Subject: Decision Analysis for Business Scenario
Introduction to the Business Scenario
Our delivery services business has been experiencing steady growth, leading to an
increased demand for faster and more efficient deliveries. To meet this demand,
we must decide on the best strategy to expand our fleet. The three possible
alternatives under consideration are purchasing new delivery vehicles, leasing
vehicles, or partnering with third-party drivers. The decision must account for
various external factors, including fuel price fluctuations, demand stability, and
competition growth, which we categorize as the states of nature. Each alternative
presents unique advantages and challenges, and our goal is to select the most
viable option using a structured decision-making approach.
Alternatives and States of Nature
The three alternatives for fleet expansion were chosen based on their cost
implications, operational efficiency, and…
Golden Ratio search Method
f(x) = 2x^3 - 3x^2 - 12x + 1
Golden ratio search rules 1.If f(x) < f(x2):
1. Eliminate all x values less than x2
2. X2 becomes the new a
3. x, becomes the new x2
4. no change in b
If f(x) > f(x2):
1. Eliminate all x values greater than x
2. x, becomes the new b
3. x2 becomes the new x
4. no change in aquesion=Narrow the interval in which the minimizer of the function f is located using the golden search method, starting with the initial interval (0,6], until its width is less than 2. Then, accept the midpoint of this interval as an approximate value of the minimizer of the function fand determine it. (ф=0.62)According to the question above, fill in the table below using the algorithm until the appropriate place.please write every step by step in a verry comprehensive way

The fixed cost to produce the doll is $100,000. The variable cost, which includes material, labor, and shipping costs, is $31 per doll. During the holiday selling season, FTC will sell the dolls for $39 each. If FTC overproduces the dolls, the excess dolls will be sold in January through a distributor who has agreed to pay FTC $10 per doll. Demand for new toys during the holiday selling season is extremely uncertain. Forecasts are for expected sales of 60,000 dolls with a standard deviation of 15,000. The normal probability distribution is assumed to be a good description of the demand.
