Objectives and Research Themes

This thesis investigates the financial and operational consequences of severe production disruptions within a pharmaceutical supply chain, specifically focusing on a high-margin product over its market cycle. The core research objective is to quantify these risks using Monte Carlo simulation and to evaluate how different inventory policies and risk management strategies—tailored to various risk preferences—can mitigate potential performance losses and protect against downside risks.

• Quantification of operational and financial performance impacts under stochastic production disruptions.
• Evaluation of safety stock policies as a proactive mitigation strategy against supply chain volatility.
• Integration of risk-averse decision-making models into supply chain inventory management.
• Simulation of long-term demand consequences resulting from service level degradation during disruption periods.
• Scenario-based sensitivity analysis to identify robust inventory strategies across varying disruption intensities.

Frequently Asked Questions

What is the primary focus of this research?

This thesis examines the financial and operational impact of severe production disruptions on a high-margin pharmaceutical product over its entire market cycle.

Which central topics are addressed in the study?

Key topics include supply chain vulnerability, the importance of inventory buffers, stochastic disruption modeling, and the trade-off between lean operations and risk mitigation.

What is the main research objective?

The goal is to quantify financial and operational risk exposure and to identify optimal inventory strategies that protect the firm against severe disruption scenarios.

Which methodology is employed to reach the findings?

The study utilizes a periodic-review inventory model combined with Monte Carlo simulation (MCS) to analyze performance under varying disruption probabilities and durations.

What does the main body cover?

It covers a detailed case study of an aseptic pharmaceutical production process, the development of a simulation model, scenario-based analysis, and the testing of inventory-based mitigation tactics.

Which keywords characterize this thesis?

The work is characterized by terms such as Supply Chain Disruptions, Monte Carlo Simulation, Inventory Policy, Value at Risk, and Risk Mitigation.

How does the pharmaceutical production process contribute to the risk profile of the case study?

The process involves strict aseptic requirements where positive "media-fill" test results lead to significant production halts, causing immediate production loss and long-term negative effects on demand due to customer switching.

Does a single optimal inventory policy exist for all situations?

No, the study concludes that there is no one-size-fits-all inventory policy; the optimal strategy is highly dependent on specific disruption parameters, product characteristics, and the risk preference of the decision-maker.

Why are conservative inventory policies often advantageous for the studied product?

Given the high contribution margin of the product relative to inventory holding costs, conservative policies (higher safety stocks) effectively mitigate downside risks with minimal negative impact on expected profits.
