6、的人員,從而不能滿足現代工業(yè)生產的需求。為了提高生產效率很必有要引進CNC機器和機器人生產線,同時還能增強生產線能力。因此,應該改善生產線機器設備布局來確保產量并且應該事先預測最大可能的產量。因此,建議使用SLP法對于生產線布局改善設計。SLP法用于確定生產過程中最優(yōu)的設備布局和工藝布局。使用SLP法進行布局改善設計已經在一個生產管道的特定造船車間經過測試。</p><p>  關鍵詞:管道生產車間;生產線布局設

20、the old ones have to be technologically rearranged, which is usually difficult to realize. That is the reason why the best solution might be to design a completely new production line if possible.</p><p>  當

21、在一個工廠設計一個全新的生產線時空間是一個大的問題,因為建立生產線需要空間,所以新的空間需要被發(fā)現否則就要對舊的生產線進行改進,這是個很難實現的問題。這就是為什么最好的生產線建設方案就是在沒生產線的空白車間進行全新的設計,因為不需要考慮空間問題。</p><p>  The layout design has a significant impact on the performance of a product

29、計過程中得以實現。對于這些方法,設計流程被分成幾個步驟,然后按照順序進行解決。成功的設計方案常常出自經驗豐富的設計師曾設計的方案的代代傳承。因此在進行生產線布局時采用專家的方法進行設計是必須的。它常常是進行設計布局評估的最后一個步驟。因為如果采用多個目標函數值進行設計最終方案的選擇將是很難的一個步驟。</p><p>  A workshop layout design problem exposes the s

37、oviding a brief review of the SLP procedure as shown in Figure 1. The SLP begins with PQRST analysis (step 1) for the overall production activities. The data collection fields including P (product),Q (quantity), R (routi

38、ng), S (supporting), and T (time) should be scrutinized in order to assure the validity of the</p><p>  input data at the design stage. </p><p>  本節(jié)重點對SLP法的理論和實施方法進行介紹,大體概況如圖1所示:SLP法從對生產線進行全

39、面分析的PQRST開始。對收集到的數據包括P(產品)、Q(產量)、R(生產路線)、S(輔助服務部門)、T(時間)應進行細致的審核,以確保輸入參數的有效性。</p><p>  Figure1.SLP procedure</p><p>  圖1 SLP法實施程序圖</p><p>  In the flow of material analysis (step 2

40、), all material flows from the whole production line are aggregated into a from-to chart that represents the flow intensity among</p><p>  different tool sets or work positions. The step of “activity relatio

41、nships” (step 3) performs qualitative analysis towards the close relationship decision among different</p><p>  work positions.</p><p>  在第二步物流分析里所有生產線的物料流動都被統(tǒng)計到一個代表不同工位或者不同工作地點物流強度的從致表中。第三步作業(yè)相關

42、關系分析表明了不同工作之間的相關關系。</p><p>  The step of “relationship diagram” (step 4) positions areas spatially. For those work positions (areas) that have strong interactions and/or close relationships are placed in pro

43、ximity.</p><p>  第四步用相關關系圖將各工序的相關關系表示出來。對于那些具有很強的相互關系或者很近的作業(yè)關系的工序設備擺放在一起。</p><p>  The steps of “space requirements” and “space available” (steps 5 and 6) determine the amount of floor space to

44、be allocated to each work position. This decision is particularly critical to a workshop design problem due to the costly clean room floor space and the difficulty in future expansion.</p><p>  第五步和第六步“需要的空間

45、”和“可以利用的空間”決定了可以供給每個工序設備所使用的空間。這一決策對空間設備布局非??量?,因為車間空間的巨大價值和未來車間擴張的需要決定了車間空間的利用價值。</p><p>  The step of “space relationship diagram” (step 7) adds area size information into the relationship diagram from step

46、 4. Additional design constraints and limitations are</p><p>  considered before the start of block layout generation in steps 8 and 9. Step 10 then develops layout alternatives as design candidates. Step 11
