It is highly needed for the company to have such flexibility, agility and reliability in terms of answering the demand requests from their customers. But their limitations in improving customer satisfaction might be a big problem for them and the operation of single company can have a bad impact on those of the other companies in the supply chain, meaning that if one company fails to fulfill the demands required, it will affect the related companies and obviously will put them in jeopardy in terms

1. Vostick Filter Company is a distributor of air filters to retail stores. It buys its filters from several manufacturers. Filters are ordered in lot sizes of 1000 and each order costs $40 to place. Demand from retail stores is 20,000 filters per month, and carrying cost is $.10 a filter per month. a. What is the optimal order quantity with respect to so many lot sizes? b. What would be the optimal order quantity if the carrying cost were $.05 a filter per month? c. What would be the

A look at linear programming, using the simplex method Earlier in the class we were introduced to linear programming and now we are going to introduce a different method using a more geometric version called the simplex method. First, I am going to have to explain theory of the simplex method and then we’ll explain the real world uses of this algebraic math Ok, so earlier in the class we were introduced into liner equations and inequalities. With the simplex method we are going got look for

Iowa Elevators Case 1. Where would you start? With which of the purchase categories? It is wise to look at which categories have the most expenses: which in this case is the farm supplies, MRO/Construction and transportation services. It seems that combined, they account for approximately 75% of overall annual expenses. One should analyze why they are so high. 2. How much money do you think you can save in each of the next five years? It is hard to predict the savings because of limited information

When LINGO finds a solution to a linear optimization model, it is the definitive best solution¾ we say it is the global optimum. A globally optimal solution is a feasible solution with an objective value that is as good or better than all other feasible solutions to the model. The ability to obtain a globally optimal solution is attributable to certain properties of linear models. This is not the case for nonlinear optimization. Nonlinear optimization models may have several solutions that
