Aggregate production planning for process industries …

1. Introduction. Traditional aggregate production planning models are usually cast in terms of allocating scarce resources and capacity to competing products (Hax, 1978) ).They are most commonly formulated as linear programs that minimize costs for a single producer, with products, demand levels and prices given.

The Aggregate Production Function

that question: a production function that relates the quantity of output produced to the quantities of inputs and the eﬃciency or productivity with which they're used. Doing this for an entire economy takes a leap of faith, but the reward is a quantitative summary of the sources of aggregate economic performance. The production function

Given the detailed network of production operations and their precedence relations (Fig. 56.2a), if only Finish-to-Start precedence relations are considered, then the aggregation causes a single precedence relation between two original operations to enforce a precedence relation between two aggregate activities (Fig. 56.2b). The feeding …

Introduction to Aggregate Planning and Strategies

Aggregate planning—which is also termed as sales and operations planning or macro production planning by Russell and Taylor-III and Nahmias and Cheng —is a process to support a company in determining levels of capacity, production, subcontracting, inventory, stock-outs, and pricing over a specified time horizon .
