Imam Bonjol No. 18 Bugul Lor, Pasuruan City, East Java. The industrial machinery and equipment division and foundry unit (MPI) located in Pasuruan has grown rapidly as a company that focuses on manufacturing machinery and produces products such as Oil & Gas/ Refinery / Petrochemical Industries, Power plans, Iron Casting, and Pressure Vessels. In PT. Boma Bisma Indra, whose orientation is a make-to-order company, where the new company will procure raw materials and run production if there is a request from the customer. Difficulties that are often encountered in make-to-order companies are delays in the arrival of raw materials, and process delays caused by inadequate workers. Therefore, a method called the Master Production Schedule (MPS) is needed where this method will determine the time period that will be required for each process starting from the preparation of documents related to procedures and product specifications to the finishing fabrication process. This research focuses on timeliness analysis in every process in the master production schedule using the master production schedule (MPS) method.

AbstractEmployers are under a legal obligation to provide employees with safe and hygienic conditions of work. These conditions are created by environmental factors that depend on the specifics of the enterprise, production technology and used machinery and equipment. A large number of the risks to which employees are exposed is associated with the use of machinery, equipment and working tools (as confirmed by Statistics Poland). Numerous manufacturing companies increasingly use the practice of involving operators, independently from the maintenance department, in the upkeep and maintenance of machinery and equipment in order to increase efficiency. These activities are undertaken within the scope of Autonomous Maintenance (AM), which is one of the essential elements underpinning the TPM system. The activities performed by operators within AM, such as daily inspections, lubrication or simple repairs, reduce the number of machinery breakdowns. Nonetheless, they could be a potential source of risk for employees. Companies applying the traditional division of tasks entrust the performance of such activities to qualified maintenance staff, so the proper identification of risks that takes into account the specificity of the activities performed by operators and the provision of training in the safe organization of work represent a significant feature of safety improvement. Enterprises may adopt multiple solutions in this regard, including the tools and techniques of the concept of Lean Manufacturing.

The behaviour of firms is still a little understood matter. Why one firm or industry is investing more than the other or what makes a firm enter or exit from the market, what are the psychological factors that go to make a choice of this kind are questions that have not been answered satisfactorily. Concepts like irreversibility, uncertainty, investment, and the value of waiting are very much there in the literature, e.g., McDonald and Siegel (1985, 1986); Nickell (1974); Schmalensee (1972); Hartman (1972); Henry (1974) and LAM (1989) and others. But the psychology of decision-making on the face of losses has not received much attention in the literature. That the Economic Hysteresis1 and Layers of Techniques2, developed by Professor A. Dixit and Professor P. N. Mathur respectively tackle. The former is discussed by Pindyck (1988, 1991, 1992) and Dixit (1989, 1989a, 1991, 1992); while Mathur (1977, 1989, 1990); Law and Azid (1993); Azid and Ghosh (1998) and Rashid (1989,1989a) have discussed the latter.

Purpose: This paper analyzes how the manufacturing supply chain has changed over the past 20 years according to the trilateral division of labor between Korea, China and Japan. Also, by measuring changes in the trade structure and competitiveness between Korea, China and Japan during the same period, the effect on the changes in the supply chain between the three countries is examined.
Research design, data, and methodology: This study analyzes the trade structure, export competitiveness, and supply and distribution structure of 10 manufacturing industries in Korea, China and Japan. The analysis period was set from 2000 to 2020. The statistics use the UN Comtrade and the Asian International Input-Output Table. In the analysis of the trade structure between Korea, China and Japan. The Revealed Symmetric Comparative Advantage (RSCA) index was introduced to analyze the trade structure between Korea, China and Japan. And for the supply chain structure between the three countries, the Leontief inverse multiplier decomposition of the International Input-Output Analysis was used.
Results: As a result of the analysis, it was observed that the supply chain of the manufacturing industry between Korea, China and Japan has changed to an interdependent structure since 2010, and the reason for this is that the production technology gap between the three countries has been greatly reduced. Accordingly, the supply chain of the manufacturing industry between the three countries has shifted from the past one-way dependence structure to a two-way dependence structure. In terms of industry, the deepening dependence among the three countries centered on electrical/electromechanical machinery, metal products, general machinery, chemical products, transportation machinery, precision machinery and textile products, which are key export industries for both Korea, China and Japan, means that the supply and distribution structure is being strengthened.
Implications: Considering the relationship between the supply chain between Korea, China and Japan from 2000 to 2020, institutional integration, such as the trilateral FTA, is delayed, but functional integration is deepening due to interdependence and complementarity and increased production and trade. However, if trade frictions or disputes between Korea, China and Japan occur between specific countries, it is interpreted that this can lead to negative effects, so-called big losses, not only for the country concerned but also for the other country.

