from past orders, plus corresponding lifecycle-history data) to fine-tune the rules and constraints of the configurator, making them accurate. That is, rules are still represented transparently, as rules, although ML gradually makes their conditionals smarter. Even in the \u201creplay\u201d order data, ML can improve classification of past orders into categories, to efficiently match particular customers\u2019 wishlists.<\/span>

Sub-symbolic \u201copaque\u201d logic from deep learning will cover more tasks than this, but we\u2019ll still need an add-on that will transform it \u201cback\u201d to something humans find transparent enough; visualization tools for decision trees or Graph databases are widely available, including open source (for a picture, see this post on noSQL and Panama Papers). Configurator logic and key PDM data are knowledge assets worth secrecy, for sure, but also worth thorough control and transparency to authorized roles.\u00a0 \u00a0 \u00a0 <\/span>\u00a0 \u00a0 \u00a0<\/span><\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n<\/span><\/span>\r\n
