Opis:
The paper presents a scheduling production problem in foundry equipped with one furnace and two casting lines, which provides a number of different types of castings for a large number of clients. The amount of molten metal may not be greater than the capacity of the furnace and its load is a type of metal, from which the products are manufactured on automated casting lines. The purpose of planning is to create the processing order of metal, to prevent delays in the delivery of the ordered products to the customers. This problem is mixt of lot-sizing problem and scheduling problem on two machines (the lines) running in parallel. The article gives a mathematical model, which formally defines the optimization problem, and his relaxed version which is based on the concept of rolling-horizon planning. The proposed approaches were tested on the sample data.

Opis:
The paper presents issues of quality management related to iron casts manufactured on automated foundry lines for automobile industry. The influence of the choice of electric furnace and automated foundry line with vertical or horizontal mould division on the quality of casts made of nodular or grey cast iron was presented. Analysis of different scenarios of the course of action manufacturing processes was performed basing on a simulation experiment, record data related to the quality of the manufactured casts and manufacturing prime costs analysis. The research used universal tools applied in simulation analysis of production systems (Rockwell Automation: Arena Simulation Software) and a spreadsheet used for cast manufacture cost estimation. The proposed variants have been assessed using the Pareto analysis on the basis of results of reports generated for a simulation experiment. The paper also presents suggestions of activities aimed at further improvement of the quality of foundry processes.

Opis:
The paper presents a practical example of improving quality and occupational safety on automated casting lines. Working conditions on the line of box moulding with horizontal mould split were analysed due to low degree of automation at the stage of cores or filters installation as well as spheroidizing mortar dosing. A simulation analysis was carried out, which was related to the grounds of introducing an automatic mortar dispenser to the mould. To carry out the research, a simulation model of a line in universal Arena software for modelling and simulation of manufacturing systems by Rockwell Software Inc. was created. A simulation experiment was carried out on a model in order to determine basic parameters of the working system. Organization and working conditions in other sections of the line were also analysed, paying particular attention to quality, ergonomics and occupational safety. Ergonomics analysis was carried out on manual cores installation workplace and filters installation workplace, and changes to these workplaces were suggested in order to eliminate actions being unnecessary and onerous for employees.
