Production Planning System
Priority > demand (relate to what, how many and when product are needed)
Capacity > resources (capability to produce goods and services)
Strategic Business Plan
- Marketing, whereby survey, promotion
- Finance, cash flow, budgets
- Production, satisfy to the demand
- Engineering, strategy to modify, redesign the product
Basic Strategies
- Chase(demand matching) > produce amounts demand at any given time
- Production Leveling > continually produce amount equal to average demand
- Subcontracting > always produce at minimum level demand (extra dd)
At below is the formula that use on this chapter!!!! Always remember this formula okay...
- Total production(TP) = ∑Forecast demand + Back order + Ending inventory – Opening inventory
- Annual Total Production(ATP) = TP/# of working days @ period
- Ending inventory = Opening inventory + Production – Forecast demand
- TP backlog = ∑Forecast demand + Opening backlog – Ending backlog
- Ending backlog = Opening backlog + Forecast demand - Production