The interest in scientific research within the metal finishing sector is growing. The demand for durable metals and adaptable manufacturing processes is increasing across a wide range of applications, from aerospace and automotive to machinery and jewelry. In that respect, alloy plating offers better answers in terms of economic growth and environmental sustainability due to fine-tuning composition, morphology, and crystallinity [1]. Here, current trends in alloy electrodeposition research are reviewed highlighting open challenges and process innovations from an industrial perspective. Combining basic electrochemical techniques with spectroscopic, microscopic, and structural techniques is crucial for characterizing the structure-activity relationship for many different technological devices. Particular attention is devoted to advances in industrial quality control and viable solutions for the reduction of precious metal content in electroplated accessories as well as the replacement of cyanide and nickel baths with non-toxic compounds.

In recent years, China’s manufacturing industry has developed rapidly, but numerous studies have shown that China is not a manufacturing powerhouse. In recent years, the division of labor in global value chains has been booming, and the Chinese manufacturing industry has been actively integrated into it with its labor cost advantage and achieved rapid development. There is an urgent need to transform and upgrade to high value-added links in the value chain. This paper measures the upstream degree of China’s manufacturing industry through the world input-output table and uses it as an indicator to measure the global value chain status, focusing on the heterogeneous impact of different types of productive services on the upgrading of China’s manufacturing industry’s global value chain status. This study examines the impact of global value chain boundary lessness and institutional quality on the technological complexity of China’s equipment manufacturing exports, using panel data of six types of Chinese equipment manufacturing industries from 2007 to 2018 as a sample. The findings show that intermediate manufactured goods from intermediate imports and intermediate products from developing economies make the strongest contribution to imported intermediate manufactured goods from developing economies. By industry, the impact areas of Graph Visualization (GV) embedding and institutional quality are different. GV embedding has a stronger contribution to the manufacturing of communication, computer, and other electronic equipment, while institutional quality has a stronger contribution to the manufacturing of special office machinery, and the interaction between the two is the same as that of institutional quality.

Abstract Between 1825 and 1850, New York became the most productive manufacturing city in the United States-the metropolitan center of a manufacturing complex that reached as far south as Delaware and that by the late 1840s was probably the fastest-growing large industrial area in the world.1 These extraordinary developments utterly changed the city’s crafts, but in ways very different from those evoked by the usual images of early industrial growth. Huge firms absorbed thousands of craft workers-but did not eradicate the city’s small producers. New, highly sophisticated steam-powered machines thundered in the factory districts-but most of New York’s largest manufacturers intensified the division of labor already underway rather than invest in labor-saving machinery. Although a few, rapidly growing trades dominated the city’s manufacturing economy, hundreds more remained, leaving New York with a manufacturing sector of almost baffiing diversity. Then, as now, Americans looked elsewhere to interpret the coming industrial era. Nevertheless, at midcentury the most productive manufacturing center in the nation was neither a mechanized contrivance like Lowell nor a single-trade boomtown like Lynn, but a metropolitan labyrinth of factories and tiny artisan establishments, central workrooms and outworkers’ cellars, luxury firms and sweatwork strapping shops.

