one of the most fundamental components of healthcare system on each country is blood supply chain management. this chain is comprised of two significant components including collecting donor’ bloods and supplying blood’s products. the main purpose of this paper is to concentrate on supplying blood products and present a novel constrained bi-objective mathematical model for a two-echelon blood s...

The effective management of supply chains depends upon the ability of decision makers to control inventory while maintaining customer service at low cost. This paper examines an analytical model for the two-echelon one warehouse and multiple retailers system using (R, Q) inventory policies. A simulation model was developed to analyze the performance of the analytical model under conditions that...

In this paper, an inventory model for deterioration items in a two-echelon supply chain including one retailer and one manufacturer is proposed by considering the stock and price dependent demand and capacity constraint for holding inventories. First, the model is presented as a leader-follower game in which the manufacturer announces wholesale prices. Second, the retailer decides for the order...

The paper "Sustainable integrated and pricing decisions for two-echelon supplier–retailer supply chain of growing items" (authors: Mukunda Choudhury Gour Chandra Mahata), v.55(5), pp.3171-3195, September-October 2021, RAIRO Operations Research, after a very careful investigation process, which proved the existence plagiarism, was retracted by editorial board this journal.

The bullwhip effect refers to the phenomenon of demand distortion in a supply chain. By eliminating or controlling this effect, it is possible to increase product profitability. The main focus of this work is to apply a control technique, based on the divergence of system, to reduce the bullwhip effect in a single-product one echelon supply chain, in which an Order-Up-To (OUT) order policy is a...

A supply-chain is a series of connected stock management structures. Therefore, the structure of a supply-chain consists of many cascading inventory management problems. It is known that the optimal inventory control parameter values suggested by the literature are also valid for a supply-chain. The motivation for this study is to investigate the effect of the literature suggested optimal value...

In this paper, a multi-objective multi-period multi-product supply chain network design problem is introduced. This problem is modeled using a multi-objective mixed integer mathematical programming. The objectives are maximizing the total profit of logistics, maximizing service level, and minimizing inconsistency of operations. Several sets of constraints are considered to handle the real situa...

Model predictive control (MPC) is presented as a robust, flexible decision framework for dynamically managing inventories and satisfying customer demand in demand networks. In this paper, a formulation and the benefits of an MPC-based, control-oriented tactical inventory management system meaningful to the semiconductor industry are presented via two significant examples. The translation of ava...

We examine the impact of RFID-point of sale data sharing on ordering decisions in a two-echelon supply chain. Theoretical studies have shown that accessibility to point of sale data can impact supply chain dynamics. We study this phenomenon from a behavior examination in the content of a simple, serial supply chain that is subject to stochastic demand and information time-lags using a controlle...
