A simulation-based finite capacity MRP procedure not depending on lead time estimation

International Journal of Operational Research (IJOR), Vol. 11, No. 3, 2011

Abstract: The two main limits of material requirements planning (MRP) systems are: (1) MRP does not take into account production capacity constraints and (2) lead time values are pre-defined input of the procedure. The approaches developed so far solve the first limitation by considering capacity constraints out of the procedure. Target of this paper is to define a new MRP method that overcomes these limitations. In particular, the proposed procedure, through a simulation model, allows to obtain a plan, which complies with resources capacity and which does not need to receive estimated lead time values as input. The proposed method has been applied to a case presenting all the elements of complexity of the MRP phase. A comparison of the performance of the new procedure with the traditional one shows that the new one takes effectively into account capacity constraints and provides feasible plans.
