Analysis of Component Supply System for Electronic Devices

The restorable electronic devices are being investigated. The system of necessary components supply used for realization of repair of devices is analyzed. The method of an establishment of requirements to an index of sufficiency of stocks a component is offered. The periodic ways of updating of stocks are being investigated. As an index of sufficiency the probability of sufficiency of stocks are being analyzed. The level of probability of sufficiency of stocks a component, at which total expenses in exploitation of the device are minimal, is required. The model of exploitation takes into account, that at failure of the electronic device instead of him other serviceable device is used. Expenses are calculated for the time, equal to the period of updating. At definition of expenses the created computer program is used. Some calculated values of probability of sufficiency of stocks are submitted in the table. Ill. 1, bibl. 3 (in English; summaries in English, Russian and Lithuanian).
