    Opis:
    In the paper on the base of literature review and also opinions of entrepreneurs dealt with fuel briquette manufacturing and also the data coming from selected enterprise a differential calculation model was worked out. First, circumstances of development of renewable energy sources sector in Poland were highlighted. One can indicate both high potential of renewable energy resources in Poland, big investments in this area last time and chances resulted in increasing demand for such kind of fuel and stimulating the EU legal requirements as well. Secondary, course of manufacturing and logistics processes of fuel briquette fabrication were analyzed considering relevant technical and economical parameters. Detail description of those processes let set crucial factors influenced studied fuel briquette production. This enabled elaboration of differential calculation model to set up interesting decision scenarios and simulate their different financial effects with marginal calculation method. Once can analyze impact of different levels of raw material humidity at unit cost of fuel briquette output. Next, financial effects of failures of crumbling machine influenced by polluted raw material were investigated. One can underline difficulty to precise probability of occurrence of such failures and to estimate accurately relevant costs closed to them. Third, elaborated model let simulate effects of different average transportation distance of enterprise from raw material location and also different prices of fuel. One can conclude that transportation costs are crucial for profitability of studied manufacturing process. Hence, worked out method of analysis of decision scenarios was verified positively as useful tool let update management in enterprises dealt with manufacturing of fuel briquette made from agro biomass. One can conclude that quality of raw material about level of pollution and humidity and also distance of its transportation and fuel price are crucial factors determining production process and shaping production costs, what is very important in planning.

    Opis:
    The analysis of the problem of the mechanical damage was made for a company manufacturing furniture and furniture fronts. From January to September the company identified 285 pieces of mechanically damaged products. The management of the company wanted to identify the source of the incompatibility; therefore, it was purposeful to analyse the problem of the mechanical damage using the sequence of the selected instruments of the quality management that enable this. Additionally, until now the company has not used the instruments of the quality managements to analyse the problems involving nonconformity, so it was important to show the company their practical use. The aim was to analyse the problem of the occurrence of the mechanical damage in fronts and furniture and to identify the root cause of the problem. Also to show the effective use of the sequence of the quality management instruments (i.e. 52WH method, Pareto-Lorenz diagram, Ishikawa diagram, 5Why method) to solve the problem of incompatibility. It was concluded that the root cause of the mechanical damage of fronts and furniture was the lack of management knowledge and awareness of the need to implement visualization principles in the company. The analysis and the proposed improvement actions may be practiced in other companies from both the production and service industries.

    Opis:
    Rolling wave planning is the process of planning for a project in waves as the project becomes clearer and unfolds. It is important in such projects to at least highlight in the initial plan the key milestones for the Project. Rolling Wave Planning acknowledges the fact that we can see more clearly what is in close proximity, but looking further ahead our vision becomes less clear [3]. Article shows benefits of rolling wave planning in production field. Based on the same data, there are two forecast calculations. First calculation is about current state of weekly cycle planning, second calculation is about future state of rolling wave planning (wave is the period of one day). Problem of current state is lack of production cells capacity, that makes costs of overtime. After research of implementing rolling wave planning there is shown estimations for new level of production cells capacity. New way of planning brings benefits in better aggregations, which reduce time for exchanges. Reduced time we can use for extra value-added process witch rise production cells capacity. Figure 5 include both calculations and final results.
