I. INTRODUCTION
Since 1990s, the enterprise competition gradually
entered into the era of supply chain competition [1].
Enterprise gradually becomes from facing the market
competition to facing the Supply chain competition. For
example, Hebei province is one of the provinces which
have lots of coal industries, But, when the coal industry
gain the competitive advantages through the supply chain,
in the same time, it also consumes lots of resources and
makes a huge damage to the ecological environment[2]. So,
building and implementing green supply chain
management (GSCM), becomes the key link to gain the
competitive advantages for the coal chemical enterprise[3].
The existing problems of the green supply chain
management in coal enterprise:
Firstly, the coal chemical enterprise is still staying in
the traditional purchasing stage when purchasing, they
usually ignore the environmental friendly indicator,
energy consumption, etc. So, it is difficult to control the
purchased product’ green degree; in the same time under
the simultaneous purchase mode, purchasing department
ignore the change of production process, production
schedule and product demand, thus cause long purchasing
cycle and low efficiency problems [4].
Secondly, in the production course, the green degree
is lower. Designing the product, we always consider cost,
quality, product function and so on, and ignore the
negative influence, like environmental pollution, the
consumption of energy, etc[5]; The subject of the selfconducting logistics for production logistics mode, leads
to the high logistics cost, low efficiency, low green level.
Thirdly, in the marketing process, the green level is
lower. In the marketing, the low information sharing rate
among supply chain enterprise and the sufficient
information communication and sharing make part goods
do not match customer requirements any longer, thus lead
to the higher product costs and lower green levels[6].

In this paper, combined with the specific
characteristics, we firstly construct the evaluation index
system according to the principle of index system of
evaluation. The evaluation index system includes six oneclass indexes and twenty-six secondary indexes.

Secondly, we can calculate the indexes weight by
constructing the judgment matrixes.
Thirdly, we calculate the GSC performance index
membership grade[7].
Fourthly, we can make the single factor and multiactor evaluation by establishing the fuzzy relation matrix.
In the end, we can get the results of evaluation of the coal
chemical enterprises.
III. RESULTS
According to the above the evaluation process, we
can get the comprehensive performance evaluation of
GSC of the chemical enterprise is 75.9, which is over 70
score. This means that GSCM of the enterprise in the
Hebei province is a medium level. But it is not optimistic
becauce one-class indexes score of “sustainable
development”、“Environmental performance” and “Cost”
are 66.7,58.9,69.2, which is lower than 70 score. Through
the thorough analysis, we find that Secondary indexes
such as “Waste recycling”, “Emissions”, “Raw material
and resource utilization”, "Scientific research investment
rate” and so on lead to the three factors lower than the the
industry standards. As a result, we must start to analysis
environmental performance, cost and sustainable
development in order to construct GSCM of the coal
chemical enterprises successfully, and then we can take
measures to improve[8].
The Design of Green Supply Chain in coal chemical
enterprises:
A. Construction of the green procurement program
(1) Choice of green materials. High quality coals can
not only improves product quality, reduces environment
pollution, reduces raw material usage, but also can save
energy and reduce the "three wastes" emissions,
effectively prevent corrosion of process equipment[9] .
(2) Establish and develop strategic partnership with
suppliers. Good relations of cooperation will not only help
suppliers to provide qualified products according to the
requirements of coal chemical industry, but also take the
constraints of the green supply chain into account in the
design and before taking green products into mass
production, it can make product cleaner and better
quality[10]. Coal chemical enterprises conduct technical
training for suppliers, and make to win situation with the
company to establish strategic cooperative relations by
providing financial resources.
(3) Build a unified procurement platform. Coal
chemical enterprises can use the methods of "intensive" to
purchase, it means making the decentralized procurement
projects focus on harmonization of procurement by the
department of purchasing corporation[11]. Coal chemical
enterprises can obtain economies of scale, at the same
time they can increase the level of green procurement
logistics by a reasonable classification of the
procurement.
B. Construction of the scheme of green production.
(1) The implementation of green design and cleaner
production. Coal chemical enterprises should introduce
new technology and new materials, etc. and basing on
"reduce, reuse, recycle." principle of circular economy.
Coal chemical enterprises should strengthen the
implementation of green design and cleaner production.
(2) Improve the degree of green logistics. Coal
chemical enterprises should take a different approach for
different categories which are based on the item’s
features, performance and strengthen the construction of
green storage. The enterprises can further enhance the
level of storage while ensuring the production through the
design of safety stock. At the same time, they should
strengthen the care and maintenance during storage and
make good explosion-proof, moisture, corrosion,
waterproofing, leak-proof and so on[12].
C. Construction of the green consumption
(1) Give correct guidance of green consumption.
Firstly, the Chemical enterprise should makes the sales
staff know the green sales idea and green product
environmental protection, Then through the varieties of
publicity approaches and communication methods, we can
change the customers’ demand of life or production
environment quality into the dominant actions which is
useful for environment promotion[13]. Through network
implementing on-line sales, enterprise can help the
purchaser to understand the green value quickly and
accurately, and then give the correct guidance of green
consumption.
(2) Make the green package. Enterprises should take
the economic principles of "reduction", "reuse ", "
recycling " into accordance, negotiate with the upstream
and downstream firms to make sure the products packing,
achieve the goal of moderate packaging, flexible
packaging and recycle packaging, In the premise of
product quality, we try to use " nullity packing", reduced
packaging or circulating packaging as far as possible, and
choose the green packaging materials[14].
(3) Carry out joint distribution to improve sales
logistics green degrees. Chemical companies need to
establish a quantitative mode for sales logistics
management, through the methods of "large delivery cut
the fees" and "containerization cargo cut the fees"
to achieve logistics rationalization. Meanwhile, through
the joint with other enterprises, develop a common
distribution business to improve the distribution logistics’
green level.
D. Construction of waste recycling scheme
(1) Strengthen the construction of waste recycling
system. Chemical enterprise should unite other
enterprises, which are in or out of the supply chain
network to establish a waste recycling system[15]. Then
waste materials of the end could be back into the supply
chain, thus can reduce the environment pollution and
improve resources recycle rates effectively.
(2) Strengthen the recycling rates of waste solid. At
the end of the chemical enterprise production, the solid
waste is mainly fly ash. The enterprise can establish a
comprehensive utilization of coal ash production
engineering, using fly ash to produce Portland cement by
confecting method, to realize the goal of low cost, low
pollution, but high effect, high production.
(3) Strengthen the recycle of industrial waste air. The
mainly of industrial waste air in coal chemical industry
enterprises are NXO, aromatics, SO2, coke oven gas, etc.
The enterprise can introduce advanced technology,
transfer production process, purchase environmental
protection facilities, to reduce the gas production
effectively. We can use coke oven gas to produce
methanol or to conduct electricity, then make new profit
growth points[16].
In short, for promote the sustainable development of
coal industry, establishing and enforcing GSCM has
practical value. And for promote social economy’s
development rapidly and healthily, building and
implementing GSCM can also play a positive role.
