A processing node is selected from an actual workflow definition composed of the corresponding processing nodes to an actual service flow according to the purpose of use of a client. A virtual workflow definition composed of the virtual node corresponding to the selected processing node is created by a server and displayed on a screen of the client. A link is set for indicating correspondence between the virtual node of the virtual workflow and the processing node of the actual workflow. When an inquiry about the progressing state of the virtual workflow is given from a client, the server searches the processing node being current executed from the actual workflow. If the processing node does not have any link, the server tracks back the processing nodes on the actual workflow for searching the processing node having the link and an access right given from the client and then reply the progressing state of the processing node as the progress information of the virtual workflow to the client.

A multi-media method and system performs psychological assessment of an individual for suitability for particular jobs, whereby the individual is shown and provided with discrete visual and auditory stimuli on a multi-media computer screen, so that the individual's responses can be monitored in conjunction with physiological responses received by biofeedback sensors. The computer tallies the test subject's recorded responses. Virtual work environments are optionally displayed, to enable the tested individual to simulate a real work environment. Unlike other job evaluation systems, the system evaluates a job candidate's ability to maintain task focus under pressure. It directly measures performance under pressure, rather than only inferring potential performance based upon selective input from a job candidate.

To select a relative velocity profile to be used in scanning an actual work piece with an ion implant beam of an ion implantation tool, the implantation of a virtual work piece is simulated. A dose distribution is calculated across the virtual work piece based on an implant beam profile and a relative velocity profile. A new relative velocity profile is then determined based on the calculated dose distribution and the relative velocity profile used in calculating the dose distribution. A new dose distribution is then calculated using the new relative velocity profile. A new relative velocity profile is determined and a corresponding new dose distribution is calculated iteratively until the new dose distribution meets one or more predetermined criteria. The new relative velocity profile is stored as the selected relative velocity profile when the new dose distribution meets the one or more predetermined criteria.
