چکیده:
The main aim of this paper is to present a conceptual structure for the Maritime Inventory-Routing Problem. We have looked at the matter from the supply chain angel and summed up the key comprising elements and major hypotheses in the framework of a conceptual model. We have reviewed the related literature in detail in a classified manner, separated various issues, and eventually in accordance with the identified gaps, presented the grounds for the development of the model in the same particular framework. What we deal with in this article is in fact the zero level of the Maritime Inventory-Routing Problem while for focusing on higher levels it is possible to consider greater details by providing arithmetic models on more comprehensive navigation of naval goods in a more compact and sold manner. According to this review, most researches are deterministic at the tactical level, on the basis of discreet time and in the arc-flow framework, generally solved by exact or heuristic methods.
خلاصه ماشینی:
Among the studies in this field we can refer to articles by Hoff Et al (2010), Coelho Et al (2014) and SteadieSeifi Et al (2014), in which the authors tried to survey the issue of inventory routing from the general and public points of the view.
To do so, we have taken account of an initial framework based on the supply chain in the field of maritime transportation and have developed the framework and presented it as a proper conceptual model in accordance with the structure of model-making in the articles (inclusive of initial hypotheses, variables, parameters, etc.
The remainder of this paper is organized as follows: In section two the maritime inventory routing problem is presented in its general form; in section three the conceptual model for the questions is elaborated based on the framework of the maritime supply chain; in section four the aftermath of achieving the objective and the ways for solving the problem are dealt with, and in section five the grounds for the development of the model are described based on the conducted studies and the proposals made by the authors of this article.
Production Rate: The production rate is considered as an exogenous variable in most studies, but in articles in which the approach is based on a combination of discussions on production planning, routing and inventory management the production rate is regarded as a self-generating or endogenous variable in the model-making process.
