    Opis:
    The paper presents the issue of production processes improvement in foundries in the area of finishing treatment of iron casts manufactured on automated foundry lines with vertical or horizontal mould division. Due to numerous factors which influence the efficiency of the processes, multi-criterion assessment tools were proposed in order to select the optimal solution for the assumed criteria. After determining the criteria weight using the Saaty method, a simulation experiment was designed and carried out which presents possible scenarios of casts finishing treatment operations. Basing on experiment reports from a computer model, particular solutions were evaluated using the Yager’s method. The evaluation of the experiment results was performed by experts who assessed different options according to each of the criteria adopted. After the establishment of the total standardized ratings by averaging the scores given by individual experts, the final decision was generated. Using the presented method, the best solution was chosen from among the analyzed scenarios.

    Opis:
    The scope of this work focuses on the aspects of quality and safety assurance of the iron cast manufacturing processes. Special attention was given to the processes of quality control and after-machining of iron casts manufactured on automatic foundry lines. Due to low level of automation and huge work intensity at this stage of the process, a model area was established which underwent reorganization in accordance with the assumptions of the World Class Manufacturing (WCM). An analysis of work intensity was carried out and the costs were divided in order to identify operations with no value added, particularly at individual manufacturing departments. Also an analysis of ergonomics at work stations was carried out to eliminate activities that are uncomfortable and dangerous to the workers' health. Several solutions were proposed in terms of rationalization of work organization at iron cast after-machining work stations. The proposed solutions were assessed with the use of multi-criteria assessment tools and then the best variant was selected based on the assumed optimization criteria. The summary of the obtained results reflects benefits from implementation of the proposed solutions.

    Opis:
    The paper presents issues of production processes improvement in foundries in terms of finishing treatment of iron casts on grinding workstations. Basing on the conducted analysis of work ergonomics on the grinding line and the observation of work at workstations, a range of improvements related to organizing grinding treatment processes was proposed. In order to visualize the production system functioning and estimate its efficiency, a simulation model of a grinding line 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 most 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 analyzed options.
