Firms with omni-channel multi-echelon distribution networks (OMDC) integrate all of their sale channels and echelons to achieve an effective matching multi-type orders a shared inventory. However, the high operational cost caused by insufficient use inventory resources unreasonable order allocation restricts sustainable development firms. To this end, joint decisions optimization (IO) (OA) are ...

We review multi-echelon inventory models for repairable items. Such models have been widely applied to the management of critical spare parts for military equipment for around three decades, but the application to manufacturing and service industries seems to be much less documented. We feel that the appropriate use of models in the management of spare parts for heavily utilized equipment in in...

Nowadays, Companies have to deal with an uncertain demand which is more difficult to handle when it has a non-stationary pattern. Simultaneous decrease of customer service and increase of stock costs are the most significant effects of such demand uncertainty. To deal with this issue, inventory optimization models must be adapted to cover a multi-echelon network structure and to consider altern...

This paper is concerned with the numerical evaluation of multi-echelon production systems. Each stage requires a fixed predetermined leadtime; furthermore, we assume a stochastic, stauonary eLd.tlmc demand process. In a previous paper, we have developed an analytical framework for determining optimal control pohclcs for such systems under an average COSt criterion The current paper Is based on ...

Cointegrated VARMA models can be parameterized by using the echelon form, which is characterized by the Kronecker indices. Three diierent methods for estimating the Kronecker indices of cointegrated echelon form VARMA models are discussed and compared. They have the common feature of estimating the individual equations of the system separately and using order selection criteria. The small sampl...

Supply chain management (SCM) is an emerging field that has commanded attention and support from the industrial community. Supply chain (SC) is defined as the chain linking each entity of the manufacturing and supply process from raw materials through to the end user. In order to increase supply chain effectiveness, minimize total cost, and reduce the bullwhip effect, integration and coordinati...

Abstract We present a multi-ob’jective two-echelon vehicle routing problem with synchronization and ‘grey zone’ customers arising in the context of urban freight deliveries. Inner-city center deliveries are performed by small vehicles due to access restrictions, while outside this area carried out conventional for economic reasons. Goods transferred from first second echelon synchronized meetin...

Increasing environmental concerns and legal regulations have led to the development of sustainable technologies systems in logistics, as many fields. The adoption multi-echelon distribution networks use environmentally friendly vehicles freight become major concepts for reducing negative impact urban transportation activities. In this line, present paper proposes a two-echelon electric vehicle ...

Purpose This study focuses on a specific method of meat production that involves carcass purchase and by packing facilities with novel two-stage model simultaneously considers location-routing inventory-production operating decisions. The considered problem aims to reduce variable fixed transportation costs, inventory holding cost the opening cold storage facilities. Design/methodology/approach...
