The methods of pull flow production management allows the manufacturing of products in the client production rhythm and has the fallowing characteristics: the production planning is based on the daily production capacity and on the received orders from the clients; the products are manufactured in small batches and in continuous flow; they need well leveled production lines; aim cost reduction, short response for clients demand, increase of productivity and stock reduction.

The aim of this paper is to determine the impact of the Kanban-Conwip-Base on stock hybrid production control method, varying several factors between certain limits, on the exits of the system, determining production performance indicators.

To reach the intended objectives we started from an existing production line that manufactures two types of products. From the manufacturing flow were considered four consecutive operations that were controlled using the hybrid method Kanban-Conwip-Base on stock.

The main conclusions taken after analyzing the manufacturing system that was controlled using the hybrid method Kanban-Conwip-Base are shown in the following. These conclusions are valid for the variation intervals of the considered entry parameters: the work in process stocks rise with the increase of daily demand and decrease with the increase of number of setups done daily and the cots on the product decrease with the increase of daily demand and rise with the increase of the other two parameters: holding cost and number of daily setups;

Also, the made researches are on the influence of the production factors, and none yet are on the influence of more of them in the same time. Starting from this premises and considering the perspective of its use in the industrial enterprises, the researches made in this article aimed to analyze the impact of hybrid production control method Kanban-Conwip-Base on stock, in the conditions of variable entry data (in certain limits), on several performance indicators of the production line and to elaborate recommendations on applicability of the research results.

It is considered that the research done in this article bring original contributions, useful research purposes and also for industry, on several important directions of conception and control of production systems. A first contribution is the methodology used to choose the optimum control method for the performance indicators, taking into account several parameters as daily demand, number of setups, holding cost. The second contribution brought by this research is linked to the IDEF0 functional modeling method used on the hybrid production control method Kanban-Conwip-Base on stock. The third contribution is linked to the usage of SIMAN language to make the dynamic simulation of the production line on this specific control method. Starting from the developed model were determined the loading period of the system, the simulation duration and also the methodology of simulation validation.
