A SPC strategy for decision making in manufacturing processes
(AGH University of Science and Technology Press, 2019) Gil Del Val, Alain; Sawik, Bartosz; Alba, Maria Agustín Martin; Faulin, Javier; Diéguez-Elizondo, Pedro María
Tapping is an extensively employed manufacturing process by which a multi-teeth tool, known as a tap, cuts a mating thread when driven into a hole. When taps are new or slightly worn, the process is under control and the geometry of the resulting threads on the workpiece is correct. But as the tap wear increases, the thread geometry deviates progressively from the correct one and eventually the screw threads become unacceptable. The aim of this paper is to outline the development of a statistical process control strategy for decision making based on data coming from the current signal of the tap spindle for assessing thread quality. It could operate on line, and indicates when the tap wear is so critical that, if the process were continued, it would result in unacceptable screw threads. The system would be very cost-effective since the tapping process could be run without any operator intervention.

Overview of multi-attribute decision-analysis tools for selecting investment options in municipal district heating systems
(Wydawnictwa AGH, 2023) Dawiec, Dominika; Ginda, Grzegorz
Municipal district heating systems in Polish cities constitute important elements of these municipalities (and not only of their technical infrastructures). Due to the nature of the basic service that is provided – providing heat (and perhaps year-round comfort in the future) – these systems can be perceived as important parts of the social infrastructures of the cities, creating the appropriate conditions for the existence of people, the functioning of social infrastructure facilities, and the operations of enterprises. The need for heating companies to adapt to any changes in the requirements that arise as a result of the economic, social, environmental, and (increasingly) political and legal changes that take place in its immediate and distant environment requires the implementation of investments. However, the effects of such investments are multidimensional and largely difficult to measure, they depend on the passage of time and complex conditions that are related to the pursuit of sustainable development and security. Their reliable assessment therefore requires the use of appropriate tools. This paper is devoted to an analysis of the practical usefulness of multi-attribute decision-analysis tools in this context, taking various types of such tools into account as well as the conditions for their effective applications. The most promising of these tools is also introduced and discussed.
