To better demonstrate the relations among the indexes , they are treated by fuzzy processing method and their weights are calculated 計(jì)算各個(gè)指標(biāo)相對(duì)重要程度,即確定各指標(biāo)的權(quán)重。
By considering both fuzzy processing time and fuzzy due date as well as specific operator of the workpiece with alternative machines , a fuzzy job shop scheduling problem with alternative machines was studied 摘要在車間實(shí)際加工中,工件的加工時(shí)間和交貨期是一個(gè)模糊數(shù),而且工件的某道工序有多臺(tái)機(jī)器可供選擇。
Through analyzing the model by applying fuzzy mathematics extension principles and the properties of jobs with fuzzy processing times , the optimal solutions of the problem are presented under some special cases , and a necessary condition of optimal solution is given under the general case 通過(guò)模糊數(shù)學(xué)知識(shí)對(duì)模型進(jìn)行分析,對(duì)于特殊情況給出了問(wèn)題的最優(yōu)解,對(duì)于一般情況給出了一個(gè)最優(yōu)解的必要條件。
Take the laser diode as the photoelectric detector ' s lamp - house , the optical system forms images of the sign , the double photoconductive resistance detects the excursion of the sign , a / d converter finishes a / d convert , the data is fuzzy processed by micro computer 光電探頭采用激光二極管作為光源,光學(xué)系統(tǒng)完成標(biāo)志的成像,雙光敏電阻檢測(cè)標(biāo)志線的偏移, a / d轉(zhuǎn)換器完成偏移信號(hào)的模數(shù)轉(zhuǎn)換,數(shù)據(jù)由微機(jī)進(jìn)行模糊處理。
Firstly , a new cost - tolerance model , which closely links with real technological process , is built using fuzzy neural networks . the influence of process factor on the manufacturing cost is analysed and a fuzzy process factor is introduced using fuzzy mathematics principle . then fuzzy neural network is applied to modelling of production cost - tolerance model 首先研究了面向制造環(huán)境的公差-成本模型,對(duì)加工因素進(jìn)行模糊化處理,建立了加工因素的模糊影響系數(shù),并以此系數(shù)和零件公差作為輸入,建立了基于模糊神經(jīng)網(wǎng)絡(luò)的公差-成本模型。
According to the diagnostic characteristic of the interior fault in transformer , we study the fault diagnostic of transformer by fat , es , ft . the main achievement lies in below : 1 , constructing the transformer model of diagnostic fault apply in fat with help of the data of actual transformer fault during several years and applying in transformer fault diagnostic expert system . 2 , dissolved gas - in - oil analysis is done fuzzy process 針對(duì)變壓器內(nèi)部故障診斷特點(diǎn),運(yùn)用故障樹分析技術(shù)、專家系統(tǒng)方法和模糊數(shù)學(xué)理論對(duì)變壓器故障診斷技術(shù)進(jìn)行了研究,主要的成果在于以下幾個(gè)方面: 1 ,通過(guò)對(duì)近年來(lái)大型電力變壓器故障實(shí)例做出分析,用故障樹分析法( fat ) ,建立變壓器故障樹診斷模型,并把它運(yùn)用到變壓器故障診斷的專家系統(tǒng)中。
The inputs of the network are tolerance and fuzzy process factor and the output is manufacturing cost . secondly , taguchi ' s quality loss function is a simple quadratic symmetric style , the paper expands it a fuzzy quality loss model using fuzzy theory . a concept of fuzzy quality loss and fuzzy quality loss cost are first presented 然后應(yīng)用模糊理論對(duì)田口二次型質(zhì)量損失模型進(jìn)行拓展,提出了模糊質(zhì)量損失和模糊質(zhì)量損失成本的概念,由此建立了模糊質(zhì)量損失模型,并研究了多質(zhì)量特性時(shí)模糊質(zhì)量損失成本的計(jì)算方法。
