1 Introduction The modern logistics, as the traditional logistics technique and sustainable development combination model, is thought of an important profit headspring except for helping business of enterprise lower the supplies consume and increase the rate production. The good future of logistics is based on Green logistics. Logistics is the integrated management of all the activities required to move products through the supply chain. For a typical product this supply chain extends from a raw material source through the production and distribution system to the point of consumption and the associated reverse logistics [1]. The logistical activities comprise freight transport, storage, inventory management, materials handling and all the related information processing. The main objective of logistics is to co-ordinate these activities in a way that meets customer requirements at minimum cost. In the past this cost has been defined in purely monetary terms. As concern for the environment rises, companies must take more account of the external costs of logistics associated mainly with climate change, air pollution, noise, vibration and accidents. This research project is examining ways of reducing these externalities and achieving a more sustainable balance between economic, environmental and social objectives. In supply chain of four flows, namely material-flow, business-flow, funds-flow and information-flow, the material-flow is being promoted to unprecedented high degree, which is the foundation of logistics. The real time and accuracy of material-flow is the necessary of the logistics success. With the development of logistics science, environment has been evolved into its important and key research objective. The environment in whole process of logistics has been being studied by various scholars. Such environment is an emerging emphasis concept in logistics science. Now days, researches on logistics are more loosely scattered and have not been developed into a systematic and scientific environmental theory system [2]. This paper departs from traditional operations research procedures in that it tries to avoid detailed descriptions of both problems and their solutions. In fact a goal of our analyses will always be to determine what is the least amount of information that is needed to make a rational decision, and to use the simplest approach possible to identify good solutions. These features of our approach can help overcome the decision-makers' natural distrust of "black-boxes", and be quite helpful in instances where time is of the essence. This is not to say that the more traditional detailed approaches to problem solving should not be used; when time and information availability allow it, numerical detailed methods have proven to be quite useful. Yet, even in these instances detailed solutions sometimes can be improved if they are preceded by exploratory analyses as described in this paper.
2 Sustainable Development and Green logistics 2.1 Sustainable Development Sustainable development, according to the World Commission on Environment and Development, is
533
“development that meets the needs of the present without compromising the ability of future generations to meet their own needs." ["Our Common Future", 1987] sustainable development means: finding ways to increase prosperity and improve the quality of life while reducing overall pollution and waste; meeting our own needs and aspirations without doing damage to the prospects of future generations; Reducing the environmental burden we put on our neighbors and helping to preserve common resources. In other words, the concept of sustainable development requires a change of mindset to bring about full integration of the needs for economic and social development with that to conserve the environment. It also requires the Government and all sectors of the community to work hand in hand in order to achieve a sustainable future. [3] 2.2 Green logistics The proposing of sustainable theory requests enterprise’s logistics activity change tradition model which consumptions the massive energy, and produce the noise and the waste gas pollution. So the concept of Green logistics was bought out. The development of modern logistics must consider the environment question firstly, which needs make the improvement from the environment angle, namely, needs to form a Green logistics. This kind of the Green logistics is profit for prompting global environment, and which is based on sustainable development. Green logistics is concerned with producing and distributing goods in a sustainable way, taking account of environmental and social factors. Thus the objectives are not only concerned with the economic impact of logistics policies on the organization carrying them out, but also with the wider effects on society, such as the effects of pollution on the environment. Green logistics activities include measuring the environmental impact of different distribution strategies, reducing the energy usage in logistics activities, reducing waste and managing its treatment. In recent years there has been increasing concern about the environmental effects on the planet of human activity and current logistic practices may not be sustainable in the long term. Many organizations and businesses are starting to measure their carbon footprints so that the environmental impact of their activities can be monitored. Governments are considering targets for reduced emissions and other environmental measures. There is therefore increasing interest in Green logistics from companies and governments [4]. 2.3 Reverse Logistics Along with environmental protection laws and regulations' releasing and enhancement of the people environmental protection consciousness, the reverse logistics has displayed the great social and economic value and caused the domestic and foreign theorists and the practical realm enormous attention. The reduction of waste means that Reverse Logistics should be included within Green Logistics. There are various definitions of Reverse Logistics to be found in the literature. For example, Fleischmann et al. (1997) say that reverse logistics is “a process which encompasses the logistics activities all the way from used products no longer required by the user to products again usable in a market”. Dowlatshahi(2000) explains Reverse Logistics as “a process in which a manufacture systematically accepts previously shipped products or parts from the point for consumption for possible recycling, remanufacturing or disposal”. Later, the European Working Group on Reverse Logistics, REVLOG, Decker et al.(2004), give this definition: “The process of planning, implementing and controlling backward flows of raw materials, in process inventory, packaging and finished goods, from a manufacturing, distribution or use point, to a point of recovery or point of proper disposal” [5].
