Substantiation technique of spare parts' reserve for efficiency and reliability of a motor-vehicle fleet

Influence of reservation process of spare parts on efficiency and reliability of a motor-vehicle fleet is designated. It is revealed that negative influence on functioning of a motor-vehicle fleet renders imperfection of spare capacity norms. For increase of planning reliability of spare deliveries and also reduction of their dead stocks in a warehouse the author offers a substantiation technique of a spare parts' reserve based on use of nomenclature norms.

The coordinated-logistical centre as the mechanism of efficient control of transport nodal point

The concept of creation of the coordinated-logistical centres in the transport nodal points working in single information field is considered. The concept of the coordinated-logistical centre of transport nodal point is stated; its role and place in logistical system are shown. Principles of technological coordination of related kinds of transport in transport nodal points on all extent of a circuit of goods promotion from the producer up to the consumer are examined.

Algorithm of the decision of a problem task of the theory of turns

The common formulas of account of parameters of efficiency of multichannel systems of mass service (SMS) with final stores for turns are developed: an average holding time of the applications, share of refusals, degree of loading of a processing part. On the basis of it the algorithm of definition of rational parameters and structures projected SMS is given. All accounts are made without calculation of probabilities of condition of system through relative loading on SMS.
