ams.core.service.MinDur

class ams.core.service.MinDur(u: Callable, u2: Callable, name: str = None, tex_name: str = None, unit: str = None, info: str = None, vtype: Type = None, no_parse: bool = False, sparse: bool = False)

Build the coefficient matrix for minimum online/offline constraints used in UC.

Note: inherits from NumOpDual for parameter plumbing only. The parent's fun/rfun/args machinery is unused; this class fully overrides .v to build the duration matrix from u (a horizon-bearing Var) and u2 (a RParam carrying the minimum duration in time units).

Parameters:

uCallable

Input, should be a Var with horizon.

u2Callable

Input2, should be a RParam.

namestr, optional

Instance name.

tex_namestr, optional

TeX name.

unitstr, optional

Unit.

infostr, optional

Description.

vtypeType, optional

Variable type.

no_parse: bool, optional

True to skip parsing the service.

sparse: bool, optional

True to return output as scipy csr_matrix.
