Abstract    Enhancing the speed and contest in an exhibition of services and products motivate the companies to exposure high quality products to customers. One of the effective ways to reach these goals is to create working groups that can help the companies to improve quality and exposure of services and products and reduce the costs. This approach is practical in the healthcare area as well. Group buying is one of the main strategies that many healthcare institutes are trying to control the costs and quality of the stuffs by it. In this study, considering the objectives of procurement costs, distance of drugstores and the members interest to be in a purchasing group is proposed. To optimize the model objectives simultaneously, an LP-Metric goal programming approach is utilized. Finally, the case study of drug's group buying is presented to show the proposed model effectiveness.

چکیده    افزایش سرعت و رقابت در ارائه خدمات و محصولات، شرکت‌ها را برای ارائه محصولات با کیفیت به مشتریان برمی‌انگیزد. یکی از راه‌های موثر برای رسیدن به این اهداف، ایجاد گروه‌های کاری است که می‌توانند شرکت‌ها را در بهبود کیفیت محصولات و خدمات و کاهش هزینه‌ها یاری نماید. این رویکرد در حوزه بهداشت و درمان نیز عملی است. خرید گروهی یک استراتژی مهم است که بسیاری از موسسات بهداشتی و درمانی با کمک آن به دنبال دستیابی به مهار هزینه‌ها و بهبود کیفیت کالاهای خریداری شده‌اند. در این مطالعه تشکیل گروه با توجه به اهداف هزینه‌های خرید، فاصله داروخانه‌ها و علاقه‌مندی اعضاء ارائه شده است. به منظور بهینه سازی اهداف، از رویکرد برنامه‌ریزی آرمانی LP-Metric استفاده شده است. در پایان، مطالعه موردی خرید گروهی داروها برای نشان دادن کاربرد و اثربخشی مدل مربوطه ارائه می‌شود.
