A) the master production schedule is a timetable that specifies what is to be made and when B) the master production schedule provides input to material requirements planning systems C) the master production schedule is a result of disaggregation D) the master production schedule is a sales forecast
Aggregate planning is an ongoing process. A plan usually provides details at the monthly level over the course of a year, and you should update it as conditions change. For example, you need to account for changes in expected demand as well as unexpected events such as material shortages and production …
Aggregate won from quarries may be of two kinds, depending on the local geology: Alluvial quarry: the aggregate won from alluvial quarries is the material deposited by rivers or glaciers. It can be excavated above the waterline, in benches 5 to 8 meters high, or it can be dredged in water.
For massive construction, aggregate particle size can exceed 1.50 inches (38 millimeters). Aggregates can also be classified according to the type of rock they consist of: basalt, flint, and granite, among others. Another type of aggregate is pozzolana, a siliceous and aluminous material often derived from volcanic ash. Reacting chemically with ...

The calcareous tuff impedes the bloating process of lightweight aggregate production. At 2,000 degrees F (1,000 degrees C), the calcite simply calcines. At high temperatures of over 2,200 degrees F (1,200 degrees C), diabase rock (specific gravity of 3.0) melts to …
Quarrying Process And Quarry Products. Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into the sizes required for immediate use, or for further processing, such as coating with bitumen to make bituminous macadam (bitmac) or asphalt.
Once the aggregate plan has been developed to give an overall production rate for the planning period, it is handed to production personnel. The operations and production personnel then break down the plan into weekly, daily and hourly schedules, in a process called disaggregation.

This process involves removing unwanted materials, such as blocks, clay, etc. The scalped product is crushed once to transform the block into broken stone. The process is repeated as many times as necessary to obtain the desired fragment size. The resulting material is then screened to obtain aggregates of the desired grade.

Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process. The two processes are essentially alike except in the wet process, the raw materials are ground with water before being fed into the kiln.
An aggregate plan provides the road map for business operations; it translates corporate strategy into a plan that can be implemented on the plant floor or on the front-line of service. For companies that sell physical products, this map details the production process. For service-based companies, the aggregate map identifies staffing levels and other resources […]
The production function, as a theoretical construct, may be abstracting away from the secondary factors and intermediate products consumed in a production process. The production function is not a full model of the production process: it deliberately abstracts from inherent aspects of physical production processes that some would argue are ...
