Organizing with ISA88
The history and basic details of batch methods and the ISA-88 standard are detailed in the online version of this classic article, "Organizing batch process control" by Bill Hawkins, published in the May/June 2012 issue of InTech. It covers physical models, control functions and recipes, and includes many of the batch field's useful flowcharts.

Basic data analytics
This online article, "Understanding the basics of batch process data analytics" by Lennart Eriksson, senior lecturer and principal data scientist at Sartorius Stedim Data Analytics, provides a concise explanation about how to process and examine data generated by a batch system. It focuses on biopharma applications, but the principles it brings up are useful for understanding information from many types of batch applications. It covers monitoring, modeling outputs and processes and statistical process control (SPC), and even has a webinar video at the end.

Small batch adventures
This 45-minute, "Adventures in Small Batch Manufacturing" by Danaca Jordan, first protégée of the ISA Mentor Program, provides an ISA Update, her experience moving from giant complex to a small plant and key plant problems she solved. The problems provide lessons on the use of anti-reset windup limits, override control, isolation valves, smart alarms, mass flow meters and the enforcement of low flow limits.

Continuous can use ISA-88
Because a continuous process is just a batch process with no traditionally defined endpoint, many of the useful principles in the ISA-88 standard can be applied to continuous processes as well. This concept was detailed awhile back by former Control senior technical editor Dan Hebert in his column, "ISA-88 works on continuous processes too."

Challenges, opportunities video
This 70-minute video, “Batch process control—unique challenges and opportunities” by Greg McMillan, Control Talk columnist, and presented by the ISA, explores how manufacturers are using modern process controls to maintain quality. McMillan talk about analyzing batch data, elevating the role of the operator, tuning key control loops, and setting up simple control strategies to optimize batch operations. There’s also an extensive list of best practices.
