Overview of multi-attribute decision analysis tools for selecting an investment option in municipal heat energy

2024-01-25T19:28:36+01:00

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.

Use of Quick Response Quality Control (QRQC) method in process of problem-solving – case study

2024-01-12T20:30:25+01:00

The article presents an assessment of the use of the QRQC problem-solving method in the production line area in a selected enterprise. This method is used to comprehensively solve problems observed in various areas of the company’s operation, including: quality, safety and logistics. Based on literature research, the literature was analyzed and criticized, the researched method was characterized, the principles on which it was based and the levels of its application were presented. The stages of
the implementation of QRQC method as well as the participants and their roles in the problem-solving process were presented. Then, using the diagnostic survey method, a survey questionnaire was developed and research was conducted among a representative group of operators working on the production line in a company that has been using the QRQC method to solve production problems for many years. The research made it possible to assess the functioning of this method in the studied enterprise, determine its advantages and disadvantages, assess employees’ understanding of the rules, ease of use of the method and support received from management during the entire QRQC process. The research results will allow the company to make mature decisions regarding the use and improvement of the functioning of the QRQC method. The conclusions from the study can be used by other companies that use this method or want to use it in their problem-solving practice in an effective and
efficient manner.

Digital photogrammetry and CAD / BIM technology in the reconstruction of computer models for the concept of the Virtual Factory

2024-01-31T11:05:52+01:00

The research article aims to check the feasibility of combining digital photogrammetry and CAD / BIM technology to develop a 3D digital model for the concept of a Virtual Factory. The main objective of this research is evaluation and continuous improvement of all relevant processes of creating the spatial layout planning. During the research 3D floor plan of a laboratory was created to find matching common features for these methods. The article presents a comparative analysis of the time needed to create a spatial layout in which one can see exactly where in the spatial arrangement of point-to-point montage each particular element is placed. On this ground, one of the key elements determining the success of a design result is the effectiveness of the design process. Furthermore, the article indicates the scope of possibilities for using modern photogrammetric techniques to inventory buildings interiors and compare the speed of measurements processing using Photomodeler Scanner and ArchiCAD software.

Product in dentistry. Benefits obtained by the consumer/patient from the dental service

2023-12-15T21:03:59+01:00

Health care is a specific branch of the economy in which free market principles clash with state activity. Dentistry, however, is the part of health care in which commercial activity clearly dominates (although it is significantly regulated by legal regulations). Therefore, competition between entities providing dental services is significant and is relatively rarely based on the price of medical services, but rather emphasizes the benefits that the patient obtains by choosing a specific provider. The work is based on the case study method and personal observation as part of the implementation of professional duties in 2022-2023. It is intended to present the dental service as an extensive product with a wide range of benefits and values offered to the consumer. The work is also intended to give those entities operating on this market the opportunity to use good practices and adapt them in their activities.

Analysis of municipal waste management in the Municipality of Krakow

2023-08-03T17:34:28+02:00

Rational waste management is an essential element in the process of transition the linear economy into a circular model. Actions taken to achieve better results in this area are important for regional and local development as well as for the implementation of sustainable development goals. The article presents the requirements and rules for the functioning of waste management in Poland. Taking into account the structure of the system, the functioning of waste management in the Municipality of Krakow was analyzed. Particular attention was paid to the problem of municipal waste segregation by the inhabitants of Krakow. As part of own research, surveys were conducted among the employees of Municipal Cleaning Company LLC (Miejskie Przedsiębiorstwo Oczyszczania w Krakowie Sp. z o.o.), which showed the scale of the deficiencies. The results of the research were helpful in proposing actions to increase the effectiveness of the waste segregation system in Krakow.
