A REVIEW OF MANUFACTURING RESOURCES PLANNING MODELS UNDER DIFFERENT UNCERTAINTIES: STATE-OF-THE-ART AND FUTURE DIRECTIONS

The main purposes of this paper are to enhance the understanding of manufacturing resources planning models under uncertain conditions by documenting the current state of affairs, and to stimulate a fruitful future research direction by identifying gaps between the relevant issues and the literature available in reputable journals. This paper is a comprehensive and up-to-date review of the existing literature on manufacturing resource planning models under uncertainty. The authors have found that the combined effects/ impacts of the uncertainty factors on the system parameters have yet to be thoroughly studied. So far no research has been conducted into developing mathematical model(s) to study the uncertainty issues holistically in multi-period, multiple product, and multi-stage environments for manufacturing resources planning in association with commonality. OPSOMMING Die primere doel van hierdie artikel is om die insig in vervaardigingshulpbronbeplanning onder onsekerheid te bevorder. Die huidige stand van sake word ondersoek en gapings word uitgewys aan die hand van literatuur beskikbaar in gesaghebbende joernale. Die outeurs bevind in die studie dat die sisteemparameters en die invloed van onsekerheid daarop nog nie voldoende bestudeer is nie. Geen navorsing is nog onderneem om wiskundige modelle te ontwikkel om op holistiese wyse die impak van onsekerheid in multi-periode, veelvoudige produk en multi-stadium omgewing te bestudeer nie.