3 Establishment Model of Green logistics System 3.1 Analyses of Logistics System Logistics, the subject of this paper, is defined here to be the science that studies how to convey items 534
from production to consumption in cost-effective and environmental ways; some subjects of interest to logistics managers such as reliability and maintenance are not addressed. Besides transportation, a logistics system usually includes other activities such as inventory control, handling, and sorting, which must be carefully coordinated if cost-effectiveness is to be achieved, which include environment also. Yet, both in theory and practice these activities are often examined separately. The operations research field includes sub-fields with specialized journals in inventory control, transportation, warehousing, etc... Over the years, these sub-fields have evolved into disciplines that have developed their own specialized conventions and jargon, as a result making it increasingly difficult for researchers to communicate across disciplinary boundaries. Something similar happens in practice when firms become compartmentalized; if responsibilities for different logistical activities are allocated to different managers, decisions in Green logistics are difficult (if not impossible) to make. This paper represents an attempt to examine Logistics System in an integrated way. By necessity, we will not represent any of the activities as precisely as would be done in each one of the sub-fields, but we will try to model them accurately enough to capture their essence. Our goal is to describe, and show how to find, rational structures for Logistics System, including their operation and organization. 3.2 The Model of Green Logistics System Integrated with traffic and transportation, storage and delivery, logistics industry realizes low cost and high benefit in enterprises and society. Therefore, logistics industry, together with internet industry, is looked on as the important content of "New economy", and it is widely known as the third profit source and gold mine of the market. The Green logistics has been underlined by many nation and researches accompanied the increasing attention on environment protection from the public. The paper presents the model of Green logistics in brief under the establishing of the Green logistics which is based on the environment protection and an implement strategy has been put forward. As follow: (1) Green Supply Chain The conflict among population, resource and environment requires the manufacturing to develop environmental management strategies. The green supply chain management (GSCM) is an effective way to solve the problem. The concept model of green supply chain is constructed, and strategic objects of green supply chain management are analyzed based on sustainable development theory. The basic principles of green supply chain management are discussed, which include the intergrowth theory, the cycle theory, the switchover theory and the open system theory. [6] (2) Green Production Logistics The purpose of green production logistics is to ensure that each machine and workstation is being fed with the right product in the right quantity and quality at the right point in time. The issue is not the transportation itself, but to streamline and control the flow through the value adding processes and eliminates non-value adding ones. Production logistics can be applied in plants. Manufacturing in an existing plant is a constantly changing process. Machines are exchanged and new ones added, which gives the opportunity to improve the production logistics system accordingly production logistics provides the means to achieve customer response and capital efficiency. 3 Green Transportation Logistics The purpose of green transportation logistics is to reduce consumption of energy in transportation, reduce discharge discard material and reduce transport tool occupancy road pass through effective project and control materials circulation system. The green transportation logistics proposes strategies such as strengthening management of routing; enhance loading, market operating and inter-management based on the duration rising of cost. 4 green packaging The increasing of waste had impacted the sustainable development and packaging waste was an important part of the solid waste. Green packaging discussed the whole process of packaging life cycle, and put forward some measures which can make packaging waste minimizing, including laws and rules, economic instrument and recycle system. (5) Green Distribution processing Distribution processing refers to goods from production to use the process, as required on packaging,

segmentation, measurement, sorting, assembly, to pay the price stickers, labels affixed to pay, commodity inspection, and other simple operations collectively. Distribution processing is characters of production, but also the logistics departments can accomplish a great deal of profit in environmental protection area. [7] Green Distribution processing includes two major aspects: First, changing the consumer processing to the focus professional processing, the firms dependent on the scale of operations to improve the efficiency of resource use, reducing environmental pollution. Second, the logistics firm collects the processing of scrap materials, to reduce pollution caused by the waste of the spread consumers processing. (6) Green Distribution Logistics Green Distribution Logistics is great significance under buyer's market conditions. It is not just simply door-to-door, and warehousing, classification, packaging, handling and transport rationalization of its customers at the lowest cost; it more important provides a good service to win customers trust. (7) Waste material logistics Required by the sustainable development of resource, environment, society and economy, waste material logistics should be paid much attention. The value of waste material logistics is increasingly appearing. Waste material logistics has reverse and uncertain and complex features. Benefit-balance principle, prior-control principle and system principle should be abode by in the management of waste material logistics [8].
4 In Case Aug 2005, Shanghai Petrochemical Company (SPC) successfully accomplished the implementation of the green logistics system. This is the biggest change in logistics management systems in petrochemical industry in China and the systems facilitated SPC stepping toward its vision of “Advanced management, first-class of service, high efficiency third party logistics (3PL) company which provides comprehensive logistics service”. Benefited from the new logistics management system, the operation efficiency of SPC was highly improved.
5 Conclusion Along with the thing flowing industry development, increased the new content in the green logistics, which had the new ten major tendencies. Changes the union by the opposition. In the traditional commercial logistics, the enterprise mostly takes as the center, pursues the self- benefit, and therefore often makes the aspect which the enterprise opposes. However in under the pursue bigger competitive power actuation, many enterprises starts in each commercial circulation function the conformity, through the union plan and the work, forms highly the conformity supply chain channel relations, causes the channel overall result and the effect large promotion. [9] Changes the relative value by the absolute value. The traditional finance appraisal will look only some absolute values, the new appraisal method emphatically in the relative value creation, that is will provide adds the value service in the channel, and in the value which the customer will increase the enterprise may account for how many proportions.
