Environment 0 1 1 0 2
Economical 0 0 1 1 2
Aesthstic 1 0 0 1 2
Technology 0 1 0 0 1
Decision-maker in step S1, i.e. carries out information processing and " people " of information feedback or by people to a certain decision object Composition all kinds of groups, mainly include user, planner, planning teacher, architect, government department, developer, investor, its His expert and the relevant main body of interests, need to define respectively in different scheme programs.Can be judged by following manner should The weight of decision object to which kind of decision-maker tilts:
If the interests composition ＜ technological component of decision object, weight tilts to expert.This decision object mainly has 1) merit Energy key element, including function composition, spatial shape etc.；2) format factor, including architectural scale, form, color etc.；3) economy is wanted Element, including investment operation cost, income etc.；4) element of time, including construction period, useful life etc.；5) ecological key element, including Environmental effect, utilization of energy etc.；
Decision object for interests composition >=technological component, it is necessary to decomposition further to decision object.For public character The situation of interests ＜ property benefits, weight tilts to interested party.This decision object is mainly and reclaims benefit, construction The decision object that cycle, service life, maintenance cost are correlated with.
When public character interests >=property benefits, it is necessary to consider another problem: the approval demand of project.If Approval demand is high, then weight tilts to the public；If approval demand is low, then weight tilts to government.
In step S3, different decision-makers are all to adopt for each decision object the decision weights of each decision object The decision weights of each decision-maker is obtained by expert's enabling legislation, particularly as follows:
(301) marking index is set and determines each marking index weights Pi, i=1,2 ... n, n are total of marking index Number；
(302) multiple experts carry out marking to each decision-maker according to the marking index in step (301) and are beaten Score value, remembers IjkiMarking value kth decision-maker obtained according to i-th marking index for jth expert, wherein j=1, 2 ... m, m are the total number of expert, k=1,2 ... q, q are the total number of decision-maker；
(303) jth expert is asked for respectively according to following formula to kth decision-maker totally marking value:
Ijk=P1Ijk1/(Ij11+Ij21+…Ijq1)+P2Ijk2/(Ij12+Ij22+…Ijq2)+…PnIjkn/(Ij1n+Ij2n+… Ijqn)；
(304) decision weights of kth decision-maker is asked for respectively according to following formula:
W k = Σ j = 1 m I j k Σ j = 1 m Σ k = 1 q I j k .
Step S4 particularly as follows:
(401) it is that each decision object arranges different decision schemes, and is designed to questionnaire, every in questionnaire One topic corresponds to a kind of decision object, and the option in each topic corresponds to a decision scheme；
(402) all decision-makers participate in the answer of questionnaire, and according to decision-maker statistics, each option is chosen this choosing The decision-maker of item accounts for the ratio of the total personnel of this decision-maker, thus respectively obtains kth decision-maker to each decision scheme Preference value Kk, k=1,2 ... q, q are the total number of decision-maker.
Step S5 particularly as follows:
For a concrete decision scheme, its decision value M is obtained by following formula:
M = Σ k = 1 q K k · W k ,
Wherein, k=1,2 ... q, q are the total number of decision-maker, KkFor kth decision-maker pair in this decision scheme Preference value, WkThe decision weights of kth decision-maker corresponding in this decision scheme.
Step S6 produce decision-making report after can by Preliminary design Proof of Concept report correctness, if decision-making report with Preliminary design concept is inconsistent, then need to repeat step S1～S6 until consistent with Preliminary design concept, now produce Decision-making report is final decision report.
Decision method of the present invention is specifically introduced as a example by workman Village, Shanghai City " reassuring the old in former residence " improvement and design construction project Implementation process:
First, carry out the item base analysis of workman Village, Shanghai City " reassuring the old in former residence " improvement and design architectural programming, understand Its background, type of identifying project, to be familiar with relevant decision-making problem, analysis project key feature, determines workman Village, Shanghai City " reassuring the old in former residence " improvement and design project objective.
