One of the important aspects of distribution optimization problems is simultaneously, controlling the inventory while devising the best vehicle routing, which is a famous problem, called inventory-routing problem (IRP). When the lot-sizing decisions are jointed with IRP, the problem will get more complicated called production inventory-routing problem (PIRP). To become closer to the real life p...

This paper introduces the Cyclic Production Routing Problem (CPRP). The CPRP is an extension of well-known NP-hard (PRP), which a hard-to-solve combinatorial optimisation problem with numerous practical applications in field freight transportation, logistics and supply chain management. Under PRP setting, manufacturer responsible for determining production decisions, as well timing quantity rep...

flood is one of the major natural disasters in iran, which is mostly, affected most parts of the country and caused hazards. therefore, identification of the area with high potential risk of flood occurrence is the main purpose in order to the flood control and reducing its damages. in this research the role of the flood routing in identification of the area with high potential flooding has inv...

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...

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...

The emergence of locally produced renewable energies induces the appearance a new generation local energy players, which are at same time producers and consumers. In case dependent solar production, it raises question synchronizing production consumption. We deal here with this issue, in context an experimental Solar Hydrogen (H 2 ) platform. More precisely, we try to simultaneously schedule H ...

in the recent decade, special attention is paid to reverse logistic due to economic benefits of recovery and recycling of used products as well as environmental legislation and social concerns. on the other hand، many researches claim that separately and sequential planning of forward and reverse logistic causes sub-optimality. effective transport activities are also one of the most important c...

Transportation in economic systems such as services, production and distribution enjoys a special and important position and provides a significant portion of the country's gross domestic product. Improvements in transportation system mean improvements in the traveling routes and the elimination of unnecessary distances in any system. The Vehicle Routing Problem (VRP) is one of the practical co...

The production routing problem (PRP) combines the lot-sizing problem and the vehicle routing problem, two classical problems that have been extensively studied for more than half a century. The PRP is solved in an attempt to jointly optimize production, inventory, distribution and routing decisions and is thus a generalization of the inventory routing problem (IRP). Although the PRP has a compl...
