  This paper considers a complex scheduling problem in the chemical process industry involving batch production. The application described comprises a network of production plants with interdependent production schedules, multi-stage production at multi-purpose facilities, and chain production. The paper addresses three distinct aspects: (i) a scheduling solution obtained from a genetic algorithm based optimizer, (ii) a mechanism for collaborative planning among the involved plants, and (iii) a tool for manual updates and schedule changes. The tailor made optimization algorithm simultaneously considers alternative production paths and facility selection as well as product and resource specific parameters such as batch sizes, and setup and cleanup times. The collaborative planning concept allows all the plants to work simultaneously as partners in a supply chain resulting in higher transparency, greater flexibility, and reduced response time as a whole. The user interface supports monitoring production schedules graphically and provides custom-built utilities for manual changes to the production schedule, investigation of various what-if scenarios, and marketing queries.

• Simple Design and Control of ARCP-Inverter for Universal Power Range

  Abstract

  This paper illustrates the development of an ARCPI with a simple, fully digital control which works on the basis of pre-calculated switching time values stored in a look-up table of a PLD. Although the load current is the only measured input value of the control system there is no need for special driver-stages with a zero-voltage detection possibility. The PLD-control can be easily adjusted to cope with different input parameters and therefore it can be used in full power range without hardware changes. The paper presents the calculation models for the values of the resonant components and the switching times and compares the theoretical results whith the measurements carried out on two different test-setups in the mid and high power range.
