Summary: Make a principle according to green, built include quality (Q) , cost (C) , environment is affected (E) the cutting fluid much target of 3 big decision-making targets is decision-making system, the cutting fluid that put forward to face green to make accordingly chooses model and relevant tie condition integratedly, pass applied example test and verify the feasibility of this model. 1 foreword environment, resource, population is the 3 big main problems that current mankind society faces. The environmental aggravation that human activity causes is opposite of human society live to constitute serious menace with development. In recent years, international Organization for Standardization issued standard of quality management system in succession (ISO9000 series) , level of environmental management system (ISO14001) and professional safety and level of sanitation management system (OHSAS18001) , quality management, environment governs and professional safety and sanitation management bring into company general management, improve level of management in the round for the enterprise, strengthened comprehensive strength to provide administrative measure and tool. During the environmental problem that poses in manufacturing industry is acerb with each passing day, one kind gets used to the advanced production pattern that can develop the strategy continuously -- green is made begin to cut a figure. Green is made is the contemporary production mode of influence of environment of a kind of integrated consideration and resource efficiency, its target is to make product from the design, make, pack, carry, use discard as useless the to the environment influence in the whole product lifecycle of processing (negative effect) for 0 or the smallest, make resource disappear extinct the likelihood is little, make business economic benefits and social benefit get harmony optimizing. In cutting treatment process, cutting fluid is one of main pollution causes that cause environmental pollution. Use the problem such as the green cutting fluid, environment pollution that reduces cutting fluid to already became green to produce one of research heat of the domain. The United States is close hold the problem undertook the proper dosage of fluid of the cutting in installing technical university to be machined to cutting consider, make cutting fluid dosage least below the circumstance that tries to ask in contented treatment, with period fall the charge that concerns with cutting fluid to lowest. American Thyssen production company is studying with all one's strength " the smallest lubricant " processing technique, make the current of cutting fluid or gas mist carry cutting tool action at machining area, the discharge of cutting fluid by CNC programme controll, the effect is idealer. Sun Jianguo of Shandong industry university was based on product lifecycle to undertake study to the green sex of cutting fluid. Production carries out a proof, fluid of logical choice cutting can develop the property of cutting fluid adequately, managing finished cost, reduce the cutting fluid pollution to the environment, accordingly, one of important ways that undertake to cutting fluid the choice is pollution of fluid of the cutting in reducing treatment process optimizing. The article is considering the foundation of the decision-making target such as cutting fluid quality, cost and environmental influence integratedly to go up, built the cutting fluid that faces green to make to choose a model integratedly to reach its to restrain a condition, combined manufacturing example to undertake analytic test and verify to the applied method of this model and feasibility. The 2 cutting fluid that face green to make choose a model integratedly build the author from 20 centuries at the beginning of 80 time since direct to be being made with green the resource in relevant production system and energy problem undertook study for a long time, the T(time that put forward to be based on green to make) , Q(quality) , C(cost) , E(environment is affected) , R(resource is used up) the decision-making cause system that waits for variable of 5 big decision-making targets and corresponding decision-making frame model. Green makes medium any decision-making problem as variable as 5 afore-mentioned decision-making targets medium certain (or all) the element is concerned. Afore-mentioned models are in the light of production system character only, did not build specific cutting fluid to choose a model integratedly. The article makes the foundation of cause system and decision-making model go up in green, combinative cutting fluid chooses medium specific issue, decision-making cause system and decision-making target decompose the cutting fluid that put forward to face green to make frame variable group, built the cutting liquid that has maneuverability to choose a model integratedly on this foundation. Decision-making problem cause system faces the cutting fluid that faces green to make the cutting juice that green makes selects an issue integratedly is a many target, qualitative the complex and decision-making issue that combines with mensurable