The customer market is becoming more and more demanding. Customers want to have influence on the final shape, form, functionality and characteristics of the product. As a result, entrepreneurs are forced to abandon the Make-to-Stock system in favour of the MTO (Make-to-Order) concept, with the purpose of not only meeting the customers’ needs, but also, for example, reducing the costs by manufacturing exactly the number of products which is currently demanded on the market. The article describes an example of a production task performed in the cellular structure. The customer required a substantial and abrupt increase (by 65%) of the production task. In order to tackle the problem, logistics engineering and lean manufacturing methods were applied. Having regard to the Industry 4.0 perspective, a concept of automated work cells was presented in order to minimise the role of the operator.

Storage of zinc wastes is associated with a high risk of environmental pollution. The way to manage the problem is using the waste materials in the transition process, the final product of which is the zinc oxide concentrate. Transition process is technologically complex and every failure to the discipline results in a large number of unscheduled stops. Such an issue was encountered by B. Recycling. An update of environmental regulations has forced a comprehensive modernization of the technology lines used. The implementation of new solutions brought the necessity of examination and evaluation of the effectiveness of the process. In the paper the analysis conducted for this purpose are described. The elements of TPM method were selected as the test method. The OEE, MTBF and MTTR values for the individual process lines and additionally for the most problematic subassemblies were determined basing on the research and collected data.

In the systemic approach, a production company is a complex system of objects and relations between the objects, as well as between the system and its surroundings. The large number of variables and company performance assessment indicators result in the constant search for the methods of formalising the mutual dependencies. The discipline which, through the integration of multiple processes, enables the discovery of practical solutions is logistics engineering. In Poland, the term is not very common, while in the USA (for example), logistics engineering – taking advantage of mathematical methods and cutting edge science, is a widely used tool supporting the everyday business activities of companies. The article describes primary tasks of logistics engineering in relation to production companies. Furthermore, original algorithms for the improvements of company productivity are presented.
