Plano mestre de produção 6/8 - Acompanhando a demanda COM restrições

Understanding Production Management with Constraints

Introduction to Production Management

• The session begins with an introduction to the concept of production management, emphasizing the importance of managing demand while considering constraints.

• The speaker highlights that existing software can automate calculations, but the focus will be on using Excel for practical understanding.

Key Constraints in Production

• A critical constraint is established: a weekly production capacity limit of 16 units and a maximum availability of 90 units per week.

• The speaker notes that previous exercises did not have such restrictions, making this scenario more complex.

Calculating Available Resources

• A formula is introduced for calculating available resources: available = previous available - current demand + produced units.

• The importance of tracking negative values in production planning is discussed; negative values indicate unmet production needs.

Managing Demand Over Time

• The discussion shifts to how companies manage demand over time, stressing that producing too little leads to negative balances which are concerning for managers.

• It’s emphasized that there isn’t a one-size-fits-all solution; rather, adjustments must be made based on ongoing assessments.

Strategic Production Planning

• A mixed arrangement approach is suggested where production levels fluctuate according to demand peaks while adhering to constraints.

• The methodology involves working backward from future demands and adjusting current production plans accordingly.

Optimizing Production Capacity

• To minimize stock levels while meeting demand, it’s crucial to align production closely with peak demand periods (weeks 8 and 9).

• Maintaining maximum capacity during high-demand weeks ensures sufficient output without inflating inventory unnecessarily.

Final Adjustments and Results

• As adjustments are made throughout the planning period, it becomes clear that some weeks may require less than maximum output due to prior stock levels.

Production Planning with Capacity Restrictions

Understanding Stock Levels and Production Decisions

• The speaker discusses the observation of low stock levels across most weeks, noting that only week zero and week two had higher stocks. This indicates a need to manage production carefully given the constraints.

• A critical point is made about not increasing production unnecessarily when there is no demand, emphasizing rational decision-making in production planning.

• The speaker highlights that there isn't a single correct answer for production planning under restrictions; instead, they suggest following certain rules to guide decisions effectively.

• Two approaches are mentioned: calculating from back to front or adjusting through trial and error. Both methods aim to align production with actual demand while considering stock levels.

• The importance of timing in production is reiterated, stressing that producing too early can lead to unnecessary stock accumulation. The speaker aims to adhere closely to established guidelines for effective inventory management.
