У статті розглянуто особливості ризику виявлення браку підприємств з виробництва штучних продуктів електричного устаткування. Авторами здійснено постановка задачі мінімізації витрат внаслідок виявленого браку. Сформульовано модель оцінки додаткових абсолютних та відносних витрат, що пов’язані із системою управління ризиком виявлення бракованої продукції у пар-тії. За допомогою апарату теорії імовірності обґрунтовано метод розрахунку резервного фонду готових до випуску товарів, а також рівень додаткових затрат на кожну партію готової продукції. Цільовими критеріями моделі визначено рівень втрат від виявлення браку та додаткові витрати на покриття негативних наслідків ризику. Для підприємства з виробництва електричного устаткування здійснено апробацію практичної економічної ситуації. Отримані результати дали змогу визначити залежності величин відносного рівня ризику для кожної партії продукції.
Risk is an integral part of economic systems: production, financial, social and so on. Therefore, the risk of production defects is quite common for manufactur-ing enterprises. The article discusses the features of the risk of defects detecting for enterprises, which produce piece type of products, in particular, electrical equipment. The problem of identifying defective goods could be solved by creating a reserve fund for additional products, in which several similar units are added to each consignment of manufactured products for quick replacement and minimization of the negative consequences of the defect. The authors formulate the problem of minimizing costs due to the revealed defect. A model for assessing additional absolute and relative costs associated with the risk management system for detecting defective products in a consignment is formulated. The method for calculating the reserve fund of ready-to-release goods as well as the level of additional costs for each consignment of finished goods, based on the apparatus of the theory of probability, is substantiated. The target criterion of the model is determined by the level of losses from the defect detection and the additional costs to cover the negative consequences of the risk. The model for estimating the mathematical expectation of absolute and relative costs of possible defects detection in a consignment of artificial goods, which is based on the binomial distribution law, is proposed. A practical economic situation has been tested for an enterprise of electrical equipment production. An assessment of the input parameters is carried out and a mathematical model is built for assessing the costs of detecting defects of the corresponding enterprise. The obtained results made it possible to determine the dependences of the values of the relative level of risk for each consignment of products. The level of marginal costs from the implementation of measures to manage the risk of detecting defects has been determined. It is also proven that the level of relative risk of the defect detection is significantly influenced by the size of the consignment.
