Geographical Market Structure Local Local 1000 mi. Market Market No. 1 No. 2 700 mi. 700 mi. Central Market 1000 mi. 1000 mi. No. 5 700 mi. 700 mi. Local Local Market Market No. 4 1000 mi. No. 3
Facilities at any Local Market • Manufacturing plant of the firm of the local market • Raw material warehouse of same firm • Finished goods private warehouse of the same firm • Finished goods public warehouse of the same firm • Finished goods private warehouse of all other firms • Finished goods public warehouse of all other firms
Logical Decisions • Raw Material Purchasing • Production Scheduling • Warehousing / Inventory • Transportation • Finished Good Allocation • Sales Promotion
An Example for Transportation Decision • An order of 6 tons oat flour at week t • 3.5 tons by rail • 2 Car Load (2*1.5 tons) + 0.5 tonsLCL • 2.5 tons by truck • 3 Truck Load (3*0.7 tons) + 0.4 tonsLTL RM Purchasing Costt = 6 * 1500 RM Transportation Costt = 75*3 + 100*0.5 + 115*2.1 + 150*0.4 Shipments of • 2.5 tons oat flouris finished at week t • 3 tons oat flour is finished at week t+1 • 0.5 tons oat flour is finished at week t+2
An Example for Production Decision Available rice flour (2.8 tons) < Required rice flour (3.2 tons=400*0,008) Production made = 2.8 / 0.008= 350 units Production Charget = 1968 + 350 * [(350-243)/29)2 + 0.5] + 70 * 3.5 + 120 * 2 + (400 - 350) * 3.5
Inventory Management • Inventory (on hand) Carrying Cost = Oat flour on hand [tons] * 1500 * 0.15 + Barley flakes on hand [tons] * 2000 * 0.15 + Rice flour on hand [tons] * 3500 * 0.15 + FG on hand [units] * 250 * 0.24 • Raw Material (RM) available for productiont = RM transportedt + RM on handt-1 • RM on hand = RM in warehouse = RM available for production - RM used for production • Finished Goods (FG) available on salet [in Home Market (HM)] = FG producedt + FG on handt-1 - FG Shipment to Other Marketst • FG available on salet [in Other Markets (OM)] = FG transportedt + FG on handt-1 • FG on hand = FG in warehouse = FG available on sale - FG aggregate sales • Supply [by a firm in HM] = Shipment made to HM (“Supply to home” on Decision Sheet/Interface) • Supply [by a firm in OM] = FG available at market
