Pipelines provide an economic fluid transportation mode for petroleum systems, especially when large amounts of petroleum derivatives have to be pumped for long distances. The system reported in this paper is composed by an oil refinery, one multiproduct pipeline connected to several depots and to the local consumer markets that receive large amounts of oil products. Extensive distances must be...

The finite element modeling (FEM) technique has been applied to study the loading-unloading characteristics, stress and strain fields of the bulk materials such as titanium, iron, copper and thin films of titanium and copper subjected to Berkovich nanoindentation process. The loading and unloading curves obtained from numerical simulation results are compared with the curves obtained earlier th...

A battery charging station (BCS) is a charging facility that supplies electric energy for recharging electric vehicles’ depleted batteries (DBs). A BCS has a certain number of charging bays and maintains a dynamic inventory of fullycharged batteries (FBs). This paper studies a BCS scheduling (BCSS) problem whose target is to schedule the charging processes of the charging bays such that the cha...

In this study, we consider a flexible manufacturing cell (FMC) processing identical parts on which the loading and unloading of machines are made by a robot. The machines used in FMCs are predominantly CNC machines and these machines are flexible enough for performing several operations provided that the required tools are stored in their tool magazines. Traditional research in this area consid...

Aircraft maintenance planning and scheduling constitute planning, control and execution of materials (spare parts), operations (inspection, disassembly and assembly activities) and resources (labour, machines, transport equipment, etc.). This is a complex problem due to large number of components involved at various planning and execution levels, and the size/nature of resource-intensive mainte...

this paper introduces the general framework of a new system for material flow planning and operations and some of its important aspects. the justification for the new system stems from the short coming of mrp  i/mrp ii in term of its assumptions, particularly in relation to fixed lead times and effectively infinite production capacity. at the heart of the system is an automatic scheduler based ...

The nautical safety of bulk carriers is largely determined by their correct loading. available ship's instruments do not allow timely planning loading operations and real-time control the condition during execution. officers in charge have to spend a lot time preparing (unloading) plans. high intensity cargo at modern dry terminals lack sufficient prepare verify new plan may create risk holds b...

Through the needs of Loading-Machine storage scheduling in forestry-pulp-paper production logistics intelligent distribution system, analysis the Loading-Machine scheduling model of problems and improvement measures, put forward Loading-Machine intelligent production scheduling algorithm, based on ensuring the feasibility of scheduling, scheduling to rationalization, equalization, execute only,...
