| چکیده | ||
| HEPCO is an Iranian corporation that manufactures construction equipment and holds a supply chain with a traditional, non-integrated approach. The materials come from four different sources, including an engineering and parts company, domestic vendors, international vendors, and the company itself supplying the materials and components needed for assembling of products and delivering to customers. Having a non-integrated supply chain has led to an increase in total cost. Therefore, in order to reduce supply chain cost in this company, a three-level model including suppliers, manufacturers, and customers was used. Different ways also were applied to minimize chain cost, including purchase cost, transportation cost, inventory cost, assembly cost, and shortage cost, based on an integer linear mathematical model. It also considered such constraints as balance inventory, assembly capacity, storage capacity, amount of safety stock, and shortage, which were solved by MATLAB software. The results of proposed model were compared with the actual amount of variables in the study period, which indicated a significant reduction in the cost of proposed model comapred to the conventional methods. | ||

| چکیده [English] | ||
| شرکت هپکو بعنوان یک شرکت شناخته شده تولیدکننده ماشین آلات راهسازی، مواد و قطعات مورد نیاز خود را از چهار منبع جهت مونتاژ محصولات و تحویل به مشتریان تامین می کند. یکپارچه نبودن زنجیره تامین این شرکت باعث افزایش هزینه زنجیره شده است. در این مقاله، با بررسی های انجام شده مبتنی بر پژوهش های علمی به منظور کاهش هزینه های زنجیره تامین با یکپارچه سازی آن از یک مدل سه سطحی شامل تامین کنندگان، تولید کنندگان و مشتریان استفاده شده است. به منظور کمینه کردن هزینه های زنجیره شامل هزینه های خرید، حمل و نقل، نگهداری، مونتاژ و کمبود، یک مدل ریاضی خطی عدد صحیح با در نظرگرفتن محدودیتها ارائه شده که این مدل با نرم افزار MATLAB حل شده است. با اجرای مدل پیشنهادی در شرکت هپکو و تمرکز بر پارامترهای موثر بر کاهش هزینه های زنجیره تامین این شرکت به میزان قابل ملاحظه ای کاهش هزینه خواهد داشت. | ||
