Relationship of the existing constraints in the logistics system: (antinomy principle)

(1) restrictive relationship between logistics services and logistics costs.

(2) constitute a constraint relation between logistics services subsystem function.

(3) constitute the relationship between the cost of all aspects of the logistics cost. Restrictive relationship between the transport and storage fees.

(4) and the cost of each subsystem with the relationship.

Logistics system mode:

1, input: a role of a system by providing the resources, energy, equipment, labor and other means, collectively referred to as the external environment, the logistics system input.

2, Processing (conversion): production, supply, sales, service and other activities carried out by the logistics transformation process, from input to output logistics business activities referred to as the processing or transformation of the logistics system.

3, Output: position and place the transfer; a variety of labor, energy, information; good service

4, Limit or constrain the external environment impose certain constraints on the logistics system known as the constraints and interference of the external environment on the logistics system.

5, Feedback: Logistics celebrate input into the process of output, due to limitations of the system, a variety of factors, not originally planned to achieve, need to return the output to the input, make adjustments, even if the original plan to achieve, we should also returns the information to make evaluations of work This is called feedback. Activities include: analysis of all the logistics activities; a variety of statistical reporting data; typical survey; domestic and international market information and trends.

Logistics systematic target (5S)

(1) service

(2) speed

(3) efficient use of area and space

(4) the scale of the appropriate

(5) Inventory Control

Logistics system design factors: commodity, quantity, flow direction, services, time and cost of the PQ, R, S, TC six elements.

System analysis: from the best of the system, based on selected goals and guidelines, to analyze the functions and interrelationships of the various subsystems constitute the system and the interaction with the environment of the system. Run scientific analysis methods and tools, for the purpose of the system. Function. Environment. Full investigation of the costs and benefits, fear, comparison, analysis and data processing, and the establishment of a number of alternatives and the necessary models, system simulation test, test, analysis, and the calculated results with the previously developed plan and evaluation, seek to make the overall system efficiency and limited resources with the best solution, the final decision of the decision-makers to provide a scientific basis and information.

The role of systems analysis: in a very important position in the overall system building process, which play a connecting role. There are three phases: system planning, system design, system implementation.

The characteristics of the systems analysis: the overall goal, specific problem. The use of quantitative methods. With the value judgment.

Transportation methods and features:

Rail and water transport: it is large, low shipping costs, suitable for long distance, the main transport of large quantities of goods are applicable to heavy thick grew up, economic and transport mileage for more than 200-300 km. Mouth capacity is not inflexible, to supporting, loading and unloading times. Road transport: suitable for close, low-volume, multi-species, multi-batch transport, transportation, short, light, door to door, the drawback is the lack of long-distance transport and the main transport of large quantities of the advantages of exhaust gas nuisance, air transport: fast, less than high transport costs, but it is small,

1, railway transportation: land-based long-distance way from the conditions of transport impact can be overloaded high-speed operation and transportation units;

2, Road transport: the freedom of space-time, is not bound by line stops, door to door direct transportation, packaging can be simplified, cargo damage, lost and misdirected unlikely;

3, Waterway transport: high-volume and long-distance transport cheaper to transport a very large and overweight;

4, Air transport: fast, short time loss of goods, suitable for the transportation of fresh goods, high transport costs;

5, Pipeline transportation: maintenance costs of cheap transport large quantities of supplies are not labor-low transport costs, small footprint, fewer security incidents nuisance less, transport locations conveying object limitations

Transport rationalization of the way:

1, the rational allocation of the transportation network: the difference between storage type warehouse and distribution warehouse open, rational allocation of the logistics base.

2, Select the best mode of transport.

3, improve operational efficiency.

4, promote the common transport.

5, color a variety of modern methods of transportation. Joint multi-modal transportation, consistent pallet transport, container transport, the bulk of transport, intelligent transport, door to door transportation.

Warehouse functions:

1, storage and custody of

2, Regulate the function of supply and demand.

3, regulate cargo transport capacity.

4, the distribution and circulation of processing capacity.

(1) macro-logistics. Macro Logistics is the logistics activities of social reproduction in general, awareness and research from the overall point of view of the social reproduction of logistics activities. Macro-logistics can also be understood from the spatial scales in a lot of room areas of logistics activities, often with a macro, in a very small space areas of logistics activities, often with microscopic. The main features of the macro-logistics research we look at and the overall situation. The main contents of the macro-logistics, logistics and overall structure, logistics and social relations in society, the relationship between logistics and economic development, social logistics system and establishment of international logistics systems and operation.

(2) micro-logistics. Consumer, producer enterprises engaged in the actual, specific logistics activities are micro-logistics. Logistics activities, being a local, a part of the specific logistics activities are micro-logistics. Are micro logistics specific logistics activities in a small geographical space.

(3) Social Logistics. Social logistics beyond a one to a social community for the purpose of logistics-oriented areas.

(4) Enterprise logistics. From a business perspective on research related to the logistics activities is the typical field of the specific micro-logistics activities.

(5) international logistics. International Logistics is a modern logistics system has developed rapidly, large field of logistics, international logistics is to accompany and support international economic exchanges, trading activities and other international exchange activities of logistics.

(6) Regional Logistics. International logistics, a country within the scope of logistics, the logistics of a city, an economic region of logistics in the same law, under the rules and regulations are subject to the same cultural and social factors are in basically the same technology level and equipment level.

(7) the general logistics. General logistics, logistics activities have in common and general logistics activities is an important feature of involving the whole society, enterprises, the establishment of the logistics system, logistics activities must have general applicability.

(8) special logistics. Specialization, specialized areas, special industry, on the basis of following the general logistics law, with special constraints, special applications, special management, the special object of labor, and logistics of special machinery and equipment characteristics, all belong to the special logistics range
