Hi Harichai, If I understand your model correctly then I think you will want to sum the variables who timeslots occur on the same date. - Riley

Hi Harichai, I meant for the timeslot list to include dates as well, not be separate list from dates. If you look closely at what I wrote then I think you will realize this. - Riley

No problem Jingwei. Although my suggestion is to avoid this approach when building your models - if they are large models.  If the time to build the models is large then, if you want to describe wh...

If I was to formulate this problem I think I would index most variables by a timeslot for every day, i.e. gp_manpower_status = model.addVars(timeslot_list, manpower_list, order_list, ...) timeslot_...

Hi Daniel, It's certainly not an obvious question! We don't have the ability to embed simulation models in the optimization process, but as of Gurobi 10 we do have the ability to incorporate a diff...

I'm wondering if this is possible for this chart. Referring to the first chart there is a B14 in cell (Supachai, five) and (Phonlawat, six).  So you have to shift everything in Supachai row from B1...

If I understand correctly, timelist does not feature in your model - it is only used in construction of the table? In which case this problem is to do with displaying of data, and nothing to do wit...

Hi Harichai, But I just want the command to work with division work start in the same column. If you look at it in terms of time, you have to start doing it together. I understand this, but I don...

Hi Harichai, If B19 appears in both "three" and "four", doesn't this mean that  gp_order_status[three, B19] == 1gp_order_status[four, B19] == 1 or have I incorrectly assumed what these variables ar...

Hi DR, gurobipy.quicksum takes exactly one argument, and that argument should be an iterable such as a list, tuple or generator expression.  You can use a generator expression like so: gp.quicksum(...
