question

I'm thinking you're going to need to keep track of the number of times a staff member completes an activity by using your own counter. Your "counter" can be a label on the staff, or an array of global variables, or simply a global table. I'd probably opt for using a global table to keep track of the counters ,because it sounds like you're going to want a two dimensional array of counters. For instance, you could use each row of a global table to keep track of all the counters for a specific staff member, and each column of the table would represent the counters associated with a specific activity.

With some creative use of our Custom Data Collectors and User-Defined graphs you may be able to come up with a way to display the information you're looking for within a dashboard, but personally I wouldn't bother with all the extra work and would just use the global table itself as the way to display the information. Global tables can be dynamically updated during the simulation run and the cell values in the table display will update and be visible on the fly as well.

There is a standard pick list option available in various triggers throughout the software called "Increment Table Cell" which you could use to increment a particular cell of a table. To increment the table cell associated with a specific activity of a specific staff member, you will need come up with a scheme for determining the correct table row number for a given staff member and the correct table column number based on the activity, so you probably will want to write the script yourself using the "Custom Code" option for the trigger field.

Here's an expression you could use in an Activity Finished Trigger field to increment a counter if you like. The expression assumes that staff members already have a label named "RowNum" defined on them that has been set with the row number in the global table named "ProcedureCounters" that you want associated with the particular staff member. I'm also assuming that the expression is written in the Activity Finished Trigger field of the an activity that is associated with column 3 of the global table:

inc(gettablecell(ProcedureCounters, getlabel(resource,"RowNum"), 3), 1);

As for adding a restriction so that a particular staff member cannot be called to perform an activity if their procedure count for that activity exceeds a certain number, I can think of a couple different approaches depending on the scope of the problem. You could either use a Decision Point activity to direct the logic to one or more predefined activities that have been set up with different staffing requirements based on the counter value looked up out of the ProcedureCounters table, or use the "Configurable Selection Policy" option in the "Member Selection Policy" field of the staff group objects affected by the special max procedures restriction.

Let me know if there's anything you don't understand, and I'll do my best to clarify.
