چکیده

در طراحی استراتژی سطح بنگاه، انتخاب سبد کسب‌و‌کار یکی از تصمیم­های کلیدی به شمار می‌رود که با موضوعاتی نظیر ادغام عمودی و متنوع ­سازی در ارتباط است. اکثر پژوهش‌های پیشین، مدل‌های کلان و مفهومی در این خصوص ارائه داده­ اند و یا با رویکردهای صرفاً مالی بر روش ­های بهینه ­سازی سبد سرمایه­ گذاری­ ها مبتنی بوده­ اند. در این پژوهش یک مدل ریاضی برای انتخاب سبد کسب‌و‌کار ارائه شده است که امکان بهره­ گیری از روش­ های کمی در تصمیم­ گیری ­های استراتژیک در این حوزه را فراهم می ­آورد و همچنین، متغیرهای غیرمالی و استراتژیک را نیز در مدل‌سازی مسئله در نظر می­ گیرد. برای این منظور چهارچوبی ریاضی برای لحاظ تأثیر هم ­افزایی میان کسب‌و‌کارها پیشنهاد شده و مدل‌سازی در قالب یک زنجیره ارزش توسعه یافته است. هرچند ساختار مفهومی طراحی‌شده قابل‌استفاده برای صنایع مختلف است، در این پژوهش مدل‌سازی برای یک بنگاه چندکسب‌و‌کاره فعال در صنعت نفت ایران انجام شده و توسط الگوریتم ژنتیک حل شده است.
