In late 2006, Pfizer launched its smoking cessation film-coated tablets. All of the process stages (granulation, product varenicline, known as Chantix® in the US tableting and coating) are controlled and monitored from and Champix® across Europe. According to IMS a separate control room so that employees do not come benchmarks, Champix® was the fastest product launch in into contact with dust that might be generated during the the European pharmaceutical industry, with marketing tablet production run. Transport is handled by automated, in 16 European countries in a five-month period. As well and entirely robotic, laser-guided vehicles. Operators as creating rapid and unprecedented consumer demand, monitor and control all containment room activities from the product launch also brought capacity challenges for a separate control room. Pfizer Inc’s small-scale IllertissenCONtainment (ICON) facility in Illertissen, Germany. The facility’s innovative IT systems integration enabled an extraordinary 85 per cent level of automation (LoA), A strategic site in Pfizer’s global manufacturing network, outstripping even the ICON facility’s extremely high 76 per Illertissen is focused on oral solid dosage forms and is a cent LoA. Thus, in NEWCON, all process sequences centre of excellence in containment production.

Jotta laitoksen informaatiosta saadaan parempi koko- naiskuva, tarvitsee se mallintaa jollakin tekniikalla. Kun laitoksen mallintaa hierarkki- sesti, pystyy sen rakenteen hahmottamaan helpommin. Lisäksi, kun malliin saadaan tuotua mittaussignaaleja ja muuta mittauksiin ja muihin arvoihin liittyvää dataa, saadaan se tehokkaaseen käyttöön. Nykyään paljon käytetty klassinen OPC tuo datan käytettäväksi ylemmille lai- toksen tasoille. OPC tuo mittaukset pelkkänä listana, eikä se tuo mittausten välille mi- tään metatietoa. Tässä työssä on tarkoitus tutkia, miten mallintaa esimerkki laitokset käyttäen klassisen OPC:n seuraajaa OPC UA:ta. Työn tavoitteena on tutkia eri OPC UA:n mallinnustyökaluja, menetelmiä ja itse mallinnusta. Työssä tutustutaan OPC UA:n lisäksi ISA-95:n ja sen OPC UA- malliin ja miten tätä mallia pystyy käyttämään oikean laitoksen mallinnuksessa hyödyksi. ISA-95 lisäksi tutustutaan toiseen malliin nimeltä CAEX. CAEX on alun perin suunniteltu suunnitteludatan tallentamiseen stan- dardoidulla tavalla. CAEX:sta on olemassa myös tutkimuksia OPC UA:n kanssa käytet- täväksi ja tässä työssä tutustutaan, onko mallinnettavien tehtaiden kanssa mahdollista käyttää CAEX:ia hyödyksi. Virallista OPC UA CAEX- mallia ei ole vielä tosin julkais- tu.

Differentiate between Quality and Quality Management Elaborate the concept of Total Quality Management 1.1 Introduction Quality is a buzz word in our lives. When the customer is in market, he or she is knowingly or unknowingly very cautious about the quality of product or service. Imagine the last buying of any product or service, e.g., mobile purchased last time. You must have enquired about various features like RAM, Operating System, Processor, Size, Body Colour, Cover, etc. If any of the features is not available, you might have suddenly changed the brand or have decided not to purchase it. Remember, how our mothers buy fruits, vegetables or grocery items. They are buying fresh and look-wise firm fruits, vegetable and groceries. Simultaneously, they are very conscious about the price of the fruits, vegetable and groceries.

  • Kpis As the Interface Between Scheduling and Control
    Preprint, 11th IFAC Symposium on Dynamics and Control of Process Systems, including Biosystems June 6-8, 2016. NTNU, Trondheim, Norway KPIs as the interface between scheduling and control Margret Bauer1, Matthieu Lucke2,3, Charlotta Johnsson3, Iiro Harjunkoski2, Jan C. Schlake2 1University of the Witwatersrand, Johannesburg 2050, South Africa (email: [email protected]) 2ABB Corporate Research, Wallstadter Str. 59, 68526 Ladenburg, Germany (email:[email protected]) 3Department of Automatic Control, Lund University, 22100 Lund, Sweden (email [email protected]) Abstract: The integration of scheduling and control has been discussed in the past. While constructing an integrated plant model that may still seem out of reach, scheduling and control systems are increasingly more intertwined. We argue that they are in fact already integrated and give the example of two key performance indicators (KPIs) that are defined in the recent international standard ISO 22400. The focus of this study is on KPIs that consider both planned times and actual times. An amino acid production plant is used in the study, and the production is described from both the scheduling and the control perspective. To illustrate the integration, a schedule is computed containing the planned production times. Resulting measurements from the control system are analyzed for their actual production times using a proposed procedure that detects the start and end time of batches. Using KPIs as the interface between scheduling and control can be used as a strategy for maximizing the plant performance. The study focuses on the process industry. Keywords: Integration between scheduling and control, key performance indicator, distributed control system, planning and scheduling, batch process.

  • Control System
    Control system A control system is a device, or set of devices to manage, command, direct or regulate the behavior of other devices or system. There are two common classes of control systems, with many variations and combinations: logic or sequential controls, and feedback or linear controls. There is also fuzzy logic, which attempts to combine some of the design simplicity of logic with the utility of linear control. Some devices or systems are inherently not controllable. Overview The term "control system" may be applied to the essentially manual controls that allow an operator, for example, to close and open a hydraulic press, perhaps including logic so that it cannot be moved unless safety guards are in place. An automatic sequential control system may trigger a series of mechanical actuators in the correct sequence to perform a task. For example various electric and pneumatic transducers may fold and glue a cardboard box, fill it with product and then seal it in an automatic packaging machine. In the case of linear feedback systems, a control loop, including sensors, control algorithms and actuators, is arranged in such a fashion as to try to regulate a variable at a setpoint or reference value. An example of this may increase the fuel supply to a furnace when a measured temperature drops. PID controllers are common and effective in cases such as this. Control systems that include some sensing of the results they are trying to achieve are making use of feedback and so can, to some extent, adapt to varying circumstances. Open-loop control systems do not make use of feedback, and run only in pre-arranged ways.

As a result, the management and integration of data in a consistent, organized, and reliable manner is a big challenge for the pharmaceutical industry. In this work, an ontological information infrastructure is developed to integrate data within manufacturing plants and analytical laboratories. The ANSI/ISA-88.01 batch control standard has been adapted in this study to deliver a well-defined data structure that will improve the data communication inside the system architecture for continuous processing.
