1.1. Background and Motivation
1.2. Related Works
1.3. Research Gap, Contributions and Paper Structure
- Studies on predictive maintenance and AHMS focus on large airlines and high-resource environments (e.g., Airbus Skywise and Boeing AHM) but do not consider the financial and technical constraints faced by small carriers.
- Research on data exchange protocols in aviation (e.g., ATA Spec 2000 and iSpec 2200) provides structured frameworks but does not offer implementation strategies that accommodate the heterogeneous IT capabilities of small aviation service providers.
- Literature on digital platforms and cloud-based aviation solutions highlights the potential of shared services models but lacks an in-depth exploration of how these platforms can be optimized for cost-efficiency, scalability, and regulatory compliance in small airline operations.
- Identification of the challenges faced by small airlines in accessing reliable and cost-effective technical support, emphasizing the need for an ATSaaS framework.
- Development of a structured ATSaaS model, analyzing both centralized and decentralized architectures for data conversion and integration, including their respective advantages and limitations.
- Mathematical modeling and life cycle cost analysis, evaluating the trade-offs between initial investments, operational costs, and long-term scalability of centralized vs. decentralized ATSaaS architectures.
- Introduction of a multi-criteria decision-making framework that considers cost, performance, security, scalability, and sustainability, providing a structured approach for selecting the optimal ATSaaS architecture.
- Addressing real-world implementation challenges, including data standardization, cybersecurity risks, and regulatory compliance, offering practical strategies for integrating ATSaaS into small airline operations.
2. Alternative ATSaaS Platform Architectures
2.1. Centralized ATSaaS Platform Architecture
- By centralizing the data conversion process, the ATSaaS provider can ensure consistency in data handling and processing. This approach allows for uniform application of data standards and protocols, reducing the risk of errors and discrepancies.
- Client organizations do not need to modify their existing systems. They can continue to operate using their local information systems without the need to invest in new technology or training, making the transition to ATSaaS smoother and more cost-effective.
- A centralized system can be more easily scaled to accommodate additional clients and data sources. The centralized approach allows for a single point of upgrade and maintenance, simplifying system management.
- Centralizing data processing can enhance security by reducing the number of entry points that need to be secured. The ATSaaS provider can implement robust security measures at the central hub to protect sensitive data.
- A centralized system introduces a single point of failure. If the central hub experiences a technical issue or security breach, it can impact all client organizations connected to the ATSaaS platform.
- Collecting and converting data at a central location can introduce latency, particularly if the client organizations are geographically dispersed. This can affect the timeliness of data availability for decision making.
- Setting up and maintaining a centralized data conversion hub requires significant investment in infrastructure and resources. The provider must ensure sufficient computational power and storage capacity to handle large volumes of data.
2.2. Decentralized ATSaaS Platform Architecture
- By decentralizing the data conversion process, the risk is distributed across multiple organizations. A failure in one organization’s system does not affect the entire ATSaaS network.
- Local data conversion can facilitate real-time data transmission and availability, as there is no need for data to travel to a central hub for processing.
- Each organization can tailor the data conversion process to meet its specific needs and requirements, allowing for greater flexibility and customization.
- Decentralizing data conversion reduces the load on the central ATSaaS infrastructure, potentially lowering the provider’s operational costs and improving system performance.
- Each organization must implement and maintain its data conversion mechanisms, which can be complex and resource intensive. This approach requires significant coordination and standardization efforts.
- Decentralized data conversion can lead to inconsistencies in data quality and format, especially if organizations do not adhere strictly to the standardized protocols. To prevent such issues, it will be necessary to establish clear standards and requirements for input data. However, this will significantly increase the complexity of system development and make integration more challenging for clients. Decentralized data conversion, without strict adherence to standardized protocols, risks inconsistencies in data quality and format.
- Ensuring the security of data during transmission from multiple decentralized locations can be challenging. Each organization must implement robust security measures, increasing the overall complexity of the system.
- While decentralized systems may reduce long-term operational costs, the initial setup costs for each organization to implement the necessary data conversion infrastructure can be high.
2.3. Data Conversion in the Context of ATSaaS
2.3.1. Data Conversion Approaches in ATSaaS
- Identifying the relationships between the source data fields and the target data fields and defining the rules for transforming the data from one format to another.
- Retrieving the relevant data from the source system, which may involve querying databases, parsing files, or accessing APIs.
- Applying the defined mapping rules to convert the extracted data into the desired format. This may include tasks such as data type conversions, data normalization, data aggregation, or data splitting.
- Inserting the transformed data into the target system, ensuring that it adheres to the required format and constraints.
- Insufficient volume and completeness of data that fails to meet the platform’s minimum requirements for the specified data objects.

- The decentralized architecture has lower initial costs since each organization manages its own system.
- Operational costs grow super-linearly due to scalability requirements across multiple independent systems.