photograph. Want to build decision-making model, need to decide decision-making variable above all, namely the objective that decision-making activity pursues. When choosing cutting fluid by traditional pattern, the target variable that people goes after basically is quality (Q) and cost (C) . Among them, the lubricant, refrigeration that quality basically points to cutting fluid and clean function to reach its to use cycle and utilization rate; Cost includes economic cost (cost of material, establishment and facility cost, labor cost, energy cost) , user cost (use cost, maintain cost) reach other is miscellaneous a cost. When the manufacturing industry of industrial developed country is choosing cutting fluid, divide outside needing to satisfy cutting to machine craft to ask, pay attention to the element such as processing of the harm with consideration cutting healthy to person fluid, waste liquid and integrated cost more. This one viewpoint is being accepted by place of industry of domestic cutting treatment gradually. Facing the cutting juice that green makes to select decision-making cause system is affect the environment (E) tries to consider as a main factor, decision-making target variable is the cutting fluid that faces green to make namely quality (Q) , cost (C) and environment (E) 3 elements, lowest of highest, cost, environment affects variable to these 3 targets pursuit eventuate quality the smallest. Q, C, E3 put in close tie between decision-making target, they make the cutting juice that faces green to make jointly decision-making cause system. In this system of decision-making target vector if the graph is shown 1 times,disclose content. Decision-making cause system decomposes the cutting fluid that the graph faces green to make the environmental influence of content cutting fluid basically includes the following 3 respects: To the influence of zoology environment: The effect that the likelihood such as the waste gas that this index basically points to to in producing a course, arise, waste liquid, trash causes to zoology environment. Cutting fluid basically reflects the useless oil to will been used in cutting treatment, waste liquid to wait to be discharged directly or do not burn via effective processing to environmental harm the pollution that causes to water natural resources or air. In addition, the cutting liquid that uses in cutting treatment can be put more or less stay in cut bits, contain remaining cutting juice because of this pair after cutting bits and end of cutting fluid life, deal with undeserved cause an effect possibly also to the environment, if cut bits,a large number of accumulation can contaminate soil, the poisonous and harmful composition of fluid of the cutting when undertaking to cutting bits second birth is used also can pollute an environment. To professional health, safety and healthful influence: This index basically points to the likelihood in producing a course to be damaged to what professional laborer health causes. Cutting fluid behaves the additive in be cutting fluid above all to the harm of human body (as usual uses the phenol that makes antiseptic kind material) have bigger noxiousness; Next, activator of the mineral oil in cutting fluid, surface the excitant meeting of the defatted action that wait and anticorrosive antiseptic makes human body skin dry, defatted, cause craze, red, fester to wait even; In addition, the bases mineral oil of fluid of oil radical cutting is mixed the respirator official to the person also has the basic material in fluid of water radical cutting to endanger effect certainly. Unreliability: This index basically points to the unreliability that arises because of all sorts of reasons in producing a course. A variety of additive are contained in cutting fluid, cause equipment possibly in use process to corrode, rusty and cause fire to wait for insecure element. The variable of decision-making problem describes the cutting fluid that faces green to make cutting fluid is decision-making the essence of the problem is use plan optimize a problem, single out from inside a certain number of possible plan namely best or opposite relatively the plan of actor. When undertaking optimizing to the use plan of cutting fluid, all involved variable all can use vector of dimension of a N to describe, namely X=[x1, x2, ... , in Xn]T type, n is potential treatment program number, xi(i=1, 2, ... , n) represents I treatment program, and have Xi={0, do not use I plan 1, use I plan model choice and tie condition are based on afore-mentioned analysises, build the cutting fluid that faces green to make to choose a model integratedly to be as follows: Target function is: Q(X)(is used at describing quality decision-making target) , C(X)(is used at describing cost decision-making target) , E(X)(is used at describing an environment to affect decision-making target) . Optimize described as MaxQ(X) , minC(X) , minE(X) → Optimum[Q(X) , c(X) , e(X)] builds the decision-making model that the cutting fluid that faces green to make chooses integratedly to be as follows: Choose decision-making problem X=[x1 to some cutting