the study determined optimum inventory levels for various bakery resources using the bread supply chain network in onitsha city. structured questionnaires were administered among bakery factories. the optimum design achieved through the optimization model was compared with the existing systems. analysis of 90 bakeries with a combined capacity of 3960 revealed that total money n 564,408,477.28 i...

Many companies face challenges in reducing their supply chain costs while increasing sustainability and customer service levels. A comprehensive framework for a sustainable closed-loop (CLSC) network is practical solution to these challenges. Hence, the first time, this study considers an integrated multi-objective mixed-integer linear programming (MOMILP) model design CLSC networks with cross-...

this paper explains a model for analyzing and measuring the propagation of order amplifications (i.e. bullwhip effect) for a single-product supply network topology considering exogenous uncertainty and linear and time-invariant inventory management policies for network entities. the stream of orders placed by each entity of the network is characterized assuming customer demand is ergodic. in fa...

today, due to the direct and reverse logistics plays an important role in reducing the costs in supply chain. in this paper, in order to provide a closed-loop supply chain network including supply centers, production, distribution, collection, recycling and disposal of a used linear mixed integer programming. this paper to consider multi-period and multi-product in multi-level supply chain and ...
