This proof-of-concept MES application models traceability across a manufacturing and assembly workflow. It assigns a UUID to each component, uses role-based access control to separate responsibilities, applies FIFO-based inventory allocation, and records component-to-assembly relationships for later audit.

The application was developed around a representative UAV manufacturing scenario and tested as a software PoC. It has not been deployed in a production environment.

 Sectoral Scalability: Structured directly using rigorous Aerospace compliance benchmarks, this architecture possesses the inherent flexibility to be directly scaled horizontally into automotive, heavy industry, and generalized industrial machinery production bands without necessitating fundamental architectural alterations.

Project Portfolio

Current Situation and Problem

Context: The scenario below uses publicly known UAV platform names as representative examples. It does not reflect any real manufacturer’s process, data or configuration. The integration environments of autonomous platform products (TB2, AKINCI, etc.) within the defense sector mandate exceptionally strict traceability compliance regulations. Every individual physical hardware unit populating the factory grid constitutes an obligatory audit record—demanding absolute clarity regarding which approved procurement batch it originated from, which specific operator configured it at which station, and ultimately, which primary airframe it was deployed into. 

Critical Issues: Extruded in the absence of a synchronized, digitally role-bound administrative control mechanism, the statistical probability of component mismatching or structural clashes across disparate platforms escalates. Relying solely on manual worksheets and disconnected ERP peripheral data matrices (often completely deviating from true FIFO constraints) liquidates any capability to execute conclusive backward root-cause analyses during critical audits.

Solution Architecture and Execution

Architectural Approach: A full 3-tier API architecture was mapped out, relying on role-based security boundaries and deterministic inventory allocations to effectively neutralize data-management risks.

Applied Methodology

Hardware (UUID) Serialization Process

Every fully manufactured physical component is ingested into the database environment formatted exclusively as a UUID. This explicit parameter logs production execution times, specific batch typologies, and precise assembly line trajectory assignments ensuring minimal procedural margin of error:

class Part(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    part_type = models.ForeignKey(PartType, on_delete=models.PROTECT)
    produced_by = models.ForeignKey(Employee, on_delete=models.PROTECT)
    production_date = models.DateTimeField(auto_now_add=True)
    aircraft = models.ForeignKey(Aircraft, null=True, blank=True, on_delete=models.SET_NULL)

Role-Based Access Control (RBAC) Node

Three separated access roles were defined within the “Production” sector to physically enforce reliable duty segregation paradigms:

Automated Compatibility Isolation

Configuring a fail-safe framework, the network blocks aircraft assembly progressions if human data-input matrices or invalid API requests command conflicting hardware platforms:

def validate_assembly(aircraft_type, part):
    """Halts localized structural crossovers between non-compatible platforms"""
    if part.part_type.platform != aircraft_type.platform:
        raise ValidationError(
            f"{part.part_type.name} part cannot be integrated into {aircraft_type.name} hardware."
        )

Deterministic FIFO (First-In-First-Out)

overriding serial production degradation factors, the absolute oldest raw hardware components injected sequentially into the shop floor are prioritized for assembly querying logic:

def allocate_part(part_type, aircraft):
    """Allocate the oldest historical component directly to open assembly cycles"""
    available_part = Part.objects.filter(
        part_type=part_type,
        aircraft__isnull=True,
        is_deleted=False
    ).order_by('production_date').first()
    
    if available_part:
        available_part.aircraft = aircraft
        available_part.save()
        return available_part
    raise StockError("Scheduled integration requirement is functionally out of stock")

Soft-Delete Protocols for Audit Logging

Regardless of whether operational components trigger critical revision recalls or are definitively designated as physical scrap assets, items are structurally preserved and exclusively marked (is_deleted) securing uncompromising standard audit compliance logs.

Results and Operational Gains

PoC Results — observed in functional testing of the application.

API Integration Architecture (ERP Readiness)

Operating OpenAPI 3.0 frameworks, OpenAPI documentation was generated as a basis for future ERP integration with enterprise systems such as SAP or Oracle. No SAP or Oracle integration has been implemented.

GET    /api/parts/                 # Index all available active hardware within factory bounds
POST   /api/parts/                 # Declare standard new ingress component parameters
DELETE /api/parts/{id}/            # Classify component strictly as physical scrap (soft-delete record)

GET    /api/aircraft/              # Call active status updates reflecting complete main assembly lines
POST   /api/aircraft/              # Initialize new assembly framework matrix directly onto the line
GET    /api/inventory/stock-levels # Provide real-time operational hardware stock queries (Live Count)
