This paper studies the target visitation arc routing problem on an undirected graph. combines well-known rural postman and linear ordering problem. In this problem, there is a set of required edges partitioned into targets, which must be traversed are pairwise preferences for order in some targets serviced, generates revenue if preference satisfied. The aim to find tour that traverses all at le...

This paper introduces the fish feed production routing problem (FFPRP) faced by Norwegian salmon producers. The FFPRP is comprised of a scheduling and rich vehicle (VRP) thus denotes variant integrated problem. We present discrete time mixed integer programming (MIP) model FFPRP. Specifically, incorporates multi-product, multi-trip, multi-depot setting, where orders are produced at lines factor...

Generally, the inventory routing problem occurs in a supply chain where customers consider the supplier responsible for inventory replenishment. In this situation, the supplier finds the answer to questions regarding the time and quantity of delivery to the customer as well as the sequence of customers in the routes. Considering the effect of production decisions on answering these questions, t...

in this paper, we study the multi-depot vehiclerouting problem with inter-depot routes, in which the vehicles can replenish atintermediate depots. vehicles leave the origin depot with load on-board andserve customers until out of load. they may visit an intermediate depot toreplenish and finally return to the origin depot, completing their route. weinitiate a mathematical mixed integer programm...
