Have you learned about the simplex method? Are you supposed to use some algorithm other than brute force (checking each intersection)?
I keep having my task rejected because it says I am not showing work. I don't understand what kind of work they want me to show and because we use TaskStream to submit my paper, There isn't anyone to ask either. This is what they say:
Comments on this criterion: No revision is provided to show the work.
The optimum combination (4.5, 3) is determined but the work shown is not sufficient. Please show the work done to determine the candidate points.
This is the task and what I submitted:
C. Determine how many cases each of Brand X and of Brand Y you recommend should be produced during each production period for optimum production if Company A wants to generate the greatest amount of profit, showing all of your work.
C.
The vertices are:
P(0, 0) = $0 + $0 = $0 profit
P(0, 6) = $0 + $180 = $180 profit
P(2.5, 5) = $100 + $150 = $250 profit
P(4.5, 3) = $180 + $90 = $270 profit
P(6, 0) = $240 + $0 = $240 profit
P = ($40*4.5) + ($30*3) = $270
I would reccomend that during optimum production, the company produce 4.5 cases of brand X and 3 cases of brand Y.
Any help is greatly appreciated.
Just brute force. Here is the whole question it my help to see the whole problem.
Graphical models enable a manager to visualize the objective function (profit line), constraints, and possible solutions to a given problem, and to make more informed decisions based on that information.
Given:
Company A produces and sells a popular pet food product packaged under two brand names, with formulas that contain different proportions of the same ingredients. Company A made this decision so that their national branded product would be differentiated from the private label product. Some product is sold under the company’s nationally advertised brand (Brand X), while the re-proportioned formula is packaged under a private label (Brand Y) and is sold to chain stores.
Because of volume discounts and other stipulations in the sales agreements, the contribution to profit from the Brand Y private label product is only $30 per case compared to $40 per case for product sold to distributors under the company’s Brand X national brand.
An ample supply is available of most of the pet food ingredients; however, three additives are in limited supply. The tight supply of nutrient C (one of several nutrient additives), a flavor additive, and a color additive all limit production of both Brand X and Brand Y.
The formula for a case of Brand X calls for 4 units of nutrient C, 12 units of flavor additive, and 6 units of color additive. The Brand Y formula per case requires 4 units of nutrient C, 6 units of flavor additive, and 15 units of color additive. The supply of the three ingredients for each production period is limited to 30 units of nutrient C, 72 units of flavor additive, and 90 units of color additive.
Task:
A. Determine the equations for each of the three constraints that are plotted on the attached “Graph 1,” showing all work necessary to arrive at the equations.
1. Identify each constraint as a minimum or a maximum constraint.
B. Determine the total contribution to profit if the company produces a combination of cases of Brand X and Brand Y that lies on the purple objective function (profit line) as it is plotted on the attached “Graph 1.”
C. Determine how many cases each of Brand X and of Brand Y you recommend should be produced during each production period for optimum production if Company A wants to generate the greatest amount of profit, showing all of your work.
D. Determine the total contribution to profit that would be generated by the production level you recommend in part C, showing all of your work.
In your submission above, you followed each P line by a sum of two prices, but did you include a calculation of multiplying the points by the prices? Perhaps they really want all of the details. In your conclusion include the point, the price at this point, and perhaps the calculation again. Beyond this, I cannot surmise what other details they require given the method and the work you already did.
