In the last decade many companies have recognized that important cost savings and improved service levels can be achieved by effectively integrating production plans, inventory control and transportation policies throughout their supply chains. In this paper, an integrated multi-commodity production and distribution planning model is presented. A proposed Mixed Integer Programming (MIP) model is developed...
Many technological solutions for rural areas, even after successful demonstrations, have not been able to reach the intended beneficiaries at the scale and speed required to address their underlying problem. The Million Soul Urja Lamp Program (MSP) is an effort to take solar lamps to rural India to address their primary energy needs, through localization and skill development. This paper outlines...
We describe an ongoing research effort on the development of a decision support system (DSS), called TISCSoft, that is designed to facilitate critical decisions related to transportation infrastructure planning in the public sector and supply chain planning in the private sector. This DSS implements mathematical models developed as part of a recently completed research effort titled Freight Movement...
Construction logistics comprises planning, coordination and supervision of material flow to, within and from construction sites. Good construction logistics on construction sites saves time and construction costs. To plan construction logistics, numerous interferences between configuration of construction site and construction work have to be considered. In particular in outfitting processes, their...
The paper presents an approach towards a new concept for maintenance supply chain (MSC) optimisation exemplified on spare parts management and its logistic chain. Maintenance organisations operate in complex supply chains confronted with strong interdependencies (e.g. integration of service and logistics providers). Concurrently they need to perform efficiently to guarantee the required availability...
Supply Chain Management (SCM) is now an important strategy for companies to gain competitiveness. However, the cost is still the key factor to face. This paper proposes a novel approach to create an optimal logistic plan in SCM with failures such that the required total capacity for logistics is minimum while the reliability retains the highest. Since the globalized economics changes very fast, the...
Supply Chain Operations Reference (SCOR) model is developed and maintained by the Supply Chain Council (SCC). The model is a reference model which can be used to map, benchmark and improve the supply chain operations. SCOR model provides companies with a basic process modeling tool, an extensive benchmark database and defines a set of supply chain metrics. Mobarakeh Steel Company (located in Isfahan,...
With the recognition of the necessity for effectively preventing and minimizing enterprise logistics risks, this paper seeks to propose an early warning indicators system (EWIS) for enterprise logistics risks based on the balanced scorecard (BSC) in order to maximize the possibilities of desired performance. This paper is the first attempt to apply the BSC framework on the early warning indicators...
The rapid development of Chinese exhibition industry requires correspondingly logistics service. Outsourcing is an effective solution to the many problems existing in the process of exhibition logistics development. Based on analysis of the characteristics of exhibition logistics, the paper analyzed the necessity and the obstacles of exhibition logistics outsourcing, constructed an effective exhibition...
The objective of the study is to minimize the whole cost of logistic system in view of the long-term planning level. Based on traditional EOQ model, a non-instantaneous replenishment inventory decision model is presented in consideration of transportation cost and the permitted working duration of the vehicles per unit time. The optimal ordering quantity is obtained by the ideas of getting the minimum...
The distribution problem in supply chain is studied in this article. To minimize the logistics cost in upstream and downstream enterprises in supply chain, Bi-level Programming Method is innovatively used in this article to establish the optimization model of the supply chain network distribution. Solving methods for this model are discussed and then an efficient arithmetic combined with layered iterative...
The importance of supply chain management (SCM) is well recognized, but there is lots of confusion about it in academia and business community. This paper discusses the SCM modes in the perspective of logistics, organization, operation management and strategy management respectively, and summaries the common attributes of SCM modes. The results can be useful to better grasp the implications and significance...
Timber is a valuable raw material which is very much in demand for the substantial as well as for the energetic use. The use of timber or wood raw material in Germany has increased during the last years. Due to a changing market with more competitors in the same sector and higher logistics costs for raw material supply the involved parties in the timber logistics supply chain are facing new challenges...
As the supply chain becomes more complex, the ability to gain a consistent view of business operations, especially, to track in real time a certain product or pallet becomes more important. Establishing visibility of product flow across the supply chain is one means to achieve this goal. This in turn can adversely affect the responsiveness of supply chain and decision making processes. The RFID visibility...
This paper builds up the planning model of logistics nodes for strategic supply chain by applying the theory of complex network. A practical mathematical modeling framework has been further suggested, which is expected to focus on some significant aspects of network design problems, including the relocation of existing nodes through capacity transfers to new locations, integration of inventory, transportation...
In the last decades we have seen a steady growth of international trade and international transport. Logistics chains are constantly changing to facilitate these increasingly global movements. In qualitative terms, long-term trends in logistics services indicate a growing degree of product customisation and an increased responsiveness in order delivery. These developments impact on the development...
In a price-sensitivity supply chain (PSSC), there often has nonlinear relationships between products' price and its quantity. In order to obtain the optimal production and distribution structure of a PSSC, the paper builds an integer nonlinear planning(INLP) model of the network planning for a multi-factories, multi-DCs and multi-retailers supply chain which has price sensitivity characteristics on...
As the number of Internet purchases increases, logistics becomes more significant in e-commerce. This paper develops an integrated model of third-party agile logistics (TPAL), which is divided into three hierarchies, from top to bottom namely the principle tier, planning tier, and tactic tier. According to the relationship of top-down guidance and bottom-up support, this study puts forward and detailed...
The term logistics has been studied with the increasing recognition about its importance to enterprises, organizations as well as the national economy. The logistics center is an important node in supply chain. Two key factors have to be considered for the scheme of the logistics center: one is how to assign the orders to suppliers, and the other is choice of transportation strategy. This paper has...
