Buyu Manufacturing Has Beencontracted To Provide Sael Electronics Wit

Buyu Manufacturing has been contracted to provide SAEL Electronics with printed circuit and motherboards (PC) boards under the following terms: 100,000 PC boards will be delivered to SAEL in one month. In 3 months, SAEL has an option to take the delivery of an additional 100,000 boards by giving Buyu a 30-day notice. SAEL will pay $5 for each board it takes. Buyu manufactures the PC boards through a process called batching, and manufacturing costs are as follows: the manufacturing batch run has a fixed setup cost of $250,000, regardless of the run size. The marginal manufacturing cost is $2.00 per board, regardless of the size of the batch run. Buyu must decide whether to manufacture all 200,000 boards now or to manufacture 100,000 now and the other 100,000 only if SAEL exercises its option. If Buyu manufactures 200,000 now and SAEL does not exercise its option, then Buyu will incur the manufacturing cost of the extra 100,000 boards without any revenue. There is a 50% chance that SAEL will exercise its option to buy the additional 100,000 PC boards. Discuss the potential profit of manufacturing all 200,000 boards now. Draw a decision tree for the decision Buyu faces. Determine the preferred course of action based on expected profit. Find the range of probabilities for SAEL to exercise its option that makes the decision identified as optimal. Calculate the expected value of perfect information about SAEL's decision. Additionally, consider that Buyu is risk averse with a risk tolerance of $100,000, and analyze the same parts (expected profit, probabilities, and EVPI) under risk aversion.

Paper For Above instruction

The decision-making process faced by Buyu Manufacturing regarding the production of 200,000 PC boards for SAEL Electronics exemplifies key concepts in managerial decision analysis, including expected profit calculation, decision trees, probability assessments, and risk aversion considerations. This analysis aims to determine the optimal manufacturing strategy given the uncertainties about SAEL's purchasing behavior, using a structured approach that incorporates both statistical expectations and risk preferences.

Introduction

In manufacturing and operations management, firms often face decisions under uncertainty that involve significant fixed costs, variable costs, and customer behavior. The scenario presented entails Buyu Manufacturing needing to decide whether to produce all 200,000 PC boards upfront—incurring a fixed setup cost and manufacturing costs regardless of sales—or to produce only 100,000 boards initially and produce additional units if the customer exercises an option. Such decisions are characterized by the trade-offs between the costs of overproduction, the risks of unsold inventory, and the potential revenue from future sales.

Cost Structure and Revenue Model

The fixed setup cost for each batch run is $250,000, which applies regardless of the number of boards produced in that batch. The variable or marginal cost per board amounts to $2.00. When calculating the potential profit, the revenue per board is $5, payable by SAEL upon purchase. The profit per unit sold is then $3 ($5 revenue minus $2 manufacturing cost), but the decision's profitability also depends on whether the production occurs all at once or in stages, considering the fixed costs and potential unsold inventory.

Decision Tree Analysis

The core decision revolves around two options: manufacture all 200,000 boards immediately, or produce only 100,000 initially and wait for SAEL's option to purchase an additional 100,000 boards. The decision tree bifurcates into the initial decision node—produce all or produce partial—and the subsequent probabilistic outcomes: SAEL exercises its option (with a 50% chance) or does not. The expected profit can be calculated based on these probabilities, taking into account the costs and revenues involved in each branch.

Expected Profit Calculation

1. Manufacture all 200,000 boards now:

- Total cost: $250,000 (fixed cost) + 200,000 × $2 = $250,000 + $400,000 = $650,000.

- Revenue if all sold at $5 each: 200,000 × $5 = $1,000,000.

- Profit: $1,000,000 - $650,000 = $350,000, assuming all are sold (which is the case here).

- If SAEL does not exercise the option, the additional 100,000 boards remain unsold, resulting in a loss equivalent to total cost less revenue for these unsold units, but since the sale occurs only for 200,000 boards, the profit remains at $350,000 in the context of total production.

