Introduction
The final exam for the IT 608 - Managerial Decision Modeling course encompasses multiple complex cases requiring analytical evaluation to inform managerial decisions. This assessment evaluates skills in project scheduling, cost minimization, medical decision analysis, service system design, and forecasting, each necessitating rigorous application of decision modeling principles. The exam comprises four case studies, each with specific questions aimed at fostering critical thinking and quantitative analysis.
Case 1: Project Scheduling and Cost Optimization at Bay Community Hospital
The first case involves planning the introduction of a new diagnostic procedure in a hospital setting. Dr. Windsor has outlined several activities with their respective durations and dependencies. The core challenge is to determine the shortest possible project completion time by considering activity durations, potential schedule compressions, and associated costs.
Analysis Approach
Constructing a project network diagram and performing critical path analysis are essential. The expected project duration is calculated using the activity durations. To find the minimum completion time, a critical path method (CPM) analysis is performed, considering opportunities to reduce activity durations through premium payments. The analysis involves evaluating the trade-offs between schedule compression and costs, including express shipping, overtime work, and activity acceleration costs. A cost schedule is developed to identify the lowest total expense for the shortest feasible project duration.
Expected Results
- The project’s earliest completion time under standard durations.
- The absolute shortest project duration considering schedule compressions.
- The cost-minimized schedule aligned with the shortest project duration, incorporating accelerated activities and their costs.
Case 2: Medical Decision Analysis for Ruth Jones’ Heart Surgery
This case involves a decision-making scenario regarding whether Ruth Jones should undergo heart bypass surgery. Survival probabilities with and without surgery are provided over various time horizons.
Analysis Approach
Applying decision theory and survival analysis principles, the expected utility or survival probabilities are compared. This involves calculating expected survivorship both with and without surgical intervention, considering associated risks such as surgical mortality and post-operative survival rates. A risk-benefit analysis informed by probabilistic outcomes guides whether surgery is advisable.
Expected Results
- A comparative assessment of survival odds with and without surgery.
- A recommendation based on expected survival probabilities, quality of life implications, and patient preferences.
Case 3: Service System Design at Pantry Shopper Supermarket
The third case examines optimal checkout system design to improve customer service efficiency, considering customer arrival rates and transaction times.
Analysis Approach
Constructing queue models, such as M/M/s or M/G/1, will help determine the optimal number of checkout lanes. Service times for different customer segments are analyzed, and simulation or queuing formulas forecast wait times and service efficiency. Design considerations include balancing cost of additional registers against customer service levels.
Expected Results
- Optimal number of checkout lanes to minimize wait time and space.
- Estimation of customer wait times and service capacity at peak hours.
- Recommendations for technological improvements, such as universal price code readers.
Case 4: Attendance Forecasting at Akron Zoological Park
The final case involves forecasting attendance and revenue using regression and considering external factors influencing zoo visitation.
Analysis Approach
Simple linear regression analysis is conducted using historical attendance and pricing data. Additional factors such as weather, marketing efforts, and seasonal trends should be incorporated into a multiple regression model to improve forecast accuracy.
Expected Results
- Validation of whether linear regression is suitable for attendance prediction.
- Identification of significant variables influencing attendance.
- Accurate forecasts for 2006 and 2007, enabling strategic financial planning.
Conclusion
The comprehensive analysis across these cases involves applying core decision modeling tools such as critical path analysis, probability assessment, queuing theory, and regression analysis. These techniques provide quantitative support for managerial decisions regarding project schedules, healthcare interventions, operational efficiency, and revenue forecasting. Success in this exam demonstrates the ability to integrate theoretical models with practical applications to enhance decision-making efficiency in diverse organizational contexts.
