**5.1 Improving production capacity with production information feedback**

Susceptibility to constant change of elements which influence the calculation of the final product calls for the introduction of a mechanism on which real changes of factors for the calculation of production costs will be based. In addition to set elements (article price, work in process, materials, resources, cost depreciation) the set working times for all production operations in the finalization process have an important role. Since the final product is complex, its production is related with dozens of different operations. This is the area within which constant changes occur and where it is necessary to introduce mechanisms which will record such time changes based on which it will correct set input values. The result of that is the new corrected calculation which represents the actual state of the production resources in a particular structure. Figure 5 shows the model of production flow organization which can collect actual production information for correcting the set values.

In an ideal structure, automatic tools for selecting, analysis and transfer if information into the basis can be implemented, however the lack of such tools is evident in the resources for developing such complex operations (several different mechanical activities), which is why the production line is sometimes interrupted. It is on such resources that the embedding of tools based on manual duration production activities by workers involved in the production process is anticipated. In combining automatic and manual tools at the level of the entire production, all necessary production information can be obtained (real time, delays, problems) which significantly increase the existing structure. Furthermore, such tools can be used in status reports of each work order through the model of monitoring the production flow for each product. In such a way the production flow becomes transparent and monitoring becomes visible through planning models and the organization of production processes.

The model in Figure 5 encompasses the production environment within which the system for gathering production information is implemented. Setting up such a system demands considerable investment and taking responsibility of all participants in production operations by being independently engaged and in controlling for improving the quality of the final product.

Depending on the content of the work order is defined workflow and sequence of individual operations on the resource for making the product. Depending upon the operating times of individual phases is calculated the time occupancy of resources, and its planned occupancy of on a daily (short term) and over daily (long term) basis. This means

In information defined resources are installed a real properties of production, and is set informatics description of the working environment within which the simulation was tested. Research has focused on projecting of virtual manufacturing of components with all parameters and defined the production norms. The results of simulations of production contribute to the establishment of new ways to manage the existing work processes, and upgrading on overall planning of the production cycle. This tends to find a stable production plan, which is characterized by flow without delay from one side, and on the other side the financial profitability and competitiveness in the total price of the product. With simulation is also possible a planning and designing the working environment which is actual realization is predicted in future for a particular time period. With this approach it influence on opening and planning of new workplaces, on new organizational structures, and to increase the level of knowledge for managing production. Applying such approach allows the predictions of new work structures without causing damage and material costs.

that the same work order to occupy a different time-workload of particular resources after entering corrective factors received with backward connections. It wills also feedback production information will impact on change workflows in manufacturing the product in terms of seeking alternative and profitable work processes. With that comes to correcting the total cost of production, and thus to more competitive on the market.

In such a model, the input for calculating the production of the final product can be done by the external client (Figure 4) or internally by the person in charge within the organization (Figure 1, 2, or 3). Further creation of business documents is automatically generated based of the entered production elements.
