Abstract : Manufacturing Execution System (MES) and Comprehensive Budget Management System are two indispensable management tools for automotive companies to further advance their informatization. Keywords : MES, Comprehensive Budget, Automotive Industry Informatization Needs Drive the Development of MES and Comprehensive Budget Manufacturing Execution System (MES) and Comprehensive Budget Management System are two indispensable management tools for automotive companies to further advance their informatization. Zhang Xinquan, CIO of Shanghai General Motors Co., Ltd., observes two unique aspects of informatization in the automotive industry: First, complexity. "A car is a major component with a complex structure, typically containing tens of thousands of parts. Different models are completely different, and even the same model has many personalized requirements. Therefore, from order approval to production planning, material planning, and sales, the process is quite complex." Second, high return on investment. "For the automotive industry, if the informatization system operates smoothly, it greatly helps improve business, with a very high return on investment. Whether it's reducing inventory or improving capital turnover, it can create enormous profits." However, given the current complexity of automotive company management and the high requirements of informatization systems... Manufacturing Execution Systems (MES) and comprehensive budget management systems have become indispensable management tools for automotive companies. MES's functions in areas such as shop floor control, data management, and inventory control will significantly alleviate the business bottlenecks of existing automotive management methods. Comprehensive budget management systems will comprehensively plan the logistics costs of automotive companies' Supply Chain Management (SCM) and achieve predetermined goals in stages. Many IT experts believe that the biggest challenge facing the automotive industry today is keeping pace with the rapid pace of user demand for personalization; the overall management system of the enterprise must also conform to this "adaptive" characteristic. At the same time, when dealing with the ever-changing growth of user demands, the most important thing for automotive companies is to effectively control automotive production costs and improve business performance. MES and comprehensive budget management can precisely solve these problems, significantly reducing automotive production costs, reducing inter-departmental coordination costs, ensuring vehicle quality, improving operational efficiency and customer satisfaction, and simplifying and rationally allocating enterprise IT resources. Furthermore, for the IT systems of large automotive groups, the phenomenon of information silos is severe. Over the years, enterprises have invested heavily in IT construction, but the lack of unified platforms has created various information silos, resulting in low efficiency. Even for the same business (such as equipment management), different secondary manufacturers commission different organizations to develop their information systems, resulting in incompatible business systems. The group company urgently needs unified management of each business system within the company and integrated application with other business systems. In the future, the implementation of e-commerce in the automotive industry is an inevitable trend. However, how to implement it must adapt to the continuous changes in China's economic development level and the management level and models of automotive enterprises. The construction of e-commerce informatization in automotive enterprises should adhere to the principle of "overall planning and phased implementation," avoiding a hasty approach. Information systems should not unrealistically pursue large-scale and comprehensive solutions. Therefore, under these circumstances, the demand for MES (Manufacturing Execution System) and comprehensive budget management systems in automotive and other manufacturing enterprises will become even more urgent. Below, I will only discuss some personal views on how MES systems and comprehensive budget management systems can play a role in the informatization application process of automotive and other manufacturing enterprises. MES continues to lead automotive informatization . MES systems build a "bridge" for information communication between the management informatization and industrial control automation layers of automotive manufacturing enterprises, playing an important role in improving production efficiency, strengthening production control capabilities, and reducing consumption. In 2007, the Chinese manufacturing MES application market entered a period of rapid development. Product applications expanded from large automotive manufacturers (such as automobile, steel, and chemical companies) to medium-sized enterprises in sectors like garment manufacturing, toy manufacturing, machinery processing, and non-ferrous metal smelting. Competition among domestic and international brands entered a phase of comprehensive strength assessment. Enterprise users became increasingly rational in their investment in MES products, demanding deeper considerations regarding product functionality, scalability, and system integration capabilities. Currently, automotive manufacturers are concerned with three questions: What to produce? How much to produce? How to produce? The company's production plan answers the first two questions; "how to produce" is controlled by the process control system on the production floor. ERP and CRM systems only provide data for production planning. For how the "plan" is transmitted to the "production" stage, and how changes during production are quickly reflected back to the "plan," a "real-time information channel" is needed between planning and production. MES (Manufacturing Execution System) serves as the "information hub" bridging planning and production. In recent years, with the emergence of new production models such as Just-In-Time (JIT) and Business-to-Order (BTO), and the increasing demands for product quality from customers and the market, Manufacturing Execution System (MES) has been rediscovered and gained renewed importance. Simultaneously, after the bursting of the dot-com bubble, enterprises began to realize that improving competitiveness stemmed from fundamental production management. This meant that only by extracting data from the product level (basic automation level), passing through the operation control level, and delivering it to the management level, achieving enterprise information integration through continuous information flow, could enterprises remain competitive in an increasingly fierce market. Currently, MES is being rapidly and widely adopted abroad. An enterprise information system is an interconnected collection of information. As the most important and fundamental activity within the manufacturing industry—production—its related information especially requires real-time processing and analysis. Specifically, this involves collecting large amounts of real-time data during the production process, processing real-time events promptly, and maintaining two-way communication with the planning and production control levels, receiving relevant data from both layers and feeding back processing results and production instructions. MES differs from traditional shop floor controllers, which primarily rely on work orders for production management and auxiliary material flow, and also from unit controllers, which focus on job and equipment scheduling. Instead, MES should be considered as a production model, integrating manufacturing system planning and scheduling, tracking, monitoring and control, material flow, quality management, equipment control, and Computer Integrated Manufacturing (CIM) to ultimately implement a manufacturing automation strategy. It is believed that in the near future, MES systems will continue to lead the way in automotive manufacturing informatization. Furthermore, in the