Integrated Project Scheduling and Staff Assignment with Controllable Processing Times

Procedure 3

Function buildSolution().

Procedure  buildSolution(ne_𝑗, TO, EO)

 foreach  set 𝑆_𝑖  do

   foreach  task according to TO  do

     set the starting time of the task 𝑗 (denoted 𝑥_𝑗) according to the release time of

     this task and the completion times of the predecessors of the task, looking for

     the minimum possible starting time

     repeat

     assign employees, who are able to perform the task, to the task following

      the EO until the ne_𝑗 is reached

      if  the assignment is unfeasible  then

      𝑥_𝑗:= 𝑥_𝑗+1

      end

     until  the assignment is feasible;

   end

 end

 check the feasibility of the solution
