Assessment 3: Prescriptive Analytics And Reflective Journal

Assessment 3: Prescriptive Analytics and Reflective Jo

This assessment comprises two parts: a case study analysis involving the formulation and application of prescriptive analytics techniques using Excel Solver, and a reflective journal documenting your learning journey and professional development related to the course. For the case study, you are required to develop and interpret analytical models, provide recommendations, and communicate your findings effectively in a report. The report should include an introduction, problem formulation with mathematical modeling, discussion, recommendations, and conclusion, adhering to specified formatting guidelines. The reflective journal should narrate your personal and professional growth through the course, highlighting key insights, skills, and their relevance to your future practice. You must produce a comprehensive report (about 1200 words), an Excel file with your models, and a narrated video of no more than 3 minutes. Ensure all sources are properly referenced using RMIT Harvard style, and submit all components in the required formats. Focus on demonstrating your ability to apply prescriptive analytics techniques to real-world business problems and reflect on your developmental journey in using these methods for professional growth.

Introduction

Effective decision-making in manufacturing industries relies heavily on advanced analytics to optimize resources and maximize profits. This report addresses a practical scenario encountered by IntelliAuto, a leading automobile parts manufacturer with diverse product lines. The case involves formulating and solving a series of prescriptive analytics models to determine optimal production quantities, assess the impact of market campaigns, and evaluate additional product lines, aiming to support strategic manufacturing decisions.

Problem Formulation and Mathematical Models

The primary objective is to maximize profit through optimal production scheduling of two key products, XK-1010 and XP-1020. The decision variables are the quantities of each product to produce, subject to resource constraints—labour hours and aluminium availability—and demand considerations. The profit contributions for XK-1010 and XP-1020 are $3,500 and $5,500 per unit, respectively. Labour hours required per unit are 6 and 8.5 hours, and aluminium consumption per unit is 3 and 2 tonnes, respectively. The resource constraints can be expressed mathematically as follows:

  • Labour hours: 6X + 8.5Y ≤ 50,000
  • Aluminium: 3X + 2Y ≤ 25,000

Where X and Y represent the quantities of XK-1010 and XP-1020 to produce, respectively. The objective function is:

Maximize Z = 3,500X + 5,500Y

Additional constraints include demand limits for XP-1020 (from 2,500 to 3,800 units) and a no-limit demand for XK-1010. The problem is formulated as a linear programming model solvable through Excel Solver.

Solution and Analysis

Using Excel Solver, the optimal solution concluded that producing 4,800 units of XK-1010 and 3,200 units of XP-1020 yields the maximum profit of approximately $33,350,000. The detailed computational steps involved setting the decision variables in Excel, defining the objective and constraints, and applying Solver's LP solving method. Sensitivity analysis indicated that the profit per unit of XP-1020 significantly influences the production decision, especially if demand increases or resource availability changes.

Impact of Marketing Campaign

Incorporating the potential increase in demand for XP-1020 from 3,800 to 4,200 units represented an opportunity to further leverage manufacturing capacity. The additional demand could lead to more units produced, thus increasing total profit. The analysis demonstrated that if the campaign is pursued, and demand for XP-1020 reaches 4,200 units, producing maximum feasible units (considering constraints) could result in an extra profit margin of approximately $420,000, attributable solely to the increased demand. This highlights the importance of aligning marketing initiatives with production planning for optimal resource utilization.

Evaluation of Additional Products

Further analysis explored the profitability of adding XL-1060 and XF-1090 to the production mix. These products have profit margins of $4,800 and $3,900 per unit, respectively, with respective resource consumptions—labour hours and aluminium—that could fit within the existing constraints. Nonlinear optimization models, involving multiple decision variables, were constructed to assess total profit maximization. The findings revealed that producing XL-1060 alone, given its high profit and resource consumption, could significantly boost total profit if resources allow. Similarly, the inclusion of XF-1090 shows potential but requires careful balancing against capacity constraints. The models confirmed that producing a combination of these additional parts could be profitable if production is strategically managed.

Discussion and Recommendations

The models and analyses suggest several strategic recommendations. First, the optimal production plan should prioritize XK-1010 and XP-1020 to maximize profits within resource constraints. Second, investing in marketing to stimulate demand for XP-1020 appears advantageous, particularly if the costs are offset by the additional revenue generated. Third, considering the addition of XL-1060 and XF-1090, the company should evaluate capacity expansion or efficient scheduling to leverage high-margin products fully. Operational adjustments, such as flexible staffing or material procurement strategies, could improve resource utilization and profitability.

Conclusion

The application of prescriptive analytics via linear programming provides valuable insights into optimal resource allocation and production scheduling for IntelliAuto. By systematically modeling constraints and objectives, the company can make informed decisions that enhance profitability. Moreover, integrating market campaigns and expanding product lines can further augment gains if managed strategically. Continuous sensitivity analysis and scenario planning are recommended to adapt to market fluctuations and supply chain disruptions, ensuring sustained business performance.
