One of the problems of existing irrigation networks is seepage phenomena. Seepage problem and its control in irrigation channels is one of the most important issues in the design, construction, maintenance and operation of these channels. In this study, simulated the rate of seepage and phreatic lines in the Mianab irrigation and drainage channels located in the Karun basin using mathematical t...

Availability and reliability of a manufacturing system are the most common indicators in the reliability engineering area to assess the quality and on-time deliveries of the products they produce. The purpose of this paper is to analyze the availability, reliability. failure metrics such as MTBF and MTTF, and also steady-state availability of a cooking oilproduction line using a Markov approach...

Many production line imbalances have been observed in the pursuit of higher profits. A sustainable production line, also called balanced, leads to lower costs, good production environments, and green manufacturing. A decision analysis method, such as production line evaluation, is often employed to help decision makers make sustainable decisions. In this study, a sustainable decision-making mod...

The continuous development of information technology has increased the level automation and informatization in manufacturing industry, which makes it necessary for companies to effectively monitor their assembly lines. Aiming visualize monitoring challenges line production process, taking industrial detonator automatic as research object referring digital twin five-dimensional model, a visualiz...

Batik Delapan Satu is a manufacturing company specializing in the garment field. There bottleneck line at production that can cause to be hampered. This occurs trimming workstation, so imbalanced work flow. Then, we use Line balancing with Ranked Positional Weight method and Region Approach solve this problem. Using will produce efficiency, balance delay, idle time, smoothness index. increase e...

Plastic injection is a method in which, with using an extruder in granules, plastic is injected in a hole with high pressure. Because of meeting the two flow fronts in this process welding line will be made. Along the welding line the strength of produced part is low; therefore the position of welding line and its clarity are very important. In this paper, analyzes have been done with Fluent an...

In this paper an aggregate model for manufacturing systems consisting of flow lines with finite buffers and parallel servers is proposed. The proposed model is a multi-server station with process times depending on the work in process (WIP). An algorithm is developed to measure the WIP-dependent process times directly from industrial data such as arrival times at and departure times from the ma...

In this document some efficiency measures of the operation of a serial line manufacturing are discussed from a stochastic approach. In this work we use the concept of operations decoupling in manufacturing systems to place buffers between each operation in order to reduce sequential interdependence between downstream and upstream operations. This will also maintain the output of the production ...

The integration of manufacturing design knowledge with live production data in composite services improves the ability for manufacturing lines to reconfigure and recover from errors. By using manufacturing design knowledge captured as ontologies planning level faults on assembly lines and conflicts in between product design and line can be automatically identified. In addition by using embedded...
