Final answer:
The necessity for MRP to accept independent demand orders arises from the need for alignment with market forces and changing demands in order to maintain efficient production schedules and profitability. This integration optimizes responsiveness and competitiveness in an economy where market price and marginal revenue directly influence production levels.
Step-by-step explanation:
The concept of MRP (Material Requirements Planning) accepting independent demand orders is fundamentally tied to the need for businesses to be responsive to direct market demands. Independent demand is the demand for a finished product or an item that is forecasted and based on market conditions, as opposed to dependent demand, which is directly tied to the production of another item or product within the company. For instance, independent truckers, mentioned as part of the provided context, experience demand that is affected by various market forces, including the balance between supply and demand; similar to how MRP systems must also consider independent demand to effectively plan and schedule production or services.
Furthermore, when market prices increase, as detailed, this would naturally impact marginal revenue and subsequently production decisions. A rise in market price would prompt firms to increase production until their marginal cost meets the new increased marginal revenue, shown by the output level adjustment to a quantity of 90 where the new price equals marginal cost. If MRP systems did not accept independent demand orders, they would be less capable of adapting to changing market conditions, which would lead to inefficiencies and potential losses in profit due to unmet demand or missed opportunities.
In an economic environment, being aware of and responsive to independent demand is crucial; hence the role of MRP systems in integrating this aspect of demand into the production planning process is a critical one for maintaining competitiveness and economic efficacy.
