Štefan Meglen (2009) Upgrade of manufacturing information system. EngD thesis.
The dissertation deals with the upgrade of insufficiently developed manufacturing information system. Prior to starting the development, the possibilities and potential difficulties of development environment upgrade have been studied. Applied methodology, as well as development environment with its tools and database are discussed in the first part of the dissertation. The second part includes an overview of the manufacturing information system, focused on work order. A work order placement begins with a proper sales order. Data from the sales order is the basis to create a work order which a product engineer fills with placed material, work, and cooperation. Talking about offered work, we are taking a deeper look at the issue of additional data, so far written in the “notes” field. The concept of work order is finished with accounting, so this is the last step in the work order procedure in this dissertation. The third and most important part of the dissertation is the description of development and solution implementation, as well as a case study. Several possibilities of development are discussed, and the most appropriate one is chosen. We are showing the process of planning a solution, and a conceptual database model to implement the solution by RAD methodology. In the final part, we are presenting the conclusions we reached while developing our solution. Some difficulties are mentioned as well. The estimation of development environment upgrade adequacy is discussed. Development always creates new ideas, some of which are presented in the conclusion and made ready for new versions of a program.
