Prospects for replacing production lines in the shipyards workshops with multifunctional assembly and welding manipulators

Some aspects for improving the technical level and flexibility of assembly and welding production of domestic shipyards are discussed in the paper. It is noted that a number of shipyards have integrated mechanized production lines of foreign manufacturers: for metal processing, manufacture of ship hull structures, their painting, etc. As a rule, such lines are equipped with high-performance technological equipment; however, they are ineffective in conditions of small-scale production. The main reason is insufficient line loading. An alternative to such lines can be multi-functional complex mechanized and partially automated assembly and welding manipulators, which are a flexible production module equipped with an assembly and welding portal (or semi-portal) and a set of replaceable mounted assembly and welding equipment. The research purpose is an increase in the technical level and flexibility of assembly and welding production of domestic shipbuilding enterprises in the short term by replacing resource-producing and inefficient due to insufficient loading of mechanized production lines of foreign production with import-substituted multifunctional complex-mechanized assembly and welding manipulators. The subject of the research is a flexibly reconfigurable production system of a shipyard. Mechanized production lines of assembly and welding production and complex mechanized assembly and welding manipulators are accepted as objects of research. As a result of the research, the functionality of assembly and welding manipulators for the assembly of ship hull structures and a set of factors influencing the choice of their design schemes are determined. It is concluded that due to the extreme urgency of the issue considered in the paper, it is necessary to conduct a set of special studies on the theoretical justification of replacing inefficient mechanized production lines with complex mechanized multifunctional assembly and welding manipulators, and a range of priority tasks to achieve this goal is defined.

Block workshop spatial scheduling based on cellular automata modelling and optimization

AbstractBlock fabrication is the process that has the greatest impact on shipbuilding efficiency, so block spatial scheduling is widely studied as the key to improving shipbuilding efficiency. The shipbuilding spatial scheduling problem addresses the coupling characteristics of time and space. It is difficult to balance these two aspects. Based on the characteristics of spatial scheduling problems in shipbuilding enterprises, a three‐dimensional space that uses time as the third dimension is imported, and a cellular automata model along with some evolutionary rules is built, which includes shape optimization rules, cluster or edge rule‐based layout rules, and First Come First Service dispatching rules. The objectives are to achieve the minimum total completion time, the largest utilization of space and machine, and the least number of delay blocks. Taking the real data in a block workshop of a shipbuilding enterprise as an example, the feasibility and effectiveness of the algorithm are verified by comparing the statistical analysis with other algorithms.

Research on Lean Shipbuilding and Its Manufacturing Execution System

Abstract Based on the work breakdown structure theory, the lean shipbuilding method guided by intermediate products is proposed in this article. The hull segment task package is divided according to the content of the shipbuilding operation. Considering the constraints of resources and personnel at the production site, the scheduling strategy of the task package is formulated. Moreover, a virtual flow production system of the shipbuilding workshop is established. On this basis, a lean shipbuilding manufacturing execution system for small and medium-sized shipbuilding enterprises is developed to achieve lean production in a shipbuilding workshop. The application results indicate that implementation of the lean shipbuilding method and manufacturing execution system can significantly reduce the ship production cycle and the number of operators, as well as improve the production efficiency. Introduction In recent years, to resist strong international competition, manufacturers are under great pressure to develop products more efficiently and economically (Nam et al. 2016). The ship manufacturing industry, which faces fierce market competition, helps many nations’ economic systems (Rahman & Karim 2015). For example, the shipbuilding industry contributed over $37 billion of the Gross Domestic Product (GDP) to the U.S. economy in 2013 (MARAD 2015). Currently, China’s shipbuilding industry is in a downturn. If the shipbuilding enterprises want to survive and improve their competitiveness, they must reduce labor costs and shorten the production cycle. Lean production is a type of management philosophy born in Toyota Motors. One of the lean thinking goals is to eliminate waste, which can increase work satisfaction and turn waste into value. It should be emphasized that lean thinking must go beyond the company. In other words, lean thinking has to be employed from the product design to the set of activities delivered to the end customer (Barbosa 2014). Lean manufacturing technology focuses on eliminating all types of waste in the manufacturing process and reducing the lead time (Zhu et al. 2019).

Research on Dynamic Cooperative Replenishment Optimization of Shipbuilding Enterprise Inventory Control under Uncertainty

Aiming at the problem of high inventory control costs of shipbuilding enterprises under uncertain conditions, this paper constructs and optimizes a dynamic collaborative replenishment model of shipbuilding enterprises inventory control. This model adopts integrated supply chain management theory and collaborative theory to analyze the inventory control principle in shipbuilding enterprises, and its goal is to minimize the cost and maximize the service level. The dynamic replenishment strategy from two types of suppliers is given by using mathematical knowledge, such as optimization theory, probability theory, and mathematical statistics to solve the model. Finally, shipbuilding enterprises take paint inventory control as an example to test and verify the validity and correctness of the model by using numerical simulation and sensitivity analysis. The results show that the dynamic collaborative replenishment model of shipbuilding enterprises inventory control can make full use of the advantages of two types of suppliers. Additionally, it cannot only quickly respond to demand changes, but can also maintain low operating costs. Therefore, the dynamic collaborative replenishment model could effectively solve the problem of high inventory control costs of shipbuilding enterprises under uncertain conditions and has great application value and practical significance.

What Affects the Growth of Military Enterprises in China: Research and Development?

