In this paper, for effective multi-echelon supply chains under stochastic and fuzzy environments, an inventory management framework and deterministic/stochastic-neuro-fuzzy cost models within the context of this framework are structured. Then, a numerical application in a three-echelon tree-structure chain is presented to show the applicability and performance of proposed framework. It can be s...

This paper presents a two-echelon non-repairable spare parts inventory system that consists of one warehouse and m identical retailers and implements the reorder point, order quantity (R, Q) inventory policy. We formulate the policy decision problem in order to minimize the total annual inventory investment subject to average annual ordering frequency and expected number of backorder constraint...

In this research, the optimal pricing decisions for two complementary products in a two-echelon supply chain under two scenarios are studied. The proposed supply chain in each echelon includes one retailer and two manufacturers and the same complementary products are produced. In the first scenario, we assume the unit manufacturing costs of the complementary products in each echelon are the sam...

Driven by the new laws and regulations concerning emission of greenhouse gases, it is becoming more popular for enterprises to adopt cleaner energy. This research proposes a novel two-echelon vehicle routing problem consisting mixed vehicles considering battery swapping stations, which includes one depot, multiple satellites with unilateral time windows, customers given demands. The fossil fuel...

We seek to optimize the production planning of a three-echelon remanufacturing system under uncertain input data. consider multi-stage stochastic integer programming approach and use scenario trees represent information structure. introduce new dynamic formulation that relies on partial nested decomposition tree. then propose extension recently published dual algorithm based this decomposition....

The notion of Echelon spaces was introduced by Köthe [2] as a means of constructing sequence spaces by taking the intersection of multiples of I1 (see below for definitions). The definition was extended by Dieudonné and Gomes [l] to include lp for \^p< °o. It is the purpose of this note to consider the case, p = co. AH of the terminology defined below is due to Köthe. A sequence of complex numb...
