Research on Main Production Schedule in ERP

The subject of the main production schedule is the specific product in production lines, known as the final product (End Item). The final product is usually independent demand items.  The meaning of the final planning objects is not the same, due to the different sales environment. The MPS(Main Production Schedule ) is vary due to the different production method, here introduce several commonly used production methods:

1. Make-to-Stock (MTS) : usually the products in direct sales circulation .

2. Make-to-Orde (MTO) and Configuration to Order CTO) : the final products are generally the standard stereotypes products or products designed to the requirements of orders, usually the final products are in  0 layer of the product structure.

3. Assemble to Order (ATO). The products are modular structured, can be in a variety with choice, we use the final assembly schedule (FAS) Schedule to arrange manufactured products, the development of common parts, use the MPS and BOM to make plan on the basic components, optionals and multilayers.


Make-to-Stock and Make-to-Orde are widely applied in production of China; at the same time, for production planning purposes, there are no essential differences between MTS and MTO . Therefore, in the WERPTS environment, use the universal MTS as the typical production method to build production management systems. There are 2 styles of Schedule in the MTS and MTO: fixed period Schedule and rolling Schedule.

Fixed period Schedule is the primary mode of some enterprises. Each time, characterized by a relatively fixed time,  develop the next planning cycle production Schedule. Planning cycle of the traditional manufacturing enterprises are mostly quarter or month, as companies gradually increase the ability to the response of the market, the monthly Schedule and weekly Schedule has become a major planned way in modern manufacturing enterprises.

Rolling Schedule is a plan raise in recent years, it was originally used for the preparation of long-term planning, such as variety product development plan. This Schedule combine the long-term Schedule and short-term Schedule,  with the passage of time and changes of objective conditions, long-term plan is amended, while short-term Schedule is developed to has a long-term goal.


Rolling Schedule increase the planning cycle by the roll of Schedule , make it is possible to coverage its long production cycle. In addition, the method is revised  according to the changes in external conditions and the implementation of the plan. Through the dynamic Schedule,  will become pre-control on part after the control, reduce the afterwards coordination work, and improve the passive situation of the original Schedule.

In view of the above advantages of the rolling Schedule, the ERP software part in the ERPWTS, we select Make-to-Stock on production, and choose rolling Schedule as the model.

Web-Based training mode composed of case and Situational Experience

The online training model based on case experience is a new training model on the basis of case and the experience, the main elements of if include 3 parts: the real case, the experience scenarios , and the interact.
Case study is a kind of the  descriptive text, usually presented in the form of narrative, which is based on real life situations or events. These case always try to carry the background events, information of participants, and strive context authenticity objectively and multidimensional. According to this definition, there are two levels of understanding, first of all, the case must be true, and other, the case is multidimensional.
Case experience take the real cases, can be in multi-dimensional forms. Various case experience forms: one is the overall background information to give students the global guidelines on the experience process, there is a corresponding case to the specific practice, the case may be just a simple physical objects too.

Experience situation is to build a context for students to experience the training, case experience and experience of case must be closely to the real situation.
Apply this mode on ERP training, we use this form to build a typical web-based ERP software platform for practical operation experience, the case is the typical case of real ERP implementation, this help students have a holistic grasp and understanding. There is software operation prompts information during specific operations, including the relevant background and some small cases for the current operation.

Apply this training mode on ERP application, it build real situation and cases for training; on the other hand it solve the problem that there in only few contextual information on ERP software training, reduce the students subjectivity  of experience, it can improve efficiency and accuracy of the training. The comparison  of this model with other common patterns is the follow:

The Chart of  Training Models Comparison

ITEMS Web-Based Model Combined the Case and Stuational Experience Normal Web-base Model Classroom Model On-site training mode
Methods Case Experience Lectures, case, audiovisual Lectures, case Environment practice
Freedom of learning High High Normal Low
Learning costs Low Normal High High
Training Effect Good Normal Normal Good
Model Complexity High Normal Low Normal
Scope Normal High High Normal

The online training model based on case experience is an ideal training model. However, in practical application, since the pattern is complex, which may be the limiting factor in the promotion of the pattern.

This model is particularly suitable for technology training when it is able to build a true network platform and . Apply this mode on ERP application, we can build the platform for ERP software practical operation, and this is the key ERP training, so the model based on case and situational experience in the ERP training is a viable mode the ideal application.

