B of long lead times associated with product development and building capacity, a supplier must initiate investment in capacity when the product development effort is ongoing. Because the product is ill defined at this point in time, the buyer is unable to commit to the future terms of trade through a courtenforceable contract. Instead, to provide incentives for capacity investment, the buyer i...

In this paper a model is proposed for distribution centers location and joint replenishment of a distribution system that is responsible for orders and product delivery to distribution centers. This distribution centers are under limitedwarehouse space and this can determine amount of requirement product by considering proposed discount.The proposed model is develop to minimize total costs cons...

In contrast to the classical newsboy-style problem, this paper develops a model for the multiple-item budget-constraint newsboy problem considering a reservation policy to meet marketing needs. A discount rate is provided to those customers who are willing to make a reservation. In addition to the demand from the original customers, extra demand is also included in the model due to the motivati...

In this paper, a nearly real-world multi-product, multi-period inventory control problem under budget constraint is investigated, where shortages in combination with backorders and lost sales are considered for each product. The ordered quantities of products are delivered in batch sizes with a known number of boxes, each containing a pre-specified number of products. Some products are purchase...

Selling organizations often offer quantity discounts schedules, but do not provide the underlying Quantity Discount Price Functions (QDPF). In literature an analysis on how QDPF could be derived from discount schedules is lacking. This is remarkable as QDPF contain useful information for buying organizations. QDPF give more insight into the fixed and variable costs of selling organizations and ...

This study revisits a fuzzy rough economic order quantity (EOQ) model for deteriorating items considering quantity discount and prepayment. Since the proposedmodel is amixed integer nonlinear programming type, it is solved using Meta heuristic algorithms. Based on three different case examples, we have shown that our results using the Bees Colony Optimization (BCO) algorithm performs better tha...

    Supplier selection,   Multi-objective decision making,   Fuzzy Compromise programming,   Supply chain management,   Quantity discount .   Supplier selection is naturally a complex multi-objective problem including both quantitative and qualitative factors. This paper deals with this issue from a new view point. A quantity discount situation, which plays a role of motivator for buyer, is con...

Original scientific paper High uncertainty and variability of acquirable cores can lead to some difficulties of operations management in the remanufacturing process. Two acquisition models with quantity discount and carbon tax scheme were established to analyze the effect of quality variability and condition uncertainty and to reduce these difficulties. In the first model, quality variability w...
