Lean production has in its Arsenal a huge amount of effective tools and methods for reducing the main types of losses. Those who are acquainted with lean production recently, such a number and variety of instruments raises many questions, e.g. in what cases and what tools to use. The complexity of these tools increases significantly when they are applied on machinebacon production, and in related fields, such as in warehouse logistics. How to reduce losses in the warehouse, applying the tools and techniques of lean manufacturing, says this article.

The article defines warehouses audit methodology and cases of companies which result essentially increases efficiency and warehousing quantity. Key Performance Indicators (KPI) and its values comparison with values of the whole in complex is considered as the main key element of audit methodology.

Key words. Logistics audit, quick audit, warehouse, Key Performance Indicators (KPI).

In the article economic efficiency of e-auctions in logistics is analyzed.

The article explains the practical methods for solving of optimization problems in transport and storage systems using their simulation models. The features of transport and storage systems models development and application, and an example of the optimizing the complex suspended monorail conveyor problem solving are described in this article.

Key words. Transport and storage systems, computer simulation, search methods for optimization.

The basis for an effective solution of problems of logistics systems is its formal description which allows the use of the mathematical apparatus of the theory of management. The article described a formal method of the description of the transport structure of the logistics system. Description allows the automatically synthesize a formal model of moving entities in the logistics system.

Key words. Logistic system, formal description, transport structure, moving entities.
