In this issue, the editor will bring you about the factors that affect the implementation of the cloud ERP manufacturing system. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

ERP enterprise resource planning is an enterprise-level management software, which involves all aspects of enterprise management. As a management system, the implementation consideration is not only the management ideas contained in the software itself, but also the inherent characteristics of the enterprise. In general, enterprises adopt the implementation strategy of overall planning and step-by-step implementation when implementing ERP, and most of them start from purchase, sale and storage. Relatively speaking, purchase, sale and storage is relatively easy to implement and easy to see the effect of several subsystems. Manufacturing system is not only the difficulty of ERP enterprise resource planning, but also the core part of ERP. Through the manufacturing system, the enterprise sales, procurement, inventory, cost and other management processes can be organically integrated. Software without planning and planning model can be called enterprise management software, enterprise process integration software, and anything but ERP, but it is not ERP, because we know that ERP is centered on planning.

According to all kinds of basic information such as sales order, sales forecast, finished product inventory, lead time and so on, the cloud ERP system selects the corresponding parameters and calculates the feasible production plan in the corresponding period. The calculation result of MPS is passed to other relevant plans such as MRP as basic data. More importantly, ERP transmits it to the corresponding production department as a production order to carry out the production task. In the process of implementing production tasks in the production department, ERP compares the plan data with the execution results, and checks the execution effect of the plan to find problems in time; for the inspection results, the experiences and lessons found are summarized into the planning model by means of revising the calculation parameters and revising the workflow.

This is the planning system of the cloud ERP system. The implementation of manufacturing system is not only a difficult point in the implementation of ERP, but also an important link between the preceding and the next.

1. The establishment of product structure tree is the key to the success or failure of ERP production subsystem.

In order to use computer to assist enterprise production management, first of all, the computer can read the product composition and all the materials involved. In order to facilitate computer recognition, the product structure expressed by diagram must be transformed into a certain data format. This kind of file describing product structure in data format is the bill of materials, that is, BOM. It is a technical document that defines product structure, so it is also called product structure table or product structure tree. BOM (Bill of Materials) is the most critical unit of the cloud ERP system, which determines the success or failure of the successful operation of the manufacturing system and the most important basis for product quotation, so enterprises should first establish the product structure tree before implementing the ERP manufacturing system.

There are two ways to establish the product structure tree, one is that the enterprise has implemented the PDM system and established the design structure tree in PDM, and then the product structure information and product material information are transmitted to ERP through the integrated manufacturing interface between PDM and ERP, and transformed into the engineering structure tree needed in ERP through the definition of process parameters. Another way is that the enterprise does not implement the PDM system, define the material information directly in the cloud ERP system, establish the engineering structure tree, and define the relevant process parameters to form the engineering structure tree needed by ERP. Because our enterprise has implemented the PDM system long before the implementation of the cloud ERP system, our enterprise is the first way to adopt it. By comparison, I think that the first way is the more advantageous way to establish the product structure tree. Many enterprises do not implement the PDM system when implementing the cloud ERP system, but after the implementation of the cloud ERP system, they will unanimously choose to continue to implement the PDM system, because the PDM system is the data source of the cloud ERP system, without the support of the PDM system, the material data needed by ERP, especially the product structure information, can not be effectively generated, or can not be easily generated. The PDM system adopted by our enterprise is SMARTEAM, and the cloud ERP system adopted is RS10 of Beijing Machinery Industry Automation Research Institute. The organic combination of the two systems not only determines the convenience of the establishment of our enterprise's product engineering structure, but also provides a strong guarantee for the correct operation of our factory's manufacturing system.

1.1 the establishment of design BOM is the foundation.

Design BOM is a design product structure tree established by engineering designers according to product requirements in the PDM system. In this structure tree, there are basic information of product materials, product structure level information, product quota information and part of product process information. Of course, the most important part of this information is coding, which is the most basic work of engineering data preparation before the implementation of cloud ERP system. For discrete manufacturing enterprises, there are many kinds of products, multi-variety, small batch, multi-variety and large batch, hundreds of series and thousands of specifications, so the establishment of product design BOM is a complex and tedious work. If you want to build all the structural trees at once, it will be very difficult. Our enterprise still adopts the strategy of step-by-step implementation when establishing the design structure tree, establishing the product structure tree according to the product series. First of all, the most basic product series is established, and then a product structure tree of other series is completed in each time period, which completes the establishment of the design BOM step by step. Through the analysis of the product structure of the enterprise, I feel that most of the products of the enterprise are derived from the basic series of the standard, and the differences between the products of the basic series of the standard and the basic series of the standard are generally only about 5% and 10%, while the remaining 90% or so are exactly the same. Therefore, by establishing the standard basic series product structure tree first, and then shortening the process of building trees, it is a good way to build trees.

1.2 Engineering BOM conversion is the key to production planning and operation.

The engineering BOM is redesigned by the process engineer to the design BOM according to the processing level and capacity of the factory. It is used in process planning and manufacturing management. using it, we can clearly understand the manufacturing relationship between parts and parts, and track how the parts are manufactured, where, by whom, with what and so on. At the same time, engineering BOM is also one of the key management data structures of MRP Ⅱ / ERP production management.

