TimeStruct is a Julia package that supports the efficient development of optimization models with multi-horizon time modelling and possible uncertainty. The package is designed to be used in combination with the JuMP package for optimization modeling in Julia.
] add TimeStruct
The following shows a simple example of usage. For further details we refer to the documentation.
using JuMP
using TimeStruct
periods = SimpleTimes(10, 1) # 10 periods of length 1
income = FixedProfile(5.0) # Fixed income profile
model = Model()
@variable(model, x[periods] >= 0)
@constraint(model, sum(x[t] for t in periods) <= 4)
@objective(model, Min, sum(income[t] * x[t] for t in periods))If you find TimeStruct useful in your work, we kindly request that you cite the following:
