The Past

Over the past few years, the interest towards off-site construction as part of project delivery for residential and commercial buildings has increased dramatically. In this regard, buildings are decomposed into panels that are manufactured using assembly lines smilar to what was developped to the automotive industry. However, because these serial production systems do not have buffers that could store intermediate products when a bottleneck occurs downstream, it often happens that these products are required to wait at the current workstation before production can resume. In this contribution, we develop algorithms allowing the waiting times to be extracted from timestamps that are collected from an RFID system reading the tags on panels as they enter each workstation.

Positional Weight

In this modern era, the competition among the manufacturing industry, especially in the automotive sector will become increasingly tight which causes companies need to innovate so that satisfaction of the consumer can be maintained. The production process will be an important aspect in the automotive industry to maintain the quality of products and ensure consumer demand can be fulfilled. The problems that often occur in the production process is in the form of production flow constraints caused by workload unbalanced in the assembly lines. The imbalance causes the assembly lines do not run in a cycle time that is determined, so that consumer demand can not be meet in the right amount and companies need to spend more to mitigate them. Therefore, this study was conducted to balance workload on the assembly line by using line balancing form Ranked Positional Weight (RPW) with a subsequent increase in the efficiency and productivity of assembly line that affect production process runs without any contraints.

Alignment Strategy

The proper alignment of facets on a dish engine concentrated solar power system is critical to the performance of the system. These systems are generally highly concentrating to produce high temperatures for maximum thermal efficiency so there is little tolerance for poor optical alignment. Improper alignment can lead to poor performance and shortened life through excessively high flux on the receiver surfaces, imbalanced power on multicylinder engines, and intercept losses at the aperture. Alignment approaches used in the past are time consuming field operations, typically taking 4–6 h per dish with 40–80 facets on the dish. Production systems of faceted dishes will need rapid, accurate alignment implemented in a fraction of an hour. In this paper, we present an extension to our Sandia Optical Fringe Analysis Slope Technique mirror characterization system that will automatically acquire data, implement an alignment strategy, and provide real-time mirror angle corrections to actuators or labor beneath the dish. The Alignment Implementation for Manufacturing using Fringe Analysis Slope Technique (AIMFAST) has been implemented and tested at the prototype level. In this paper we present the approach used in AIMFAST to rapidly characterize the dish system and provide near-real-time adjustment updates for each facet. The implemented approach can provide adjustment updates every 5 s, suitable for manual or automated adjustment of facets on a dish assembly line.

The present paper is a continuation of a larger study of the authors, which consists of an analysis on the performances of several production systems. In this paper it is analyzed the influences of the method of managing the flows, the method of production programing and the clients demand on performance indicators of a multiproduct assembly line supplied on stock. The assembly line is designed to produce two types of similar products and is made of 5 workstations with mainly manual activities, which are supplied with parts on a stock based method. The performance indicators chosen for analysis were: average work in process, cost per unit, systems reactivity to client demand and throughput. The values of these indicators were obtained by simulating the assembly lines functioning in different experimental conditions, determined of the variation of above mentioned variables, by using ARENA software. The obtained results were interpreted and structured, in a manner to help the process managers to take adequate decisions considering the wanted objectives.

AbstractThe paper addresses application of digitazation of production processes, which is part of organizational digitization, also known as Industry 4.0. It deals with modernization and optimization of production systems by creating models in simulation software via digital engineering. For our analysis, 8 real assembly lines were used, with an average of 15 workplaces, which were integrated into one universal line by means of simulation. The aim of our research was to create a digital twin of the real assambly lien and to analyse effectiveness of the proposed modernization universal assembly line using the generated statistical data.

The present paper is part of a broader study of the authors, consisting of modeling and simulating several production systems. Functional modeling of a workstation supplied by various methods was carried out and presented in the paper [. This paper presents the functional modeling of an assembly line composed of 4 workstations with manual activities, designed to make 4 types of products (multi-product line). The supply with parts of the line is made with kitting system. The novelty of this study is the use of IDEF0 functional modeling method to describe the functioning of the assembly line in which the supply method is synchronous. The functional model developed had allowed to identify and to design the kitting and picking circuits, as for the highlighting of the traces followed by the components to the workstations, depending on their type of supply. This model can be extended and used to other assembly lines supplied in synchronous.

Abstract This article deals with issues related to the flow of material to the assembly line and examines the possibilities of reducing the costs of this process. It is based on the current state of the transport of individual parts to the producing company and the storage system using Kanban and Just in Sequence (JIS) logistics technologies, and the subsequent collection of material for transport to the assembly line. The change in the system of transport technology has led to a reduction of the total storage space and costs, and at the same time, the processes related to storage and collection of parts have been simplified. The whole process of material flow to the assembly line is solved using the real supply system via the JIS technology, together with the system of receipt and storage of components in connection with individual operations during the handling and storage of these components, and their picking and transport to the assembly line. Evidently, the change in the system and the associated savings can also be employed to warehouses and manufacturing companies of the automotive industry, which use automated assembly lines with the timing of the assembly process of the final product.

Over the past few decades, conventional agriculture has been facing serious crises caused by numerous factors, including poor soil management and the excessive application of pesticides. Thus, alternative production systems have been developed, including agroforestry systems, especially those that produce both energy and food. The objective of this study was to environmentally evaluate the culture of Aleurites fordii Hemls. (Tung) using the Life Cycle Assessment method with the SimaPro 7.3.2 software. The results revealed that in family farms that use less mechanization to harvest crops, the primary category of environmental impact was land use, which included the removal of animal and vegetable species and ecosystem changes. The full impact of this category was 1741.21 m2yr PDF (potentially disappeared fraction). Subsequently, prognostics were established for the reduction of such impacts, and we conclude that Tung has a high potential for agricultural installation with high responsibility to the environment.
