Introduction

Due to a poor layout, production costs and time are wasted, making the business unprofitable and causing customer dissatisfaction. Because the layout wasn't right, the workers needed a lot of energy and time to make the less production that was already there. In this manner, the review was directed to further develop productivities of the organization by decreasing tedious interaction and variables influencing creation pace of the organization utilizing information from DBL( Bangladesh possessed creation) fabricating plc to deliver legitimate spread out. The researcher compared the efficiency, production, and cycle time of the existing and new layouts. Thus, the improved lay out efficiency of 24.14 percent, production 1546, and cycle time correspond to the existing efficiency of 21.82 percent, production 1387 per day sample 3 blocks, and cycle times, respectively. A product that is too big or heavy to move is best displayed in a fixed-position layout. Battleships, for instance, are not made on an assembly line. The fixed position for services may be determined by other factors (such as in an operating room in a hospital where the patient is brought medical personnel and equipment). Construction (such as buildings, dams, and electric or nuclear power plants), shipbuilding, aircraft, aerospace, farming, oil drilling, home repair, and automated car washes are additional examples of fixed-position layouts. The necessary resources must be portable so that they can be brought to the job for "on the spot" performance in order for this to work [1-3].

Literature Review

The goal of assembly line balancing and assigning jobs to machines is to minimize operator workflow, shorten throughput times and reduce work in progress, and thus increase productivity. Division of labor is when multiple individuals share a job. Equal division of labor should be achieved by ensuring that each station is used for roughly the same amount of time. Each step in the product's assembly must be carefully evaluated before being distributed among stations in proportion to the available workstations. The work flow, synchronized line, includes short distances between stations, low volume of work in process, precise planning of production times, and predictable production quantity. Each operator then carried out operations correctly.

An assembly line is defined as a set of distinct tasks which is assigned to a set of workstations linked together by a transport mechanism under detailed assembling sequences specifying how the assembling process flows from one station to another. Since sewing process is labor intensive; apart from material costs, the cost structure of the sewing process is also important. Therefore, this process is of critical importance and needs to be planned more carefully. When sewing both a section of the garment and the entire thing, layout is very important. Space utilization is improved, production costs are reduced, and production time is shortened with an efficient layout. However, DBL Industries Ethiopia is losing money due to a layout issue with its sewing production lines. The sewing production lines are not set up in a way that makes it easy for material to flow through the line. As a result, the primary objective of this project is to solve the issues that prevent the line from achieving remarkable success.

The basic steps of sewing involve using a needle and thread to attach fabrics, leather, furs, or other flexible materials. Sewing is mostly used to make clothes and things for the house. In fact, sewing is one of the most important steps in making clothes. Industrial sewing machines are used for the majority of this kind of sewing. At the beginning, cut pieces of a garment are typically tacked or temporarily stitched. The intricate components of the machine then interlock the thread by piercing it through the layers of the cloth. In the apparel industry, this study on apparel analysis for layout planning is very important. Practically speaking we are utilizing more machines, labor supply, unrefined components, and different assets because of the absence of appropriate sewing line design as well as the earlier exact piece of clothing investigation. The sewing line should be aligned in accordance with the garment's style. As a result, it would use fewer resources—humans, machines, materials, money, etc.—and reduce all forms of waste. We have learned about the various layout plans for various styles in this study, as well as a comparison of the actual layout [4].

Industrial sewing machines for kind of sewing

Although combined treatment may be an excellent method for overcoming antiangiogenic drug obstruction and increasing its antitumor movement, it may result in increased poison levels and cost. Enhancing the viability of antiangiogenic specialists and improving the endurance of ovarian disease patients are two areas where the clever reasoning blends have a great chance of success. Immunotherapy is one of the most encouraging and promising areas of clinical disclosure in aggressive cancers. It has revolutionized the treatment of malignant growth by enabling strong control of previously severe and profoundly destructive diseases. Through reactivating damaged or depleted T cells, invulnerable designated spot inhibitors (ICIs) demonstrate remarkable efficacy against various diseases. The majority of patients with growths did not benefit from invulnerable designated spot inhibitors and experienced severe adverse events. The whimsical example of clinical reaction to ICIs' precise system has not been explained. A lot of research has been done on biomarkers that predict ICI response in order to improve immunotherapy accuracy in the future [5].

Discussion

Permanent magnet synchronous motor (PMSM) servo drive system has been widely used for industrial sewing machines. The conventional control method is PID, which has some disadvantages such as large overshoot, bad robustness. In this paper, a servo control of the industrial sewing machine system based on the active disturbance rejection control (ADRC) is proposed, which can arrange the transient process, estimate and compensate the uncertain internal and external disturbance. It can highly enhance the dynamic performances of the system. Based on the Matlab/simulink software, the simulation results of the industrial sewing machine control system proved the effectiveness and robustness of the ADRC control strategy.

Conclusion

The purpose of this paper is to develop and test control methods for realtime automatic presser-foot force control in industrial sewing machines. In this work, a closed‐loop controller that controls presser‐foot maximum vertical displacement is presented and compared to existing solutions that adjust force depending on sewing speed. Automatic force control can reduce problems such as stitch irregularity, stitch distortions and material damage, besides making material handling easier.
