چکیده

یکی از فاکتورهای مهم در مدیریت زنجیرۀ تأمین، انتخاب تأمین‌کنندۀ مناسب است، به‌طوری‌که تصمیم‌گیری صحیح در این مورد سبب کاهش هزینه‌های خرید، ایجاد رابطۀ پایدار با تأمین‌کننده‌ها و تقویت استراتژی رقابتی در بازار می‌شود. در این مقاله ابتدا با بررسی مقالات مرتبط، معیارهای مهم در امر انتخاب به‌دست آمد و سپس با روش دلفی فازی، وزن­دهی معیارها و ارزیابی گزینه‌ها انجام گرفت. با رتبه‌بندی گزینه‌ها به‌روش تاپسیس فازی، پنج آستانه به‌دست آمد که با استفاده از این آستانه‌ها می­توان گزینه‌ها را به چهار دستۀ درجه یک، درجه دو، درجه سه و نامناسب تقسیم کرد. نتایجی که تا این مرحله به‌دست آمد، به دانش و قوانین سیستم خبرۀ پیشنهادی تبدیل شد. با استفاده از پوستۀ سیستم خبرۀ جاوا، طراحی و پیاده­سازی سیستم، طوری انجام گرفت که در آینده هم بتوان پایگاه دانش آن را بهنگام کرد. برای ایجاد یک رابط گرافیکی کاربر­پسند از زبان جاوا کمک گرفته شد. سیستم پیشنهادی و افراد خبره، جداگانه چندین نمونه را ارزیابی کردند که پس از مقایسه، نتایج به‌طور قابل­قبولی به هم نزدیک بودند.

چکیده [English]

Suitable supplier selection is the most important factor in supplier chain management; so that correct decisions in this phase, caused to reduce costs, make permanent relationship with suppliers and strong competitive strategy in market. In this paper, by reviewing the past articles, important related criteria found and then weighting of criteria and evaluation of alternatives were done with fuzzy Delphi. By ranking the alternatives in fuzzy TOPSIS, five thresholds obtained for grouping in the future. The results that obtained from these computations, converted to knowledge base (KB) of Expert System for Supplier Evaluation (ESSE). The ESSE was designed in Java Expert System Shell (Jess), so that its KB could be updated in the future. To make a user friendly interface, java language was used. The proposed system and experts individually evaluated some sample alternatives and by compare the results, they were very close.
