Opis:: In this paper, the approach consists in selecting the best secondary breakage process of oversize blocks with explosives for the limestone quarries. To solve this problem, we propose the centroid weight method for weighting the selection criteria, and the PROMETHEE model as a multicriteria decision making method. A case study is carried out in the limestone quarry of the cement factory of Hadjar-Soud, Algeria.

Opis:: The awareness of making decisions in an imprecise environment has resulted in considering the inventory system under a fuzzy approach. The effects of uncertain demand have been finding increased application in many inventory systems. Uncertainty creates complicated situations for the manufacturer in making decisions. Markets have become more competitive as a result of technological advancements. The effect of inflation on the overall cost of the inventory system is useful in providing a tool for the analysis of inventory decisions. This study intended to estimate the effect of different fuzzy numbers on a manufacturer's annual joint expected total cost. The comparative study of this proposed model has been considered for two different fuzzy numbers with the defuzzification technique as the centroid method. The optimization technique has been used to minimize the producer’s joint expected total cost under the condition mentioned earlier, and the model is validated numerically.
