Detailed Description

This class models 'simple job shops', its classifier if "J". The precedence relation for the operations is a simple chain. The chain corresponds to a list of machines where the job has to pass (in this order) during its execution, the so called "workplan". Access the modifier to set properties.

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]

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 > SJobShop::getMachinesFor (  const SShopJob &    job, int    op )  const [virtual]

Get a list of machine positions, where the specified operation may be executed, i.e. the workplan entry for operation 'op'. Parameters: job  job op  operation Returns: list of machine positions Implements SGeneralShop. Reimplemented in SFlowShop, and SSingle.

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

Get access to the modifier Implements SGeneralShop. Reimplemented in SFlowShop, and SSingle.

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

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

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

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

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

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]

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]

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]

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
