Factory Operations and Production Planning
- Time horizons in production planning include short term, long term, and medium term.
- Short term planning involves fixed capacity and resources, typically for a week or a month.
- Long term planning allows for complete changes in capacity and resources, typically for more than one year.
- Medium term planning falls in between short and long term planning and involves flexing current resources.
- Different businesses have different time horizons for their planning, based on their industry.
- Forecasting and capacity planning are important for making supply decisions and carrying out various planning activities.
- Forecasting helps in demand and inventory planning, while capacity planning involves production and distribution planning.
- Forecasting is challenging and often inaccurate, with two-thirds of sales forecasts having a margin of error exceeding 25%.
- Poor forecasts can lead to excess inventory or poor availability of products, causing financial and logistical issues.
- Improving the match between supply and demand can be achieved through communication, collaboration, and robust baseline forecasting.
- Integrated cross-functional planning is necessary for aligning demand and supply planning processes across different functions.
- Capacity planning involves determining the maximum output rate that can be achieved by a facility and reconciling customer demand with input resources.
