Abstract
The materials requirements planning (MRP) approach, applied in production planning and management has some weaknesses. One of those is the discreteness of time so called time periods in this approach which makes it impossible to order the requirements at irregular time moments or periods. In this paper, a new form of MRP, named as continuous materials requirements planning (CMRP) approach, is introduced. Moreover, the priorities and advantages of this approach over the discrete MRP (DMRP) one are further discussed and the conditions and manner of CMPR application in different types of problems are analyzed. The CMRP system, introduced in this paper does not have any safety stock (SS) and its order type (OT) is lot for lot (L4L). For applying this system, several algorithms and lemmas along with their proofs are also described. Also two numerical examples with one real case study are presented.
