The EOQ model with items of imperfect quality and replenishment from different suppliers

The classical economic order quantity model is extended to the case where items may be acquired from various suppliers. It assumed that any lot size received a supplier contains perfect and imperfect quality items. percentage of in random variable having known probability distribution. are detected through 100% screening process conducted at start inventory cycle. When concluded, sold one batch discounted price. A mathematical developed determine total profit function. optimal proportions suppliers obtained by maximising Iterative numerical algorithms solution proposed. Numerical examples presented illustrate calculations when percentages follow uniform
