In addition to their use as stand-alone systems, LPs are often included within larger systems intended for decision support. In this role, the LP solver is usually hidden from the user, who sees only a set of critical problem input parameters and a set of suitably formatted solution reports. Many such systems are available for supply chain management—for example, planning raw material acquisitions and deliveries, production and inventories, and product distribution. In fact, the process industries—oil, chemicals, pharmaceuticals—have been among the earliest users. Almost every refinery in the developed world plans production using linear programming. 

Supply Chain Collaboration and Negotiation since supply chain management across companies is a key objective, several authors focus on the management of the interface and collaboration between company supply chains towards a cross-industry supply chain the idea is that a collaboration between all companies from natural resource (e.g. metals) to end consumer product (e.g. cars) can lead to lower inventories, lowest costs and... 

In literature simulation and simulation-based optimization is focused on supply chain management areas such as production (Smith 2003 Wullink et al. 2004), inventory (Siprelle et al. 2003), transportation or integrated supply chain networks (Preusser et al. 2005).

Non-conflicting and unambiguous accountabilities are key to success. Supply chain managers are often held responsible for inventory levels but are unable to influence production lot sizes, which are normally under the control of the production managers responsible for production costs. As lot size adversely affects inventory levels and production costs, this is a common example of conflicting and ambiguous accountabilities, where responsibilities are not backed up by con-... 

Forecasting. Orders for long-delivery raw materials are issued at the corporate level based on the forecast for the demand for products. The current inventory of such raw materials is also maintained at the corporate level. This constitutes the resources from which products can be manufactured. Functions of this type are now incorporated into supply chain management. 

A traditional business s first encounter with e-commerce may well be as a supplier to one of the increasingly common Internet Web stores. Supply chain management is in fact a key, if not a critical, factor in the success of an Internet retailer. The number of products offered in a Web store depends not on available shelf space but on the retailer s ability to manage a complex sets of procurement, inventory, and sales functions. Amazon.com and eToys (http //www.etoys.com), for example, offer 10 times as many products as a typical neighborhood bookstore or toy shop would stock. The key application that enables these EC enterprises is an integrated supply chain. 

Multiple forecasts for the same line of business within the organization are common (if any planning is even done). The gap between what is planned and what actually happens represents lost profits and lost opportunities. The new paradigm for retail supply chain management begins with an accurate view of customer demand. That demand drives planning for inventory, production, and distribution within some understood error parameters. Consumers will never be completely predictable. At the same time, prediction is bounded by limitations in our statistical and modeling sciences. We can... 

The traditional trade-off in supply chain management has been the maintenance of costly buffers of inventory vs. the ability to meet complex customer prerequisites. Reduce safety stocks and costs will be reduced, but customer service may suffer. Due mainly to advanced planning and scheduling systems and improved forecasting applications, production planners now have the opportunity to reduce reliance on safety stock—while stiU meeting customer demand—by trading inventory for information.
