Noe 1 and 2 only have the supply as inflow, we call them the Supply Node. Node 6 only has the demand as outflow, we call it the Demand Node. The rest of the nodes are called Transhipment Node Let Si be the supply at node i and Dj be the demand at node j. Which statement regarding the general formulations of these nodes is true? A. For the Demand Nodej, the balance constraint is Σ(ijXi>=Dj B. For the Transhipment Node k, the balance constraint is ΣXik + Sk = ΣΧ

Case Located in the south of Turkey, Alanya Ice Cream Company produces and distributes 30 different ice creams. The products are distributed by the company itself, using their refrigerated truck fleet, to the hotels in Alanya. Its annual turnover is currently around 10 million TL. It is distributed among the hotels as indicated in Table 1. The company controls about 35% of the market, but this decreases below 10% in the countryside of Alanya where there are many smaller competitors. The company typically keeps stock in its central cold storage warehouses for up to four weeks to meet the distribution requirements of its six major customers. The operation of cold storage costs approximately 5000 TL per month. Storage costs are a significant expense, especially during the winter months when consumer demand is significantly reduced. Moreover, in summer, demand is sensitive to temperature. Therefore, the company estimates its sales based on increases in real spendable income. The Company…
d. The weekly average inventory listed above cannot change much since the grocery store is limited in storage capacity, and can therefore assumed to remain constant over time. The store has calculated that having less than 3 weeks of supply will create problems keeping stock available for clients. What annual cost of goods sold will bring about this condition (3 weeks of supply)?e. The grocery store is increasingly popular and management has calculated that, on average, the cost of goods sold increase by $5 million per year, reflecting better sales. How many years will it take for the grocery store to require expansion?

Casper Computer(CC) produces X model of computers of its own brand by assembling computer parts supplied from abroad and domestically, and sells them mainly domestically. The daily production capacity of CC is 30 computers. Assume that production continues throughout a week (7 days). The corresponding cost components for assembling, inspecting, and packaging per computer is $90, $80 and $20, respectively. Additionally, CC has a warehouse to hold finished computers in inventory for future deliveries and the weekly inventory holding cost per computer is $15. In order to provide quality service, CC wishes to meet all customer orders without shortage.