downstream of the automotive informatization industry chain, MES will inevitably be organically combined with comprehensive budget management systems to leverage synergistic benefits. Comprehensive Budgeting Leverages Automotive Informatization Comprehensive budget management refers to the management behavior and control arrangements for anticipating (forecasting and planning) and controlling the future of investment, operating, and financial activities related to the company's survival. Automotive companies can use budgets to decompose and monitor the implementation of strategic goals, helping to ensure the achievement of sales revenue targets, control expenses, and predict the company's cash flow and profits. By implementing comprehensive budget management, a company's operating objectives can be clearly defined and quantified, its management and control standardized, the responsibilities of each responsibility center implemented, the responsibilities and rights of each level clarified, and the assessment criteria defined, thus guaranteeing the success of automotive companies. It can be said that the process of comprehensive budget management is the process of decomposing, implementing, controlling, and achieving strategic goals. "The budget itself is not the ultimate goal, but rather serves as a tool linking company strategy and operating performance. Based on resource allocation, the budget system is mainly used to measure and monitor the operating performance of the company and its departments to ensure the ultimate achievement of the company's strategic goals," said Yang Gongshe, Assistant General Manager of Foton Motor. This, from one perspective, illustrates that the era of comprehensive budget management in the automotive industry has arrived. Beijing Jiada Automotive Service Co., Ltd., established in August 1995, is a Sino-Canadian joint venture high-end automotive service company built in Beijing, with Canada's Jiada Technology Development Co., Ltd. as the main investor. It was among the first batch of authorized after-sales service centers of Shanghai General Motors nationwide. As a Sino-foreign joint venture high-end automotive service company established according to international practices and a modern corporate system, the leadership of Beijing Jiada Automotive Service Co., Ltd. deeply understands that with the increasing perfection of the market economy, in order to cope with the even greater challenges after joining the WTO, the company must have timely, accurate, and complete access to operational and management information, with financial information at its core; it must manage, control, and allocate various internal resources in a highly centralized manner; and it must make scientific decisions on various financial and management plans that maximize corporate value. What is currently severely restricting the competitiveness and overall profitability of my country's automotive dealerships? It is marketing and management issues. The backwardness of marketing is seriously hindering the development of my country's automotive dealerships; extensive management is no longer suitable for market development; therefore, improving the professional level of the marketing and management team is an urgent task. Considering the company's development strategy, the leadership of Beijing Jiada Automotive Service Co., Ltd. decided to select a software vendor as a long-term partner for the company's information technology construction. After multiple exchanges with Beijing Houdun Technology Co., Ltd. (hereinafter referred to as Houdun), and a comprehensive evaluation of Houdun software, we fully recognized the product value and professional advantages of Houdun's comprehensive budget management system for the automotive industry. We were also satisfied with Houdun's fast and efficient support system based on the principle of "software is service," and ultimately decided to use the Houdun comprehensive budget management system for the automotive industry. Houdun's comprehensive budget management system for the automotive industry implements a complete budget management system. The comprehensive budget management system designed and developed by Houdun for Jiada mainly includes financial data interfaces, budget template settings, budget preparation and simulation analysis, budget hierarchical aggregation and approval, budget adjustments, expense reimbursement management, management of procurement, requisition and payment processes, supplementary income and expenditure registration, budget execution control, budget analysis, budget evaluation, business indicator monitoring, and basic data maintenance—a complete closed-loop system with multiple layers of data. Houdun's comprehensive budget management system for the automotive industry enables flexible budget item settings and quick simulation calculations of budget forecast indicators. Its complete B/S architecture will truly achieve unified group-wide management and control. Meanwhile, HouDun Comprehensive Budget, as a third-party professional comprehensive budget management software, provides as many interfaces as possible with general financial software and supports customized multi-level responsibility centers and budget organizations, as well as professional secondary development services, fully meeting the personalized needs of enterprises. HouDun's automotive industry comprehensive budget management system is a process-driven fourth-generation collaborative comprehensive budget management software, supporting customized budget preparation, review, control, and other processes to achieve a collaborative mechanism across all branches and remote offices.

HouDun Comprehensive Budget Management is the core of financial management and a fundamental guarantee for achieving corporate business objectives. It will help enterprises formulate scientific and reasonable comprehensive budget plans based on their own resource situation and development potential, and achieve comprehensive control in all aspects of enterprise operation and management. By establishing a comprehensive planning and budgeting system, business operations among various departments can be effectively coordinated; business efficiency can be effectively improved by using comprehensive budgeting as a guide; the control role of the budget can be effectively strengthened; the budget preparation process becomes simpler, and the preparation cycle is greatly shortened; the budget implementation status can be analyzed in a timely manner, allowing for timely implementation of corresponding measures. Jiada Group once attempted to use financial software for budgeting and management, but the test results were unsatisfactory. This is because financial software can only summarize and analyze financial data after the fact, providing only results, which, once given, cannot be reversed. Financial software cannot address the issues of pre-event forecasting and in-event control. From a management and decision-making perspective, the company appears very passive and disadvantaged. The pre-event and in-event stages are precisely one of the weakest links in Chinese enterprise management and the most prone to problems; therefore, timely rectification is necessary. Comprehensive budget management software can help companies eliminate these loopholes, solve the problems of pre-event forecasting and in-event control, and basically meet the company's target management requirements. MES and comprehensive budgeting systems will be increasingly valued by automobile manufacturers. Reducing information silos, strengthening enterprise management, lowering costs, and mitigating risks will be the inevitable path for automobile companies to become information-based, and also a major strategy for the informatization of my country's manufacturing industry. It is hoped that MES and comprehensive budgeting systems can play an increasingly important role in more automobile manufacturers, and that my country's automobile informatization construction will flourish as well as my country's automobile industry.