Since the late 1980s a growing number of geographers and other social scientists have chronicled the apparent rise of post-Fordist economic systems (Scott and Storper 1987; Schoenberger 1988; Harvey 1989; Storper and Walker 1989; Boyer 1990; Storper 1997). These systems are said to employ a flexible approach to production reflected in employment relations, the organization of work within firms, and the broader social division of labour (Cooke and Morgan 1998). To some, the heart of this transformation lies in the rise of a new set offerees of production (Walker 1994). In particular, they point to a new set of flexible process technologies whose programmable properties offer producers prospects of great versatility, limited downtime, unparalleled precision, and superior quality. The same technologies are said to hold the potential to unleash the creative potential of workers, and to compel manufacturers to establish a new regime of co-operation on the shopfloor (Florida 1991). Despite the popularity of such arguments, their unqualified acceptance has not been universal. A critical literature has arisen which, among other things, questions the pervasiveness of such practices, especially in locations outside the paradigmatic flexible production regions (Gertler 1988; 1992; Sayer 1989; Pudup 1992). The evidence reviewed in Ch. 2 attests that, while rates of adoption of flexible technologies such as computerized numerical control (CNC) are reasonably high amongst manufacturers in countries such as the United States, Great Britain, and Canada, many firms in these countries have experienced considerable difficulty in trying to implement such technologies effectively (Jaikumar 1986; Beatty 1987; Meurer, Sobel, and Wolfe 1987; Kelley and Brooks 1988; Turnbull 1989; Oakey and O’Farrell 1992). Furthermore, the discussion in Ch. 2 also shows that there is an apparent regularity to the geography of technology adoption difficulty that is highly suggestive of its roots. Many of these implementation difficulties seem to arise in older, mature industrial regions, where manufacturing firms are far removed from the major production sites of the new flexible production technologies. Increasingly, the leading producers of these process technologies are to be found in such countries as Germany, Japan, and Italy, while once-dominant American machinery producers have seen their market shares drop significantly, both at home and abroad (Graham 1993).

With Samuel Slater’s textile mill (1793, in Pawtucket, Rhode Island) and Eli Whitney’s armory (1798, in Whitneyville, Connecticut), American entrepreneurs began to make in factories products that had formerly been made in homes or craft shops. Another new concept in manufacturing, the principle of uniformity (sometimes described as “interchangeability”), was also winning converts in America. Factories making uniform products increasingly used power-driven machinery in the production process. However, it is a mistake to conflate mechanization, factories, and uniformity. Mechanization was used in colonial craft shops as well as in nineteenth-century factories. Until the late nineteenth century, factory managers achieved uniformity primarily through improved handwork skills and gauging rather than with machinery. Chapter 9 will cover the mechanization of work in factories as well as efforts to achieve uniformity in machine parts. Many of the best examples of early American factories are in New England, where there was a serendipitous combination of water power, entrepreneurial capital, and the artisanal skills necessary to build mills and machinery. The textile mills erected there had a powerful influence on the evolution of American factory architecture. As we look closely at a number of New England mills, remember that similar patterns of structural development can be found in other regions of the United States and that the basic forms of the textile factory were readily adapted for other types of industry, including the manufacture of wood, metal, and paper products. Factories were not the first industrial buildings in America, nor did they represent more capital expenditure than some of the early and costly ironworks. Two processes of textile manufacturing and finishing, the carding of fibers and the fulling of woven cloth, had been powered by waterwheels (and occasionally by draft animals) before the first successful factory was built in Pawtucket in 1793. Proprietors of shops and country mills usually operated their enterprises directly with little of the managerial hierarchy and division of labor that would appear in the full-blown factory system. Shops lacked the factory’s sequential organization of powered machinery and its extensive mechanization through multiple stages of production.

Abstract The study of product development at Hewlett-Packard is extremely compelling, because in the last five years the huge corporation has made a radical shift in the way it pursues development projects. For decades the company was organized into highly structured and completely autonomous divisions. Project development was always contained within a division. The methods by which one division pursued projects, however, were often completely different from those used by another, although one relationship was always common to them: design engineers ran the show, and marketing, manufacturing, and other groups in each divisions were left to adapt to whatever the engineers settled on.

