The paper presents issues of production processes design and improvement. In order to visualize the production system functioning and estimate its efficiency, a simulation model has been created, on which a simulation experiment was carried out. Due to many factors influencing the effectiveness of processes, it was suggested to use multi-criteria evaluation tools to choose the rational solution. Three criteria have been assumed, according to which particular improvement variants were evaluated. Also, criteria weights have been set according to the Saaty’s method, and particular solution variants have been assessed separately with respect to each criterion. On the basis of the presented course of action, the best solution has been selected from among the analysed options.

The aim of this research is to propose particular measures aimed at streamlining costs in terms of operations in a selected company. A specific proposal is based on the concept related to using services of the transport databank. As at least two out of five major carriers of the investigated company resell shipments to other carriers on such portals, the company could reduce the transport costs by entering shipments into the transport databank on its own. One out of three selected providers will be chosen using multi-criteria evaluation methods, specifically, the Analytic Hierarchy Process (hereinafter referred to as AHP) and the Base-criterion method. Determination of the weights of criteria will be carried out using the Saaty method of quantitative pair wise comparison and the Fuller pair wise comparison method. In this paper, the presented methods are applied for the example of a specific company specialized in the manufacture of metal storage racks and steel structures. In the Czech Republic, the company employs 65 employees in production, storage and administration. Based on the analytical evaluation of the current situation of the company, relevant measures will be proposed with a required effect on the effectiveness of such an enterprise.

Proces oceny i podejmowania decyzji zawsze jest oparty na kreowaniu pewnego modelu. Model matematyczny oceny wielokryterialmej ma na celu przedstawienie wariantów, ograniczeń, kryteriów i zależności między nimi, za pomocą których można w sposób przybliżony opisać jakiś aspekt rzeczywistości.

This paper describes the using fuzzy logic to evaluate alternative project execution schedules. The multi-criteria evaluation based on the criteria proposed by experts or decision-makers in the planning phase, during which it is critical to document the tasks to be completed in a project schedule.
