Opis:
Decision making supported by task-oriented software tools plays a pivotal role in a modern enterprise. That is because commercially available ERP systems are not able to respond in an interactive on-line/real-time mode. It opens a new generation of DSS that enable a fast prototyping of production flows in multi-project environment as well as an integrated approach to project execution evaluation. In that context our goal is to provide a knowledge base approach allowing one to be independent on a context or representation of particular data as well as allowing designing an interactive and task-oriented decision support system (DSS). The assumed knowledge base mode of specifying a production system leads to solving a logic-algebraic method (LAM) decision problem. The approach proposed complements the decision system with an additional module (evaluation module) and facilitates searching for possible solutions meeting company production programme execution evaluation criteria. The results obtained are implemented in a software package supporting project management in the SMEs. Illustrative example of the ILOG-based software application is provided.

Opis:
This paper presents the concept of topologies and investigation results of switched-capacitor voltage multipliers designed for application in high power systems. The analyzed family of multilevel converters includes established topologies as well as novel concepts. The application of thyristors as well as the invention of novel concepts of multiplier topologies and appropriate control make it possible to achieve high efficiency, high voltage gain, reliable and simple DC-DC converters for high power systems. Based on analytical models of the SCVMs, the paper presents a discussion of the selection of components and the efficiency of the converters as a function of converted power as well as the voltage range on the input and the output side. The results are supported by computer simulations and demonstrative experimental tests.