The increasing skill mismatch in manufacturing workforce is raising demand for training opportunities to cope with advanced manufacturing systems. To maintain production and adjust quickly to technological transformation, innovative work-based learning approaches are emphasized. Intelligent machines are becoming capable of interaction and collaboration with humans. They not only introduce a new type of learnable workforce to manufacturing but may open opportunities to enhance learning of all learners. Symbiotic relationships of humans and machines have wide potential for human-centric manufacturing (aka Industry 5.0). Moreover, connecting smart devices and deploying self-learning solutions is envisioned to increase flexibility of manufacturing, thus changing work division between humans and machines. Where humans and machines collaborate, the term Reciprocal Learning has been coined to describe the process of bidirectional learning. While a definition of Reciprocal Learning exists the boundary conditions of the concept are still ambiguous. In this paper, a framework for Reciprocal Learning in Human-Machine Collaboration for Industry 5.0 is presented to clarify what it is and what it isn’t. The approach is based on a multi-agent system perspective, comprising human and machine agents. Finally, an outlook on future research is presented.

The results of integrating OT and IT in Manufacturing Industries are Increase in Productivity, Reduction in Waste, Savings in Labor and Energy and Better Maintenance. The convergence of IT and OT in IoT has been going on for a while and there isn’t a strict division between them in the real world. Traditionally, IT is responsible for creating, storing and securing an organization’s data. At the same time, OT focuses primarily on processes that take place in the physical world-think managing productivity, people, and machinery. There are Pre Design Phases and Final Design Phases for Implementation of the Integration process. Under the Pre Design Phases, Identify the types of Assets in Industrial Zone and those that support Production and then Identify “Who” owns the hardware and software in the asset. In the final Phases of implementation we have: Requirements Phase: Interview all the system owners to gather requirements for operations, configuration and maintenance. Architectural Phase: Produce High level documentation and drawings to meet every requirement. Technical Design Phase: Produce detailed documentation such as drawings, switch configuration and VLAN, IP Address and Firewall ACLs. Implementation Phase: VERIFY “was the product built right?” and VALIDATE “was the right product built?” process. Maintain Phase: Modify configurations and assets to fix anomalies or required operational changes. The Intelligent Automation is Transforming Manufacturing Processes. The explosive growth of the cloud has made on – demand processing more accessible, more efficient and relatively lower cost. Robotic Process Automation (RPA) tools use Cognitive capabilities will replace those that don’t. There are several obvious benefits of automation that can be found in various automation projects as primary positive results. Among others, they include: #Cost Reduction #Higher Accuracy #Increased focus on core competencies #Improved productivity #Better compliance #Creating New jobs #Reducing Employee turnover. Three types of automation in production can be distinguished: 1. Fixed automation, 2. Programmable automation, and 3. Flexible automation. In many industries IT and OT convergence already happens since quite some time (Oil and Gas is just one of the many). Utilities are realizing that to reap the full benefits of advanced metering and smart grid systems, IT and OT must work together.

The virtual reality is a multi-functional, interactive and immersible technology. As an advanced engineering design technology, the virtual reality technology (VRT) has been widely used in large mining machinery design and manufacturing. The system is based on DIVISION Mockup2000i2 software. Virtual prototype of the Tunnel Boring Machine (TBM) is studied in this paper. In addition, the movement simulation of TBM is completed in DIVISION Mockup2000i2. Firstly, CATIA software is adopted to build the parts of TBM. The TBM is assembled in CATIA too. Secondly, the THEOREM software is applied to convert the assembled model of TBM to another format which can be identified in DIVISION MOCKUP2000i2 software. In order to make the TBM image living, life-like and easy to browse, the light of surface, virtual materials and landmark scenes are set up in DIVISION MOCKUP2000i2 software environment. All motion parameters of the parts are defined before the simulation. Then, the virtual movement simulation of TBM components is analyzed with the behaviors property of MOCKUP. The virtual movement of cutting wheel, screw conveyor machinery and the door of mud out are studied. The virtual movement of segments and segment erector machine are completed by setting up virtual parts and virtual event. Five segments are fixed accurately in a cycle. The relations and interference of the parts movement are examined simultaneity. The hotkey is defined before the simulation, which can trigger the continuous implementation of virtual motion. In addition, a virtual voice is used to enhance the performance of movement simulation. The virtual prototype of TBM being set up and simulated will have positive significance for design inspection, structural analysis and product introduction without TBM physical prototype being manufactured.

