In this paper we describe an algorithm that allows to compute a path connecting two elements in a pipe network with valves, minimizing interferences with other envisaged connections. First we present a method to model a pipe network as a directed graph with edge capacities (flow network) allowing maximum flow analysis and incorporating specific constraints relative to a seaport oil transport system...
This paper describes the methodology and solution to automate and monitor a sewage treatment plant from an industry dedicated to the manufacture of wood panels. The control system designed, not only governs all elements of performance of the plant, but also oversees its proper functioning. It also has a human-machine interface with a daily working and emergency program, accompanied by an information...
The Small to Medium Enterprises (SMEs) precise more and more suitable systems to be automated. In this work is examined the possibility of programming a filling system, mixed and packaged of liquids automatic. PLC's are used for control. It is tried to make an integral automation taking into account the questions of rapidity and safety. A study is made on different possibilities in the packaging from...
Industry is necessary more and more suitable ways of get in automatic process. In this work is presented an algorithm of programming of process control for elaborating and packing industrial of a liquid product by a Programmable Logic Control (PLC). Not only an integral process control is desired, but also the finest way is targeted in the sense that less time of the process is founded. A study comparative...
