5.3.12.2.1 Directives and General Conditions

This subject presents a summary of the standards and framework conditions derived from the »Logistic Support Specification.

It describes the general logistic outline concept to be applied to the system. This includes, e.g., work-sharing logistics, operator model, leasing model or cooperative logistics. The specific conditions and configurations of the selected logistic outline concept, e.g. duration of contract, warranty conditions, guaranteed support, legal or other restrictions, will be described.

5.3.12.2.2 System Architecture

This subject provides a summary of the system architecture as seen from a logistic point of view. It specifies the designation and part number (identification number), the number of elements within the system and the planned total number for every element of the »System Architecture. Indicators, like reliability (Mean Time Between Failure) and maintainability (Mean Time To Repair) shall be provided (see also »Logistic Calculations and Analyses ). It should be ensured that the presented system architecture corresponds to the system architecture presented in the work product »System Architecture.

Exemplary Product Content

The following data elements should be provided for every element of the system architecture:

• Designation
• Part number (unambiguous identification number, not serial number)
• Manufacturer/supplier or person in charge of logistic support
• Number of the respective element per system or per higher component
• Total number of systems, segments, hardware/software units to be delivered
• Reliability (MTBF)
• Maintainability (MTTR)

5.3.12.2.3 Logistic Support Alternatives and Comparative Evaluation

This subject develops and evaluates several logistic support alternatives. The required logistic resources, organizational provisions, infrastructure measures and logistic indicators, like availability, will be described for every alternative. The decisive results of the alternatives - fulfillment of the requirements with maximum availability and minimum life cycle costs - shall be compared.

Exemplary Product Content

In order to fulfill the requirements, particularly with regard to availability, logistic support alternatives shall be developed. For every alternative, the following characteristics shall be presented in detail:

• Maintenance (definition of easily replaceable units, servicing, maintenance, repair)
• Technical availability (reliability, maintainability, repairability, testability)
• Logistic resources (standard/special tools, measuring and test equipment, alternate equipment and spare parts, documentation, training, personnel and qualification, service organization, transport logistics and storage, disposal and waste management)
• Infrastructure measures
• Organizational provisions
• External logistic support interfaces (integration of logistic resources into the system, e.g., IETD into system software, interfaces to logistic information systems)

5.3.12.2.4 Logistic Support Design

One of the developed alternatives will be selected, and the selection will be justified. This subject develops and describes the selected solution in detail.

This subject specifies particularly type, number and structuring of the required logistic support documentation. In case of complex systems, the structuring depends on the »System Decomposition. Elements of the logistic support documentation will be allocated to system elements.

This subject also lists additional support to be provided by the supplier, e.g., delivery of spare parts, instructions, local support or technical logistic support.

Exemplary Product Content

In case of complex systems, the structuring of resources depends on the decomposition (structure) of the system. The additional structuring of logistic support may be based on the following elements :

• Documentation
• Training
• Standard/special tools, measuring and test equipment
• Spare parts

Depending on the use of the system during its life cycle and the employed personnel, the elements may be structured further as follows:

• Control,
• administration,
• operation,
• maintenance,
• repair and
• supply.

The logistic support for selected resources could - for example - be structured as follows:

In-service use, maintenance and repair documentation:

• level: "manual series" (e.g. description, operation and diagnosis)
• level: "manual" (e.g. diagnostic manual)
• level: "volume" (e.g. service level I or service level II)
• level: "chapter" or "data process module" (e.g. fault finding or corrective action)

Training documents:

• level: training document, "system training" (e.g. communication system)
• level: training document, "equipment training" (e.g. communication equipment)
• level: training document, "training activity" (e.g. operation)
• level: training document, "training hour or training day" (e.g. activation)

Standard/special tools, measuring and test equipment:

• level: "test bench" (e.g. radar system)
• level: "test function" (e.g. check for emission control)
• level: "test equipment" (e.g. protective clothing, measuring device)
• level: "test unit" (e.g. antenna, sensor)

Infrastructure:

• level: "site" (e.g. consumer goods)
• level: "hangar" (e.g. production hangar)
• level: "hangar area or room" (e.g. production of product A)
• level: furnishings (e.g. furniture or utility connections)

The allocation of logistic resources to different life cycle phases shall be indicated, with individual resources possibly being allocated to several phases.

5.3.12.2.5 Logistic Resources Cooperation

This subject describes the cooperation of system, »Enabling Systems and logistic elements. It presents, e.g, the deployment of resources, process chains, sequences of operations and procedures (Supply Chain Management).

The subject also describes organizational features, e.g., points of contact, liaison, responsibilities and integration into existing or newly to be developed organizational and IT structures.

It must be possible to implement the logistic support by using this description.

5.3.12.2.6 Establishment of Logistic Supportability and Introduction into Service

The establishment of logistic supportability and introduction into service shall be described in detail. The establishment of logistic supportability includes all measures required for providing and integrating the logistic support for the system. Logistic supportability is ensured when all necessary »Enabling Systems, spare parts and additional logistic resources are available.

The introduction into service includes the installation and activation of the system. Test or parallel operations shall be provided as required. For this purpose, the required logistic support and the training of the acquirer shall be ensured.

Exemplary Product Content

The logistic supportability of a system is ensured when

• all facilities, standard and special tools for in-service use, maintenance and repair are available,
• spare parts requirements are fulfilled,
• the follow-on spare parts supply is ensured,
• the personnel required for operation, maintenance and repair, and spare parts supply is available and trained adequately,
• the documentation for in-service use, maintenance and repair has been delivered to the acquirer, and
• in-service support, maintenance and repair are ensured.

These subjects shall be taken into account for the establishment of logistic supportability.

5.3.12.2.7 Disposal

This subject describes all measures required for the »Disposal of a system. The disposal comprises the deactivation and waste management.

The deactivation is a temporary storage of a system. It is intended to remove a system which is no longer in use from its operational environment. Depending on the further use, the system will be preserved and maintained before or during the deactivation in order to permit a reactivation at a later date.

Waste management deals with the final removal of a system, which can no longer be reactivated. Waste management is intended to recycle the system in an eco-friendly manner. System elements which cannot be recycled shall be transferred in an eco-friendly manner to a waste treatment plant or - in the worst case - to a final storage.

Exemplary Product Content

The deactivation shall take into account the following technical conditions which must be described in the Subject Disposal:

• Condition of the system
• Packaging
• Preservation
• Archiving of data
• Scheduled maintenance
• Reactivation

The description of waste management shall take into account the following issues:

• Condition of the system
• Company neutralization (demilitarization)
• Dismantling (including deletion of sensitive data)
• Rendering safe
• Disposal possibilities (scrappage, sale)
• Recycling
• Special waste
• Final storage