Abstract Despite the growing application of additive manufacturing (AM) in fabricating complex designs, most machines suffer from small working envelopes and slow processing speeds. One workaround to the problem of small throughput in AM is to partition the volume of a desired object and fabricate sub-volumes in parallel. Prior related work has focused on two problems. One is the geometric division problem, disregarding AM benefits and challenges in determining partitions. Others attempt to install multiple AM processing heads on the same machine, ensuring seamless bonding between deposited material from different heads while avoiding interference among them. A missed opportunity lies in deploying many independent machines simultaneously while considering benefits and limitations of AM. To that end, objects too large to be fabricated on one machine, are divided primarily into cubes that exploit benefits of AM. Specifically, the cubes are hollowed out in the direction of printing to reduce weight while avoiding the need for support structure, and depending on load conditions, packed in different orientations to mitigate material anisotropy.

Abstract There is an increasing interest in using additive manufacturing for structural materials, including pressure-retaining components. This requires that the manufacturing methods be included in Codes and Standards, such as the Boiler Pressure Vessel Code. This work is already moving forward with the development of a Section III Division 1 Code Case to include 316 stainless steel that is manufactured using powder bed fusion, an additive manufacturing technique. However, Code Cases will become significantly more challenging when time-dependent properties must be considered, such as in Section III, Division 5. Section III, Division 5 requires design models based on creep as well as creep-fatigue interaction. Testing for this is time intensive and costly. Additive manufacturing properties are a result of feedstock material as well as processing methods/parameters. The individual machines take what used to be centralized material fabrication (into large plates of castings) and spread the process out to many separate facilities. This decentralized fabrication, paired with the rapidly changing landscape of additive techniques and equipment manufacturers, has created difficulty in quality control and producing code cases. For low-temperature code cases, this has been circumvented by requiring witness specimens that meet specified property requirements. Additional witness specimens to cover time-dependent properties would significantly increase the cost and delay processes, so similar methods may not be effective for high temperature applications. This paper covers fabrication and modeling/simulation challenges associated with qualification of additive manufacturing processes for high-temperature structural materials.

High speed vaned centrifugal fans are widely used in several manufacturing and home appliances. For the designers the noise generated by these machines is one of the most important parameters to be reduced. The centrifugal fan used for this study is made up of an impeller, a diffuser and a return channel. The impeller turns at a relatively high speed about 35000 rpm. The objective of this study is to understand the mechanism of the noise generation within this type of machines. The contribution of the tangential and radial forces is highlighted. These fluctuating forces are due to the unsteady flow at the impeller-diffuser interface. The obtained result shows the effect of monopole and dipole sources on the overall noise.

Counter-rotating blade rows in single stage machines have been widely investigated in several applications like naval propulsion [1], axial fan [2] and axial pump design [3]. Previous publications have presented this design philosophy as a promising way to improve efficiency and cavitation performance [4]. Differently the goal of the presented design is to achieve lower required rotational speeds and at the same time a higher power density ratio, indirectly improving also the cavitation’s performance, aspiring actually to a compact design. However, a literature survey did not produce any evidence of significant advantage in axial-flow machines from this design philosophy in terms of machine power density. This paper presents a preliminary analysis of the applicability of the counter-rotating impeller concept on mixed-flow and radial-flow pumps. The design example presented in this paper constitutes a mixed-flow first rotor with a radial second rotor that rotates in opposite direction. A 1-D design model demonstrates that power density coefficient has a maximum for optimum speeds of the rotors range. The design example parameters were selected based on the highest power density coefficient and efficiency. Unlike most published literature where the rotor speed ratios are not fixed, instead the speeds can be independently varied through two separate electric drives. Both the front and rear rotor were developed using multi-streamline curvature analysis which combines fluid dynamic loss model [5] with a slip model at the rotor exit [6]. Several hypotheses were considered to determine the most significant and independent parameters that run through a response surface optimizer tool, scripted in MATLAB®. It detects optimum specific speed for the rotors which maximizes the benefits of counter-rotating impeller design compared to rotor-stator machine with same design point. Assuming steady numerical approximation error, the fitness function of the optimizer tool is based on steady state CFD results. The fitness function depends on total head and hydraulic efficiency, which show a maximum as a result. Optimum geometries were identified and one was chosen for manufacturing and testing in a test rig. Transient CFD analysis was also done to determine volute losses and incidence losses between first and second rotor and pressure pulsations generated. At this stage, manufacturing of hydraulic components of test model is in progress, while the mechanical design of the machine is close to completion.

