IMPLEMENTATION PROCEDURE OF AN ADVANCED SUPERVISORY AND CONTROL STRATEGY IN THE PHARMACEUTICAL INDUSTRY
Abstract This paper describes the different steps followed in implementing a temperature controller and a supervisory controller in a Supervisory Control And Data Acquisition (SCADA) system to control a 60 and 160 l reactor in a pharmaceutical factory. These reactors are used to produce the initial quantities of drugs needed to perform clinical tests. The chemical reactions involved are often changed (several times a week). The different steps of the project will be presented: • design of a new heating–cooling system, • design of the predictive and Supervisory Control Algorithm (SCA), • connection of the SCA to the SCADA system, • experimental validation according to Good Manufacturing Practice (GMP). 
This SCA has been in daily use as the standard control system for more than 2 years.
A Safe Set Point Supervisor for MIMO Processes
In a previous paper we introduced a supervisory control framework for setting the operating point of an industrial process with unknown characteristics. Here we extend this methodology for the case of MIMO processes. The proposed supervisory control framework is agent-based and it involves modeling agents and intelligent agents. The modeling agents derive local steady-state models of the process during normal process operation by using various identification techniques, each of which corresponds to a different instantiation of our system. The intelligent agents are proposed to be implemented using finite automata units. The performance of the proposed scheme is illustrated through simulation results on well-known benchmark problems of chemical industry.
Warm Hands in Cold Age – On the Need of a New World Order of Care
The world is aging as fertility and mortality are both decreasing. This article focuses on practical care work for the elderly. Such work is done primarily by women even though a larger portion than previously is paid rather than unpaid. All over the world, most elderly care work is organized within the family, most often unpaid. Men receive more care from partners than women, while women receive more care from female relatives. When care work is paid, the payment is generally low. A comparison between Germany, Spain, and Sweden demonstrates similar gender patterns, even though the role of the state in supporting care differs considerably as do care workers' conditions. The sustainability of today's distribution and organization of care work is questioned as the need for care increases, and the possibility of more equal sharing of care work between women and men is explored.