Sustainable growth of military enterprises is key to developing the national defense industry. Therefore, we selected the financial data of 90 military enterprises listed in China. Using the factor analysis method, we obtained the growth evaluation index from the four dimensions of profitability, debt repayment, operation, and R&D (research and development). The results show that R&D is the critical factor for the growth of military enterprises, and profitability is a short board. In the industrial field, the growth of military shipbuilding enterprises is better than that of other fields, mainly because of the high attention paid to R&D. Regarding the conversion of military-oriented enterprises to civilian production, this study emphasizes the importance of improving profitability and ensuring scientific research incentives. The results of this study are also consistent with the stock market performance of military-listed enterprises, which means that the higher the growth score, the better is the market performance. At the same time, the growth evaluation results of military enterprises have guiding significance for enterprises and market investors.

Research and Implementation of Lean Production Mode in Shipbuilding

This paper studies the production process of a shipbuilding enterprise. The company suffers from long manufacturing cycle, low utilization rate of personnel and an unbalanced production line. To solve these problems, the lean shipbuilding mode, mainly divided into shipbuilding work breakdown, production plan and virtual flow operation in this paper, is put forward, which combines the lean production and modern information management technology with shipbuilding. Supported by the theory of work breakdown structure and task package scheduling, the shipbuilding task package is reasonably divided. The priority of task package manufacturing is determined by calculating the task package manufacturing sequence coefficient, and a reasonable number of operators is calculated to ensure the continuity of segmented manufacturing. After determining the manufacturing priority of the task pack and the number of allocable personnel, the corresponding work can be scheduled. Production planning drives all production activities of the shipbuilding enterprise, and just-in-time production is achieved through the reasonable arrangement of these production plans, thus reducing the waste of personnel and time. Then, the virtual flow operation is carried out, which can achieve high efficiency of flow production and high flexibility of fixed workstation production during the production process of large-scale and heavy-duty products. The virtual assembly production system of the workshop is established according to the characteristics of shipbuilding operation and the actual production situation. On this basis, a lean shipbuilding manufacturing execution system for small and medium-sized shipbuilding enterprises is developed to achieve lean production in a shipbuilding workshop. Through the implementation of the lean shipbuilding mode based on task package scheduling and its manufacturing execution system, compared with the original data, the ship production cycle is reduced to 76.7%, the number of workers is reduced by 16.7% and the production balance rate is up to 81%.

The article presents the key principles for the design of net-centric information management systems at civil shipbuilding enterprises (scalability, reliability, adaptability, and data unification). It also suggests the tools for their implementation, in particular a local module for the calculation of the production cost of a standard waterborne vessel. Conclusions. The digitalisation and automation of calculations based on net-centric information management systems allow for the orderly transmission of data flows, which, being processed and thoroughly analysed, serve as the basis for effective managerial decisions.

Supplier Selection of Shipbuilding Enterprises Based on Intuitionistic Fuzzy Multicriteria Decision

With the increasingly fierce competition in the global shipbuilding industry, shipbuilding enterprises need to maintain competitiveness and cope with rapid changes. In this case, shipbuilding enterprises need to establish effective supply chain management. Among them, choosing the right supplier is one of the most critical activities. The supplier selection of shipbuilding enterprises is considered a complex multicriteria decision-making (MCDM) problem that attracts much attention due to intuitionistic fuzzy sets to deal with possible imprecision and fuzziness in real life. Based on this, this paper proposes a new method based on the intuitionistic fuzzy SWARA (stepwise weight assessment ratio analysis) and COPRAS (complex proportional assessment) method to select shipbuilding enterprise suppliers which is a new research area. First of all, different weights are given to each expert evaluation result according to their position, educational background, and working years. The supplier index’s weight is determined based on the intuitionistic fuzzy SWARA method, and it is easy to understand and operate. The ranking of suppliers is determined by the intuitionistic fuzzy COPRAS method. This method considers all kinds of uncertainties and evaluates the utility index and the cost index of alternative suppliers. Finally, taking a shipbuilding enterprise as an example, applying the intuitionistic fuzzy SWARA-COPRAS method is illustrated. Compared with other methods and sensitivity analysis, it shows that the intuitionistic fuzzy multicriteria decision-making method is effective and stable in shipbuilding enterprises.

MECHANISMS OF OPERATIONAL PORTFOLIO MANAGEMENT OF PROJECTS IN SHIPBUILDING AND SHIP REPAIR

Over the past decades, the competitiveness of enterprises in the world shipbuilding and ship repair markets is being determined by the level of development of information and communication technologies, on the basis of which global value chains are being formed. The shipbuilding 4.0 methodology is being introduced in the industry, which is based on the advanced technologies of the fourth industrial revolution. The aim of the article is to study the models and mechanisms for portfolio management of shipbuilding and ship repair enterprises on the basis of modern information technology for the effective implementation of strategic goals and sustainable development. The basis of the organizational and methodological support of portfolio management of shipbuilding enterprises is a system of planning and accounting units. This is a three-level model for the shipbuilding work breakdown. The first level of work breakdown consists of shop stages (list of works performed by a certain production department). The second level of work breakdown is technological sets that are being formed in the process of production planning on the principles of structural and technological unity of work and are the basic elements in the intershop operational management. Technological operations are carried out at the third level of work breakdown (brigade sets). At the upper levels of shipbuilding work breakdown, all the key features of project management take place. Technological sets are recommended to be used as an information and analytical basis when developing the network models at the upper levels of structural work breakdown. The methodology for portfolio management of projects of a shipbuilding enterprise described in the article is aimed at aligning the goals and objectives of individual projects and the portfolio as a whole with the strategic plans of the enterprise.
