In order to cope with re-configurability of manufacturing system, it is quintessential to test industrial control logic rapidly and easily in the design-time, and monitor operational behavior correctly in the run-time of automated manufacturing system. Proposed integrated model for virtual prototyping and operational monitoring of industrial control logic is to improve limitations of current la...

Abstract—A steam power plant is housed with various types of equipments like boiler, turbine, heat exchanger etc. These equipments are mainly connected with piping systems. Such a piping layout design depends mainly on stress analysis and flexibility. It will vary with respect to pipe geometrical properties, pressure, temperature, and supports. The present paper is to analyze the presence and e...

In this paper the layout of pilot plant (100 kg/h) for the supercritical water gasification (SCWG) of biomass is proposed. The proposed layout involves a reactor, units to separate water and hydrogen, a burner and several heat exchangers. This scheme was also simulated by means of the commercial software Aspen Plus (Aspen Tech, Inc.) in order to state the influence of different parameters such ...

In this paper, we address the problem of designing flexible plant layouts for manufacturing facilities where product demands are subject to variability. A flexible layout is one that maintains low material handling costs despite fluctuations in the product demand levels. We extend existing procedures for design of flexible layouts by (1) explicitly capturing the stochastic nature of product dem...

In this study, we have classified different types of problems which are related to facility planning and layout design for different types of manufacturing processes. The main problems which are related to location of facilities which also affects the system performance such as distribution of man, material and machine in a plant or a factory and their optimization technique while using of math...

Blocking and shadowing is one of the key effects in designing and evaluating a thermal central receiver solar tower plant. Therefore it is convenient to develop efficient algorithms to compute this effect. In this paper we explore the possibility of using very efficient clipping algorithms developed for the video game and imaging industry to compute the block and shadowing efficiency of a solar...

This paper presents an application of 5S lean technology to a production facility. Due to increased demand, high product variety, and a push production system, the plant has suffered from excessive wastes, unorganized workstations, and unhealthy work environment. This has translated into increased production cost, frequent delays, and low workers morale. Under such conditions, it has become dif...

Logistics, transportation and distribution engineering can be divided into internal or in-plant logistics and external manufacturing or distribution logistics. The Internal or in-plant logistics includes the material handling systems and storage systems and the external manufacturing or distribution logistics includes the transportation modes such as trains and trucks. Both must be integrated i...

In this paper, an optimisation-based approach to obtain safe multi-floor process plant layout designs using the domino hazard index (a sub-index of integrated inherent safety index) is presented. A mixed integer linear programming (MILP) model proposed economically optimal design considering connection by pipes, horizontal and vertical pumping fluids, purchase land, fixed area-dependent constru...

In this paper, the facilities design of a manufacturing layout is conducted by integrating simulation and design of experiments to study the influence of process parameters on the performance of the plant. This research study involves a shop floor wherein the parts contributing to 75% – 80% of the annual revenue are analyzed. This is achieved by selecting a few potential parameters/factors that...
