Achieving — and maintaining — the competitive edge is imperative for manufacturers today, not just to stay a step ahead, but to survive. Success depends on operating lean and efficient. In this information age, this means harnessing all the tools available to improve precision and quality of production and manufacturing operations.

 

Newest and foremost among those tools is the manufacturing execution system, or MES. Described initially in the 1990s by AMR Research ( www.amrresearch.com ) as applications that occupied the space between business-level planning systems (such as enterprise resource planning systems, or ERPs) and traditional plant-level systems (such as batch control), MES products are helping manufacturers share information enterprise-wide, and streamline, optimize, and improve day-to-day plant operations.

 

The growth of MES installations and applications and their impact on the automation and control environment prompted Control Engineering and Reed Research Group ( www.reedbusiness.com ) to survey subscribers — for the first time — on their views and preferences about these products. Highlights of this recent email/online study follow, based on more than 100 responses.

 

A significant majority of respondents get data to MES applications and other systems through manual data entry, although custom code and OPC were also used by almost as many.

MES status report card

 

Ascertaining how and the extent to which MES is being applied in the plant, respondents indicated they were involved in specifying and purchasing such systems. More than three-quarters said they did so for process manufacturing applications, while almost a quarter said they used them in discrete manufacturing. Nearly 70% said they already have an MES in place; the remaining 31% said they were planning to purchase one.

 

In almost all cases (93%), the company IT team is or was involved in MES selection or implementation. In nearly a third of the cases (31%), IT was heavily involved, having the authority to recommend or reject a system. IT was moderately involved in the selection and implementation of 43% of the systems (provided technical guidance but was part of a larger decision-making team). Nearly a fifth of the respondents (19%) said IT was involved, but not heavily, in the process. Only 7% said IT was not involved in the effort, that the project was driven by operations or finance.

 

Off the shelf, home grown, hybrid

 

When asked about the configuration of their systems — in place and planned — slightly more than a third (35%) of the respondents said they were using an off-the-shelf system. Less than a fifth (17%) had a “home-grown” solution. Nearly half the respondents (48%) have systems that are hybrids of the two types. Answers to why they were purchasing or had implemented an MES application were varied. Most (89%) said they were seeking to improve productivity and throughput. Around 70% said they wanted to reduce costs, improve quality, and reduce errors. Almost half (46%) hoped to reduce scrap and rework. Many gave multiple answers.

 

Respondents were queried at length about system use patterns and preferences. More than two-thirds (69%) said they had integrated (39%) or planned to integrate (30%) their MES and ERP (enterprise resource planning) systems. Nearly three-fourths (73%) characterized the integration as “not easy,” the sum of 30% “not at all easy” and 43% “somewhat uneasy.” Virtually no respondents said the process was easy, although about a quarter (26%) selected “somewhat easy.”

 

When asked if they were using the MES to capture employee time-based data and machine-based data from the plant floor, most respondents (71%) said yes, they were now doing so or soon planned to do so. Queried further about the level of granularity at which they were capturing and analyzing data, more than half of that group (52%) selected “machine/process.” Other levels noted were plant (by 14%), cell (by 13%), line (by 10%), and multi-plant (by 8%).

 

MES benefits depend on how effectively data are captured and handled. A significant majority of respondents (57%) get data to MES applications and to other systems through manual data entry at least some of the time. Nearly half (48%) said they used custom code and almost as many (46%) use OPC. A sizable portion (36%) use middleware and nearly a fifth (19%) use XML schemas. (View the complete distribution in the accompanying bar chart.)

 

Information from MES applications is delivered in a variety of ways, according to respondents. More than half have a plant-floor HMI or dashboard (56%) and/or Internet-based (Web-browser) access (53%); 43% generate paper reports and almost a third (31%) use a proprietary network interface. When asked about using MES data for calculating overall equipment effectiveness (OEE) or developing other key performance indicators (KPIs), nearly all (84%) said they already were doing so (44%) or planning to do so (41%).

 

Another area of interest was how frequently information was extracted from an MES and for what purpose. More than half (52%) of the respondents said they leveraged data in real time to make adjustments of the plant floor. For 17%, data extraction was done once-a-shift to assess the performance of a specific line. Seven percent said they drew information once a day, and 9% said they pulled data weekly to compare performance again established goals. (The accompanying bar chart illustrates the frequency rates in more detail.)

 

 

Benefits, lessons, pitfalls

To help determine the impact of MES on manufacturing operations, respondents were asked to share information about their investments in MES and the return on those investments. Although respondents were somewhat hesitant to cite clearly demonstrable returns on MES investments, a significant number admitted their systems had led to improved efficiency, and planned to up — or maintain at least — their MES investments.

 

Looking at this concept more closely: only 30% of respondents said they measured a demonstrable return on investment (ROI) on MES. Some 18% said they had experienced no measurable ROI, 32% said they were not measuring or calculating these figures, and 20% were unsure they had measured a demonstrable return. However, more than half (57%) said the systems improved efficiency, quality, or throughput. In addition, more than half (55%) anticipate their MES investment would increase in the next 12 to 24 months; 39% said they would spend about the same. Only a few (6%) expected to see a decrease in MES investments.

 

The positive outlook reflected in these statistics is supported by comments from respondents; many took time to offer advice to those just beginning with MES implementation. Many suggestions apply to all projects: “Be sure to define your goals.” “Remember that details are important.” “Develop a well-defined roadmap.” “Involve all stake-holders.” “Keep in mind future technological evolution.” “Focus on actual needs, not what someone else thinks you need.” “Build a team to manage the endeavor.”

 

But other comments targeted the MES more specifically. Said one respondent, “Develop a realistic, long-term strategy that focuses on collecting only data that have value. Put a sound infrastructure in place and work closely with those on the plant floor who'll be providing input to the data stream.” Offered another, “Create a team consisting of IT, controls, accounting, and production, with at least one senior manager closely involved.” Another respondent noted that it was critical that business customers are thoroughly engaged through the requirements gathering and design process. “The correct design will provide valuable and useful information to the business,” he pointed out, “instead of a lot of non-useful information.”

 

Perhaps most emphatic was the respondent who said simply, about MES: “Do it now! The payback is there. Working with IT is a must, but operations must keep control.”
