A type of weighted moving average forecasting technique in which past observations are geometrically discounted according to their age. The heaviest weight is assigned to the most recent data.

fixed reorder cycle inventory model
A form of independent demand management model in which an order is placed every n time units. The order quantity is variable and essentially replaces the items consumed during the current time period. Let M be the maximum inventory desired at any time, and let x be the quantity on hand at the time the order is placed. Then, in the simplest model, the order quantity will be M – x. The quantity M must be large enough to cover the maximum expected demand during the lead time plus a review interval. The order quantity model becomes more complicated whenever the replenishment lead time exceeds the review interval, because outstanding orders then have to be factored into the equation. These reorder systems are sometimes called fixed-interval order systems, order level systems, or periodic review systems. Syn: fixedinterval order system, fixed order quantity system, order level system, periodic review system, time-based order system. See: fixed reorder quantity inventory model, hybrid inventory system, independent demand item management models, optional replenishment model.F

option overplanning
Typically, scheduling extra quantities of a master schedule option greater than the expected sales for that option to protect against unanticipated demand.

A process to develop tactical plans that provide management the ability to strategically direct its businesses to achieve competitive advantage on a continuous basis by integrating customer-focused marketing plans for new and existing products with the management of the supply chain.

modular system
A system architecture design in which related tasks are grouped in self-contained packages. Each package, or module, of tasks performs all of the tasks related to a specific function and advances in functions can be implemented without affecting other packages or modules because of the loose coupling with other modules. One example is a multitiered architecture in which application business rules are separated from the data management rules. Another example is a client-server architecture in which user interface tasks are separated from the application software. See: open system architecture.M
