چکیده
امروزه ارائه‌دهندگان خدمات به بیماران سرپایی با فشار برای کاهش هزینه‌های جاری و افزایش کیفیت خدمات رو‌به‌رو هستند. یکی از بخش‌های ارائه‌دهنده خدمات به بیماران سرپایی، بخش همودیالیز است که با منابع و تجهیزات گران‌‌قیمتی رو‌به‌رو است. لذا در مقاله حاضر، زمانبندی بیماران همودیالیز با درنظر گرفتن ترجیحات آنها مورد بررسی قرار گرفته است. هدف از زمانبندی بیماران همودیالیز در این پژوهش، کمینه‌سازی مجموع وزنی نرمال شده انحراف از ترجیحات بیماران و مجموع زمان تکمیل آنها است. لازم به‌ذکر است که ترجیحات بیمار شامل تخت، ترکیب روزهای درمانی و نوبت آنها می‌شود. برای حل مسئله، دو مدل ریاضی ارائه شده است. کارایی مدل‌های ارائه شده با توجه به اطلاعات واقعی که از بخش همودیالیز بیمارستان امام خمینی(ره) کرمانشاه گرفته شده، بررسی شده است. نتایج گویای کارایی روشهای ارائه شده در رعایت کردن ترجیحات عنوان شده از بیماران بوده اما رعایت ترجیحات بیماران در برنامه بیمارستان به‌صورت موردی و در‌صورت امکان لحاظ کردن ترجیحات، انجام شده است. به‌طوری که می‌توان گفت این ترجیحات در برنامه‌ریزی بیمارستان در اولویت قرار نداشته است. این در‌حالی است که علاوه بر رعایت ترجیحات، در جواب مدل‌ها، مجموع زمان تکمیل درمان بیماران نیز کاهش یافته است. همچنین یکی از مدل‌های ارائه شده در این مقاله قادر است مسائل با ابعاد حدود سه برابر بیمارستان مورد مطالعه را در مدت‌زمان کمی به‌طور بهینه حل کند.

چکیده [English]
Nowadays, outpatient providers are struggling to reduce the current costs and improve the service quality. A part of the outpatient service provider is a hemodialysis department with expensive supplies and equipment. Therefore, in the present paper, the scheduling of hemodialysis patients with their preferences has been studied. The aim of scheduling hemodialysis patients in this study is to minimize the normalized weighted sum of deviations from the patients' preferences and the total completion time. It should be noted that the patient's preferences include beds, treatment combination of days and their turn. To solve the problem, two mathematical models have been presented. Performence of the models in solving the real data of the hemodyalisis department of Imam Khomeini Hospital, in Kermanshah, was investigated. The results showed the efficiency of the proposed models in considering the preferences of patients; however, these preferences in the hospital schedule were considered in few cases, as far as it was possible. So, these preferences has no priority in the hospital schedule. In addition to considering the patients’ preferences, the solution of models reduced the total completion time of the pationts treatment. Also, one of the proposed models in this papercould optimally solve the instances three times larger than the hospital cases
