Linear problem with no short cuts
LP Intro An optimization method Either minimization or maximization What decisions do we have control over (Decision variables) Without constraints/limitations we could drive profits to positive infinity or costs to zero (negative infinity) But, we have constraints that we need to abide to We will model the problem and then hand over to excel to solve Wyndor Two decisions: How many units to

intentionally limited. the counter will offer a regular mix of candy made up of equal parts of cashews, raisins, caramels, and chocolates, and a deluxe mix that is one-half cashews and one-half chocolates, which will be sold in one-pound boxes. in addition, the candy counter will offer individual one-pound boxes of cashews, raisins, caramels, and chocolates. a major attraction of the candy counter is that all candies are made fresh at the counter. however, storage space for supplies and ingredients is limited. bins are available that can hold the amounts shown in the following table:

product each day. assume that demand of the candies is such that regardless of candy mix all candy will be sold every day. formulate the problem in order to maximize profit. the profit per box for the

variables clearly defined and all constraints clearly defined. 2) solve the formulation in solver and save the sensitivity report. 3) using sensitivity analysis: if you had $6.00 to spend and it cost $1.50 to increase capacity of cashews by one pound, $1.20 to increase capacity of raisins by one pound, $0.60 to increase capacity of caramels by one pound, and $0.30 to increase capacity of chocolates by one pound; how would you spend the $6.00 to maximize your return and what would be your net return? explain your answer. deliverable 2 (10 points): the chocolate maker is considering broadening his candy selection by adding two candies to his selection: the regular candy with marshmallow topping and the deluxe candy with marshmallow topping. he will add 0.05 pounds of marshmallow topping on one pound of each of the regular or deluxe candies to make the new candies. since he is not sure whether to add these candies he will not require a certain amount be made per day. he has space to add 10 pounds of marshmallow per day and the profit for the marshmallow regular is $1.00/pound and the marshmallow deluxe is $1.05/pound. also, the production of the marshmallow regular cannot be greater than the total production of the regular and deluxe candies. formulate the problem in order to maximize profit. requirements: 1) give a typed formulation with decision variables
