چکیده مقاله :
برنامه ریزی فروش و عملیات[1] امروزه به یک فرایند شناخته شده و پرکاربرد در زنجیرۀ تأمین تبدیل شده است. با این حال تا به امروز، ارزیابی و محاسبه منافع بکارگیری این فرایند مورد غفلت قرارگرفته است. این مقاله، عملکرد فرایند برنامه ریزی فروش و عملیات را از طریق مدل سازی ریاضی مورد ارزیابی قرار می دهد. در این مطالعه، سه مدل برنامه ریزی مختلط اعداد صحیح[2] ارائه شدند که به ترتیب نشان می دهنده: "برنامه ریزی فروش و عملیات کاملاً یکپارچه[3]" که در آن برنامه ریزی فروش، تولید، توزیع و تأمین بصورت متمرکز و یکپارچه انجام می پذیرد؛ "برنامه ریزی فروش و عملیات نسبتاً یکپارچه[4]" که درآن برنامه ریزی فروش و تولید بصورت متمرکز انجام گرفته، درحالی که برنامه ریزی توزیع و تأمین بصورت مجزا در هر سایت انجام می گیرد؛ یک مدل "برنامه ریزی گسسته[5]" که در آن برنامه ریزی فروش به صورت متمرکز انجام شده، در حالی که برنامه ریزی تولید، توزیع و تأمین به صورت مجزا و محلی انجام می گیرد. هرسه مدل مذکور برای یک سیستم تولیدی چندسایتی توسعه داده شده اند که دارای تأمین کنندگان متعدد بوده، محصولات متفاوتی را تولید می کنند و به مشتریان بسیاری سرویس می دهند. در انتها، عملکرد برنامه ریزی فروش و عملیات کاملاً یکپارچه نسبت به دو مدل دیگر، از طریق مقایسه تأثیرات مالی این رویکردها تحت تقاضای ماهانه و قیمت بازار واقعی دریک شرکت تولید صنایع فرمینگ[6] در ایران مورد ارزیابی قرار گرفته است. نتایج، بیانگر برتری مدل برنامه ریزی کاملا یکپارچه نسبت به دو مدل دیگر است.

Nowadays, Sales and Operations Planning has become a well-knownand widely used process, yet, up to now, its usefulness has beenneglected. This paper intended to assess the performance process of saleand operation planning through mathematical modelling procedure.Three Mixed Integer Programming (MIP) models have been developedin this study, namely fully integrated (with centralized sales, production,distribution and procurement planning), partially integrated (withcentralized sales and production, but separated procurement anddistribution planning), and decoupled (with centralized sales, butdecentralized production, distribution and procurement planning). Allthree models have been developed for a multi-site manufacturingcompany. The results demonstrated the superiority of fully integratedmodel over the others.
