Summary Introduction
To calculate: The results with the changes made and identify its closeness to the example.
Inventory and supply chain models:
The functions of inventory and supply chain are one of the most important business decision areas for an organization. The first important aspect of these concepts is to have adequate inventory on hand. The second important aspect is to carry a little amount of inventory as possible.

Deltic sells this component for 55 per unit with a 4-month delivery lead time. Assume Deltic covers all transportation and related processing until delivery. TCX’s demand forecast for the upcoming selling season (12 months) is a normal distribution with mean 13500 and standard deviation 3736,4 . TCX sells each unit, after integrating their proprietary software, for 135. Assume that TCX uses a holding cost rate of 25 %, and any leftover units can be sold for 30 on average.
Due to the long lead time and high minimum order quantity required, TCX is planning on a single order from Deltic to meet their needs in the next year. How many of these components should TCX order? Calculate the resulting expected annual profits for TCX.
1. Solve the following exercise using dynamic programming: a company distributes an article with a demand of 15,000 articles per year, it is Considering that annual retention costs are $5 per item, it is estimated that the demand is delayed and this causes a cost of $10 per year. Everytime that an order is placed this causes costs of $50. The demand during the time of delivery follows a normal distribution with means of 200 units and a variance of 5 units.
3. Determine the optimum solution for Electro which uses 10000 gallons of resin per month in the manufacturing process. It costs about $100 to place an order. The storage cost is $3, the estimated backorder cost per gallon per month is $10. Assume that the demand follows a normal probability distribution, with an average of 100 gallons and a standard deviation of 4 gallons.

The anticipated demand is normally distributed with a mean of 731 units and standard deviation of 431 units. Tiptop purchases the snowboard from the manufacturer for $217 and sells the snowboard for $395. Any unsold snowboards at the end of ski season will be sold on clearance for $189.

- Consider a toy retailer with warehouses in St. Louis and Kansas City, Missouri. The warehouses stock an identical popular toy delivered to stores in the two cities. Assume a warehouse serves only stores in its city. Weekly demand for St. Louis is normally distributed with mean 2,000, and standard deviation 400 (that is N(μ = 2,000, σ = 400)). Weekly demand for KansasCity is distributed N(μ = 2,000, σ = 300). We assume that the two cities are far enough apart so that demand in the two cities is independent.The following parameters are seen by both warehouses:Replenishment lead time in weeks ~ N(μ = 2, σ = 0.1);Fixed shipping cost of replenishment: $500;Cost per toy: $10; andHolding cost per toy 20 percent of toy’s value per year.How many toys should each location order at a time and when should they reorder if they want a 99 percent cycle service level?

The retailer is planning to use a single centralized store in northern Ontario and they think the demand in the single store will be equal to the sum of the demand in all 7 cities. It takes 3 weeks for the supplier to send the products to the retailer.