ITS Time to apply online training on ERP Applications

With the rapid expansion of the ERP market, the shortage of the professional ERP talents is also becoming increasingly apparent, the lack of talents has become the main constraint of ERP implementation, how to train professional complex ERP talent become an important strategic task of the educational institutions and the whole society. ERP software talent include the following: persons engaged in the development, maintenance or implementation of the project, as well as the guys who apply ERP software products in business management successfully. They not only understand IT, but also manage, familiar with the industry’s requirements.
ERP talents needed now are divided into two parts, firstly the ERP professionals, such as the company’s ERP software implementation consultants, these people must be the talents on technology and management. On the intellectual level, a qualified adviser of the ERP implementation must have financial knowledge, computer knowledge and management knowledge; in terms of experience level, there should be with some corporate governance practices, know the industry R & D, production planning, purchasing inventory, financial, sales, human resources, one or more of the management process. So many good ERP consultants are not only professional on computer, most of them are switched from the corporate management positions. But the most widely demands are the users of ERP application softwares, such as staff ERP applications business related positions. From an application perspective, all staffs of the ERP implement should be trained and guided on ERP skills, therefore, the demand of the talents on ERP application is never saturated.
At present there are more than 300 million enterprises in china , assuming that 8,000,000 companies want to implement ERP in next five years, each user needs an average of eight weeks to implement, and the consultants of the implementation work 50 weeks each year, so We need at least 25 million ERP implementation consultants; every enterprise ERP implementation needs  3-5 employees at least who understand the basic principles of ERP and are skilled on operation and maintenance of ERP-based personnel-related tools, then in the next five During the year, we at least need 20 million more of the basis ERP staffs.
Faced with such a large market, the current domestic ERP training is still in the promotion stage. This industry is not only the lack of a unified authentication system, but the quality of ERP personnel is also uneven , it bring lots of difficulties on the ERP application ,  because the development of ERP application market is not perfect, the education and  huge investment on training market is prohibitive factor.
Web-based training model not only broke through the limitation of time and space. Students can learn anytime, anywhere, it is flexible,  time-sensitive, and affordable, online ERP training has broad prospect. Currently, the ERP training of network  is usually electronic versions of traditional textbooks, or the multimedia of ERP software operation, the training effect is often ignored.
Compared to other professions and skills, ERP personnels, especially basic ERP software operation personnels, are more emphasis on the actual operation. ERP training is not only to impart knowledge of ERP, but also should teach them the thinking of ERP implementation, the most important for ordinary operators is the specific procedure of the ERP software training and operational processes.
Although there are a number of ERP online training platform based on the use of multimedia, they ask participants to install the ERP software to enhance practical experience of ERP software operations, but the consequences is charged too much, and interactive between students and ERP software experiences is poor.
In this article, i would like to introduce a new training plate. It is based on  the construction of good WEB-ERP operating experience, combined with case notes and the operation message prompts, the case law and situational experience. There is great practical significance to alleviate the lack of personnel and training on ERP training and application.

The Status of online Training and ERP training

The development of technology is faster and faster, people must continue to learn in order to face the increasingly fierce social competition. Information technology rapidly changes the society, but also provide people more convenient  learning opportunity. As the main carrier of modern remote training, multimedia and distance education network conforms to the development trend of the times, give people convenient and powerful support . Today, the global annual number of people receiving education and training through the Internet is more than 150 million. In the United States, continuing education and training costs accounted for 10% of GNP of the United States, and the proportion is still rising up. Network-centric online training (e-Training, e-Learning) is becoming a global trend of education and training.
Distance vocational training is an new form of educational organization in the information age, it was developed in the Learning Society with a geometric exponential growth of the scientific and technological knowledge, all the countries take great attentions to modern distance education, all try the best to establish the modern distance education mode, lifelong vocational training system and work patterns.
The United States is the largest country in the current distance vocational training scale. America view the network diploma same as the traditional school degree, more and more universities recruit students, send diploma via the Internet.  In 1995, only about 28% of universities offer online courses, but soared to 60 percent in 1998; According to statistics, the annual growth rate of the american online training number reach up to 300%,   more than 60 percent of enterprise take the network training and continuing education for employees.
Britain’s Open University is wide open to the whole society and the world. It has no entrance examination, combine the degree education and lifelong education mechanisms, and use credit management. From primary education to higher education, graduate education, each level of training is available. The training is based on the network, adopt multimedia teaching environment and the application of CAI. In addition, in 1998, the British government issued the legislation that students in the primary and secondary schools should learn the information courses,  the statutory should use more than 6% of the government investment in education funding to spend on the purchase of the computes, in order to ensure that UK primary and secondary schools can be connected to INTERNET.
Not only developed countries attach importance to distance education and remote training, remote training in certain areas of some developing countries  has reached a certain scale. Take the Indian IT vocational education for example, the Indian governments encourage and support the domestic and foreign private capital to be involved in IT vocational education in a variety of operations. Besides these, the characteristics of the Indian IT vocational education is the following:  after the completion of basic education, students can  be implemented the personnel training, even without any higher education, it shorten the culture period, reduced the cost on using cultivation of talents.
Relative to developed countries, China is late on the development of distance education and training. The late 1990s is the strategic innovation, universities and colleges carried out two-way interactive TV education and the computer network distance education; Radio and TV Universities have made significant progress on openness, modernization, and the cooperation with schools and colleges; the government decided to implement the Modern Distance Education Project and Construction of Distance Education Network to promote the popularization of higher education and lifelong learning forming system and lifelong learning society.
Tn December 2001, the China Distance Education Technology Standards International Symposium Party was conducted in Beijing, it released of “Modern Distance Education Technology Standard System Introduction”, which pointed out: The Chinese distance education technology has been in a new web-based stage: the emergence of a large number of the country spontaneously campus primary and secondary education; in adult education, the existing education system transferred their attention to the network.
In recent years, due to the rapid development of information technology, network penetration and application in various industries, China’s distance education and training business is developing rapidly.There are only 6 Network University in 1998, but by 2004, the number reach up to 68,there are more than 150 million students in these universities.

