Combined make-to-order/make-to-stock supply chains

چکیده
A multi-item manufacturer served by a single supplier in a stochastic environment is considered. The manufacturer and the supplier have to decide which items to produce to stock and which to produce to order. The manufacturer also has to quote due dates to arriving customers for make-to-order products. The manufacturer is penalized for long lead times, missing the quoted lead times and high inventory levels. Several variations of this problem are considered and effective heuristics for the make-to-order/make-to stock decision are designed to find the appropriate inventory levels for make-to-stock items. Scheduling and lead time quotation algorithms for centralized and decentralized versions of the model are also developed. Extensive computational testing is performed to assess the effectiveness of the proposed algorithms, and the centralized and decentralized models are compared in order to quantify the value of centralized control in this supply chain. As centralized control is not always practical or cost-effective, the value of limited information exchange for this system is explored.

A Batch-wise ATP Procedure in Hybrid Make-to-Order/Make-to-Stock Manufacturing Environment
Satisfying customer demand necessitates manufacturers understanding the importance of Available-To-Promise (ATP). It directly links available resources to customer orders and has significant impact on overall performance of a supply chain. In this paper, an improvement of the batch-mode ATP function in which the partial fulfillment of the orders is available will be proposed. In other words, in...
متن کاملMTO-MTS Production Systems in Supply Chains
Increasing cost pressures have led supply chain managers to focus on running increasingly lean and efficient supply chains, with minimal inventory. Indeed, more and more firms are relying on pull or make-toorder (MTO) supply chains to minimize cost and waste. At the same time, increasing competitive pressures are leading to an increased emphasis on customer service. An important element of cust...

متن کاملMulti-site production planning in hybrid make-to-stock/make-to-order production environment
Today competitive environment has enforced practitioners and researchers to pay great attention to issues enhancing both production and marketing competitiveness. To do so, it has been obligatory for the firms to consider production side activities while customer requirements are on the other side of competition. In this regard, hybrid make-to-stock (MTS)/make-to-order (MTO) production systems ...
متن کاملApplying Stackelberg Game to Find the Best Price and Delivery Time Policies in Competition between Two Supply Chains
In this paper, the competition between two supply chains and their elements is studied. Each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. Therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...