fluid, x2, ... , xn]T, beg a X*=[x1* , x2* , ... , xn*]T satisfies 0(u=1 of ≤ of tie condition Gu(X) , 2, ... , k)hv(X)=0(v=1, 2, ... , P<N) makes Optimum[Q(X) , c(X) , e(X)]=[Q(X*) , c(X*) , e(X*)]X ∈ Rn among them, x* is sort of best cutting fluid. Models of afore-mentioned cutting fluid choice are one is in give ambient conditions (namely systematic tie is attrib border, like limited natural resources control and contented treatment craft ask) plan with the much goal that establishs below the target model. This model has two ties requirement: Gu(X) restrains a condition for the inequality of the model; Hv(X) restrains a condition for the equality of the model. Discuss as follows respectively: Equality restrains conditional Hv(X) to X=[x1, x2, ... , xn]T, either X is equal to 0(not to adopt this plan namely) or 1(uses this plan) namely, and the optimal program X*=[x1* that chooses integratedly, x2* , ... , xn*]T is to satisfying equality to restrain conditional X1*+x2*+ ... + the optimal value of function of the target below the circumstance of Xp*=1, namely Optimum[Q(X) , c(X) , e(X)]=[Q(X*) , c(X*) , e(X*)] . Inequality restrains conditional Gu(X) to the target function Q(X) in the model, c(X) , e(X) , on the foundation that machines craft requirement in contented cutting, all be differred the relevant tie of the quality of plan, cost and environmental target. To X=[x1, x2, ... , xn]T(x1, x2, ... , xn is equal to 0 or 1) , beg a X*=[x1* , x2* , ... , xn*] , contented inequality restrains Bi(u=1 of conditional Gu(X) ≤ , 2, ... , k)(among them Bi is quality target tie, cost target tie, environmental target tie and raw material to restrain) respectively, get Optimum[Q(X) , c(X) , e(X)]=[Q(X*) , c(X*) , e(X*)] . 3 application example analyses factory of some machine tool to machine Central Plains to use 32# engine oil to regard cutting as oil in gear hobbing, have certain harm sex to worker health and treatment facilities, and useless oil is more unmanageable. Run systematic level to carry out quality (ISO9000 series) , level of environmental management system (ISO14001) and professional safety and level of sanitation management system (OHSAS18001) , this factory hopes to use a kind of homebred and new-style green to synthesize cutting fluid SG-3 or entrance to synthesize cutting fluid (the 32# engine oil that 3% Synthetic Oil) will come to replace a tradition. The cutting liquid that uses what the article puts forward to face green to make chooses decision-making model integratedly, can make a system to this problem decision-making. Plan describes the plan of this problem to describe equation to be X=[x1, x2, x3] among them: Xi(i=1, 2, 3)={0, do not use I plan 1, use I plan X{(x1=1, x2=0, x3=0)= plan A1, use 32# engine oil namely (X1=0, x2=1, x3=0)= plan A2, use liquid of homebred and new-style cutting namely (X1=0, x2=0, x3=1)= plan A3, c(X) of function of Q(X) of function of the quality in decision-making cause system, cost mixes the cutting liquid that uses an entrance to synthesize evaluation of function of cutting fluid target to be made according to facing green namely the environment affects what function E(X) includes to disclose content (ginseng see figure above) , the comprehensive assessment system of the program of fluid of 3 kinds of cutting that establishs next watch place to show. In decision-making process, use faintness to get together kind of method is right 3 targets function undertakes be evaluatinged integratedly, get quantified evaluation result, optimize a result finally with what this reflects 3 kinds of plan. This comprehensive assessment system includes 3 evaluations field, each evaluation respect contains many evaluations element, each evaluation element contains different evaluation element again. Element of each evaluation respect, evaluation and evaluation element configure different weight respectively, evaluation grade can be set for same amount order and degree, namely V={v1, v2, v3} , write down respectively for: Good / general / poor. Of decision-making model decision-making model is narrated to establish a method before building a foundation, the cutting fluid that can build this applied example chooses a model integratedly to be as follows: To X=[x1, x2, x3](x1, x2, x3=0 or 1) , beg a X*=[x1* , x2* , x3*] , satisfy tie requirement: X1* + X2* +x3*=1, make Optimum[Q(X) , c(X) , e(X)]=[Q(X*) , c(X*) , e(X*)] . The ambiguous evaluation basis of plan of fluid of 3 kinds of cutting is decision-making model, build decision-making variable to evaluate element market to plan of fluid of 3 kinds of cutting respectively, undertake blurring evaluating. Plan A1 (uses oil of cutting of 32# engine oil) build cutting fluid mass () of lubricant function of U11 U11={u1(of market of Q) evaluation element, ) of U2(cool performance, u3(cleans function) , u4(uses cycle) }11 builds cutting fluid mass (R11 of matrix of faintness of Q) evaluation element checks a method according to major and combinative expert investigates a method, with subject degree express ambiguous matrix, reach cutting fluid quality (the R11 of ambiguous evaluation matrix of Q) evaluation element is R11=[0. 50.
