One of the major obstacles in the process of national development, is the disruption in regional balance construct. As has been noted in some studies the existence of regional inequity leads to domination of some regions to surrounding regions and causing political and economic challenges in developing countries. And given that transportation is one of the components of region, undoubtedly equi...

Scheduling is an important subject of production and operations management area. In flow-shop scheduling, the objective is to obtain a sequence of jobs which when processed in a fixed order of machines, will optimize some well defined criteria. The concept of transportation time is very important in scheduling. Transportation can be done by robots. In situations that robots are used to transpor...

The present work analyses a particular scenario of consensus formation, where the individuals navigate across an underlying network defining the topology of the walks. The consensus, associated to a given opinion coded as a simple messages, is generated by interactions during the agent's walk and manifest itself in the collapse of the various opinions into a single one. We analyze how the topol...

The paper presents a yield optimizing scheduling system (YOSS) in a decentralized supply chain management (DSCM) environment. For this purpose we employ a DSCM scenario in which each supplier, provides system parts by order of one or more customers. The supplier tries to optimize its return by searching the optimal schedule for the single machine he uses to manufacture the requested products. T...

Human mobility has been empirically observed to exhibit Lévy flight characteristics and behaviour with power-law distributed jump size. The fundamental mechanisms behind this behaviour has not yet been fully explained. In this paper, we propose to explain the Lévy walk behaviour observed in human mobility patterns by decomposing them into different classes according to the different transportat...

A systematic procedure including process design and integration techniques for designing and operating energy distribution networks, and for transportation of resources is presented in this paper. In the developed model a simultaneous multi-objectives and multi-period optimization is principally investigated. In addition to optimize the transportation of resources/products, the proposed method ...
