Detailed Description

Base class for all shop environments, the classifier if "G". A general shop stores the structure of a shop job: the duration of operations of which it consists and the precedence relation between them. Access the modifier to set properties. The durations are stored as 'partial processing times', i.e. as percentages of the processing time of the job (which is stored in SJob) NOTE: This class is not implemented yet and serves merely as base class for all other shop-classes. It may become a starting point for more sophisticated job shop models (for example with sets of admissible machines for each operation)

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

virtual leda_list<int> SGeneralShop::getAvailOperations (  const SShopJob &    job )  const [pure virtual]

Get the list of all operations of a job that may currently be executed (depending on the precedence relation) Parameters: job  job Returns: list of operations Implemented in SJobShop, SOpenShop, and 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

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

Get a list of machine positions, where the specified operation may be executed. Parameters: job  job op  operation Returns: list of machine positions Implemented in SFlowShop, SJobShop, SOpenShop, and SSingle.

virtual SEnvironmentMod& SGeneralShop::getModifier (    )  [pure virtual]

Get access to the modifier Implements SEnvironment. Implemented in SFlowShop, SJobShop, SOpenShop, and SSingle.

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

Return the operation to be executed next Implemented in SJobShop, SOpenShop, and SSingle.

virtual int SEnvironment::getNumOfMachines (    )  [pure virtual, inherited]

Get the number of machines in this environment Returns: number of machines Implemented in SBroadcast, SIdentical, SJobShop, SOpenShop, SSingle, SUniform, and SUnrelated.

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

Return the number of operations of which the job consists Implemented in SJobShop, SOpenShop, and SSingle.

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

Get the partial processing time of a specific operation of a job (depending on the current embedding ... this is ignored up to now because the processing times in our shop models are independent from the machine where the job is running) Parameters: job  job op  operation mach  reference to SMachines Returns: percentage of the operation 'op' of the whole relative processing time of 'job'; i.e. a value between 0 and 1 Implemented in SJobShop, SOpenShop, and SSingle.

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

Return the remaining execution time of the current phase of a job if it runs without preemption assuming that everything stays as it is (embedding etc) Parameters: job  reference to job machines  reference to the machines Returns: total execution time Implemented in SJobShop, SOpenShop, SSingle, and SUnrelated.

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
