      <abstract xml:lang="ru">
        <p>При решении задачи оптимизации сроков службы машин и оборудования главным является выбор экономического критерия. В качестве такого крите­рия в разные периоды предлагались равенство затрат на очередной капиталь­ный ремонт действующей и приобретение новой машины, рентабельность продукции, приведенные затраты, среднеотраслевой годовой экономи­ческий эффект от замены действующих машин ...</p>
