در اين مقاله، يك مدل رياضي چندهدفه چند دورهيي براي انتخاب پروژههاي سرمايهگذاري مبتني بر اهداف توسعهي پايدار با در نظر گرفتن محدوديت منابع پيشنهاد ميشود. بر اساس بعد اقتصادي پايداري، سود حاصل از اجراي پروژهها بيشينه و بر اساس بعد زيستمحيطي، ميزان انتشار گازهاي گلخانهيي، مصرف انرژي و پسماندهاي توليد شده كمينه ميشود. در بعد اجتماعي تعداد فرصتهاي شغلي، تعداد افراد تحت پوشش بيمه، رضايت شغلي كاركنان، تأثير پروژه بر اقتصاد منطقه و تعداد روزهاي از دست رفته كاري بررسي ميشود. عدمقطعيت پارامترهاي استراتژيك و عملياتي مدلنيز لحاظ شده است و براي برخورد با عدمقطعيت، از برنامهريزي فازي امكاني استفاده ميشود. مدل با يك رويكرد دو مرحلهيي مبتني بر برنامهريزي فازي و روش تصميمگيري بهترين ـ بدترين گروهي حل ميشود. نتايج عددي، كارايي مدل پيشنهادي را تأييد ميكنند و نشان ميدهند كه اهداف توسعهي پايدار، موجب بهبود چشمگير ابعاد زيستمحيطي و اجتماعي بدون كاهش قابلملاحظه سود پروژههاي انتخاب شده خواهد شد.
چكيده لاتين :
The investment project selection problem is one of the most pressing challenges confronting organization managers, and its primary goal is to assist investors in selecting the best set of projects given the circumstances of their decision-making environment. In this work, a multi-objective mathematical model is developed for choosing investment projects across a multi-period horizon based on sustainable development goals. The gains from project execution are maximized in terms of the economic dimension of the sustainability. The quantity of greenhouse gas emissions, produced waste, and energy spent to supply the needed raw materials are minimized in accordance with the environmental dimension. The number of job openings, the number of individuals covered by insurance, the work satisfaction of employees as a result of delivering welfare services, the project's influence on the local economy, and the number of days lost are all factors to consider in the social component of sustainability. Real-world limitations like machinery, labor, raw materials, and the capacity of suppliers to deliver the needed raw materials for projects are all taken into account in the suggested model. As it is seldom feasible to determine the precise value of parameters, uncertainty in the strategic and operational parameters of the project selection model is also taken into consideration. To cope with uncertainty in the model parameters, the fuzzy possibilistic programming technique is utilized. A two-stage solution technique is provided for solving the proposed model. The importance weight of environmental and social goals is calculated in the first stage using the group best-worst approach. The multi-objective mixed integer programming model is then transformed into a single-objective model using a fuzzy interactive programming in the second stage. The efficacy of the suggested model is demonstrated by numerical findings, which indicate that incorporating sustainable development goals allows investors to analyze strategic project selection decisions from three perspectives: profit, environment, and social.
