I was able to reproduce the examples, even though i got very confused, but i  undestood some things, but i'm really lost of how to implement my own project/rule.

My paper is about service, I don't really know how to define it, but i'll try to explain.

A given company receive several requests of maintence, repair, etc, all the time, and it have a number of people to solve that, these technicians. It's something like the nurse roaster but waaaay to simpler.

An issue can pop at any minute, it have a starting time and an estimated time to be acomplished.

The technician have work for a fixed amount of time, but he have the start time and the end time of work, that I want to use to assign the issue.

I've created the class Technician

Technician

----------------------------

import java.util.Date;

import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("Technician")
public class Technician extends AbstractPersistable {

    private int engId;
    private int workTime;
    private Date startWorkTime;
    private Date endWorkTime;
   
    private Technician technician;

    public Technician(int engId, int workTime, Date startWorkTime,
            Date endWorkTime) {
        super();
        this.engId = engId;
        this.workTime = workTime;
        this.startWorkTime = startWorkTime;
        this.endWorkTime = endWorkTime;
    }

    public int getEngId() {
        return engId;
    }

    public void setEngId(int engId) {
        this.engId = engId;
    }

    public Date getStartWorkTime() {
        return startWorkTime;
    }

    public int getWorkTime() {
        return workTime;
    }

    public void setWorkTime(int workTime) {
        this.workTime = workTime;
    }

    public void setStartWorkTime(Date startWorkTime) {
        this.startWorkTime = startWorkTime;
    }

    public Date getEndWorkTime() {
        return endWorkTime;
    }

    public void setEndWorkTime(Date endWorkTime) {
        this.endWorkTime = endWorkTime;
    }

    public Technician getTechnician() {
        return technician;
    }

    public void setTechnician(Technician technician) {
        this.technician = technician;
    }

}

------------------------------------

Issue class

------------------------------------

import java.util.Date;

import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("CloudComputer")
public class Issue extends AbstractPersistable {

    private Date startTime;
    private Date estimatedTime;

    public Issue(Date startTime, Date estimatedTime) {
        super();
        this.startTime = startTime;
        this.estimatedTime = estimatedTime;
    }

    public Date getStartTime() {
        return startTime;
    }

    public void setStartTime(Date startTime) {
        this.startTime = startTime;
    }

    public Date getEstimatedTime() {
        return estimatedTime;
    }

    public void setEstimatedTime(Date estimatedTime) {
        this.estimatedTime = estimatedTime;
    }

}
--------------------------------

and here i got lost. I'm trying to schedule the technician to these issues based on the estimated time and in the time left of technician.

I accept any kind of help or comment, I need it for next monday, i'll be tunned everytime on this trying to make it happen.

Thanks for your time
