Problems to be dealt with in production planning of networked enterprises

(1) http://www.aliyun.com/zixun/aggregation/38653.html "The Long whip effect of > information transmission." In the cooperation around customer orders, many enterprises are involved, each from its direct upstream company order, and then semi-finished products to downstream companies, including upstream and downstream of the order problem. Because networked enterprises span different enterprise organizations, these enterprises are geographically distributed, in the information structure is heterogeneous, in the computational processing is distributed parallel, these distributed, heterogeneous and parallel processing information in different and caused the information transmission process, because the different management of the requirements of different understanding, The distortion of information transmission is caused by different processing modes, that is, the demand amplification phenomenon. When the enterprise uses the demand information from the downstream enterprises to make the production plan, because the demand information has been deviated, and then through the processing of the enterprise, the production plan to the upstream enterprise needs more deviation from the actual demand.   This step-by-step demand information ultimately leads to the execution of production plans between partners that are not synchronized. The long whip effect of this kind of information transmission is mainly due to four factors, that is, ordering batch strategy, shortage strategy, demand modification and price fluctuation. The commonality of four factors of bullwhip effect is the inconsistency of partner program, fragmented plans and the implementation of the plan and other information can not be timely conveyed and the process caused by this amplification effect, the result is a network of enterprises lack of flexibility, resulting in relatively high operating costs and lack of responsiveness, and ultimately lose the market, the loss of customers. From the management point of view, the relationship between these joint ventures is temporary, dynamic, the joint venture is a strategic partner of interest, after the dissolution of the network enterprises are competitors, and even in a network of enterprises to produce some products, but also in different networked enterprises to produce other competing products, As partners and competitors, it is impossible to share information across the spectrum.   (2) Unified problem of data model. Production planning requires a certain amount of static basic data and dynamic real-time data. In a single enterprise, production planning data from two aspects, one is static resource information, resource information is production planning decision-making constraints, is about the enterprise resources of the existing data, from the short term, a single enterprise resource mind is fixed, and thus can be treated as static information The second is the demand information from downstream enterprises or users.   In networked enterprises, the constraint conditions of enterprise production planning have been relaxed, that is, all the factors that can be used for production have been expanded, and enterprises can consider utilizing the resources of other enterprises outside the enterprise. At the same time, enterprises used to develop production planning and control of the information also increased significantly, the upstream and downstream enterprises, resources, demand, supply and other information are enterprises must consider. This information integration must take into account the information between the various enterprisesThe unification of patterns. For example, different enterprises for the same information often for their own convenience and different description, manufacturing enterprises from their own production management perspective to consider the various detailed specifications of their products different sales, in order to arrange production planning. Retailers, by contrast, are counting the total sales of various products without taking into account a variety of detailed specifications. If the manufacturer gets the information without specific specifications it is very difficult to deal with, it can not be used as the basis for scheduling production plans.   (3) negotiation issues. The traditional decision mode of production planning makes a centralized decision based on "control power", which is the production decision in the framework of single enterprise, and the decision plan and the corresponding plans are prescriptive and must be obeyed. However, in the networked enterprise environment, each cooperative enterprise is independent and cannot be directly controlled, so prescriptive planning and control is not feasible. Because each enterprise's production planning and control decisions are affected by the production planning and control decisions of other enterprises, they must cooperate with each other, at this time, consultation is the only way. The consultation has not only maintained the independence of each enterprise, but also can achieve the goal of mutual cooperation. The consultation is not only embodied in the negotiation of the cooperation contract, but also in the process of negotiation and planning control consultation, which are not involved in the traditional production planning and control.   Yongkaida APs to solve the scheduling problems that cannot be satisfied by ERP Http://www.yukontek.com,APS Production planning management expert 400-076-7600,021-68886010
