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.

چکیده [English]

Designing the business portfolio is a key decision in corporate-level strategy and is bonded with strategic concepts such as vertical integration and diversification. Nevertheless, most of the previous researches have proposed general conceptual models, or investment portfolio optimization models based on financial approach. In this paper, a mathematical model is proposed, firstly to utilize quantitative methods in strategic decision makings and secondly, to considers non-financial, strategic variables in modeling process. To address this need, a mathematical framework for formulating synergies between businesses in a value chain is developed. Although the conceptual structure is applicable for different industries, the model is developed for a multi-business company in petroleum industry of Iran and is solved by genetic algorithm.
