The "General costs - monthly" and "General costs - yearly" outputs show the monthly and yearly average cost per item, based on your cost inputs.
The general costs include all ports, transportation and personnel costs.
The categories are divided into the following main categories, with the subcategories:
- Total

- Transport consumption
- Fuel consumption
- Transport cost
- Consumables cost
- Day rate cost
- Fuel cost

General costs - Monthly
Example for monthly - if the annual cost of base staff is set to 500000, and the annual cost of facilities is 200000, the calculations are:
Facilities cost: 200000/12=166666.666667 per month
Base staff cost: 5000000/12=416666.666667 per month
The output file will display the monthly cost per item, with a total row for each item; this total is the accumulated cost for the whole year.
General costs - Yearly
Example for yearly - if your case runs for has 10 years, and the annual cost of base staff is set to 500000, and the annual cost of facilities is 200000, the calculations are:
Facilities cost: 200000*10=2000000 for the whole simulation
Base staff cost: 5000000*10=5000000 for the whole simulation
The output file will display the yearly cost per item, with a total row for each item; this total is the accumulated cost for the simulation (all years).
