  • System Configuration Management and Version Control in an FDA Regulated Environment

    Managing the genealogy of database configuration and its life cycle is critical to following 21 CFR Part 11. In addition to recipes and equipment model configurations, phase logic and control strategies residing in automated control systems are an integral part of automated batch execution. Typical configuration management systems do not provide the capability to implement and guarantee a standard development procedure for the database configuration. With a set of enforced qualification states and GAMPbased transitions, a strategy that has been properly tested and approved with signatures can be installed on a process system. For control systems operating in validated environments, this procedure is paramount. This paper explores the life cycle management requirements for batch phase logic and control strategies executing in a validated environment.

  • Targeting Batch Outcome using Predictive Control

    The paper will present a new methodology for using predictive control to improve batch process outcomes. Predictive control refers to a situation in which data collected during the execution of earlier process stages are used to retarget controllable variables during later process stages. Improvement is measured either by increasing output yield or by shifting the distribution of product outputs towards higher bin values, thereby increasing the value of a given output quantity. The technology includes a graphical method of presenting the logical flow of causality and functionality along a process. The paper describes how this methodology has been used in order to improve production outcomes in a batchbased system. The first part of the paper will present the technology, its pros and cons relatively to the traditional S88 without predictive control, and how the adaptive system is integrated within control systems. The second part of the paper will present results from a specific case study in which this technology has been implemented.

  • Using S88 Batch Techniques to Manage and Control Continuous Processes

    Have you ever thought of using batch sequencing and S88 recipe management techniques to control a continuous process? This paper will discuss the great similarities and subtle differences found in such applications. At Procter & Gamble we have successfully created several such “hybrid” process control applications. The results of these adventures greatly exceeded expectations. These systems benefited from an adaptation of the modular approach described in the S88.00.01 standard with some significant differences in the states of their Equipment Modules and Phases. The necessary modifications will be presented in detail.

  • Batch Control Analysis

    Batch control analysis is one of steps in the design of plants executing batch process - an S88-based analysis of batch process from the control point of view. It is between the conceptual design of the batch process (PFD or P&I) and the start of the design of the control system (design of instrumentation, control hardware and software). Its objective is to fill the gap almost always found between the formulation of requirements and the specification of the actual implementation. It transforms user requirements into “process-based” detailed functional requirements. It has several advantages if these problems are handled, not by software engineers, rather by batch control analysts who are closer to the plant and know the process better.

  • Batch Control Systems Market and User Requirements

    Standards for batch control systems continue to be developed and incorporated into many current and new automation products. This effort is having significant impact on the increased growth of the global batch control systems market and the automation architecture of the next generation of process control systems. This paper will include current market sales, forecasts, and strategic issues involved in continuation of this growth. It also will include a discussion of additional user requirements obtained from a survey of users in the food, beverage, pharmaceutical, and chemical industries. It will offer recommendations to address these issues, as highlighted in ARC studies, "Batch Control Systems Market Study 2001" and "Batch Control Systems Market Study 2002." The papers also will address how batch standards, traceability, event management, and change control will become core functions “designed into” future automation systems architectures rather than incomplete add on functions to current systems.

  • Batch Modeling in Pharma Industry: The Role of the Engineering Company

    The S88.01 rule is today a well accepted standard all over the world: all qualified engineers involved in the design of a batch control system are getting familiar with the terminology and models therein described. The focus is now on the implementation. As a matter of fact, the S88.01 standard is not a prescriptive guideline. This means that engineers must define, for each project, which documents are to be produced, by whom and with which formalisms.

  • "Collaborate-Breakthrough-Profit:" A Myth, Minefield or Treasure Chest?

    The objective of this paper is to provide an outlook on emerging Collaborative Production Management (CPM) tools. It will discuss these CPM tools in relation to material transfers (ingredient addition) in Batch manufacturing. Illustrating what collaborative initiatives these tools are likely to support, why they are required and how they may be deployed. The concept of collaborating is an old concept, but Collaborative Production Management, and the notion of CPM tools is a relatively new manufacturing trend. One that has been revitalized by the internet and the advent of more open manufacturing systems. Today global measurement and control suppliers find they are being pushed hard by manufacturers to increase their development momentum in this emerging area of “collaborative production management tools”.

  • Exception Handling for Optimal Batch Production

    This paper supports the application of an “Intelligent” exception handling strategy, which helps to provide maximum business benefit and optimum batch production. Incorrect or incomplete design of the exception handling philosophy for a batch control system can have a detrimental effect to the batch process performance, including both the batch quality and processing time. Even though most people would agree with this, exception handling is often an area of batch control system design not always given the level of attention it duly requires, even though it can have such a significant impact.

  • Personnel Tracking in Citect

    Personnel safety in heavy industries such as metals, mining and mineral processing is of paramount priority. This paper discusses the value proposition of having Citect possess the ability to deliver in real time, information about personnel that are present at or around the process that is currently being viewed on screen. Although the main driver is around safety, there are also potential benefits from a maintenance and support perspective.

  • Energy Monitoring: A Foundation for Effective Energy Management

    Energy Monitoring: Modern manufacturing processes run on energy. Electricity and natural gas are common inputs to all manufacturing. Other fossil fuels such as oil and coal are also widely used. Instability among global energy suppliers and increasing environmental impact concerns are causing many manufacturers to reevaluate their use of energy. In order to control energy use and the associated environmental impacts it is necessary to understand how and when energy is used. This paper describes a monitoring and control system that allows one major manufacturer to both understand and control their energy use. This has resulted in cost savings and understanding and control of greenhouse gas emissions associated with the manufacturing processes. The paper describes some details of a particular system, but the methodologies described have been used in multiple locations with similar success.

  • Experiences from Implementation of a Single DCS Solution Supplied by Multiple Module Skid Vendors and Utilizing the Principles of S88 as a Key Element

    The world of the pharmaceutical and biotech industries is becoming more and more complex. Business- production processes must be transparent in order to react quickly and accurate when necessary. Therefore engineering – and project execution methods for production facilities become more and more critical and demanding in order to achieve and realize safe pharmaceutical/biotechnology production. This paper will resume experiences (by examples) from a highly automated process plant (from the perspective of DCS/ process control) with well - structured collaborative engineering executions, procurement, construction management and validation, and management methods to meet above mentioned challenges. What seems simple or straight forward in theory (I.e. Standards and international guidelines) can become extremely difficult in reality, but for a multi vendor of process equipment project with a single DCS system it’s extremely important with precise project interpretation of standards/guidelines like S88 supported by well structured process – and automation oriented planning. In particular special focus will appear on global testing activities and strategies based on S88 principles, organized with multiple international process equipment skid vendors coordinated via one PCS vendor.
