Crews, vessels and plant windows serve repair queues and outage schedules. Pick the decision, such as how many crews or which work package sets the restart date, and test it before you commit.
Decision: which crew and vessel plan keeps faults open the shortest time? The model sends each fault to a crew that needs a part and a safe window. You read the time a fault stays open with its confidence interval for each plan.
What flows
Turbine fault, panel fault, planned service visit, spare part request
What is scarce
Technician teams, crew transfer vessels, cranes, weather windows
Where it waits
Fault backlog by priority, vessel boarding queue, parts waiting for delivery
Questions you can test
How many technician teams keep the open fault backlog from growing in winter?
Does a second vessel cut waiting time more than a larger crew on the first one?
What happens to downtime when planned services and urgent faults compete for the same team?
How much does a stricter weather limit lengthen the wait for a repair?
Which fault type drives most of the queue at the port?
Grid restoration and storage dispatch
Decision: how many crews and which switching sequence restore customers fastest after a storm? The model sends outage tickets to crews, with storage dispatch rules that return power to some customers early. You read the customer wait for power and the slowest step with confidence intervals.
Line crews, control room operators, bucket trucks, battery cycles
Where it waits
Tickets waiting for fault location, switching queue, repairs waiting for a crew
Questions you can test
How many crews clear a storm surge within the target restoration time?
Does an earlier call for mutual-aid crews pay off, or does the extra crew wait idle?
Which step holds tickets longest: location, switching or repair?
How often does the battery run out of charge before the repair ends?
What changes if two control room operators are on shift instead of one?
Hydrogen and green fuel supply chain
Decision: which link limits deliveries, and what does an outage cost downstream? The model sends batches through electrolyzer, storage and trailer loading bay, using your batch sizes, trip times and outage pattern. You read deliveries with their confidence interval.
What flows
Production batch, tube trailer load, pipeline delivery order
Batches waiting for storage space, trailers waiting for a bay, orders waiting for stock
Questions you can test
How many trailers keep delivery orders from backing up during a long outage?
Does a second loading bay help, or does storage space limit the chain first?
How long can an electrolyzer stay down before the buyer goes short?
What batch size balances loading time against storage fill?
Carbon capture and nuclear outage
Decision: which work package or shortage pushes the restart date? The model schedules work packages that compete for specialist crews, cranes and inspection slots, with your durations and crew counts. You read the restart date with its confidence interval before the shutdown begins.
What flows
Work package, inspection request, rework order
What is scarce
Welding crews, riggers, cranes, inspection slots
Where it waits
Packages waiting for a crew, lifts waiting for a crane, packages waiting for inspection
Questions you can test
Which work package most often sets the restart date?
Does a second crane or a third welding crew shorten the outage more?
How many inspection slots are enough before they stop being the limit?
What does a failed inspection cost in days once rework queues are counted?
How wide is the spread in finish time across repeated runs of the same plan?
Green data center and cooling operations
Decision: where does one more technician or chiller pay off? The model sends rack requests, fault tickets and cooling failures to the same limits. You read ticket wait and requests blocked with confidence intervals.
Technicians, spare power slots, spare cooling slots, chillers
Where it waits
Install requests waiting for capacity, tickets waiting for a technician
Questions you can test
How many technicians keep install requests and urgent tickets both under control?
Does a standby chiller shorten install waits more than another technician?
How long do installs pause after a cooling fault?
What priority order for tickets keeps live racks safest without starving installs?
Recycling and critical materials flow
Decision: does more equipment or a better schedule lift throughput? The model sends mixed loads through each step and shows the wait at each. You read the limiting step and throughput with confidence intervals.
What flows
Inbound truck, sorted stream, bale or batch of recovered material
What is scarce
Sorters, shredders, truck docks, storage bays
Where it waits
Trucks waiting for a dock, material waiting for a sorter, bulky items waiting for the shredder
Questions you can test
Which stage limits the tonnage the plant can process in a shift?
Would a second shredder help, or does sorting stall the line first?
How often do full bays block the docks?
What do longer dock hours do to truck waiting time?
Does separating streams earlier reduce the load on the shredder?
Water utility and ocean field operations
Decision: what fleet size, roster and priority rule fit the weather uncertainty? The model sends leak repairs and sampling trips to crews and vessels that the weather may hold. You read the repair wait and the planned work delayed with confidence intervals.
