Therefore, manufacturers experience difficulties in scheduling production to satisfy anticipated sales, whilst ensuring that sufficient resources will always be on hand to execute the plan. Holt et al. (1955) defined the aggregate planning model, using a paint factory as an example. The basic concept is that the most economical solution …
As the demand for cement supply is continually growing, this causes an increase in the use of aggregate, especially limestone since it is important in the production of Portland cement [13], [14].Exhaustion of the earth's non-renewable resources is a growing dilemma when the reason is that the energy consumption has rapidly increased …
Production planning and scheduling are among the most important aspects to consider in a factory. Scientific analysis of the manufacturing process first began with Frederick Taylor (1911). ... levels. Sometimes, the tactical planning level is decomposed into two parts: aggregate production planning (APP) and master production scheduling …
Production planning models, and specifically aggregate planning ones are of the most popular models in medium term planning. Developing production planning model while focusing on energy saving can provide an efficient approach for optimizing energy consumption. As mentioned before, MOLP models are applied extensively in …
The paper shows how to derive a scheduling model from the factory specifications and presents a two-step heuristic procedure for its solution.

Aggregate production planning (APP) is a medium range capacity planning method that typically encompasses a time horizon anywhere from 2 to 12 months. A planner must make decisions regarding output rates, employment levels and changes, inventory levels and changes, as well as subcontracting to optimize the production plan.
The planning period considered is 18 months with a weekly solution horizon. A receding horizon approach from control theory, called model predictive control (MPC), …