Then, it is determined that decision object, the decision object of the suitable old transformation in workman Village include objective reality affect object and Need the decision object made a policy.Object will be affected and decision object is separated, extract decision object: affect what object referred to It is that old transformation suitable on workman Village exists the object of impact, including current workman Village not by manual control and objective reality Minimum distance for sunlight between house, the site coverage of community, green percentage, road network etc..Decision object refers to according to decision-maker certainly The object that body interests demand, subjective judgment make a policy, in workman Village, suitable old transformation includes the transformation demand of cell environment, The transformation demand of monomer and house type, the demand etc. of suitable old service, also include the investment budgey during transformation, construction period simultaneously Demand, it follows that above-mentioned decision object is screened again and processes, and compare that to obtain the decision-making of decision object strong one by one Degree, thus carry out significance level sequence, in this embodiment, decision object is divided into for following several classes: Gong Renxin by significance level order Village's residential envirronment, workman Village single residence fit aging design, the suitable old service in workman Village, workman Village suitable old transformation economic week Phase.
Next decision-maker is analyzed, obtains decision-maker weight and the organizational form to decision-maker.At this In example, first, decision-maker be defined as old people (age in workman Village that hangs up one's hat 60 years old and above crowd, Be specifically divided into the most again old man 1. 60-69 year, old man 2. 70-79 year, old man 3. 80 years old and more than), (age is 60 for young people Year following temporarily or hang up one's hat the crowd in workman Village), government, expert and scholar.After trade-off decision type of subject, respectively Being its configuration decisions weight according to different decision object: for residential envirronment, the property benefits composition of resident is more than political affairs Mansion public character interests composition, then for resident and government, weight tends to resident, and technological component is more than public interest composition, then For government and expert, weight tends to expert.Then according to the subjective weights mode of architectural programming group decision, draw old man's Weight is 0.2, and young people's weight is 0.12, and experts and scholars' weight is 0.18, and government department's weight is 0.1；For house list For body, the property benefits composition of resident is more than government's public character interests composition, then for resident and government, weight is tended to Resident, and technological component is more than public interest composition, then for government and expert, weight tends to expert.Then according to building plan Drawing the subjective weights mode of group decision, show that the weight of old man is 0.2, young people's weight is 0.12, and experts and scholars' weight is 0.18, government department's weight is 0.1.(building elevator and heating system selects in this decision-making of two about adding, technological component is the most remote More than public interest composition, therefore this part is set to 0.2 old man's weight, and young people's weight is set to 0.15, and experts and scholars weigh Being reset to 0.2, government department's weight is set to 0.05)；For suitable old service, the property benefits composition of resident is more than government Public character interests composition, then for resident and government, weight tends to resident, and public interest composition is more than technological component, then political affairs For mansion and expert, weight tends to government.Then according to the subjective weights mode of architectural programming group decision, the power of old man is drawn Being heavily 0.2, young people's weight is 0.12, and experts and scholars' weight is 0.1, and government department's weight is 0.18；For economic cycle For, property benefits composition and government's public character interests composition of resident are more or less the same, and interests composition is more than technological component, Then for resident and government and expert, weight tends to resident and government.Then according to the subjective weights side of architectural programming group decision Formula, show that the weight of old man is 0.15, and young people's weight is 0.15, and experts and scholars' weight is 0.1, and government department's weight is 0.3。
It follows that all use the mode providing questionnaire face to face to add up preference value this four classes decision-maker.In this example, right Decision-maker has provided altogether 312 parts of effective questionnaires, has added up result of answering, as a example by partial group decision value calculates:
First entitled multiple choice, entitled: for old man, what not all right road was inconvenient has which？Option in this exercise question Including: A pavement mixes with driveway, and B is narrow, and inconvenience wheelchair uses, and C exists high step, barrier, the out-of-flatness of D roadside, slides Wet, E other.Statistical result showed has the old man of 72.64% 1. to have selected option A, and therefore 0.7264 to refer to decision-maker old People's 1. option score value to A, i.e. K1, by that analogy, old man 2., old man 3., government, the young and the middle aged, expert's score K to option A2 ～K6Being respectively 0.7419,0.7963,0.8947,0.7234,0.6, correspondingly, this problem belongs to residential envirronment part, therefore The weight of the main body each for residential envirronment part that corresponding step S3 is drawn: W1=W2=W3=0.2, W4=0.12, W5= 0.18, W6=0.1, substitute into formula, M=K1×W1+K2×W2+……+K6×W6, decision value M=0.7264 × 0.2+ can be obtained 0.7419 × 0.2+0.7963 × 0.2+0.8947 × 0.12+0.7234 × 0.18+0.6 × 0.1=0.7372.By that analogy, Calculating the decision value of other option, the decision value of corresponding B option is 0.3387, and the decision value of C option is 0.2906, D option Decision value be 0.3518, the decision value of E option is 0.1064.
