[ 1 ] - یک الگوریتم ترکیبی اصلاحی مورچگان برای حل مساله مسیریابی وسیله نقلیه باز ظرفیتدار
مساله مسیریابی وسیله نقلیه (VRP) شامل مسیریابی برای یک ناوگان وسیله نقلیه برای سرویسدهی به تعدادی مشتری است که در آن هدف کمینهسازی فاصلههای پیموده شده توسط همه وسائل نقلیه است. در این مساله وسایل نقلیه باید بعد از انجام کامل خدمات به انبار کالا بازگردند. مساله مسیریابی وسیله نقلیه باز (OVRP) با اکثر نسخههای مسائل مسیریابی وسیله نقلیه در ادبیات موضوع متفاوت است و در آن وسائل نقلیه بعد از انج...
[ 2 ] - An Improved Modified Tabu Search Algorithm to Solve the Vehicle Routing Problem with Simultaneous Pickup and Delivery
The vehicle routing problem with simultaneous pickup and delivery (VRPSPD) is a well-known combinatorial optimization problem which addresses provided service to a set of customers using a homogeneous fleet of capacitated vehicles. The objective is to minimize the distance traveled. The VRPSPD is an NP-hard combinatorial optimization problem. Therefore, practical large-scale instances of VR...
[ 3 ] - A Hybrid Modified Meta-heuristic Algorithm for Solving the Traveling Salesman Problem
The traveling salesman problem (TSP) is one of the most important combinational optimization problems that have nowadays received much attention because of its practical applications in industrial and service problems. In this paper, a hybrid two-phase meta-heuristic algorithm called MACSGA used for solving the TSP is presented. At the first stage, the TSP is solved by the modified ant colony s...
