ABSTRACT

In-house material supply is one of the core factors for the flexibility and efficiency of manufacturing companies. This paper describes a procedure for planning and optimising tugger train systems for material supply. For this purpose a vehicle routing problem is developed, which should minimize the replenishment lead-time of the entire system by defining the routes and assigning the tugger trains. The paper describes the application of the heuristic model under different decision possibilities of the system design. The model offers the possibility to select different trip strategies, demand signal types, and afterwards optimise tugger train systems with a desired number of vehicles. Thus, the model optimises the performance of tugger train systems according to the individual requirements and objectives of a company.

ABSTRACT

 Reducing logistics costs is relevant at all times and at all stages of the logistics flow. The article considers the problem of reducing costs at the stage of procurement of raw materials, components, and also in the process of delivering products from the plant warehouse to the Assembly shop. To solve the set tasks a Japanese method "just in time"  was selected, applied attempt of using Kanban for the supply to the plant and its movement within the enterprise. However, in Russian conditions the use of such tool has failed owing to a lack of a clear organization of all processes. It was decided to implement a pilot project of optimization of supplies of metal products to the warehouse of the enterprise "Combine plant "Rostselmash", picking and delivering them directly into jobs Assembly plant. Thanks to improved logistics, changes in regulations and other documents were excluded intermediate stocks of hardware on pritsekhovaya pantries, reduced the complexity of the conversion, delivery, storage, reduced number of personnel: released 36 people (16 storekeepers, 16 movers, and 6 tractor drivers). The annual economic effect of the application of the adapted to Russian conditions of Kanban tool only for the delivery of fasteners from the warehouse to the shop amounted 18.4 mln RUB. Given that this is only one type of products, the gradual translation into cost-effective technology delivery to the enterprise and delivery to the shop can turn into an impressive figure of savings. The given example proved the possibility of using effective logistics technologies and tools to reduce costs, so it is recommended to expand the application for other engineering enterprises.

ABSTRACT

The paper deals with the systemic problems of corporate governance and risk management for high-tech projects. A logistic approach to the management of financial flows high-tech enterprise on the principles of proactive project management was discussed. Under this approach, the treasury model of new product development and project risk management has built, characterizing the future state of high-tech project and ensuring optimum utilization of financial and material resources.

ABSTRACT

The irrational organization of intra-productive material flows at the enterprise is the main reason of the increase of logistics cycle time and the emergence of additional logistics costs, reduce the capacity utilization rates, the difficulty of monitoring the production process and, as a whole, growth of the cost price of products. A study of intra-productive material flows in the company, engaged in the production and distribution of soft drinks, has revealed a number of significant problems associated with improper placement of the production equipment (mismatch between the location of the main principles of rational organization of production processes). In this article proposes an approach to the reorganization of the industrial material flow on the basis of the use of elements and instruments of various modern concepts of production logistics: Lean Manufacturing, Kanban, Theory of Constraints by E. Goldratt, Value Stream Mapping, REFA methodology. Proposals were developed on the spatial reorganization of the production process and improve the management of them with a view to ensuring the production line of the corresponding demand with minimal production and logistics costs. Given materials illustrates the effectiveness of the application of the presented approach to the production enterprise