By that analogy, the decision value of each option in all exercise questions is calculated.As entitled for old man in the second topic, live What residence unit gateway was inconvenient has which？Option A is not provided with accessible ramp, and the option B step discrepancy in elevation is excessive, option C step Place is not provided with handrail, and option D easily slips on ground, option E other.The decision value of option A～E is followed successively by 0.3697, 0.2352、0.3310、0.2494、0.3217；In like manner, the 3rd topic is entitled for old man, and outdoor activity space is inconvenient Which has？Option A activity space lacks, and option B activity space is taken by automobile, bicycle etc., lacks in option C activity space Few privacy, lacks accessibility designs in option D activity space, option E other.The decision value of option A～E is followed successively by 0.6413, 0.7544、0.0862、0.2524、0.0634。
Finally, according to the solving result of decision value and the sequence of importance of decision object, it is complete, logical to produce Decision-making report.In each exercise question, each option is a decision scheme, and the option that decision value is big is in the urgent need to implementing Decision scheme, therefore, on the premise of limited budget, the decision scheme that first implementation decision value is big, less the determining of implementation decision value Plan scheme.
First entitled example, obtains height sequence according to decision value, and A option pavement and driveway mix decision value and be 0.7372, it is significantly larger than the decision value of other options, illustrating that current pavement and garage mix is distinct issues, and transformation needs Degree of asking is the highest, it should first just solving D option Uneven road, wet and slippery, B option is narrow, is not easy to wheelchair and uses decision value higher, Illustrate this part is had certain demand.C option is existed high step, and the selection of barrier is fewer in number, illustrates this part Transformation demand degree is relatively low, can delay consideration.
Can draw planning conclusion accordingly:
1. mix for A option pavement and driveway, should first carry out workman Village human and vehicle shunting system, increase and stop Bit quantity, discharges path space.
2., for the option that B and D the two demand degree is general, road-surface problem of should paying general attention, smooth-riding surface, carry out anti-skidding Measure, and carry out the barrier-free measure for wheelchair.
In like manner the second topic, the decision value of option A and option C is higher, next to that option D and the problem of option B, this four part Decision value is average, it is seen that the demand degree of transformation is similar to.
Can draw planning conclusion accordingly:
1. option A demand degree is the highest, and accessible ramp is mostly important the most urgent, should first consider to solve, workman Village arranges accessible ramp.
2.C option demand degree is higher, therefore should try one's best and arrange handrail at step.
3., under the situation of conditions permit, solve the excessive problem easily slipped with ground of the step discrepancy in elevation in B and D option, fall The riser height of low step or tread width to ground (step) anti-skidding process.
In like manner, in the 3rd topic, the decision value of option B and option A is far above other options, it is seen that the two item is currently to open Spacious space common problem, transformation demand degree is the highest.D option lacks consideration accessible in existing old people's activity space Design is also the problem existed, but not main, and transformation demand degree is general.Decision value about privacy is the lowest, and room is described Outer activity space is substantially without the transformation considered privacy.
Can draw planning conclusion accordingly:
1., for B option, reasonable arrangement parking space is the outdoor activity space transformation project needing most to solve, it should give Emphasis preferentially solves.
2., for A option, it should suitably increase activity space, existing activity space is improved, increases operation rate.
3. for D option, should on the basis of conditions permit the accessibility designs of with due regard to activity space.
By that analogy, complete decision-making report is sorted out according to the decision value of other all exercise questions.