While ERP are applied more widely, the failure cases of the ERP implementations in enterprises increase a lots,  enterprises gradually become more aware of the importance of personnel training on ERP implementation, as well as there is a huge demand for qualified persons who are familiar with the ERP. Because the cost of traditional training mode is expensive and inflexible, online ERP training also continue to emerge in recent years .
Due to the complexity of ERP, though there is some development on online ERP training, most of the platforms are presented in the form of lesson plans, the training result is poor; there are some multimedia online ERP training platforms , to a certain extent, they improved the interactivity and efficiency of online training.

The Questions of the ERP Application in China

A lot of research and practice show that any kind of science and technology can be quickly converted into real productivity through the effective application, there is no exception on ERP(Enterprise Resource Planning). Therefore, study the common problems and constraints universality of ERP application and development in our presence, and reach a consensus,we can improve our ERP application level fundamentally, and improve enterprise management level and competitiveness of enterprises, it is very important for us to meet the challenges of e-commerce revolution networks. These common and widespread problems are in the following aspects:
(1) ideological misunderstanding
On the review of the concept of ERP, some companies think ERP as the enterprise information construction, even worse, the ERP is only viewed as the construction of a computer hardware, software and Internet systems.
Many companies think the ERP project as enterprise information construction , ignore that it is an enterprise management system works, so they failed to catch with the right purpose of the implementation of ERP; some state-owned collective enterprises purely want to meet the level of enterprise information requirements, there are some enterprises blindly following the trend, so these enterprises run the ERP system not based on enterprise management, they failed to combine the application of ERP , deepen reform, management innovation, application of modern business management ideas and methods closely integrated .
When ERP process is implemented, they think that all are finished after they adopt any.  Some of them focus on the applications of the information technology applications and the selection of the ERP software; Business Process Reengineering, business requirements analysis, training and education , modern enterprise management are ignored
(2) the inappropriate choice of the technical route
When selected the specific ERP solution, companies failed to carry out the scientific management of ERP projects, such as the development of clear, quantifiable goals on ERP applications, the research on ERP project feasibility, which made the companies likely to choose feasible ERP plan or a system not matched with the enterprise technical route. Some ERP users do not have their own consulting team, and there are no any relevant supervision departments. When ERP was processed,  companies did not understood “customer service” concept well, blindly obeyed the requirements of customers, which directly made the technical route being used improperly, ERP systems keep rising  problems, the result  is that ERP even become a burden on businesses.
(3) The guarantee system is not perfect
Most of the Chinese enterprises are in low level of corporate management, the production system is not standard, the accuracy and timeliness of the underlying data is very poor, and the production process is not stable, so that ERP failed to play the important role as it should have, some companies are not able to guarantee the normal operation of the ERP systems.
Most enterprises failed to establish the appropriate operational mechanism when the ERP sytem is processed, they do not have the ability to adopt effective management of ERP projects, such as the establishment of corporate staff training system, the implementation of business process reengineering, the establishment of quality assurance system, the establishment of ERP Application performance evaluation system, and so on.
