Abstract :
This paper integrates competitive pricing and network design problems for the short life cycle
products. The pricing problem determines selling prices of the products for different life cycle phases
in a competitive market, as well as acquisition management of returned products. Besides, the selling
and acquisition prices are related to the distance between distribution centers and customers. The
network design problem aims to determine network flow and fleet assignment in each route. The
proposed model is solved by various methods including exact and meta-heuristic approaches. The
model and solving approaches have been validated and verified by several simulated examples and
sensitivity analyses. Considering life cycle phases, competitive pricing, and transshipment problems
as an integrated model, provides a new approach for the optimum solutions, which makes it more
practical for application of real cases of short life cycle products. The results showed how the
competition and fleet assignment influenced the optimum solution.

در اين تحقيق به مسائل قيمت گذاري در شرايط رقابتي و طراحي شبكه زنجيره تأمين محصولات با چرخه عمر كوتاه به صورت يكپارچه پرداخته شده است. در بخش قيمت گذاري، مدل پيشنهادي قادر است قيمت فروش محصولات را در
چرخه عمرشان به كمك محاسبه تابع پاسخ منطقي بازار تحت شرايط رقابتي تعيين كند. در بخش طراحي فازهاي مختلف شبكه، ميزان مراودات بين تسهيلات مختلف زنجيره رفت و برگشت و همچنين تخصيص ناوگان حمل و نقل به هر مسير بهينه سازي مي گردد. تخصيص ناوگان بهينه تأثير به سزايي در بهينه سازي و نزديك نمودن مدل به واقعيت خواهد داشت. مدل پيشنهادي با استفاده از روشهاي مختلفي شامل روشهاي دقيق و فرا ابتكاري حل شده است. روشهاي فرا ابتكاري مورد استفاده شامل يك الگوريتم كلاسيك (الگوريتم ژنتيك)، يك الگوريتم جديد (الگوريتم بهينه سازي نهنگ) و همچنين ارائه يك الگوريتم تركيبي جديد است.
