Detailed Description

A Gantt chart contains all information about what time a job was allocated and deallocated, on which machine a job was processed and how often a job was running.

Member Function Documentation

SGanttChart::DUMMYIO (  SGanttChart    )

int SGanttChart::getExecInfo (  int    jobIdx, leda_array< double > &    start, leda_array< double > &    end, leda_array< int > &    machine, leda_array< int > &    operation )  const

Get the information about when and where a job has been executed. For each interval 0..i of an execution of the job, start-time, end-time, the executing machine and (with shop jobs) the executed operation will be copied to the corresponding start[i], end[i], machine[i] and operation[i], if job is not a shop job, operation[i] will return -1; All information of the arrays will be deleted before filling them. Parameters: jobIdx  index of job start  will return start time of execution interval i end  will return end time of execution interval i machine  will return the machine where the job was executed operation  will return the executed operation of the job Returns: the number of execution intervals of the job ( = size of the arrays )

int SGanttChart::getJob (  int    mach, double    time, int &    operation )  const

Get the index of the job, that was running on machine 'mach' while time step 'time'. If the job is a shop job, 'operation' will return the operation processed at that time, -1 if not a shop job; NOTE: If in time step 'time' a old job was deallocated and a new job was allocated, then it returns the old job Parameters: mach  position of machine time  the time step operation  will be filled with the operation of the shop job, -1 if job is not a shop job Returns: The index of the job that was running on machine 'mach' at time step 'time', -1 if no job was running

int SGanttChart::getMachine (  int    jobIdx, double    time, int    operation = -1 )  const

Get the machine, that executed job 'jobIdx' at the specified time step. With shop jobs you also have to specify the operation NOTE: if at timestep time the job was deallocated from machine 'old' and allocated on machine 'new', the 'old' one will be returned Parameters: jobIdx  index of the job time  the time step operation  the operation of the job ( only has to be specified when the job was executed in a shop environment ) Returns: The position of the machine that executed 'operation` of job 'jobIdx' at time step 'time', -1 if such a job wasn't executed at that time.

const leda_list<double>& SGanttChart::getTimeSteps (    )  const [inline]

Get a list of all time steps at which jobs have been deallocated. this list can be used to create the time axis of the Gantt Chart and to iterate the time for getJob(); NOTE: timeStep 0 is not in this list Returns: list of all time steps (except time step 0)

void SGanttChart::jobAllocated (  int    jobIdx, int    machine, double    time, int    operation = -1 )

Inform the chart that a job has been allocated Parameters: jobIdx  index of allocated job machine  position of machine the job is running on time  the time when the job has been allocated operation  which operation of a job is been processed ( only valid for jobs in a shop environment )

void SGanttChart::jobDeallocated (  int    jobIdx, int    machine, double    time )

Inform the chart that a job has been deallocated Parameters: jobIdx  index of deallocated job machine  position of machine the job was running on time  the time when the job has been deallocated

SGanttChart::NOCOPY (  SGanttChart    )

void SGanttChart::reset (    )

Reset datastructures. Do this at the beginning of a new schedule or when the number of jobs or machines has changed