Abrasive water jets have recently become a popular tool for mechanical machining. With its great advantages of geometric and material flexibility and its ability to cut hard-to-machine materials the technology is quickly spreading throughout many industries. With this near net-shape production becomes feasible, while significantly reducing the time necessary for secondary operations like programming, clamping, or tool changing. This allows a significant optimization of the overall manufacturing process chain. In this paper different approaches to increase the economic and technical efficiency of cutting with abrasive water jets are analyzed. Experimental analysis of the speed of abrasive particles show that the kinetic power of the particles mainly depends on the hydraulic power of the waterjet. Merely increasing the pressure of the jet did not yield any improvement in its acceleration capability. To obtain the most effective cutting performance a high level of hydraulic power through large nozzles should therefore be utilized. Additionally, recent advancements in cutting path control software have proven to significantly decrease the total ‘time to product’ and to increase the precision of the part. Those improvements in both software control and cutting power enable abrasive water jets to become an integral part of many industrial manufacturing processes. This will widen the scope of possible applications of this innovative and promising technology.

With the increase in computer-controlled hybrid machining (e.g. mill-turn machines), one needs to discern what features of a part are created during turning (i.e. with a lathe cutter) versus those created by milling. Given a generic part shape, it is desirable to extract the turnable and non-turnable features in order to obtain feasible machining plans. A novel approach for automating this division and for defining the resulting turning operations in a hybrid process is proposed in this paper. The algorithm is based on identifying the dominant rotational-axis and performing several non-uniform lateral cross-sections to quickly generate the “as lathed” model. The part is then subtracted from the original model to isolate the non-turnable features. Next, resulting model and features are translated to a label rich graph and fed into a grammar reasoning tool to produce feasible manufacturing plans. The setup design is also studied against the tolerances specified by the designer. Performance of the algorithm has been tested on several examples ranging from simple to complex parts.

After more than twenty years working on the selection of an appropriate expander for Organic Rankine cycles and wide research and attentions about its influence on the performance and total cost of waste heat recovery systems, now there is a good-enough background studies and achievement for large scale applications. But small-scale industries is like a art space to modify and revise the previous results. As it is clearly known, in small-scale applications and industries especially in internal combustion engines, besides the investigation of performance, physical properties and final efficiency of expander, other parameters should be analyzed accurately like manufacturing cost, availability, reliability, sensitivity to operating condition fluctuations. Due to a significant role of expander equipment to enhance the efficiency of ORC system in the first step expanders is investigated. In this paper, as per related operating characteristics, a complete comparison of small-scale expanders will be debated to guide designers to select more appropriate and the best efficient expansion machine as per their requirements. According to available literatures there is more need to do research about different types of expanders with various operating conditions in small-scale industries.

The paper has proposed to determine the equation of flanks of generation hook with oblong cycloidal arc taking into account two types of cutting tool: a cutting tool that generates the hole of the tooth, respectively a cutting tool that generates the tooth. The curved cylindrical teeth with cycloidal flanks is generated by rolling with straight mobile line and continuous division by using a milling cutter with 1, 2, 3, 4 or 5 groups of knifes equidistantly placed, fixed on an adaptable device on a Phauter toothing machine. The two curves which defines the flank are simultaneously generated by correlated motions. In order to make the analytical study of motions and geometry of the flanks, several 3D coordinating systems were first defined, each of them being bounded by an element that participates in the generating process. There were established the equations of cutting edged of the tool in Ss system, the equations of the flanks of the generating hook are obtained by changing the reference system of edges of the tool from Ss to SCG. The line of the flanks is studied in the reference plane and in parallel plans with this, and. the profile of the flanks is determined in perpendicular plans on the workpiece axis. . It was made a calculation program in MATLAB, that allowed to obtain data, which were used to plot the line and the profile of the flanks of the generating hook. By analysing the obtained shape they result conclusions used for the manufacturing of the involute-tooth gear with curved oblong cycloidal arc.
