GA1 & 5 Identify / Define Problem 1. What is the aim to study Aggregate Planning? List five Capacity Options? 2 5 5 2. Define and give Five Aggregate Planning Methods Contextualize the problem: Monthly data related to Benga's Ladder Manufacturing has been presented. These are monthly forecast of prodducts over a 12 month period. Demand per day Expected demand 500 Production days 22 18 600 21 600 700 21 700 800 Month January February March April May June July August September October November December Total Cost Information: 22 20 21 900 900 800 21 20 22 700 600 600 20 18 246 8400 Stock out cost $50 per unit Sub-contracting $40 extra per unit Maximum of 1500 extra units per month - Beginning inventory > 100 units Overtime Maximum of 200 units per month $10 extra per unit - Holding Cost Inventory $10 per unit based on count at month's end - Inventory carrying cost $3 per month - Present work force - 700 ladders/ month Cost is $ 70 per ladder at 700/mo. > Cost is $75 for each ladder OVER 700/mo. If less than 700 ladders/mo. Cost is $82 per ladder - Backorder (shortage) cost per ladder $10 per month 2 Formulate strategies for solving a problem: The firm would like to begin development of an aggregate plan. Develop it Understand Tools: 3. Determine daily and average demand (manually and graphically) 6 3 Recognize and consider assumptions: 4. Give the name of the three plans. Identify and Use Tools: 5 Construct a table that accumulates the costs Propose/ Create Multiple solutions 45 6 Develop an Aggregate planning a. Plan 1 b. Plan 2 c. Plan 3 Analyse, evaluate and select solutions: & Create Tools & Evaluate Tools 7 Interpret the results GA3 | 7
