Detailed Description

Flow shop environment, a specialized job shop; its classifier is "F". This class models a job shop where the workplan is simple (1, ... , machines), i.e. every job must be executed on all machines in a fixed order. Access the modifier to set properties.

Constructor

Member Function Documentation

virtual void STypeInfo::assureInstanceOf (  const leda_string &    classifier )  const [pure virtual, inherited]

The same as isInstanceOf(), only that the program is stopped with an error in case of failure Parameters: classifier  e.g. "P", "Q", "R", etc

leda_list< int > SJobShop::getAvailOperations (  const SShopJob &    job )  const [virtual, inherited]

Get the list of all operations of a job that may currently be executed. Here: all non-finished operations are returned. Parameters: job  job Returns: list of operations Implements SGeneralShop. Reimplemented in SSingle.

virtual leda_string STypeInfo::getClassifier (    )  [pure virtual, inherited]

Get the classifier of the object, using the classification scheme. E.g. "P" for Identical Processors Returns: classifier string

leda_list< int > SFlowShop::getMachinesFor (  const SShopJob &    job, int    op )  const [virtual]

Get a list of machine positions, where the specified operation may be executed. In flow shops the machine position corresponds to the operation. Reimplemented from SJobShop. Reimplemented in SSingle.

virtual SEnvironmentMod& SFlowShop::getModifier (    )  [inline, virtual]

Get access to the modifier Reimplemented from SJobShop. Reimplemented in SSingle.

int SJobShop::getNextOperation (  const SShopJob &    job )  const [virtual, inherited]

Return the operation to be executed next Implements SGeneralShop. Reimplemented in SSingle.

virtual int SJobShop::getNumOfMachines (    )  const [inline, virtual, inherited]

Return the number of machines Implements SEnvironment. Reimplemented in SSingle.

int SJobShop::getNumOperations (  const SShopJob &    job )  const [virtual, inherited]

Return the number of operations of which the job consists Implements SGeneralShop. Reimplemented in SSingle.

double SJobShop::getPartialProcTime (  const SShopJob &    job, int    op, const SMachines &    mach )  const [virtual, inherited]

Get the partial processing time of a specific operation of a job. Parameters: job  job op  operation mach  is ignored, because machine-operation-combination is fixed in open shops Implements SGeneralShop. Reimplemented in SSingle.

double SJobShop::getRemProcTimeOn (  SJob &    job, const SMachines &    machines )  const [virtual, inherited]

Get the remaining processing time of the currently processed operation of a job Parameters: job  job that is currently running (processing a certain operation) machines  reference to SMachines Returns: total processing time of current operation Implements SEnvironment. Reimplemented in SSingle.

const leda_array< int > & SJobShop::getWorkPlan (  const SJob &    job )  const [virtual, inherited]

Get the whole workplan for a job. An array of machine positions will be returned: the i-th entry corresponds to the machine, where the i-th operations must be executed. Parameters: job  job Returns: workplan

virtual bool STypeInfo::isInstanceOf (  const leda_string &    classifier )  const [pure virtual, inherited]

Checks whether the object is an instance of the specified or a specialized class Parameters: classifier  e.g. "P", "Q", "R", etc Returns: true if the object can be casted to the specified class
