    Single Facility Lot Size Model   Elsp Single Facility Lot Size Model Elsp Presentation Transcript

    • Single Facility Lot Size Model Producing n items on a single machine
      • Notation
        • λ j : Demand rate for product j
        • P j : Production rate for product j
        • h j : holding cost per unit per unit time for product j
        • K j : Set up cost for product j
      • Facility should have enough capacity to satisfy the demand of all products
    •  
    • Example data 20 0.003 80 10,000 1000 D 5 0.005 120 50,000 5000 C 15 0.002 70 5,000 2000 B 10 0.001 50 10,000 3000 A Variable cost/unit Setup time Setup cost Production rate Annual demand Product
    • Optimal Solution
      • T min = Σ s j /(1- Σ ( λ j /P j ) = 0.011/0.10 = 0.11 years
      • T* =((2)(320)/15,900)^0.5=0.20
      • Since T*> T min cycle length = 0.20 years
      • Q 1 =T* λ 1 =0.20 x 3000 = 600
      • Q 2 =T* λ 2 =0.20 x 2000 = 400
      • Q 3 =T* λ 3 =0.20 x 5000 = 1000
      • Q 4 =T* λ 4 =0.20 x 1000 = 200
      • Cost = 108,190