It is convenient and quick to define engineering BOM in the RS10 cloud ERP system of Beijing Machinery Industry Automation Research Institute. The basic material definition interface is provided in the software, which can conveniently define the basic material information, warehouse information, financial cost information and production planning information. In addition, ERP provides interface table data transmission, including material data transmission, product structure information transmission, process route information transmission. Through the interface, the product structure information, material information and process information in PDM can be transmitted to the cloud ERP system. Such an engineering BOM that can be used by ERP is established.

The four steps determined by 1.3BOM

Usually, to determine a final correct BOM, there are four steps: the first step is the establishment of the design BOM; the second step is the transformation of the engineering BOM; the third step is to verify the operation plan; and the fourth step is to correct the feedback problems. It takes four steps to determine the accurate and complete product BOM. This process is generally impossible to omit, especially in the verification stage, through which the integrity of BOM structure information, the accuracy of quota and lead time, and the correctness of process route setting can be verified. Only through the actual planned operation and the specific application of the actual manufacturing process can these parameters be finally verified and fed back.

2. The definition of lead time determines the accuracy of the plan.

When we implement ERP's MPS/MRP plan, we must first consider the processing cycle of its products, which often has two methods: one is to take the lead time as a constant, of course, the average lead time of the average batch is considered in advance. Second, the lead time is regarded as a dynamic number, which changes with the change of batch. The advantage of the first method is that it has less impact on the lead time of procurement, and the procurement is ordered on a first-come-first-served basis to give first-needed production orders. Production input, work-in-process backlog is small, however, for the duration of production orders, we need to rely on the capacity plan CRP analysis to make a large number of adjustments.

The advantage of the second method is that the lead time varies with the batch. Lead to the order of feeding first and then output, causing work-in-process to pile up in the workshop. For semi-finished products, the change in the cycle of one half of the finished products will lead to the waiting or lag of other semi-finished products, which will also have a great impact on the procurement plan. Often occurs after the purchase order of the material, but the first arrival.

Usually, when enterprises implement the manufacturing system, it is set up in the first way. According to the previous experience in the production process, the production management department and the material purchasing department of the enterprise set the average lead time of self-made parts, external contract parts and purchased parts respectively. Because the lead time itself is an empirical value or a statistical value, it is meaningless to pursue the accuracy of the lead time too much, and there will be a certain gap between the results run through MRP and the actual plan. This requires the production dispatcher to adjust and modify the tasks of the workshop. In ERP, we often use MPS master production plan adjustment strategy to balance the actual unstable quantity, so that the batch of orders placed is consistent. To keep the production lead time approximately unchanged, and gradually reduce the MPS master plan batch. The purpose of these measures is to reduce the inconsistency between the ERP plan and the actual plan.

3. The definition of virtual parts simplifies BOM and facilitates plan management.

Virtual parts: a virtual part is an unstocked assembly that combines the materials needed by its master parts to produce a sub-assembly. The MRP system can be directly expanded to the sub-parts of the virtual part through the virtual part, just as if these sub-parts are directly connected to the master part of the virtual part. When calculating the product cost in the cost management system, the assembly cost of the master parts of these virtual parts will include the material cost of the virtual parts, but does not include the cost elements such as labor and manufacturing costs.

In general, we will set the following two cases as virtual objects:

1) products or materials that do not exist in the actual business, such as the brush grip device inventory on the motor (composed of brush grip, brush rod and brush rod seat), are composed of several packages. In fact, the virtual parts have been automatically converted into product packages by the computer when picking up the materials.

2) in order to simplify the BOM, the BOM combination which is relatively fixed but does not exist in reality is set as a virtual product, and the virtual parts have been decomposed automatically when placing the production order. The definition of virtual parts simplifies BOM and greatly facilitates the management of production planning.

4. The secondary development of management optimization is the promotion means of implementing ERP production subsystem. The secondary development of management optimization is the icing on the cake in the implementation of ERP. It is some simple development in ERP software made by enterprises according to their own management needs. There are a variety of contents involved, and menu, page or report functions are usually added to the system. These developments make it convenient for enterprise managers or system users to query or count relevant information. The RS10 of Beijing Machinery Industry Automation Research Institute is easy to develop, and it can use simple SQL statements and JAVA language to make menus, pages or reports that enterprises need. For enterprises implementing cloud ERP system, the development of some applicable reports or pages can not only ensure that users will not deviate from the original way of work, but also greatly improve the interest of users.

The success rate of ERP implementation is not high, and the implementation of ERP manufacturing system is the key. Scientific and feasible planning system is the essence of ERP, and it is also the fundamental reason why enterprises can produce benefits by applying ERP. A big difference between ERP and the traditional management information system is that it has advanced management ideas-a variety of scientific planning models. ERP is more than simply inputting documents and querying statistical reports. The pre-test model based on statistical principles, the planning model designed according to management principles and resource constraints, and a series of related processes around planning are the core that we need to study and pay attention to. In addition to the above points that should be paid attention to in the implementation of the production system, the timing and mode of the integrated interface between the manufacturing system and the warehouse should also be taken into account. and the impact of the planned and planned batch on the finished product warehouse and sales out of the warehouse, these problems seem simple, but if the implementation is not fully planned and considered, it will affect the implementation process of the system. And users' confidence in the system.
