DEVELOPING THE AGGREGATE PLAN

Here are the steps in developing an aggregate plan: Step 1 Identify the aggregate plan that matches your company's objectives: level, chase, or hybrid. Step 2 Based on the aggregate plan, determine the aggregate production rate. If you use the level plan with inventories and back orders, the aggregate production rate is set equal to average demand.

How can we reduce concrete's hefty carbon footprint?

The process of creating cement emits upwards of 80 percent of the cement's weight in carbon dioxide and accounts for about 5 percent of human-generated CO2 emissions annually. Though the white block's production still requires some of the CO2-emitting fuel use of typical cement making, CO2 is also one of the ingredients used to create it.