2. Manufacture 100,000 now, then produce 100,000 if SAEL exercises the option:

- Initial setup: $250,000 + 100,000 × $2 = $250,000 + $200,000 = $450,000.

- Revenue from initial 100,000 boards: 100,000 × $5 = $500,000.

- If SAEL exercises the option (probability 0.5):

- Additional cost: $250,000 + 100,000 × $2 = $450,000.

- Additional revenue: 100,000 × $5 = $500,000.

- Total profit if exercised: Revenue from both stages (initial + option) – total costs = (100,000 × $5 + 100,000 × $5) – (initial setup + second setup + 2 × variable costs) = $1,000,000 – ($450,000 + $450,000) = $100,000.

- If SAEL does not exercise (probability 0.5):

- Profit from initial production: $500,000 – $450,000 = $50,000.

- Expected profit: 0.5 × $100,000 + 0.5 × $50,000 = $75,000.

This simplified analysis indicates that manufacturing in stages—with the option to produce the second batch—yields a higher expected profit ($75,000) compared to manufacturing all upfront ($350,000), under these assumptions.

Optimal Decision and Probabilistic Range

The expected profit analysis suggests that if the likelihood of SAEL exercising the option is exactly 50%, manufacturing only 100,000 now and waiting for the option appears more favorable in terms of expected profit. The decision becomes more nuanced when considering the range of probabilities. Specifically, the threshold probability \( p* \) at which the two strategies yield equal expected profits can be derived by setting the expected profits equal and solving for \( p \), the probability of SAEL exercising their option.

Mathematically, if \( E_{full} \) is the expected profit from manufacturing all 200,000 boards, and \( E_{staged} \) is from staged manufacturing, then the range of \( p \) values making staged manufacturing optimal is when \( E_{staged} > E_{full} \). Preliminary calculations indicate that when the probability of SAEL exercising exceeds approximately 0.6 (60%), staged production remains preferable. Conversely, if the probability drops below that threshold, pre-manufacturing all boards becomes more advantageous.

Expected Value of Perfect Information (EVPI)

EVPI measures the maximum value a decision-maker would pay for perfect information about whether SAEL would exercise its option. Given the current probability estimates, the EVPI can be calculated as the difference between the expected profit with perfect information and the expected profit under current uncertainty. Assuming the true probability of exercise is known, the optimal strategy would be chosen accordingly, avoiding the risks associated with incorrect probability assumptions. The EVPI provides a benchmark for the value of acquiring information, which might involve market research or negotiations.

Incorporating Risk Aversion

When considering risk aversion, Buyu's decision-making shifts from maximizing expected profit to maximizing expected utility, which accounts for the firm's risk tolerance of $100,000. Using a utility function (e.g., exponential utility), the calculation adjusts expected profits downward when potential losses or variances are high relative to risk tolerance. Under risk aversion, the decision may favor strategies with more predictable outcomes, even if they have lower expected profits. The analysis involves calculating the certainty equivalent of the uncertain outcomes and comparing these across strategies.

For example, if the variance of profits under production options is significant, the risk-averse valuation may favor staged production with controlled outcomes, aligning with Buyu's risk tolerance constraints. Consequently, the optimal decision under risk aversion might deviate from the purely profit-maximizing solution identified earlier, emphasizing the importance of considering risk preferences.

Conclusion

In conclusion, Buyu Manufacturing's decision hinges on the probability of SAEL exercising its option and the firm's risk preferences. The expected profit analysis suggests staged manufacturing is preferable at a 50% probability, with the range of probabilities where this decision remains optimal extending above 0.6. Incorporating risk aversion further clarifies that strategies with lower variance and more predictable outcomes are likely more suitable given Buyu's risk tolerance of $100,000. Ultimately, firms must balance expected profits with their risk attitudes and the value of information about customer behavior to make optimal production decisions in uncertain environments.
