ATLAST™ - Predictive Life-cycle Logistics Impact Forecasting
Clockworks Solutions' Advanced Total Life Cycle Assessment Software Tool (ATLAST™) simulation model was specifically designed to support life-cycle simulation-based logistics impact forecasting for new and aging weapons system fleets.
Unique ATLAST Functionality
- Captures the current, on-the-ground state of a weapons system fleet
- Operates them according to operations profiles for the base they are located
- Forces failure and life limited events according to location and age of components
- Administers the capacity-constrained maintenance and logistics support processes to return unserviceable assets back to operation
ATLAST is a SPAR-based model application that forecasts the impacts of what-if scenarios on maintenance and logistics policies, or proposed policies, with regard to mean time to removal, availability, part condemnations, assembly removals for repair and spares consumption. ATLAST was developed to deal with the multi-site, multi-indenture realities of complex military operations and support infrastructures. Database inputs are used to establish and initialize models for simulation and analysis.
With ATLAST, a projected return on investment over time in terms of readiness and costs can be determined based on decisions to change sustainment policies, such as increasing or reducing:
- Part life-limits
- Life-limit screens
- Reliability refresh
- Repair effectiveness
- Equipment age
- Repair capacities at select repair locations
- Repair turnaround (improved tooling or methods)
- Planned operations
- Spares
- Order lead times
- Shipment time
- Fleet size
- Part substitutability
Comprehensive Performance Metric Forecasting
With ATLAST, detailed impact analysis can be evaluated through outputs that include:

- Asset or fleet availability/readiness
- Number of unplanned LRU removals
- Number of LRU inductions for overhaul at the depot
- Counts of depot actions for each type of assembly
- Number of time triggered events for each type of assembly
- Failure counts per type of assembly
- Number of spares used
- Awaiting Parts – what, how long, how often (AWP)
- Awaiting Maintenance – what, how long, how often (AWM)
- Life cycle expenditures (cost)
Answering Mission-Critical Questions
ATLAST was designed to answer key questions such as "what will happen, when will it happen, and what will it cost us?" Specifically, ATLAST analysis addresses such crucial questions as:

- Will the fleet, or assets at some operating location, achieve required operations and readiness?
- Will the planned buy plan be suitable to maintain expected and target availability?
- What will the parts requirements be?
- How do improvements in repair capacity impact repair turnaround time and time on wing?
- Where will the repair and supply bottlenecks be?
- What can I expect to have in the repair pipeline due to removals for cause and life-limited parts?
- What volume of part condemnations will occur and where?
- Will a repair location be able to keep up with the demands anticipated?
- What percent of time is repair held up due to awaiting parts or awaiting maintenance conditions?
- What performance gain (fleet availability, time on wing, repair turn around time) is obtained through selection of an alternate part type, with respect to part and vendor attributes such as order lead-time, ship time, purchase cost, and reliability?
- If fatigue-testing results in modified life limits on certain parts, how will that change effect maintenance and supply volume?
- I have a limited budget, how should/could I spend it across supply and maintenance functions to maximize fleet availability?
The Power of Initialization

Prior to simulating future asset performance, it is critical to initialize the state of the current system. ATLAST provides a dedicated database for upload of asset configuration, operations, and corrective maintenance history. These categories are used to correctly position each asset and its components on a variety of expected life curves. Thus, the expected performance of each asset is treated uniquely within the simulation, as it enters planned operations and support. By way of example, an old part, or even a part with previous repairs, will impact support requirements more than a new part with no repair history. ATLAST tracks and manages such relationships for hundreds of thousands of items throughout the simulation periods.
