Enterprises using cranes, HDS platforms, other handling equipment, or pressure equipment in their activities are subject to registration with the Office of Technical Inspection (UDT), which is obliged to conduct inspection activities on them. Inspections of technical devices are aimed at checking their technical condition. Approximately 1.3 million technical devices are currently subject to UDT supervision in Poland. Annually, UDT inspectors carry out over 1 million tests of technical devices, and the activities carried out by UDT translate into a constant reduction in the accident rate. All this takes place in conditions that require continuous work planning and scheduling. This article aims to present and discuss the use of open-source solutions for planning the work of teams carrying out inspection activities, along with the concept of their use.

The article discusses a multi-criteria comparative analysis of GIS class computer systems using the Pareto method . Referring to this problem, to find a GIS system (a compromise solution) that would be acceptable for each decision criterion, to make a Pareto optimal decision, multi-criteria optimization was obligatory. To find the mentioned optimum (the Pareto optimum), it is necessary for the decision maker to make a choice concerning the set of admissible decision solutions. Here, a matrix of criteria constructed by the authors is available, filled in with appropriate weights by field experts. This structure is very useful when evaluating the admissible solutions of the resulting algorithm. The space of acceptable solutions in the considered problem task is a set of systems, limited to their eighteen instances, which meet the criterion of completeness of all data required in the conducted research. The selected criteria are the most widely used and most accepted in the environments that systems of this class use daily.

The article discusses the methodology of comparative analysis of GIS class computer systems using the current elements of taxonomy and classification theory. Eighteen selected GIS class systems that meet the criterion of completeness of all data required in the conducted research were fully analyzed. The proper comparative characteristics were preceded by the recognition of the market situation in terms of the availability of GIS systems. Eight thematic groups of criteria were used in the research, based on which the selection of GIS solutions for comparison was carried out. The adopted system selection criteria carry out the selection of objects in a binary manner. The chosen rules of classifying the system into a set of objects for comparison covered the issue of the availability of the required information. Due to the characteristics carried out, this information was obligatory, because a full set of data is required, which will allow for a comprehensive and factual comparison, based on which a given product (GIS system) can be indicated to the consumer with full responsibility. The set of features and comparative criteria was created based on own experience and numerous consultations with specialists and field experts. The selected criteria are the most widely used and most accepted in the environments that systems of this class use daily. Both the functional scope (features, functions, properties, advantages and disadvantages) as well as the degree of fulfillment of subsequent criteria by the considered systems were determined and described.
