PLM Formulations for Chemicals

The roots of product lifecycle management and how PLM can help chemical companies today

Product Lifecycle Management (PLM) originated in the automotive industry, and as a breed of IT application it is still mainly associated with discrete manufacturing. Having started with the scope of product data management for the development phase of a product lifecycle, the reach of the technology has evolved to cover the full product lifecycle — and close the loop by supporting the exploitation of field experience to drive front end innovation (for example, Oracle seeks to reinforce this by referring to ‘Product Value Chain Management’).

The PLM technologies designed for discrete manufacturing industries deliver enormous benefit in product development scenarios involving high numbers of parts with their relationships defined by a well-structured bill of material (BOM) and especially where there are a variety of different individuals/organizations contributing to the development, manufacture, sale and support of the product. As a result, the PLM market has grown to approaching $3 billion in software revenues and much larger if you count the services and support ecosystem. Having said that, although progress in recent years has been substantial, the adoption of PLM in chemicals has been rather more tentative — with good reason.

PLM IN THE CHEMICALS INDUSTRY
PLM’s initial foray into the process industries came from several directions. First, there were the understandable efforts to bend, twist and augment the functionality of the systems that had proved highly capable for discrete manufacturing. At a high enough level, this would be fine — the chemicals industry formulation simply replacing the automotive BOM (although while a car has more than 30,000 components parts, it’s unlikely that a chemical formulation will have 30,000 ingredients). And after all, PLM is brilliant information management technology with workflow and information flow capabilities built in. However, the requirements of the chemicals industry have proved quite a barrier to moving discrete manufacturing technologies across.

Contemporary discrete-manufacturing PLM technologies knit together the data from the various applications used in product development — CAD, CAE, CAM. Some of the top PLM vendors (Autodesk, Dassault, PTC, Siemens) are companies that provide those ‘data creation’ solutions too. There is a “kind of” equivalence in the chemicals industry in terms of the range of applications involved in product development (for example, tools to support the development of formulations, lab data management, DoE and so on) but there are key differences as far as achieving the same breadth of coverage with PLM.

Chief among these are the fact that development of formulae for chemicals products involves a variety of scientific processes and the product data includes production process parameters; packaging is often an integral part of the ‘product’ and must draw on all manner of product attributes; and the product-related information to be managed involves a combination of structured and unstructured data that is a real challenge for traditional discrete market PLM technologies.

PLM offered chemical producers another solution initially, an extension of the business (ERP) system vendors’ product information management capabilities. However, the same limitations still apply and the approach seemed to embody a tacit acceptance of the limitations of PLM —given the goal to manage product information alongside other specialist applications — while providing an overall glue for the application set as well as an index to all the data wherever it’s held. Vendors offering applications for specific aspects of the chemicals product lifecycle created a third approach which sought to build these out to provide broader workflow and information management capabilities.

However, chemical companies did not want to wait until there was a total all-embracing solution for chemicals (indeed, they would still be waiting!). As a result, it’s perhaps most appropriate to talk about the product lifecycle information management picture in chemicals today in terms of PLM “environments” rather than “systems” because, even within individual companies, achieving a comprehensive PLM capability has usually involved phased deployment of different applications for specific areas of the product lifecycle and a build-up of integrations to knit them together.

What can PLM do for chemicals companies today? For the discrete manufacturers, the classic PLM benefits include:

• Integration of all ‘data creation’ systems leading to a reduction in the complexity of managing product development processes through effective information sharing and collaboration;
• Controlled sharing of information throughout the value chain – integration of information across the product development, manufacturing, supply, support and retirement processes;
• Better decisions on optimization of the innovation project portfolio – including information drawn from field performance of products (maintenance systems, supply chain systems) and information held in the ERP system (supplier, cost data); and of course,
• Ease of collating and organizing information associated with industry regulations.

The result is more innovative, higher quality products brought to market more quickly and supported more effectively. So, given the hurdles that we have identified above, can PLM deliver these huge benefits for the chemicals industry? While there are several aspects that are important to competitive position and for which individual companies can develop their own strategies, there is one, compliance with industry regulations, that is not an option, it’s a “table stake.” The data needed to meet regulatory requirements varies from region to region or even from one part of a country to another and both the descriptions of the requirements and the information to be supplied comes in a variety of formats. So the document management capabilities of the PLM solution must be highly flexible in that respect alone. In addition, compliance must be monitored throughout the product lifecycle, all the way for initial development to retirement, given that regulations change all the time. A good example of the regulatory demands on the industry is the REACH (Registration, Evaluation, Authorization and Registration of Chemicals) safety standard that requires manufacturers and importers in Europe to register chemicals of which more than one tonne are used annually by supplying information such as chemical formulations, uses, volumes used and safety test results.
