Opis:
This article presents an original methodology of implementation of repeatable production plan. After analyzing the available literature, both Polish and world, and their own thoughts, it was found that the available methods of implementation production leveling are imprecise or difficult to implement in real conditions. Accordingly, an attempt was made creation of such to the methodology that would be simple to implement the in enterprises. The methodology consists of six steps procedure. The first step is to choose products which will be implemented leveled production. For this purpose uses a sieve Glenday. Sieve Glenday allows it to designate products made of green group that is, those that are most commonly sold. The next step is the division of products families, according to the similarity criterion of technological products. For this purpose uses matrix similarity technological products. The third step is the analysis of customer orders for products from the green group. For this purpose to be determined the average weekly sales of products. Then, on the basis of the forecast is calculated weekly forecast accuracy. This step is particularly important to the company so far has proven demand fluctuations and verifiability forecasts. The fourth step is to determine the frequency of repetitions production products. This is done using EPEI gauge, which informs how often it is possible to produce the next sequence products.. The next step is determining the volume of stocks: cycle, buffer, safety in the warehouse of finished products. In the production leveling it said that the store is called. Supermarket different from the traditional magazine primarily that is always retained FIFO. The last step is to create reproducible production plan. To check the leveling of production to be determined gauges the effectiveness of the leveling of production, for example volume of stocks, production capacity, etc. Evaluation of effectiveness of the leveling of production is particularly important because it helps determine whether production leveling brought the desired effect or not. Presented in the article the methodology is under development. The next step of the work will attempt to test the methodology in real conditions in the enterprise.

Opis:
The article presents an analysis of three options to reduce the share of changeovers time in the available time of working machines. The first option concerns the reduction of the number and share of changeover times by grouping them in the production schedule by technologically similarity. The similarity is understood as production of products using the same settings of machines or using the same equipment. For the purpose of such approach patterns of clustering and queuing production orders in work schedules machines are formed. This enables the rapid and substantial reduction in the share of changeovers in the available working time of machine without interfering with the retooling process itself. By only knowing the structure of retooling and extract these essential elements, which by pooling and templates queuing can be avoided. In this case, increase the efficiency of the machine is achieved, however, at the same time stocks of both semi-finished and finished products increases and extends the duration of the customer contracts internal or external. The second variant is related to the analysis of the effect of shortening changeover times on the availability of machines. This approach was applied to organizational changes of retooling of machines in accordance with SMED method. This requires the involvement of all people involved in the process and examine depth of the whole process of retooling. At the same time this allows for a significant improvement in the efficiency of the machine without increasing inventory and maximizing production orders. The third analysis includes the simultaneous application of queuing pattern of production orders for individual products in the schedules of the machine and to shorten setup times. This approach allows for rapid improvement of the equipment with relatively low effort and cost.
