Simplifying Multiproject Scheduling Problem Based on Design Structure Matrix and Its Solution by an Improved aiNet Algorithm

Pseudocode 1

Pseudocodes of identification process of resource conflicts.

PROCEDURE OF THE MODEL SIMPLIFICATION AND IDENTIFICATION OF RESOURCE

CONFLICT

(1) confirm activities between projects or in one project

(2) if activities in one project

   if(DSM ([ij, jk],:) = K) ∈𝐹𝐽 then

    ij, jk belong to EJ

     if (q_ijr+ q_ikr) > Q_r  then

     resource conflict exists between 𝑖𝑗 and 𝑖𝑘

    else

     there are no resource conflicts between ij and ik

(3) ifactivities between projects

   if (q_ijr+ q_ikr) > Q_r  then

    resource conflict exists between ij and ik

   else

    there are no resource conflicts between ij and ik

(4) update EJ, BJ and FJ

  if there are no activities needed scheduling

    process finished, otherwise go on.

(5) end
