The article presents research results in a scope of evaluation importance of safety in the workplace in the production processes of enterprise from metal products industry. Toyota's management principles by Jeffrey Liker were pointed out, which refers to elements of Toyota’s house roof. An innovative BOST questionnaire survey was characterized as a tool for transformation of Toyota's management principles into questions. Research group which participated in BOST study from the metal product industry was characterized. Research results were subjected to statistical analysis with a use of basic statistical parameters. Research results showed that safety in the workplace is important factor in the company.

The paper presents the possibilities of the application of different models for blast furnace operation management: thermodynamic and kinetic models and also coke degradation model. Thermodynamic and kinetic approaches in modelling metallurgical processes form are necessary basis for continuous analysis of the conditions under which the evaluated iron technology can actually work while achieving the highest productivity. They can be also useful for estimating of maximal rate of auxiliary fuels in specific conditions of the blast furnace iron making, what can help to optimize the cost of fuels. The aim of the article is to present the possibility of reducing the costs of pig iron production using models, especially the coke degradation model, which was used for Czech conditions. The model was developed in two options: a regressive non-linear statistical model, and a selflearning neuron network. Subsequently, both predictive model variants are compared.
